Answer-first summary for fast verification
Answer: Select a latency metric for a request-based method of evaluation.
To verify that requests to the service will be addressed in fewer than 300 ms at least 90% of the time per calendar month, you should focus on latency, not availability, because the requirement is about response time. Therefore, options C and D, which focus on availability, are incorrect. Between the remaining options, a request-based method of evaluation (option A) is more appropriate than a window-based method (option B) because the requirement is specified in terms of the percentage of requests that meet the latency threshold, not the percentage of time the service meets the latency threshold. Thus, the correct answer is to select a latency metric for a request-based method of evaluation.
