20+ practice questions focused on Monitoring and Logging — one of the most tested topics on the AWS Certified DevOps Engineer Professional DOP-C02 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Monitoring and Logging PracticeA 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?
Explanation: 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.
A company is using Amazon CloudWatch Synthetics canaries to monitor its web application endpoints. The canaries are deployed in multiple AWS regions. The team wants to aggregate the canary results into a single dashboard in the US East (N. Virginia) region. What is the MOST efficient way to achieve this?
Explanation: CloudWatch cross-region dashboards allow you to aggregate metrics from multiple regions into a single dashboard without data movement. By using metric math, you can reference metric IDs from different regions directly in the dashboard widget, enabling real-time aggregation of Synthetics canary success/failure rates and latency metrics from all regions into a unified view in US East (N. Virginia). This approach avoids unnecessary data replication, reduces latency, and minimizes operational overhead.
A DevOps team is troubleshooting a slow application. They enabled AWS X-Ray tracing and see that one of the downstream services has a high average response time. However, the traces show that the service itself is fast; the delay is in the network call from the upstream service. Which X-Ray feature should the team use to identify the root cause?
Explanation: The trace map in AWS X-Ray provides a visual representation of the service graph, showing the connections and latency between services. Since the delay is in the network call from the upstream service to the downstream service, the trace map can highlight the specific edge where the high latency occurs, allowing the team to pinpoint whether the issue is due to network congestion, DNS resolution, or a slow HTTP connection. This is the most direct way to identify the root cause of the inter-service communication delay.
A company needs to monitor the CPU utilization of its Amazon RDS for PostgreSQL instance. The metric should be available in Amazon CloudWatch with a granularity of 1 minute. Which action should the team take?
Explanation: Amazon RDS for PostgreSQL automatically publishes metrics, including CPU utilization, to CloudWatch with a default granularity of 1 minute for standard instances. No additional configuration is required to enable this basic monitoring. The metrics are collected by the RDS hypervisor layer and sent to CloudWatch without needing an agent or extra setup.
A company runs a containerized application on Amazon ECS Fargate. The DevOps team wants to collect custom application metrics (e.g., request count, error rate) and send them to Amazon CloudWatch. The team wants to minimize changes to the application code. Which solution should be used?
Explanation: The CloudWatch agent can run as a sidecar container in the same ECS task definition and listen for StatsD metrics (over UDP port 8125) from the application container. This approach requires zero changes to the application code—the application simply emits StatsD-formatted metrics, and the CloudWatch agent forwards them to CloudWatch via the PutMetricData API. It minimizes operational overhead while enabling custom metric collection from containerized workloads on Fargate.

Practice all Monitoring and Logging questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Monitoring and Logging. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Monitoring and Logging questions on the DOP-C02 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Monitoring and Logging is tested as part of the AWS Certified DevOps Engineer Professional DOP-C02 blueprint. Practicing with targeted Monitoring and Logging questions ensures you can handle any format or difficulty that appears.
