Quick Answer
The answer is Amazon CloudWatch Dashboards, because it is the native AWS service designed to visualize operational metrics from EC2 instances, including CPU utilization, memory usage, and disk I/O. While EC2 automatically publishes CPU metrics, memory and disk metrics require the CloudWatch agent to be installed on the instance to collect and send them to CloudWatch, where Dashboards can then display all three in a single pane. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of the CloudWatch agent’s role in extending default EC2 monitoring—a common trap is confusing CloudWatch Dashboards with QuickSight (business intelligence) or Systems Manager (operational management). Remember that CloudWatch Dashboards are for real-time infrastructure monitoring, not analytics or auditing. A helpful memory tip: “Dashboards display, agents acquire”—the CloudWatch agent acquires memory and disk data so Dashboards can display it.
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 wants to visualize the performance of their application running on EC2. They need to create a dashboard that shows CPU utilization, memory usage, and disk I/O. Which AWS service should they use?
Amazon CloudWatch Dashboards.
CloudWatch Dashboards can display custom metrics from the CloudWatch agent.
AWS CloudTrail.
Why wrong: CloudTrail is for auditing API calls.
AWS Systems Manager.
Why wrong: Systems Manager is for operational management, not dashboards.
Amazon QuickSight.
Why wrong: QuickSight is for BI, not real-time infrastructure monitoring.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon CloudWatch Dashboards.
Option A is correct because CloudWatch Dashboards can display metrics from EC2 and the CloudWatch agent, including memory and disk metrics. Option B is wrong because QuickSight is for business intelligence, not infrastructure monitoring. Option C is wrong because Systems Manager is for management, not visualization. Option D is wrong because CloudTrail is for auditing API calls.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
