Question 340
A post-change operational risk review considers: A subnet NSG rule blocks FSLogix SMB access to a private storage endpoint. Which risk MOST DIRECTLY explains the need for the proposed AVD control?
Explanation
Correct Answer
The condition is: A subnet NSG rule blocks FSLogix SMB access to a private storage endpoint. The directly related risk is: A deny-all outbound policy without exceptions for required AVD control-plane endpoints can cause widespread registration failures. The corrective control is: Design session-host subnet network security groups, user-defined routes and Azure Firewall egress rules using approved AVD endpoint requirements and least privilege. Its test of effectiveness is: Host registration and user connections pass through the scoped allowed paths and unrelated prohibited traffic remains blocked. This issue is specific to the observed AVD behavior, not to a separate administration concern.
Incorrect Answers
This option relates to Defender for Endpoint device onboarding and incident response under AZ-140 objective group 2.2. It addresses a different failure risk: Golden images with incorrect onboarding or duplicate device identity artifacts may create blind spots or duplicate records. But the observed requirement is: A subnet NSG rule blocks FSLogix SMB access to a private storage endpoint. For the targeted topic (NSGs, user-defined routes and Azure Firewall controls), the directly relevant risk is: A deny-all outbound policy without exceptions for required AVD control-plane endpoints can cause widespread registration failures. 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 subnet NSG rule blocks FSLogix SMB access to a private storage endpoint. For the targeted topic (NSGs, user-defined routes and Azure Firewall controls), the directly relevant risk is: A deny-all outbound policy without exceptions for required AVD control-plane endpoints can cause widespread registration failures. 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 subnet NSG rule blocks FSLogix SMB access to a private storage endpoint. For the targeted topic (NSGs, user-defined routes and Azure Firewall controls), the directly relevant risk is: A deny-all outbound policy without exceptions for required AVD control-plane endpoints can cause widespread registration failures. 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.
