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 uses Amazon CloudWatch Logs to store application logs from multiple EC2 instances. The security team requires that logs be encrypted at rest using a customer-managed KMS key. Which configuration step should the engineer perform to meet this requirement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Associate the KMS key with the CloudWatch log group using the console or CLI
Option C is correct because you must associate a KMS key with the log group to encrypt logs. Option A is wrong because the CloudWatch Agent does not handle encryption at rest. Option B is wrong because KMS key policy alone is insufficient; you must specify the key. Option D is wrong because S3 encryption does not apply to CloudWatch Logs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Configure the CloudWatch agent to encrypt logs before sending
Create a KMS key and attach a policy allowing CloudWatch Logs to use it
Why it's wrong here
A policy is needed but you must also associate the key with the log group.
✗
Enable default encryption on the S3 bucket that stores logs
Why it's wrong here
CloudWatch Logs does not store logs in S3 by default.
✓
Associate the KMS key with the CloudWatch log group using the console or CLI
Why this is correct
Associating the KMS key encrypts the log group at rest.

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.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
