CompTIA Cloud Essentials+ Practice Exam

The exam practice test questions from the Sybex book.

The CIO wants to reduce the cost of network ownership for the company, specifically for app licenses. Which service model should you recommmend to her?

The software as a service (SaaS) model provides software applications, including apps such as Google Docs and Microsoft Office 365. Anything as a service (XaaS) is too broad and can mean a combination of multiple services. Platform as a service (PaaS) provides development platforms for software developers. Infrastructure as a service (IaaS) offers hardware for compute, storage, and netowrking functionality.

Which of the following is a potential outcome of implementing a multicloud environment for your company?

Multicloud means using multiple cloud vendors for different service models, such as SaaS and IaaS together. This provides additional flexibility. The downsides are that it can be more complex to manage and cost more. The security will probably be a little worse than using a single cloud provider, due to having multiple systems to manage. A combined public and private cloud is a hybrid cloud.

You are buying new cloud services. The internal network administration team is worried about cloud access from different OSs, such as Windows, macOS, and Android. What should you tell them?

Broad network access means that clients of different types, such as laptops and mobile devices, running different operating systems (OSs), such as Windows, macOS, and Android, can all access network resources. Self-service is the cloud characteristic that allows clients to get additional resources without supplier intervention.

The company CIO asks you to ensure that the new cloud solution provides fault tolerance. Which aspect of cloud design does this refer to?

Fault tolerance and redundancy are synonymous terms in cloud computing. Redundant systems can provide backups for other systems, so if one fails, the other can take over. Redundancy can help ensure high availability of resources. High availability means that the system is always or almost always available and is often specified in the SLA by the number of nines of uptime that are guarateed. Disaster recovery is for after a system fails. Shared responsibility is the cloud security model.

Which of the following are examples of IaaS that a cloud provider might offer? (Choose two.)

Infrastructure as a service (IaaS) offers a client company capacity such as processing power (compute resources), storage and network services. Applications are offered as part of software as a service (SaaS), and a database is typically offered as database as a service (DBaaS).

Which of the following should you ask for in an SLA if you want to ensure the highest availability of resources for cloud users?

Availability is expressed in terms of nines. More nines means more availability. Four nines means 99.99 percent uptime. Some CSPs offer smaller increments with a five at the end. For example, four nines five means 99.995 percent availability, which is higher than four nines. Four nines five means no more than 4.32 seconds of downtime per day.

When shopping for public cloud services, the CSP tells you that if your company needs more or fewer resources, the CSP can instantly accommodate that. What cloud characteristic does this refer to?

Elastic means that cloud resources can grow or shrink as a client's needs change. Self-service is when the client can get more resources without supplier intervention. Broad network access refers to the cloud being accesible regardless of client device. Availability means that resources are always (or almost always) accessible.

Your CSP makes daily backups of important files and hourly backups of an essential database, which will be used to restore the data if needed. Which aspect of cloud design does this represent?

Backups are a form of disaster recovery. Redundant systems are typically online and do not need to be activated or restored. High availability means that resources are almost always accessible. A recovery time objective (RTO) defines how long services can be down before they are restored, in the event of a disaster.

Which of the following best describes the purpose of the shared responsibility model?

The shared responsibility model defines security duties within the cloud. The CSP is responsible for the security of the cloud, and the client is responsible for security in the cloud.

Which of the following cloud service models best supports a software development team with members in the United States and Japan?

PaaS provides software development tools for development teams. It allows geographically disperesed teams to easily operate as one. IaaS provides hardware capacity. SaaS offers web-based apps such as Google Docs. DBaaS is for databases.

You are negotiating an SLA with a CSP. Which two things need to be included as part of the recovery objectives?

Disaster recovery plans should should include a recovery point objective (RPO) and a recovery time objective (RTO). The RPO specifies how old data can be when it's restored to be useful to the company. The RTO specifies how long services can be down after a disaster, before being restored. There are no recovery process or recovery cost objectives.

In the cloud security model, who is responsible for securing access management and firewall configurations?

In the shared security model, the CSP is responsible for the security of the cloud, and clients own security in the cloud. Customer data, access management, and firewall configurations are exampes of items in the could and are therefore the client's responsibility.

Which of the following cloud deployment models offers the best scalability and cost effectiveness?

Public clouds, such as Microsoft Azure and Amazon Web Services (AWS), offer the best in scalability, reliability, and cost effetiveness. Private clouds do not offer as muc hcost effectiveness. Community clouds and hybrid clouds are between public and private in terms of scalability and cost effectiveness.

Which of the following best describes an RTO?

