PAS-C01 Operations and Maintenance Practice Question
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 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
✓
Check AWS CloudTrail logs for S3 API call errors
AWS CloudTrail logs record API calls made to Amazon S3, including errors, which can help diagnose why the backup job is failing. Option A is wrong because S3 Transfer Acceleration only improves upload speed, not reliability. Option C is wrong because S3 Lifecycle policies manage object expiration and are unrelated to diagnosing backup failures. Option D is wrong because switching from AWS CLI to SDK does not address the root cause; diagnostics should focus on API call errors, permissions, or network issues.
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.
- ✗
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.
