Question 220
A post-change operational risk review considers: A host deployment fails because its target region lacks the required custom image replica. Which risk MOST DIRECTLY explains the need for the proposed AVD control?
Explanation
Correct Answer
The condition is: A host deployment fails because its target region lacks the required custom image replica. The directly related risk is: A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere. The corrective control is: Publish versioned images through Azure Compute Gallery with suitable regional replication and access permissions for deployment locations. Its test of effectiveness is: New hosts in each approved region can select the intended image version without manual file copying. This issue is specific to the observed AVD behavior, not to a separate administration concern.
Incorrect Answers
This option relates to Image rollout canary and rollback strategy under AZ-140 objective group 1.5. It addresses a different failure risk: Replacing every production host with an untested image can spread authentication, app or agent failures simultaneously. But the observed requirement is: A host deployment fails because its target region lacks the required custom image replica. For the targeted topic (Azure Compute Gallery image distribution), the directly relevant risk is: A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
This option relates to Custom image VM generation and compatibility under AZ-140 objective group 1.5. It addresses a different failure risk: A V2 image deployed on an incompatible VM generation or unsupported OS may fail provisioning even when gallery permissions are correct. But the observed requirement is: A host deployment fails because its target region lacks the required custom image replica. For the targeted topic (Azure Compute Gallery image distribution), the directly relevant risk is: A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
This option relates to Azure VM Image Builder repeatable image creation under AZ-140 objective group 1.5. It addresses a different failure risk: Manually updating a single golden VM offers poor auditability and inconsistent package versions across image releases. But the observed requirement is: A host deployment fails because its target region lacks the required custom image replica. For the targeted topic (Azure Compute Gallery image distribution), the directly relevant risk is: A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