The RTO is the maximum amount of time a system can be offline in the event of a disaster. Maximum data age is the RPO. There are no common disaster recovery terms associated with cost or chain of command.

Which of the following is NOT a common characteristic of public clouds?

Cloud services should lower the cost of network operations and software use for companies. Cloud characteristics include elastic, self-erivce, scalability, broad network access, pay-as-you-go, and availablity.

Your company uses a financial transactions database that updates frequently. If a natural disaster occurred, any data backup older than one hour would not be useful to the company. To ensure that backups are always more current, what needs to be specified in the disaster recovery plan?

The RPO defines the maximum age of files that must be recovered from backups in order to restore normal operations. In this case, the RPO needs to be less than an hour. The RTO specifies how long services can be down in the event of a disaster. There is no TSO in disaster recovery plans. The service level agreement (SLA) usually contains a section for the disaster recovery plan.

Your network hardware is outdated and needs to be replaced. The CIO suggests using the most cost-effective cloud solution. However, he insists that the company database remain 100 percent controlled by your company. Which solutions is the best choice?

The most cost-effective cloud solution is a public cloud, but the best security comes with a private cloud. Since both elements are needed in this case, the best solution is most likely a combination of the two or a hybrid cloud. A community cloud is one that is owned by multiple organizations with shared interests.

Your data science team runs complex simulations that require more compute resources. They do about one simulation per month, and it takes one to two days. You want to ensure that the team has available compare resources but that you only pay for the resources when they are in use. Which cloud characteristic do you need?

In a pay-as-you-go model, clients pay only for resources that are used. Scalability and elastic can refer to the ability to the ability to get more resources, but the key component of this question is paying only for used resources. Availability means that resources are always (or alsmost always) accessible to clients.

Which of the following is NOT a type of redundancy typically available in public cloud solutions?

Redundancy means having a backup of existing systems or processes - if one fails another can take over. Common redundancy types include hardware, network, geographic, process, software (apps), and data. OSs are easily replaceable, so redundant ones are not usually needed.

Several universities want to band together to get cloud service. They want to share scholarly research but also take advantage of common cloud-based productivity apps. Which solution is the best option for their needs?

A community cloud is one that is essentially public but is shared between multiple organizations. In a sense, it's like a public cloud but has better security. Public clouds are accessible to everyone. A private cloud is for only one organization. Hybrid clouds are both public and private.

Your company needs to upload a large, offline backup archive to the new cloud service. What type of storage is best for this archive in the cloud?

Object storage is the best solution for large archives that do not need to be modified often. File storage is for smaller storage solutions and individual computers. Block storage is good for databases. Hot storage is more expensive than cold storage and is not recommneded for archives that do not need frequent access.

A CSP is configuring access to your cloud-hosted web server. Which of the following services will help users locate your web server on the Internet?

Domain Name System (DNS) resolves host names to IP addresses; it's what will help end users locate your web server. Software-defined networking (SDN) abstracts network hardware in the cloud. Software-defined storage (SDS) allows for the virtualization of cloud storage solutions. A content delivery network (CDN) is load-balancing for websites.

Which of the following protocols is used with a web browser to securely access cloud storage?

The Hypertext Transfer Protocol Secure (HTTPS) is used in conjunction with a web browser to access cloud resources. Remote Desktop Protocol is used to remotely access a Windows-based computer, and SSH is used to remotely access a Linux-based one. Hypertext Transfer Protocol (HTTP) is not secure.

A network administrator needs to remotely log into a cloud-based LInux server to perform some administrative tasks. Whcih access method should she use?

The Secure Shell (SSH) protocol is used to remotely access a Linux-based server. Remote Desktop Protocol (RDP) is used to acces Windows-based servers. Direct connect is for a company to directly connect its network to the CSP's network. HTTPS is used in conjunction with a web browser to access cloud resources.

Which of the following cloud storage types is designed to provide the fastest access to data and will be more expensive per gigabyte than other options?

Hot storage is designed to be readily accessible at all times. It is more expensive than cold storage, but access time is much faster. Block and object are storage types. Block will be a little faster for structured data, and object storage is better for unstructured data. One won't necessarily be more expensive per gigabyte than the other.

You are migrating to the cloud. Which solution should you use to handle spikes n the need for compute resources?

A load balancer is designed to spread work among multiple computers in order to maintain or improve performance. It's also scalable and can handle spikes in network traffic. DNS resolves host names to IP addresses. A firewall is the network or computer's security device. DSN abstracts the cloud networking hardware.

