Question 287 of 1,511
DOP-C02 Monitoring and Logging Practice Question
A company wants to monitor the number of messages in an Amazon SQS queue and send an alert if the queue depth exceeds 1000 for more than 5 minutes. Which AWS service should be used to create the alarm?
⚠ Common exam trap
Many exam-takers confuse EventBridge's ability to react to SQS metric changes (via CloudWatch metric streams) with the actual alarm evaluation logic, but EventBridge cannot perform threshold-based monitoring over a time window—only CloudWatch Alarms can.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudWatch Alarms
Amazon CloudWatch Alarms is the correct service because it can monitor SQS queue metrics (such as ApproximateNumberOfMessagesVisible) and trigger an alarm when the metric exceeds a threshold (e.g., 1000) for a specified evaluation period (e.g., 5 minutes). CloudWatch Alarms directly integrate with SQS via the AWS/SQS namespace and support actions like sending notifications through Amazon SNS.
