The answer is to check AWS CloudTrail logs for S3 API call errors. This is the correct diagnostic step because intermittent backup failures often stem from transient permission issues, throttling, or network errors that are recorded as S3 API calls in CloudTrail, whereas the backup script itself may not surface the root cause. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your ability to differentiate between operational monitoring and configuration fixes—a common trap is jumping to enable S3 Transfer Acceleration or adjust lifecycle policies, which do not address intermittent API-level failures. Remember that CloudTrail is your forensic record for any S3 operation, making it the first place to look when a script works sometimes but fails unpredictably. Memory tip: “When backups are flaky, check the trail, not the pail.”
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An SAP system administrator notices that the SAP HANA database backup job to Amazon S3 is failing intermittently. The backup script uses the AWS CLI. Which step should be taken to diagnose the issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check AWS CloudTrail logs for S3 API call errors
Option A is correct because checking CloudTrail logs reveals API call errors. Option B is wrong as S3 Transfer Acceleration would not fix failures. Option C is wrong because the script already uses CLI. Option D is wrong because lifecycle policies don't affect backup jobs.
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 Transfer Acceleration on the bucket
Why it's wrong here
This improves speed but doesn't fix intermittent failures.
✓
Check AWS CloudTrail logs for S3 API call errors
Why this is correct
CloudTrail logs show failed API calls and error codes.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure S3 Lifecycle policy to expire incomplete multipart uploads
Why it's wrong here
Does not address the backup job failures.
✗
Modify the backup script to use the AWS SDK instead of CLI
Why it's wrong here
Not likely to resolve intermittent failures.
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.