Which of the following technologies is used to create a secure point-to-point tunneled connection over the Internet?

A virtual private network (VPN) is a secure point-to-point tunnel over a public network such as the INternet. RDP is ued to access Windows-based servers. The SSH protocol is used to remotely access a LInux-based server. HTTPS is used in conjunction with a web browser to securely access cloud resources.

The global sales team needs to ensure that all regional teams have quick access to the same selling materials, including sizzle videos and PDFs with pricing. Which of the following should be implemented to enable this?

The sales team needs a CDN to ensure quick access to the same materials globally. SDS allows for the virutalization of cloud storage solutions. DNS resolves host names to IP addresses. SDN abstracts network hardware in the cloud.

Your company is migrating its network storage to a cloud-based solution. Which of the following are most likely to be the least expensive storage options? (Choose two.)

Cold storage and tapes are likely to be the least expensive, because neither are designed to be online for quick and immediate access. Hot storage will be the most expensive. Warm storage will be somewhere in between hot and cold.

The cost for your cloud storage keeps growing, and you need to find ways to reduce those costs. Which of the following can help you do that? (Choose two.)

Compression and deduplication are technologies that save space by reduncing redundancy wihtin files or between files. They can both reduce the needed storage space and help lower costs. Capacity on demand means that you can get additional storage space as needed. Object and block storage do not inherently help you save space and reduce costs.

Which cloud concept makes networks more agile by separating the forwarding of network packets from the logical decision-making process?

SDN makes networks more agile and flexible by seperating the forwarding of network packets (the infrastructure layer) from teh logical decision-making process (the control layer). SDS seperates the physical storage of data from the logical data storage controller. DNS resolves host names to IP addresses. A CDN is like load balancing for web content.

Your company just signed with a new CSP and needs to upload a large customer information database to the cloud. Once it's uploaded, employees will continue to access and update the database. Which storage type is recommended?

Block storage is the best option for databases. Object storage is great for unstructured data or large archives that don't need to be accessed frequently. File storage is goodfor PCs. Cold storage would not be appropriate, because it has longer latency times to access and update data.

You are negotiating cloud services with a CSP. You need to ensure that your organization can get more storage space without CSP intervention. Which service do you need?

Capacity on demand allows clients to get extra storage space instantaneously, or at least very quickly. SDS separates the physical storage of data from the logical data storage controller. SDN makes networks more agile and flexible by separating the forwarding of network packets (the infrastructure layer) from the logical decision-making process (the control layer). A CDN is like load balancing for web content.

Which of the following technologies lets a cloud provider create one logical storage volume from multiple physical storage devices?

Software-defined storage separates the physical storage of data from the logical control over drive configuratoin, independent of the underlying hardware. This means storage volumes can be created from multiple physical devices. DNS resolves host names to IP addresses. SDN makes networks more agile and flexible by separating the forwarding of network packets (the infrastructure layer) from the logical decision-making process (the control layer). A CDN is like load balancing for web content.

Which cloud technology makes use of an edge server?

A CDN is like load balancing for web content. It uses edge servers to replicate data that's on teh web server, serving the data to users closer to the edge server than to the web server. SDS separates the physical storage of data from teh logical control over drive configuration, independent of the underlying hardware. This means storage volumes can be created from multple physical devices. DNS resolves host names to IP addresses. SDN makes networks more agile and flexible by separating the forwarding of network packets (the infrastructure layer) from the logical decision-making process (the control layer).

Your company has 500 users who need access to cloud resources during all working hours. Due to the nature of their work, there can be little to no latency. Which connectivity type is the best choice?

Direct connect is used to provide a physical connection between your company's on-site network and the CSP's network. It's the best connectivity option for a large number of users. A VPN can also work for a large number of users, but it will use the INternet as its connection medium, so it will be a little slower than direct connect. HTTPS is for single users to access cloud resources using their web browsers. RDP is for a user to remotely access a Windows-based server.

You need to have multiple users connect simultaneously to cloud resources through a single connection. Which two options allow this type of configuration? (Choose two.)

A VPN can be used to set up a point-to-point connection between a corporate network and a CSP. Direct connect means directly connecting the client's internal network to the CSP's network. Both allow multiple users to use the connection simultaneously, RDP, SSH, and HTTPS are for single-user connections only.

A network administrator tells you that he needs to create a DMZ in the cloud. Which of the following cloud-based services will help him do this?

A firewall is a hardware or software solution that serves as a network's security guard. It's also what lets you create a demilitarized zone (DMZ), which is semi-public, semi-private network. SDN abstracts the networking hardware and separates routing from routing logic. A load balancer spreads work among servers. DNS resolves host names to IP addresses.

