Code division multiple access (CDMA) means that the handset is directly managed by the provider and there is no removable SIM card.

ECC RAM

A server system uses a method where each transfer performs a hash calculation on the data value and stores it as an 8-bit checksum. This can detect and correct single-bit errors and allow the PC to continue functioning normally. What is this method called?

A technician uses error correction code (ECC) RAM for workstations and servers that require high reliability.

Virtual RAM, also called virtual memory, is not just used to supplement RAM with swap space.

Small outline DIMM (SODIMM) is the smaller form factor packaged for laptop RAM. The memory typically fits into slots that pop up at a 45-degree angle to allow the chips to be inserted or removed.

Dual-channel memory controllers effectively have two 64-bit pathways through the bus to the CPU, meaning that they can send 128 bits of data per transfer rather than 64 bits.

SOHO

A contractor working for a managed services company works fully remote from their residence. They have multiple desktops, printers, and even some Wi-Fi access points set up. What type of network is this considered?

A small office home office (SOHO) LAN is a business-oriented network, potentially using a centralized server in addition to client devices and printers, but often using a single networking appliance to provide LAN and Internet connectivity.

A wide area network (WAN) spans multiple geographic locations. One example of a WAN is the internet, a global network of networks.

A wireless local area network (WLAN) uses radios and antennas for data transmission and reception. Though there are some Wi-Fi access points, not all devices are wireless.

A metropolitan area network (MAN) can mean a specific network type covering an area equivalent to a city or other municipality.

HDD

What kind of storage media can have grinding and clicking as a diagnostic tool?

A hard disk drive (HDD) has moving platters and arms. These mechanical parts can start making grinding or clicking noises as they fail.

A solid-state device (SSD) does not have moving parts. Instead, SSD uses flash memory technology to implement persistent mass storage. As a result, risks from failure due to mechanical shock and fear are generally lower.

Random access memory (RAM) does not have moving parts to fail. RAM is the nonpersistent memory used for running programs and open data files.

Non-volatile read access memory (NVRAM) does not have moving parts to fail.

A support technician replaces a Wi-Fi card in a laptop. The following day, the laptop user states that the company's Wi-Fi network signal is weaker than it was before. What does the technician find to be the likely problem?

The antenna is not connected.

When replacing a Wi-Fi card, it is important to remember to connect the antenna. The connection is usually a wire with a terminating end that snaps onto the card.

A Wi-Fi card is seated into a laptop and is usually a peripheral component interconnect express (PCIe) type connector. Having the card seated incorrectly would render the Wi-Fi card unrecognizable and not function at all.

Devices within a computer require software drivers to function. Since the system identified the card properly, then the support technician installed the correct drivers.

There are varying specifications for Wi-Fi. Since the Wi-Fi is receiving a signal, the Wi-Fi card is compatible with the company's Wi-Fi system.

Virtual LAN

A growing company is looking to move away from an outside vendor for payment processing and would like to do it in-house. As a part of securing the data on these computers, what foundational infrastructure solution should the company implement to keep this data separate from the rest of the company's internal network?

A virtual LAN (VLAN) is a logical network segment using a feature of managed switches to segregate network traffic. This would be the first step to separating network traffic for the given scenario.

A virtual private network (VPN) enables mostly remote hosts to connect to the LAN without being physically installed at the site.

In the Domain Name System (DNS), an A record resolves a host name to an IPv4 address. This would not provide any added security.

A dynamic host configuration protocol (DHCP) scope is a range of consecutive IP addresses in the same subnet that a DHCP server can lease to clients. The company may not use this if all the hosts have static addresses.

Toner Probe

After discovering an unlabeled wall port in an office, a technician would like to label it appropriately. Not knowing where the permanent link patches into specifically, they know which IT closet it would run to, as all the other permanent links in the same area run to the same closet. When connecting a laptop, there appears to be a successful connection. Which tool would be most helpful for the technician to use?

A toner probe detects the signal and follows the cable over ceilings and through ducts, or identifies it from the rest of the bundle. A technician uses this along with a tone generator, applying a continuous audio signal on the cable.

A punchdown tool fixes each conductor into an insulation displacement connector (IDC).

A cable stripper scores the outer jacket just enough to remove it.

A cable tester is a pair of devices designed to attach to each end of a cable. It tests a patch cord or is connected via patch cords to a wall port and patch panel port to test the permanent link.

Sandboxes can be used to analyze viruses, worms, and Trojans. Sandboxes also provide an isolated environment for what other important function?

Testing and development

Test development often uses virtual desktop platforms based on some guest OS hypervisor.

Resource requirements are important to consider and meet when setting up a virtualized system and network for virtualized systems to use. If the system is not designed with resource requirements in mind, it will be overwhelmed and dysfunctional.

Cross-platform utilization tests software applications under different OSs and resource constraints and is important to ensure the application is compatible across several different environments.

Legacy software applications and operating systems may not perform well if a user's system has been upgraded.

