Microsoft AZ-305 Practice Test 65
Question 640
An event-driven container worker must scale between burst processing and near-zero idle capacity, with a protected queue credential. Which TWO controls are relevant? (Select TWO.)
- Store queue administrator secrets in a public container image.
- Keep a large AKS cluster dedicated to a single intermittent worker without cost review.
- Configure the scaler's authorized identity and queue connection settings.
- Configure Azure Container Apps with a supported event-driven scaler.
- Use a CPU threshold to fix a queue authentication failure.
Explanation
Correct Answers
C:The trigger must authenticate to observe workload backlog.
D:Queue events can drive the number of active worker replicas.
Incorrect Answers
A:Shared static secrets expose the event source.
B:Cluster overhead may be unnecessary.
E:CPU tuning does not grant queue access.
Question 641
An architecture proposal for container apps event-driven scale relies on the following approach: Keep a full AKS cluster solely for one intermittent queue worker without assessing overhead. Which specific failure or mismatch should the design reviewer identify?
- Abrupt rollout broadens blast radius if the new version fails.
- One-off container primitives do not provide a full application rollout controller.
- CPU-based settings cannot fix denied message-source authentication.
- Orchestration management can exceed the simple workload's needs.
Explanation
Correct Answer
D:Keep a full AKS cluster solely for one intermittent queue worker without assessing overhead. Orchestration management can exceed the simple workload's needs.
Incorrect Answers
A:That assessment refers to the separate proposal 'Replace all active replicas at once with no progressive routing.' not to the recommendation under review. Here, Orchestration management can exceed the simple workload's needs.
B:This concern applies to Manually recreate every ACI instance for each release. in another design compute solutions design. The current proposal specifically fails because orchestration management can exceed the simple workload's needs.
C:That assessment refers to the separate proposal 'Increase CPU thresholds instead of verifying queue scaler access.' not to the recommendation under review. Here, Orchestration management can exceed the simple workload's needs.
Question 642
Acceptance testing must establish the following operational result: Observed scaling validates the event signal. Which verification action most directly establishes that outcome?
- Enqueue a test burst and inspect replica creation and idle scale-down.
- Demonstrate rolling updates and automatic service replacement on the target platform.
- Verify a controlled queue event causes a scale rule activation.
- Route a small test percentage to the new revision and observe errors.
Explanation
Correct Answer
A:Observed scaling validates the event signal.
Incorrect Answers
B:This is a test for A company wants stable autoscaling, rolling deployments and service discovery across hundreds of container instances. The requirement here is instead demonstrated by enqueue a test burst and inspect replica creation and idle scale-down.
C:That verification addresses the different requirement: A Container Apps worker fails to scale because its queue authorization is invalid. It does not directly establish observed scaling validates the event signal.
D:That verification addresses the different requirement: A public container service needs controlled revision rollout and traffic splitting between versions. It does not directly establish observed scaling validates the event signal.
Question 643
A public container service needs controlled revision rollout and traffic splitting between versions. Which Azure architecture choice best meets this requirement?
- Replace all active replicas at once with no progressive routing.
- Keep a full AKS cluster solely for one intermittent queue worker without assessing overhead.

- Use Container Apps revisions with configured ingress traffic weights.
Explanation
Correct Answer
D:Revisions enable controlled release validation without external traffic-splitting scripts.
Incorrect Answers
A:Abrupt rollout broadens blast radius if the new version fails. This proposal contradicts the stated architecture constraint.
B:Orchestration management can exceed the simple workload's needs. In the present requirement, a public container service needs controlled revision rollout and traffic splitting between versions. The needed design instead works because revisions enable controlled release validation without external traffic-splitting scripts.
C:CPU-based settings cannot fix denied message-source authentication. In the present requirement, a public container service needs controlled revision rollout and traffic splitting between versions. The needed design instead works because revisions enable controlled release validation without external traffic-splitting scripts.

- Orchestration management can exceed the simple workload's needs.
- Abrupt rollout broadens blast radius if the new version fails.
Explanation
Correct Answer
D:Replace all active replicas at once with no progressive routing. Abrupt rollout broadens blast radius if the new version fails.
Incorrect Answers
A:This concern applies to Run the only production database on Spot with no eviction protection. in another design compute solutions design. The current proposal specifically fails because abrupt rollout broadens blast radius if the new version fails.
B:That assessment refers to the separate proposal 'Increase CPU thresholds instead of verifying queue scaler access.' not to the recommendation under review. Here, Abrupt rollout broadens blast radius if the new version fails.
C:That assessment refers to the separate proposal 'Keep a full AKS cluster solely for one intermittent queue worker without assessing overhead.' not to the recommendation under review. Here, Abrupt rollout broadens blast radius if the new version fails.
Question 645
Acceptance testing must establish the following operational result: Weighted metrics support safe promotion. Which verification action most directly establishes that outcome?
- Route a small test percentage to the new revision and observe errors.
- Model actual 24/7 consumption and pricing commitments.
- Verify a controlled queue event causes a scale rule activation.
- Enqueue a test burst and inspect replica creation and idle scale-down.
Explanation
Correct Answer
A:Weighted metrics support safe promotion.
Incorrect Answers
B:This is a test for A production database needs stable always-on capacity for the next three years. The requirement here is instead demonstrated by route a small test percentage to the new revision and observe errors.
C:That verification addresses the different requirement: A Container Apps worker fails to scale because its queue authorization is invalid. It does not directly establish weighted metrics support safe promotion.
D:That verification addresses the different requirement: A containerized event consumer should scale nearly to zero between queue bursts without managing Kubernetes. It does not directly establish weighted metrics support safe promotion.
Question 646
A Container Apps worker fails to scale because its queue authorization is invalid. Which Azure architecture choice best meets this requirement?
- Increase CPU thresholds instead of verifying queue scaler access.