Your company's in-house data center has a small storage area network that will be migrated to the cloud. Which of the following cloud storage types is most likely to resemble the way data is stored in the SAN?

Most SANs use block storage to store data. Block storage is also commonly used for databses and by VMMs. Load balancing spreads work around to multiple servers. File storage is used for small-scale storage, such as on PCs. Object storage is for unstructured data.

You are moving your company's network to the cloud. Network administrators want to know if they can still manage Linux and Windows-based servers. Which of the following are designed specifically for these tasks? (Choose two).

The SSH protocol is used to remotely access a Linux-based server, and RDP is used to access Windows-based servers. HTTPS is used in conjunction with a web browser to securely access cloud resources. A VPN is used to create a secure point-to-point connection over an unsecure network, such as the Internet.

A network administrator wants to implement VDI in your future cloud solution. Which of the following is NOT an implication of implementing VDI?

Virtual desktop infrastructure (VDI) is when user desktops are created inside a virtual machine (VM) located on a server, VDI can centralize administration, increase security, and allow users to access their desktops remotely, VDI most often reduces the total cost of ownership and does not result in higher costs.

Company A has a software development team with members located in Geneva and others in Chicago. Which cloud service will best help them manage a project that all of them are working on?

For the team to work together better, they should use collaboration software. Using it, they can video conference and share files with ease. Self-service refers to getting more cloud resources without CSP intervention. An autonomous environment is one in which human intervention is not needed, such as a self-driving car. Blockchain is a secure ledger system.

Your company is trying to save money by using cloud services. Which of the following is most likely to help reduce the costs of software development?

Microservices describes the breaking down of a larger program into smaller pieces-literally small services. It can reduce the cost of software development and ownership. Federation is a security mechanism. Machine learning (ML) and artificial intelligence (AI) are two services that can help with data analytics.

You have been asked to perform a cloud assessment for your company. Which of the following describes an appropriate order for conducting assessment tasks?

The first thing to do when conducting a cloud assessment is to determine current and future requirements, and you do so by contacting key stakeholders and asking the right questions. After that, you can run a baseline to see where current performance is. That will let you perform a gap analysis to understand where the business and technical situations fall short. Finally, at the end you will create documentation and diagrams.

Your company recently signed up for a Microsoft Office 365 subscription. The network administrator wants to make it so that users only have to type in their login information once and don't need to log into the local network and Microsoft's cloud separately. What service does she need to implement?

Federation allows users to perfrom a single sign-on across different companies' security domains, whereas single sign-on refers to users logging into multiple systems within the same security domain. In this case, since it's the company's local network and Microsoft's cloud, it will be federation. Self-service refers to getting more cloud resrouces without CSP intervention. Multifactor authentication (MFA) means that users need to provide more information besides a username and password to log in, such as a temporary security code.

A network administrator who is part of the cloud assessment team mentions that the average server CPU utilization is at 40 percent. What do you use to determine if this is acceptable performance?

A benchmark is a standard or point of reference for comparison. It should be used to determine whether performance is acceptable. A baseline can give you a performance read but doesn't provide context. A technical gap analysis will help you determine whether the company has teh technology needed to implement cloud services or what is needed to do so. Compute reporting will give you CPU and RAM utilization from the CSP.

In preparation for a cloud migration, your manager asks you to run a gap analysis. Which of the following is NOT a likely outcome of a gap analysis?

Key stakeholders should input into a cloud assessment, but their feedback is particularly valuable when gathering current and future requirements. A gap analysis can be technical, business-related, or both. A gap analysis can help find compatibility issues, policies that are not being met, and priority calls that need to be made.

A small company needs to set up a security surveillance system to protect its building. Which cloud-based technology will the security system most likely take advantage of?

Security systems are an example of a technology that relies upon the Internet of Things (IoT). VDI creates virtual user desktops. SSO is a security mechanism for computer logins. AI is when computers perform complex, human-like tasks.

The company CIO approaches you and asks you if the company should implement blockchain in the new cloud environment. Which of the following is the best explanation you can give on what blockchain is?

Blockchain is an open, distributed ledger that can securely record transactions between two parties in a verifiable and permanent way. The most famous example of blockchain usage is for the cryptocurrency Bitcoin, but Bitcoin and blockchain are not the same thing. Blockchain is not an authentication system, nor does it lower the TCO for applicatoin DevOps.

Your company recently merged with another, and the networks have been combined into a cloud solution. Users need to access multiple resources from different systems within the same security domain. What should your company implement to make access as easy as possible for users?