A company building is under construction and a technician is getting ready to install communication wires. What can a technician use to make the installation simpler?

Plenum

Plenum is a space that is a void in a building designed to carry heating, ventilation, and air conditioning (HVAC) systems. Plenum space is usually a false ceiling or raised floor.

Straight tip (ST) is a type of core fiber optic connector that is a bayonet-style connector and uses a push-and-twist locking mechanism for mostly multi-mode networks.

A lucent connector (LC) is a type of core fiber optic connector that is a small form factor connector with a tabbed push/pull design. LC is similar to subscriber connector (SC), but the smaller size allows for higher port density.

Fiber cable contains a protective jacket and terminates by a connector. Fiber optic cables fall into two broad categories; single-mode and multi-mode.

What type of printer uses a heating element to create the image on the paper?

Thermal

A thermal printer is a general term for any device that uses a heating element to create paper images. Thermal printers have a heat-sensitive print that the paper is friction-fed through the print mechanism when in the feed assembly.

Laser printers are the most popular printer technologies for office applications because they are inexpensive, quiet, and fast.

What voltage range do appliances such as dryers, heavy-duty power tools, and oven ranges require?

220V

220V is a requirement for appliances because of the high-power range needed to supply them. The power requirement for 200V would be 900 watts of power. This range is typically in commercial applications for large motors and other equipment.

110V is present mainly in portable electronics and small appliances. 110V is typically safer to work with because of the fewer volts.

115V is similar to 110V and rated on a low range that would not support the appliances.

120V is in the same low range as 110V and 115V. 110V, 115V, and 120V have tests to operate at a lower voltage.

A software development company uses a system to allow developers to log into any computer throughout the building and load their unique desktop environment. The IT department decided to manage these servers in the data center located in the basement of the company's office building. What system is the software development company leveraging?

Virtual desktop infrastructure (VDI) on premises

Virtual desktop infrastructure (VDI) on-premises is correct because the developers log into virtual machines that load the users' computer images. The servers are hosted on the same network as the clients.

VDI in the cloud is incorrect because the servers hosting the virtual machines in the cloud mean that the servers are not hosted on the same network as the clients.

Platform as a service (PaaS) is incorrect because PaaS is typically a solution that would deploy hardware and applications platforms for the clients to use.

Infrastructure as a service (IaaS) is incorrect because IaaS is deploying IT hardware through a service provider.

A technician responds to a computer intermittently shutting down and finds that the tower has a personal heater blowing on it. What is a likely problem?

Overheating

The computer is overheating. Even with all the fans working properly, computers cannot have personal space heaters blowing directly on them. Redirecting the heater should resolve the problem.

Intermittent shutdowns can be an indicator of malware, but the physical details in this example do not point to malware as the problem.

A power supply unit (PSU) that is not delivering stable power can cause intermittent shutdowns, but this does not seem to be the problem here. Instead, the space heater is the apparent problem.

Hard drive failure can result in intermittent shutdowns and is diagnosed with OS tools, such as the chkdsk command. However, this is unlikely to be the problem in this case.

Users at an organization prefer that any mobile devices deployed for company use have location services disabled. IT administrators agree and configure which option?

Cat 5 cable supports the older 100 Mbps fast Ethernet standard. It is no longer commercially available, so a technician will need to rewire the network cable with Cat 5 to support Gigabit Ethernet.

CAT 5e

Cat 5e cable supports Gigabit Ethernet links for client computers but can now opt to install Cat 6 cable.

Cat 6

Cat 6 cable is more reliable than Cat 5e and supports 10 Gbps but over reduced range.

A network administrator is looking at a user's box which seems to have intermittent connectivity issues. Which of the following should they do first?

Check the physical cords.

The first step in resolving a no or intermittent connectivity issue is to check that the patch cords are properly terminated and connected to the network ports.

What tool can help diagnose extended read/write times?

SMART

The fixed disk self-diagnostic program called Self-Monitoring, Analysis, and Reporting Technology (SMART) can detect if a drive is close to failure.

This protocol provisions secure websites and services and uses port 443.

HyperText Transfer Protocol Secure

HyperText Transfer Protocol Secure (HTTPS) delivers secure websites and services and uses TCP port 443. Data encrypts over this connection between the client and server.

A user reports that their PC can not access the internet and internal network resources. The user also reports that the internet is intermittent throughout the day. A technician confirmed that the Ethernet cable is connected securely to the PC and the wall port. What tool should an engineer bring with them to investigate this further?

Cable tester

A cable tester is a pair of devices that attach to each end of a cable. It tests a patch cord or connects via patch cords to a wall port and patch panel port to test the permanent link.

A network technician installs wireless access points (APs) in an office and would like to use the power over Ethernet (PoE) features available. The specific model of APs available requires a draw of 20W with a minimum current of 450 mA. Which Institute of Electrical and Electronics Engineers (IEEE) PoE standard best suits this requirement?

802.3at

802.3at (PoE+) allows powered devices to draw up to about

25 W,

with a maximum current of

600 mA.
