Question 710
A warehouse application sometimes times out and engineers guess which database operation is expensive. The developer recommends the following change: Use timing and performance telemetry to locate the measured slow operation before optimizing. Which technical explanation most directly justifies it in this case?
Explanation
Correct Answer
Performance work should target observed long-running calls rather than speculative components. It connects the proposed action to the exact failure or requirement—A warehouse application sometimes times out and engineers guess which database operation is expensive. Confirmation would be instrumented measurements identify a slow code path and show reduced duration after a controlled fix.
Incorrect Answers
That mechanism explains why the alternative action—enable and verify environment-level telemetry to the intended application insights resource—helps in another case. It does not justify the proposed fix here; performance work should target observed long-running calls rather than speculative components. The distinguishing requirement is: A warehouse application sometimes times out and engineers guess which database operation is expensive.
That mechanism explains why the alternative action—configure supported app-level application insights telemetry for the extension—helps in another case. It does not justify the proposed fix here; performance work should target observed long-running calls rather than speculative components. The distinguishing requirement is: A warehouse application sometimes times out and engineers guess which database operation is expensive.
That mechanism explains why the alternative action—emit purposeful custom feature telemetry such as usage, uptake and error signals—helps in another case. It does not justify the proposed fix here; performance work should target observed long-running calls rather than speculative components. The distinguishing requirement is: A warehouse application sometimes times out and engineers guess which database operation is expensive.