The purpose of SSO is to give users access to all of the systems, resources, and apps they need with one initial login. Federation is like SSO but applies across security domains. MFA means that users need to provide multiple pieces of information to log in - it makes access harder, not easier. Self-service referes to getting more cloud services without CSP intervention.

Company A wants to assess the possibility of migrating to the cloud. What should they do to determine how much of their current server storage capacity is being used?

A baseline tells the company how its systems are currently performing. A benchmark compares performance numbers to an established standard or point of reference. Determining current and future requirements tells you what is needed but does not tell you about current performance. A gap analysis helps determine what gaps exist between current performance and desired performance standards.

A member of your company's purchasing team is negotiating cloud services with a CSP. Over the course of the first year, which of the following would likely represent a cost savings over other types of payment models?

Subscription-based pricing, or subscription services, usually offers a discount over pay-as-you-go models, but it also means your company is locked into a contract for the length of the subscription. Self-service refers to being able to get more cloud resources without CSP intervention. High availability is a feature of clouds (and more guarenteed availability will cost more), but it is not a cloud payment model.

To increase security of your company's cloud resources, the administrator decides to require users to enter a password and also a randomized security code to log into the cloud. What cloud service does teh administrator need to enable?

Requiring users to enter multiple pieces of information to be authenticated is called MFA. SSO requires a username and password and allows access to multiple resources within a security domain. VDI is for creating virtual user desktops on a server. Federation is like SSO, but for across organizations.

You are performing a cloud assessment for your organization. It's time for you to determine which capabilities can be offloaded to the cloud and the level of support services needed. Which of the following assessments should you perform?

A feasibility study can hep determine whether it's possible for. company to move to the cloud. This includes determining which capabilities can be offloaded to the cloud as well as the level of support services needed. A gap analysis tells a company what the gap is between their current levels of business or technical readiness and where they need to be. A baseline is a measure of current performance. Determining current and future requirements is done before figuring out what can be offloaded or what support is needed.

When setting up a new cloud service, you want to ensure that you can get more storage space quickly without needing to call or email the CSP. What cloud service allows you to do this?

Self-service means clients can get more cloud resources automatically without CSP intervention. SSO is a security mechanism. Subscription service is when a company pays for a level of services for a specified period of time. Autonomous environments are when computers or machines perform complex human-like actions without human intervention.

One of the company's developers is creating a software package that can identify human faces and mine footage from security cameras to determine whether someone is suspected of a crime. Which type of technology is best suited for this task?

With ML, data can be fed to a computer, and it will learn from it and adapt. ML is a specialized form of AI and is perfect for facial recognition programs. Big data refers to unstrcutured data; mining it coul help find data or data patterns. Blockchain is a secure ledger system. AI can make human-like decisions, but it can't learn, which is needed for facial recognition.

The sales team needs to find better, faster, and cheaper ways to engage with potential customers. Which cloud service should they implement?

Digital marketing is when companies market products or services using digital technology. Examples include email campaigns and social media posts. Big data refers to unstructured data. Blockchain is a secure transaction ledger. IAM refers to capabilities used to authenticate users.

You are performing a cloud assessment. What is the final step to take in the cloud assessment process?

The final thing to do in a cloud assessment is to ensure that documentation and diagrams have been created. Conversations with the key stakeholders and CSP should be documented. Service coverage and locations should be diagrammed as needed. Engaging key stakeholders should happen very early in the process, as should feasibility studies and gap analyses.

A software developer at your company said he just used the cloud to place his program and all needed library files into one package. Which cloud service is he referring to?

Containerization is a fancy term meaning that all items are placed into a container. Developers can do this with a program they have created along with all components needed to execute that program. Microservices is a way to build apps by breaking them into smaller components. Blockchain is a seure digital ledger. Federation is a security mechanism.

Your company is debating which cloud-based data analytics solution to implement. Which of the following statements is NOT true when comparing AI to ML?

ML is a form of general AI, not applied AI. Applied AIs are designed to perform a specific, smart, human-like activity. And, AIs can only react to conditions they have been programmed to react to. ML learns through the use of neural networks.

For corporate tax purposes, which of teh following types of expenditures would be depreciated over several years? (Choose two.)

Physical, tangible assets such as a building (or building expansion) and servers are examples of capital expenditures. Capital expenditures are depreciated over the lifetime of the asset. Employee salaries and property taxes are operating expenditures, which are deducted in the year they are paid for.

Sue, an IT employee, tells her manager that she wants to create a five-year plan to fulfill some career goals. What type of plan does Sue need?

