The answer is Amazon CloudWatch Container Insights and Amazon CloudWatch. Container Insights is the dedicated service for collecting task-level CPU, memory, and network metrics from ECS Fargate, automatically aggregating performance data from each running task and sending it to CloudWatch. CloudWatch then stores these metrics and provides dashboards for visualization, making it the complete solution for monitoring and troubleshooting. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this pairing tests your understanding of the integrated observability stack for serverless containers—a common trap is choosing CloudWatch Logs for metrics or AWS X-Ray for performance data, but remember that Container Insights is purpose-built for metric collection while CloudWatch handles storage and visualization. A useful memory tip: think of Container Insights as the “collector” and CloudWatch as the “dashboard”—together they give you full task-level visibility without additional configuration.
DOP-C02 Monitoring and Logging Practice Question
This DOP-C02 practice question tests your understanding of monitoring and logging. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is running a microservices application on Amazon ECS with AWS Fargate. The operations team wants to collect and visualize metrics such as CPU, memory, and network utilization at the task level. Which TWO services should the team use to achieve this? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Amazon CloudWatch
Option A (CloudWatch Container Insights) and Option D (Amazon CloudWatch) are correct. Container Insights collects metrics from ECS tasks, and CloudWatch stores and visualizes them via dashboards. Option B (CloudWatch Logs) is for logs, not metrics. Option C (AWS X-Ray) is for tracing. Option E (Amazon Managed Service for Prometheus) can scrape metrics but is not the standard integrated solution for ECS Fargate; Container Insights is the recommended approach.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
