Question 530
The acceptance test asks: A pooled host shows acceptable CPU but users experience severe memory paging in peak hour. Which observation MOST DIRECTLY verifies the appropriate corrective approach succeeded?
Explanation
Correct Answer
The test concerns: A pooled host shows acceptable CPU but users experience severe memory paging in peak hour. Decisive evidence is: Controlled concurrency testing meets documented UX targets at the proposed host density and VM SKU. This confirms the intended correction (Correlate active session density, CPU, RAM, disk latency, GPU use and user experience before adjusting host sizes and capacity thresholds.) and tests the failure risk: Sizing from average CPU alone can hide per-user RAM exhaustion or profile storage bottlenecks. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.
Incorrect Answers
This option relates to Azure Monitor Insights workbooks and connection metrics under AZ-140 objective group 4.1. It addresses a different failure risk: A healthy Azure VM power state does not prove the end-user connection and interactive session are healthy. But the observed requirement is: A pooled host shows acceptable CPU but users experience severe memory paging in peak hour. For the targeted topic (Session host capacity and resource optimization), the directly relevant verification is: Controlled concurrency testing meets documented UX targets at the proposed host density and VM SKU. 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 Personal host pool autoscale and Start VM on Connect under AZ-140 objective group 4.1. It addresses a different failure risk: Applying pooled load-balancing assumptions to personal host pools can stop the wrong dedicated VM or prevent users from restarting it. But the observed requirement is: A pooled host shows acceptable CPU but users experience severe memory paging in peak hour. For the targeted topic (Session host capacity and resource optimization), the directly relevant verification is: Controlled concurrency testing meets documented UX targets at the proposed host density and VM SKU. 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 Virtual Desktop diagnostic settings to Log Analytics under AZ-140 objective group 4.1. It addresses a different failure risk: Without diagnostics enabled on the appropriate resource, historical connections and registration errors may not be available for investigation. But the observed requirement is: A pooled host shows acceptable CPU but users experience severe memory paging in peak hour. For the targeted topic (Session host capacity and resource optimization), the directly relevant verification is: Controlled concurrency testing meets documented UX targets at the proposed host density and VM SKU. 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.