Professional development refers to a long-term educational process focused on employee growth. Training plans are shorter-term and focus on acquiring a specific skillset to perform a job. Managed services and support are professional services that you might buy to help support the cloud.

Your company has decided to move to the cloud. However, a research and development database has high security needs and will be kept on-premises. What type of migration is best for this situation?

A hybrid migration can be one of two migration can be one of two things: either a combination of rip and repces or life and shift or one where some assets remain on-premises. Rip and replace means that software gets re-created to take advantage of the cloud as it's migrated. Lift and shift means that assets are taken as is from the current site and moved to the cloud. Phased migration means that the migration happens in stages over time.

You have just approved an RFP from a cloud vendor. Which of the following could be logical next steps to move to cloud services? (Choose two.)

After the request for proposal (RFP) has been approved, there could be a few logical next steps. One might be to verify the statement of work (SOW) and SLA and then sign the contract and migrate. Another could be to run an evaluation such as a pilot or proof of concept (PoC). A request for information (RFI) comes before the RFP, and the RFQ is in lieu of an RFP. Lift and shift is a type of migration and would not be started until the contract has been signed.

Your company is migrating to the cloud. Users need both commercial and proprietary software packages, both types will be migrated. The migration needs to happen quickly. Which types of migration are most suited for this situation? (Choose two.)

The lift and shift, where data and applications are picked up as is and moved to another location, is the quickest and cheapest migration option. It's also appropriate for commercial apps that can't be reprogrammed. In a rip and replace migrations are not fast. A hybrid is a combination of the two, or a migration where some items stay in the original location. Phased migrations happen over time.

The IT department is going to run a small cloud evaluation in the production environment to see if there are any app compatibility issues. Which type of evaluation will they be running?

A pilot is a small-scale initial rollout of a solution into the production environment. The intent of a pilot is to test the solution among a small number of users to understand if it works on existing production hardware and apps. A PoC and PoV are run in test environments. Managed services are professional services used to support cloud installations.

Your organization is considering moving from an on-premises data center to the cloud. A finance manager asks about the benefits of using a pay-as-you-go model for services. Which of the following is a benefit of pay-as-you-go?

On-premises data centers are capital expenditures, which come with high up-front costs. Cloud-based services are operating expenditures, which generally do not cost as much up front. Capital and operating expenditures can both be fixed.

Your company is debating potential cloud solutions. Which of the following are benefits of going with a proprietary cloud platform? (Choose two.)

Two choices when looking for a cloud are open source technology and proprietary technology. Proprietary cloud will give large company support, usually have more features, and have clear SLAs. Open source clouds are less expensive, provide greater development flexibility, have faster updates, and don't have concerns with vendor lock-in.

After migrating to the cloud, your company hires external technical expertise to perform cloud optimizations and troubleshooting. What is this an example of?

Hiring external professional services such as tech support is an example of managed services. Often these are contracted through a MSP. Professional development is long-term career development of internal employees, who are human capital. A SLA specifies metrics for determining whether the CSP is delivering what is expected.

Your company is moving all IT infrastructure to the cloud. The company has a five-year database license. Which of the following can save the company money on migrating the database to the cloud?

BYOL allows for the transfer of existing licenses from one app, user, or location to another. If the database license can be used as BYOL, then the company does not need a new license, which saves money. A subscription license might or might not be transferrable. A pilot and PoV are evaluation types.

A CSP has just completed an RFP, and you have accepted it. Which of the following is the most appropriate next step?

After accepting an RFP, the next step is to continue defining what the service provider will deliver. This is done through an SOW. The SOW might be part of the RFP, but it might not be. Once the SOW is agreed to, then the SLA can be finalized. A request for quotation (RFQ) is an alternative to an RFP, if you are looking for the price on a standard solution. You won't sign the contract until the SOW and SLA are agreed to.

You are acquiring new cloud-based software for your company. The developer will only sell you the software on a subscription basis. Which of the following is NOT an advantage of subscription-based pricing?

A subscription is for a certain time period, such as one year. Consequently, the user will need to pay to continue to use the software after the license expires. Subscriptions should offer no upgrade costs for new features (which also means users should always have the newest version at no extra cost), smaller up-front license costs, and device flexibility.

A manager in your company wants to ensure that the cloud solution you are proposing will help with TTM. What does the manager mean by this?

Time to market refers to the ability to get a product or service from the idea stage to selling it as quickly as possible. It does not refer to delay or data trasnfer rates to or from the cloud or the number of cloud evaluations needed.

