Question 240
The AVD reviewer evaluates: An image lifecycle policy needs explicit retention and deprecation dates for old versions. Select TWO complementary choices: the recommended response AND the evidence that confirms it worked.
Explanation
Correct Answers
The test concerns: An image lifecycle policy needs explicit retention and deprecation dates for old versions. Decisive evidence is: Deployment records show the approved image version and a previous tested version remains available for rollback. This confirms the intended correction (Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period.) and tests the failure risk: Deploying latest without review can move new session hosts to an untested build and make rollback uncertain. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.
The AVD operational observation is: An image lifecycle policy needs explicit retention and deprecation dates for old versions. The most targeted response is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. This addresses the specific failure mechanism: Deploying latest without review can move new session hosts to an untested build and make rollback uncertain. Verify the outcome by checking: Deployment records show the approved image version and a previous tested version remains available for rollback. The chosen response directly resolves the stated requirement, rather than changing another Azure Virtual Desktop configuration area.
Incorrect Answers
This option relates to OS updates and application compatibility in images under AZ-140 objective group 1.5. It addresses a different failure risk: Publishing patches directly to all production image-based hosts without validation may introduce sign-in or app incompatibility. But the observed requirement is: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant paired response and evidence is: Deployment records show the approved image version and a previous tested version remains available for rollback. 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 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: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant paired response and evidence is: Deployment records show the approved image version and a previous tested version remains available for rollback. 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: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant paired response and evidence is: Deployment records show the approved image version and a previous tested version remains available for rollback. 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.
