- A
Install the Amazon CloudWatch agent on each EC2 instance to collect system metrics and logs, and send them to CloudWatch.
The CloudWatch agent can collect both metrics and logs, replacing Nagios.
- B
Use AWS CloudTrail to monitor instance activity and capture log files.
Why wrong: CloudTrail monitors API calls, not instance-level metrics.
- C
Use AWS Systems Manager Inventory to collect system configuration and log files.
Why wrong: Inventory is for configuration data, not real-time monitoring.
- D
Use AWS Config to track instance configuration changes and trigger alerts.
Why wrong: Config is for configuration compliance, not real-time health monitoring.

DOP-C02 Monitoring and Logging Practice Question
This DOP-C02 practice question tests your understanding of monitoring and logging. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 migrating its on-premises applications to AWS and wants to maintain the same level of monitoring for its Linux-based EC2 instances. They currently use Nagios for monitoring. They want a managed AWS service that can monitor instance health, system metrics, and application logs. Which solution should they use?
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
✓
Install the Amazon CloudWatch agent on each EC2 instance to collect system metrics and logs, and send them to CloudWatch.
Option A is correct because the Amazon CloudWatch agent (unified CloudWatch agent) can collect system metrics (CPU, memory, disk) and logs from EC2 instances and send them to CloudWatch, providing a managed monitoring solution similar to Nagios. Option B is incorrect because AWS CloudTrail is for auditing API calls, not for monitoring system metrics or logs. Option C is incorrect because AWS Systems Manager Inventory collects software inventory and configuration data, not real-time metrics or logs. Option D is incorrect because AWS Config tracks resource configuration changes for compliance, not for monitoring system health.
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 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.