You are looking for a new CSP. Your company wants to ensure that any intellectual property rights are clearly owned by the company and that the CSP has no stake in them. Where will this be specified?

The contract will specify terms of service, which include items such as intellectual property (IP) rights. The billing statement shows how much is owed. An SOQ specifies the work to be done by the CSP, and the SLA calls out metrics to determine whether the CSP is delivering on the SOW.

You company is evaluating payment options for a new CSP. Which of the following could be an advantage of going with subscription-based pricing for the cloud as opposed to pay-as-you-go? (Choose two.)

Subscription-based models might come with discounts and usually offer fixed costs. However, they lock a company into a contract for a specified amount of time; cancellation will usually incur a penalty. Both subscriptions and pay-as-you-go are operating expenditures.

You have received several RFIs from potential cloud vendors. Now, you want to know how much it will cost for a standard set of four VMs. What should you ask for next?

If you need a price quote for a standard set of services, you need an RFQ. An RFP is a more detailed document for more custom solutions. PoC and PoV are two types of cloud evaluations.

You are seeking to pilot a new cloud-based service and have several CSPs to choose from. Which of the following should NOT be selection criteria for choosing which company to pilot with?

When setting up a pilot, successful completion should not be a selection criteria or the ultimate goal. The goal of the pilot is to learn whether a capability works as it's supposed to. Therefore, usability, data security, and latency are all important things. But failure of a pilot can actually mean success if it helps your company avoid serious losses.

You are creating an RFI to seek out potential CSPs. Which of the following is NOT recommended to include in the RFI?

The RFI is an initial fact-finding request. It should be a high-level request, with clear objectives, processes, timelines, and next steps. A template for the CSP to fill out is also helpful. An SOW is too detailed for an RFI.

Your company has decided to move it's on-premises IT infrastructure to the cloud. Because of the cost involved, management decides to move some services this fiscal year and move the rest of the services next fiscal year. Which type of migration will you be performing?

Phased migrations are ones that occur over time. In a rip and replace, software needs to be redeveloped to take advantage of cloud services. The lift and shift, where data and applications are picked up as is and moved to anotehr location, is teh quickest and cheapest migration option. A hybrid is a combination of the two, or a migration where some items stay in the original location.

You have moved to the cloud and are now seeking out professional services. Which of the following is NOT an example of cloud professional services?

There are four professional services to be aware of: time of market, skill avilability, support, and manged services. Running a PoC is a type of evaluation. Using developers who are skilled in a language is an example of skill availability. Data backups are a form of support, and developing and selling more quickly refers to time to market.

The CIO wants to cut the cost of the instances that are running in the cloud. The instances that have the highest cost are all produciton instances and are required to be on 24/7. Which instance type should you look into utilizing?

Since the instances are production and required, reserved is themost cost effective. On-demand is the most expensive option. Spot is the cheapest, but is not designed for production instances. Quick is not a type of instance.

You have been tasked with creating a WordPress site using open source software and making the primary site highly available within a region. Which option of software and locality would fulfill the requirements?

Option A is the only option that satisfies all the requirements. Options B and C use pay-for-use software fro mMicrosoft. Option D uses free-for-use software, but the zones are in two different regions.

You are designing the infrastructure for an e-commerce website that plans on selling sporting apparel for footbal (soccer) clubs around the globe. Which technology should you look at that offers the lowest latency and best performance for your shoppers?

A CDN will offer lower latency aroud the globe. Immutable infrastructure should be sued but dows not offer any of the requirements. Synchronous replication cannot be used around teh globe. Autoscaling should also be used but does not offer any of the requirements.

You need to update all the Windows Servers fro Server 2012 R2 to Server 2016. You decide the best course of action is to do an in-place upgrade and install Server 2016 over the top of Server 2012 R2. Is this a recommended course of action? Why or Why not?

NO, because you are performing an in-place upgrade, which goes against the concept of disposable resources. Option A may save costs temporarily but has increased risk with an on-prem upgrade. Option B is not correct because Server 2016 being compatible is not enough. You have not performed any testing. D is not correct because the reason for NO is not sufficient; load testing is not testing the upgrade process.

You have decided to test your application on Server 2016 and want to deploy new instances. Which technologies will you use to speed up the deployment and make sure all the servers are deployed in procedural and repeatable fashion? (Choose two.)

Bootstrapping and golden images are technologies that will speed up the deployment and in a repeatable fashion. API does not address any of the requirements. Tagging should be used ot fulfill auditing requirements, but those are not mentioned in the question.

Which of the following cloud resources will have a cost associated with any transfer of data out of the CSP's infrastructure? (Choose all that apply.)

