SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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.
Refer to the exhibit. A security engineer finds this S3 bucket policy on a bucket that should be private. What is the most effective way to detect if this bucket was accessed by unauthorized users?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Query AWS CloudTrail for GetObject API calls.
CloudTrail logs S3 API calls, including GetObject, and can be used to identify who accessed the bucket. Option A is wrong because S3 server access logs are not enabled by default. Option B is wrong because VPC Flow Logs do not capture S3 API calls. Option C is wrong because CloudWatch Logs does not capture S3 API calls directly.
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.
✗
Enable S3 server access logs on the bucket.
Why it's wrong here
Server access logs need to be enabled first; they are not historic.
✓
Query AWS CloudTrail for GetObject API calls.
Why this is correct
CloudTrail logs all S3 API calls, including GetObject, and can be queried.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use CloudWatch Logs to search for GetObject events.
Why it's wrong here
CloudWatch Logs does not contain S3 API calls unless configured.
✗
Analyze VPC Flow Logs for traffic to the bucket.
Why it's wrong here
VPC Flow Logs capture network traffic, not S3 API calls.
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 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.
