IV. Azure Compute Service

Azure Virtual Machines (VMs)

__________ let you run virtualized servers in Azure as infrastructure as a service (IaaS), where you control the operating system and installed software like a physical server.

Testing and development

Using VMs to create different OS and app configurations quickly, then removing the VM when testing is complete, is the __________ use case.

Cloud application hosting

Running applications in Azure and scaling capacity up or down as demand changes is the __________ use case for VMs.

Datacenter extension

Extending an on-premises network into Azure and hosting workloads in a connected virtual network is the __________ use case for VMs.

Disaster recovery

Keeping failover capacity in Azure and running critical workloads there if your primary site is unavailable is the __________ use case for VMs.

Lift and shift

Moving existing server workloads to Azure with minimal application redesign is called __________ migration.

Processor cores

VM size is determined by its purpose, the number of __________, and the amount of RAM.

Burstable

The Azure VM size family B stands for __________.

General purpose

The Azure VM size family D stands for __________.

Memory (memory optimized)

Compute (compute optimized)

The Azure VM size family F stands for __________.

GPU

The Azure VM size family N stands for __________.

Availability sets

__________ group VMs by update domain and fault domain.

Update domain

A(n) __________ is a group of VMs that can be rebooted together during planned maintenance.

Fault domain

A(n) __________ is a group of VMs that share a potential power or network failure point.

Azure Virtual Desktop

__________ is a desktop and application virtualization service in Azure that lets users securely access Windows desktops and apps from many device types and locations.

Entra ID

In the Azure Virtual Desktop diagram, users on laptop, tablet, or web are authenticated through __________ using access policies.

Host pool

In Azure Virtual Desktop, cloud desktops and apps are delivered from a(n) __________ made up of session hosts.

Session hosts

In Azure Virtual Desktop, a host pool contains multiple __________.

Containers

__________ are a virtualization environment where you can run multiple instances on a single physical or virtual host, and you don't manage the operating system for them.

Operating system

Unlike containers, each virtual machine runs its own __________ that you can connect to and manage.

Lightweight

Containers are __________ and designed to be created, scaled out, and stopped dynamically.

Crash

Containers help you restart quickly after a __________ or hardware interruption.

Docker

One of the most popular container engines, which Azure supports, is __________.

Operating system

With containers, you don't manage the __________ for a container, unlike VMs.

Azure Container Instances (ACI)

__________ offers the fastest and simplest way to run a container in Azure, without managing any virtual machines or adopting extra services.

PaaS (Platform as a Service)

Azure Container Instances are which cloud service model?

Azure Container Apps

__________ are similar to container instances, remove container management overhead, are PaaS, and include built-in load balancing and scaling.

Load balancing and scaling

Azure Container Apps include built-in __________ and __________ so your design can adapt to changing demand.

PaaS

Azure Container Apps are which cloud service model?

Azure Kubernetes Service (AKS)

__________ provides cluster orchestration and fleet lifecycle management for containers, with Kubernetes control.

AKS

Which container option offers the deepest orchestration: ACI, Container Apps, or AKS?

ACI

Which container option offers the fastest start: ACI, Container Apps, or AKS?

Azure Functions

__________ is an event-driven, serverless compute option that doesn't require maintaining virtual machines or containers.

Code

Azure Functions is ideal when you're only concerned about the __________ running your service and not the underlying platform or infrastructure.

Automatically

Azure Functions scale __________ based on demand, making them a good choice when demand is variable.

Automatically deallocated

With Azure Functions, resources are __________ when the function finishes.

CPU time

With Azure Functions, Azure charges you only for the __________ used while your function runs.

Virtual machines

__________ give you maximum control of the hosting environment and may be the most familiar hosting method if you're new to the cloud.

Containers

__________ can isolate and individually manage different aspects of the hosting solution.

You patch and maintain

In application hosting, VMs are described as OS and config control, custom hosting setup, and __________.

Integrated deployment

In application hosting, App Service is described as managed platform, autoscale and HA, and __________.

Azure App Service

__________ lets you build and host web apps, background jobs, mobile back-ends, and RESTful APIs in the programming language of your choice without managing infrastructure.

High availability

Azure App Service offers automatic scaling and __________.

Windows and Linux

App Service supports these two operating systems: __________.

WebJobs

Which App Service type hosts background jobs: Web apps, API apps, WebJobs, or Mobile apps?

API apps

Which App Service type hosts RESTful APIs: Web apps, API apps, WebJobs, or Mobile apps?

Traffic manager

App Service's built-in load balancing and __________ provide high availability.

VMs (Virtual Machines)

Which Azure compute option is IaaS: VMs, Container Instances, Container Apps, or App Service?
