AWS Certified SysOps Administrator – Associate — Question 110

A company has a workload that is sending log data to Amazon CloudWatch Logs. One of the fields includes a measure of application latency. A SysOps administrator needs to monitor the p90 statistic of this field over time.

What should the SysOps administrator do to meet this requirement?

Answer options

• A. Create an Amazon CloudWatch Contributor Insights rule on the log data.
• B. Create a metric filter on the log data.
• C. Create a subscription filter on the log data.
• D. Create an Amazon CloudWatch Application Insights rule for the workload.

Correct answer: B

Explanation

The correct answer is B, as creating a metric filter allows the SysOps administrator to extract the p90 statistic from the log data and monitor it over time. Options A and D involve rules that are not specifically designed for this statistic, while C’s subscription filter is used for streaming log data rather than monitoring metrics.
