Q: 30

HOTSPOT You have an Azure subscription. You plan to deploy an Azure Virtual Desktop solution to the East US Azure region. The solution will contain the resources shown in the following table. You need to recommend a business continuity solution that meets the following requirements: * Users must be able to connect to HostPool1 if a datacenter in the East US region fails. * Costs must be minimized. What should you include in the recommendation for each resource? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Your Answer

Correct Answer:

HOSTPOOL1: AVAILABILITY ZONES

STORAGE1: ZONE-REDUNDANT STORAGE (ZRS)

Explanation

To meet the requirement of surviving a single datacenter failure within the East US region, HostPool1 must use Availability zones. This distributes the session host virtual machines across multiple, physically separate datacenters (zones) within that single region. If one zone fails, the session hosts in the other zones remain operational.

For the solution to function, the user profiles stored in storage1 must also be available. Zone-redundant storage (ZRS) provides the required resilience by synchronously replicating the data across all three availability zones in the primary region. If one datacenter (zone) fails, the profile data is still accessible from the other zones. This combination provides high availability within the region and meets the cost-minimization requirement, as it avoids the higher costs of inter-region replication (like GRS or GZRS).

Section: Redundancy

Content: This documentation, in the context of Azure Files (which storage1 uses for the "Profiles" share), recommends "Standard zone-redundant storage (ZRS)" or "Premium zone-redundant storage (ZRS)" for production environments requiring high availability across availability zones. This confirms ZRS is the correct selection for the profile share's storage account.
