Question 140
A post-change operational risk review considers: A design team needs GPU acceleration for a 3D application delivered through AVD. Which risk MOST DIRECTLY explains the need for the proposed AVD control?
Explanation
Correct Answer
The condition is: A design team needs GPU acceleration for a 3D application delivered through AVD. The directly related risk is: Overcommitting shared RAM or choosing CPU-only hardware for GPU-intensive workloads can damage session responsiveness. The corrective control is: Size session hosts using representative user task concurrency, memory, disk and graphics needs rather than only the number of assigned users. Its test of effectiveness is: A representative load test meets CPU, memory, login and graphics targets at the chosen concurrency. This issue is specific to the observed AVD behavior, not to a separate administration concern.
Incorrect Answers
This option relates to Host pool load-balancing algorithm and max sessions under AZ-140 objective group 1.3. It addresses a different failure risk: A session cap set too low can block capacity and incorrect balancing can concentrate interactive load on undersized hosts. But the observed requirement is: A design team needs GPU acceleration for a 3D application delivered through AVD. For the targeted topic (VM SKU sizing and graphics performance for AVD), the directly relevant risk is: Overcommitting shared RAM or choosing CPU-only hardware for GPU-intensive workloads can damage session responsiveness. 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 Pooled versus personal host pool architecture under AZ-140 objective group 1.3. It addresses a different failure risk: An app requiring persistent machine-specific state may not work as expected when delivered from disposable pooled sessions. But the observed requirement is: A design team needs GPU acceleration for a 3D application delivered through AVD. For the targeted topic (VM SKU sizing and graphics performance for AVD), the directly relevant risk is: Overcommitting shared RAM or choosing CPU-only hardware for GPU-intensive workloads can damage session responsiveness. 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 AVD license entitlement versus Azure consumption under AZ-140 objective group 1.3. It addresses a different failure risk: An Azure subscription with sufficient VM quota does not by itself grant end users every required AVD entitlement. But the observed requirement is: A design team needs GPU acceleration for a 3D application delivered through AVD. For the targeted topic (VM SKU sizing and graphics performance for AVD), the directly relevant risk is: Overcommitting shared RAM or choosing CPU-only hardware for GPU-intensive workloads can damage session responsiveness. 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.
