AWS Certified SysOps Administrator – Associate (legacy) — Question 609

In the context of sending metrics to CloudWatch using Amazon Kinesis, which of the following statements best describes the metric "PutRecord.Latency"?

Answer options

• A. It is the time taken per PutRecord operation, measured over the specified time period.
• B. It is the number of successful records in a PutRecords operation per Amazon Kinesis stream, measured over the specified time period.
• C. It is the time taken per PutRecords operation to calculate the statistics of the PutRecords opera-tions.
• D. It is the number of successful PutRecord operations per Amazon Kinesis stream, measured over the specified time period.

Correct answer: A

Explanation

The "PutRecord.Latency" metric in Amazon CloudWatch measures the execution time for each individual PutRecord call over a specified time interval, making Option A the correct description. Options B and D describe count-based metrics rather than latency, which is a measure of time. Option C is incorrect because it refers to PutRecords (plural) and focuses on statistical calculation rather than the actual operation duration.
