Question 500
An administrator schedules a Data Collector Set that runs under an account lacking access to required counters and reports an empty log. Which observed result BEST demonstrates that the intended outcome has been achieved?
Explanation
Correct Answer
Time-series evidence isolates the constrained resource and shows whether a tested change improves application throughput without creating another bottleneck. This is an observable acceptance condition, not merely evidence that a feature was enabled. A single instantaneous CPU percentage does not prove the cause of slow application response; performance diagnosis needs aligned counters and load context. Situation: An administrator schedules a Data Collector Set that runs under an account lacking access to required counters and reports an empty log.
Incorrect Answers
The expected hostname resolves to the approved address and connectivity to required service ports is verified from affected and unaffected locations. This tests Windows DNS and network connectivity troubleshooting, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Time-series evidence isolates the constrained resource and shows whether a tested change improves application throughput without creating another bottleneck. Situation: An administrator schedules a Data Collector Set that runs under an account lacking access to required counters and reports an empty log.
The affected server boots or extension provisions with required services verified, and the original failure has a documented cause and safe rollback. This tests Boot, storage and Azure Arc extension failures, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Time-series evidence isolates the constrained resource and shows whether a tested change improves application throughput without creating another bottleneck. Situation: An administrator schedules a Data Collector Set that runs under an account lacking access to required counters and reports an empty log.
The required counters and events arrive with source identity and delay within the expected interval, and actionable thresholds notify the responsible team. This tests Azure Monitor data collection rules and VM Insights, but does not demonstrate that the requested outcome is satisfied. The relevant acceptance test is: Time-series evidence isolates the constrained resource and shows whether a tested change improves application throughput without creating another bottleneck. Situation: An administrator schedules a Data Collector Set that runs under an account lacking access to required counters and reports an empty log.