Object storage and network usage will have costs associated with the transfer of the data out of the CSP infrastructure. Compute and block storage transfers will be local to the instance itself. Any transfer of data out from the compute will be counted as network costs.

Which storage offerings will have a cost associated with the amount of data stored, even if the resource using the storage is powered off? (Choose all that apply.)

All storage offerings including object, block, and file storage will have a cost associated with the amount of data storage, even if resources are powered off (the data is still being stored). All storage is replicated in some manner in the cloud, but there is no storage offering called replicated.

Your legal department wants to start using cloud resources. However, since all of their work will be associated with legal cases, they need an accurate usage and billing breakdown to bill the clients. What are you being asked to implement?

Chargebacks is the process of creating the tagers needed to provide accurate and detailed billig to be able to bill a third party. Right-izing deals with the process of moving to the cloud. Maintenance is services that are purchased from the third parties. You can set up an alert or monitoring for billing, but tha tis not specific to the question.

The development team has added a new search feature that has never been tested before. Which testing process is more important than the others?

The new feature is a search funciton. Searches require increased CPU and memory usage. Load testing will be needed to determine which resources will need to beincreased. Regression testing should be done, but since this is a new featuer, there are no previous bugs concerning searches that can be performed. Sandbox testing should have already been performed. Penentration testing is important from a sercurity perspective but doers not address the requirement in the question.

Your manager wants to do a lift-and-shift migration from on-premises servers to cloud servers. He has determined that the cloud will save money. Which process is the manager forgetting to complete?

Right-sizing is the process of evaluating current on-premises servers for need and sizing before moving to the cloud Templating is used for provisioning servers. Autoscaling is sizing resources in the cloud. Orchestrating is part of configuration management once already in the cloud.

The CFO wants to be notified whenever the monthly estimated costs reach $2,000. You will set up what to notify once the threshold is met.

Alerts can perform actions when events occur or when thresholds are met. Logging does not perform notifications but can be used to trigger an alert. API can be used to set up alerts. Autoscaling is used for increaseing or decreasing resources.

What has become synonymous with DevOps and is referred to as a pipeline and used in the real world by organizations?

Continuous integration continuous delivery (CI/CD) is the pipeline that is used in the real world. Continuous integration and continuous deployment are used but not in the real world because of the impact on user experience. Options A and D are not real terms.

Which of the following cloud deployment models offers the best scalability and cost effectiveness?

Public clouds, such as Microsoft Azure and Amazon Web Service (AWS), offer the best in scalability, reliability, and cost effectiveness. Private clouds do not offer as much cost efectiveness. Community clouds and hybrid clouds are between public and private in terms of scalability and cost effectiveness.

A blue/green deployment is a deployment used priarily when doing what on production infrastructure?

Blue/green deployment is used for upgrades and patching. Regression and sandbox testing uses different infrastructure than production. Development uses infrastructure that is seprate from production.

Which of the following is not a common characteristic of public clouds?

Cloud services should lower the cost of netowrk operations and software use for companies. Cloud characterisitcs include elastic, self-service, scalability, broad network access, pay-as-you-go, and availabilty.

Your company uses a financial transactions database that updates frequently. If a natural disaster occurred, any data backup older than one hour would not be useful to the company. To ensure that backups are always more current, what needs to be specified in the disaster recovery plan?

The recovery point objective (RPO) defines the maximum age of files that must be recovered from backups in order to restore normal operations. IN this case, the RPO needs to be less than an hour. The recovery time objective (RTO) specifies how long services can be down in the event of a disaster. There is no TSO in disaster recovery plans. The service level agreement (SLA) usually contains a section for the disaster recovery plan.

API integration can be used to manage cloud resources by which of the following methods? (Choose all that apply)

API calls are used to manage cloud resources via the web, CLI, and SDK. SSH is a management software of Linux systems.

What storage type is used for the OS boot partition of an instance running in the cloud?

Block storage is the sotrage type used for all OS boot partitions. File and object sotrage can be sued in an instance, but due to their shared nature, neither one can be used as a boot partition. HDD is a type of block storage, but so is SDD. It might be the underlying technology.

What is the process of combining a series of automation steps into a repeatable process that can be audited?

Orchestration is the combination of seperate automation tasks. Automation is what we are trying to combine. Autoscaling can be orchestrated but is specific. Patching should be automated but is also too specific.

Which of the following are examples of free-for-use license types? (Choose all that apply).

Both Linux and Apache are open source and free for use. Windows and Cisco ASA are commercial and pay for use.
