Microsoft AZ-305 Practice Test 68
Question 670
A rendering farm must save costs by using preemptible capacity but tolerate interruptions. Which Azure architecture choice best meets this requirement?
- Run every independent simulation sequentially on one small VM.
- Assume interrupted tasks always preserve all local scratch files and cannot be restarted.
- Increment a billing total every time the same task starts.
- Design retryable Batch tasks on eligible low-priority or Spot nodes.
Explanation
Correct Answer
D:Interruptible compute can lower cost when tasks checkpoint or retry safely.
Incorrect Answers
A:Sequential processing can miss the required throughput window. In the present requirement, a rendering farm must save costs by using preemptible capacity but tolerate interruptions. The needed design instead works because interruptible compute can lower cost when tasks checkpoint or retry safely.
B:Spot eviction may destroy unpersisted local state. This proposal contradicts the stated architecture constraint.
C:A retried task can double-count business results. In the present requirement, a rendering farm must save costs by using preemptible capacity but tolerate interruptions. The needed design instead works because interruptible compute can lower cost when tasks checkpoint or retry safely.
Question 671
An architecture proposal for azure batch large compute jobs relies on the following approach: Assume interrupted tasks always preserve all local scratch files and cannot be restarted. Which specific failure or mismatch should the design reviewer identify?
- Sequential processing can miss the required throughput window.
- Spot eviction may destroy unpersisted local state.
- Eviction risks violate the steady mission-critical capacity requirement.
- A retried task can double-count business results.
Explanation
Correct Answer
B:Assume interrupted tasks always preserve all local scratch files and cannot be restarted. Spot eviction may destroy unpersisted local state.
Incorrect Answers
A:That assessment refers to the separate proposal 'Run every independent simulation sequentially on one small VM.' not to the recommendation under review. Here, Spot eviction may destroy unpersisted local state.
C: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 spot eviction may destroy unpersisted local state.
D:That assessment refers to the separate proposal 'Increment a billing total every time the same task starts.' not to the recommendation under review. Here, Spot eviction may destroy unpersisted local state.
Question 672
Acceptance testing must establish the following operational result: Recoverable execution validates cost-saving preemption. Which verification action most directly establishes that outcome?
- Kill a test worker midtask and compare final output hashes.
- Force task retry and compare committed output integrity.
- Measure parallel task completion and node allocation for a sample workload.
- Model actual 24/7 consumption and pricing commitments.
Explanation
Correct Answer
B:Recoverable execution validates cost-saving preemption.
Incorrect Answers
A:That verification addresses the different requirement: A nightly Batch pipeline produces duplicate output when a worker is retried. It does not directly establish recoverable execution validates cost-saving preemption.
C:That verification addresses the different requirement: A research team runs ten thousand independent simulation tasks once a week on ephemeral nodes. It does not directly establish recoverable execution validates cost-saving preemption.
D: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 force task retry and compare committed output integrity.
Question 673
A nightly Batch pipeline produces duplicate output when a worker is retried. Which Azure architecture choice best meets this requirement?
- Run every independent simulation sequentially on one small VM.
- Assume interrupted tasks always preserve all local scratch files and cannot be restarted.
- Increment a billing total every time the same task starts.
- Make tasks idempotent with uniquely keyed durable outputs and completion markers.
Explanation
Correct Answer
D:Batch retry semantics require protection against replay side effects.
Incorrect Answers
A:Sequential processing can miss the required throughput window. In the present requirement, a nightly Batch pipeline produces duplicate output when a worker is retried. The needed design instead works because batch retry semantics require protection against replay side effects.
B:Spot eviction may destroy unpersisted local state. In the present requirement, a nightly Batch pipeline produces duplicate output when a worker is retried. The needed design instead works because batch retry semantics require protection against replay side effects.
C:A retried task can double-count business results. This proposal contradicts the stated architecture constraint.
Question 674
An architecture proposal for azure batch large compute jobs relies on the following approach: Increment a billing total every time the same task starts. Which specific failure or mismatch should the design reviewer identify?
- A retried task can double-count business results.
- Spot eviction may destroy unpersisted local state.
- A zonal outage could remove the whole fleet.
- Sequential processing can miss the required throughput window.
Explanation
Correct Answer
A:Increment a billing total every time the same task starts. A retried task can double-count business results.
Incorrect Answers
B:That assessment refers to the separate proposal 'Assume interrupted tasks always preserve all local scratch files and cannot be restarted.' not to the recommendation under review. Here, A retried task can double-count business results.
C:This concern applies to Put every scale set instance in one zone and claim regional zone resilience. in another design compute solutions design. The current proposal specifically fails because a retried task can double-count business results.
D:That assessment refers to the separate proposal 'Run every independent simulation sequentially on one small VM.' not to the recommendation under review. Here, A retried task can double-count business results.
Question 675
Acceptance testing must establish the following operational result: Output equality demonstrates safe retry behavior. Which verification action most directly establishes that outcome?
- Kill a test worker midtask and compare final output hashes.
- Force task retry and compare committed output integrity.
- Simulate loss of an instance group in one zone and inspect serving capacity.
- Measure parallel task completion and node allocation for a sample workload.
Explanation
Correct Answer
A:Output equality demonstrates safe retry behavior.
Incorrect Answers
B:That verification addresses the different requirement: A rendering farm must save costs by using preemptible capacity but tolerate interruptions. It does not directly establish output equality demonstrates safe retry behavior.
C:This is a test for An availability-critical VMSS must spread instances among multiple availability zones. The requirement here is instead demonstrated by kill a test worker midtask and compare final output hashes.
D:That verification addresses the different requirement: A research team runs ten thousand independent simulation tasks once a week on ephemeral nodes. It does not directly establish output equality demonstrates safe retry behavior.
Question 676
A production database needs stable always-on capacity for the next three years. Which Azure architecture choice best meets this requirement?
- Purchase permanent largest-size VMs without considering idle hours.
- Compare reserved capacity or savings commitments against on-demand VM economics.
- Run the only production database on Spot with no eviction protection.
- Treat Spot allocation as a guaranteed reserved production SLA.
Explanation
Correct Answer
B:Predictable usage may justify commitment discounts with adequate flexibility review.
Incorrect Answers
A:Idle oversizing wastes operating budget. In the present requirement, a production database needs stable always-on capacity for the next three years. The needed design instead works because predictable usage may justify commitment discounts with adequate flexibility review.
C:Eviction risks violate the steady mission-critical capacity requirement. This proposal contradicts the stated architecture constraint.
