Question 360
The AVD reviewer evaluates: A change manager needs canary validation of allow rules before enforcing them on all hosts. Select TWO complementary choices: the recommended response AND the evidence that confirms it worked.
Explanation
Correct Answers
The AVD operational observation is: A change manager needs canary validation of allow rules before enforcing them on all hosts. The most targeted response is: Use supported Windows App Control for Business policies and Controlled Folder Access with tested allow rules to reduce unauthorized executable and data modification risk. This addresses the specific failure mechanism: An untested restrictive allowlist can block legitimate published RemoteApps and profile software after rollout. Verify the outcome by checking: Approved business apps launch and a controlled unauthorized executable or folder-write test is denied as expected. The chosen response directly resolves the stated requirement, rather than changing another Azure Virtual Desktop configuration area.
The test concerns: A change manager needs canary validation of allow rules before enforcing them on all hosts. Decisive evidence is: Approved business apps launch and a controlled unauthorized executable or folder-write test is denied as expected. This confirms the intended correction (Use supported Windows App Control for Business policies and Controlled Folder Access with tested allow rules to reduce unauthorized executable and data modification risk.) and tests the failure risk: An untested restrictive allowlist can block legitimate published RemoteApps and profile software after rollout. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.
Incorrect Answers
This option relates to NSGs, user-defined routes and Azure Firewall controls under AZ-140 objective group 2.2. It addresses a different failure risk: A deny-all outbound policy without exceptions for required AVD control-plane endpoints can cause widespread registration failures. But the observed requirement is: A change manager needs canary validation of allow rules before enforcing them on all hosts. For the targeted topic (App Control for Business and Controlled Folder Access), the directly relevant paired response and evidence is: Approved business apps launch and a controlled unauthorized executable or folder-write test is denied as expected. 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 Trusted Launch and confidential VM protections under AZ-140 objective group 2.2. It addresses a different failure risk: A security flag cannot compensate for an unsupported image generation or size and might stop VM provisioning. But the observed requirement is: A change manager needs canary validation of allow rules before enforcing them on all hosts. For the targeted topic (App Control for Business and Controlled Folder Access), the directly relevant paired response and evidence is: Approved business apps launch and a controlled unauthorized executable or folder-write test is denied as expected. 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 Defender for Cloud security posture for session hosts under AZ-140 objective group 2.2. It addresses a different failure risk: Ignoring cloud security posture alerts can leave exposed management ports or unpatched configurations undetected. But the observed requirement is: A change manager needs canary validation of allow rules before enforcing them on all hosts. For the targeted topic (App Control for Business and Controlled Folder Access), the directly relevant paired response and evidence is: Approved business apps launch and a controlled unauthorized executable or folder-write test is denied as expected. 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.
