Microsoft Certified: Azure Virtual Desktop Specialty (AZ-140)

C is correct.

Explanation: For a medium workload, premium file shares are recommended. Premium file shares are backed by solid-state drives (SSDs) and must be deployed in the FileStorage storage account type.

A is incorrect: Standard file shares are recommended for light workloads, not medium workloads.

B is incorrect: Standard file shares cannot be deployed in a FileStorage storage account.

D is incorrect: Premium file shares cannot be deployed in a general purpose version 2 (GPv2) storage account.

C is correct.

Explanation: For a Power workload (graphic designers, 3D model makers) with a small user count, the Ultra tier is recommended for Azure NetApp Files.

A is incorrect: The Standard tier is recommended for large user counts in Power workloads, or for Light workloads.

B is incorrect: The Premium tier is recommended for medium user counts in Power workloads.

D is incorrect: Transaction optimized is a performance tier for Azure Files, not Azure NetApp Files.

A is correct.

Explanation: The Azure Virtual Desktop Experience Estimator determines the connection round-trip time (RTT) from a current location, through the Azure Virtual Desktop service, to the Azure region where virtual machines are deployed.

B is incorrect: Connection monitor provides end-to-end connection monitoring for Azure and hybrid endpoints, but the Experience Estimator is the specific tool for estimating AVD RTT from a user location.

C is incorrect: IP flow verify is used to detect traffic filtering issues at a virtual machine level.

D is incorrect: Remote Desktop Diagnostics is an event-based aggregator that marks user or administrator actions as a success or failure.

D is correct.

Explanation: Microsoft recommends deploying no more than 5,000 VMs per Azure subscription per region. To manage environments with more than 5,000 VMs, you should create multiple Azure subscriptions in a hub-spoke architecture and connect them via virtual network peering.

A is incorrect: Deploying 8,000 VMs in a single subscription exceeds the recommended limit of 5,000 VMs per subscription per region.

B is incorrect: Resource groups default to a limit of 800 instances for most resource types, and this does not address the subscription limit.

C is incorrect: Workspace limits do not affect the virtual machine capacity limits of an Azure subscription.

A is correct.

Explanation: QoS policies are not supported for reverse connect transport. You must make sure that RDP Shortpath for managed networks is enabled before implementing DSCP markers on session hosts.

B is incorrect: The TCP-based reverse connect transport does not support QoS policies.

C is incorrect: TURN is used for indirect UDP connections over public networks, whereas QoS requires RDP Shortpath for managed networks.

D is incorrect: RDP Shortpath relies on UDP-based transport; blocking UDP would prevent it from functioning.

B is correct.

Explanation: When creating a private endpoint for initial feed discovery, you should create a separate workspace that is only used for this purpose and doesn't have any application groups registered to it. Deleting this workspace will cause all feed discovery processes to stop working.

A is incorrect: The workspace used for the global sub-resource should not have any application groups registered to it.

C is incorrect: You cannot control access to the workspace used for initial feed discovery; if you configure it to only allow private access, the setting is ignored and it remains accessible from public routes.

D is incorrect: You can only create one private endpoint for the global sub-resource in your entire Azure Virtual Desktop deployment, so you do not create a separate workspace for each host pool.

C is correct.

Explanation: A personal host pool provides each user with their own dedicated VM, and users are typically local administrators who can install or uninstall apps without impacting other users.

A is incorrect: A pooled host pool shares VMs among multiple users, and users typically do not have local administrator rights.

B is incorrect: A pooled host pool shares VMs among multiple users, and users typically do not have local administrator rights.

D is incorrect: A validation host pool is used to test service updates before applying them to a production environment, not to provide dedicated VMs with local admin rights.

B is correct.

Explanation: Depth-first load balancing allows you to saturate a session host with user sessions before directing new connections to the next session host. It requires a maximum session host limit.

A is incorrect: Breadth-first load balancing evenly distributes user sessions across session hosts.

C is incorrect: Persistent is a load balancer type used for personal host pools, not pooled host pools.

D is incorrect: Setting AllowNewConnections to False prevents the load balancer from sending new connections to the session host.

A is correct.

Explanation: You can currently deploy up to 132 VMs in a single ARM template deployment in the Azure Virtual Desktop portal. To create more, you must run the deployment multiple times.

B is incorrect: 400 is the service limit for HostPools per Workspace.

C is incorrect: 500 is the service limit for Application groups per Microsoft Entra tenant.

D is incorrect: 800 is the default limit for instances of most resource types in a resource group.

D is correct.

Explanation: To ensure all parts of the connection (initial feed discovery, feed download, and remote session connections) use private routes, you must deploy one global endpoint for the deployment, one feed endpoint per workspace, and one connection endpoint per host pool.

A is incorrect: This configuration leaves initial feed discovery and feed download on public routes.

B is incorrect: This configuration leaves initial feed discovery on public routes.

C is incorrect: This configuration leaves feed download on public routes.
