PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP administrator notices that the SAP HANA database backups to Amazon S3 are failing intermittently with timeout errors. The backup script uses the AWS CLI to copy files to an S3 bucket. What is the most likely cause and solution?
⚠ Common exam trap
It's easy for candidates to assume S3 Transfer Acceleration is the solution for any slow or failing upload, but the question specifically mentions intermittent timeout errors with large files, which points to multipart upload and timeout configuration rather than acceleration.

Correct answer & explanation
✓
The backup files are large and the CLI command does not use multipart upload; use multipart upload and increase timeout values
The intermittent timeout errors when copying large SAP HANA backup files to Amazon S3 via the AWS CLI are most likely caused by the CLI not using multipart upload for large files. The AWS CLI automatically uses multipart upload for files over a certain threshold (default 8 MB), but if the upload is timing out, the default timeout values may be insufficient for very large files. Enabling multipart upload and increasing the `--cli-read-timeout` and `--cli-connect-timeout` values resolves the issue by splitting the file into smaller parts and allowing more time for each part to complete.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The S3 bucket policy is too restrictive, modify the policy
Why it's wrong here
Policy issues cause access denied, not timeouts.
- ✗
The S3 bucket has a lifecycle policy that deletes objects too quickly
Why it's wrong here
Lifecycle policies do not cause upload timeouts.
- ✓
The backup files are large and the CLI command does not use multipart upload; use multipart upload and increase timeout values
Why this is correct
Large files need multipart upload and appropriate timeouts.
- ✗
S3 Transfer Acceleration is not enabled, enable it
Why it's wrong here
Transfer Acceleration improves speed but does not prevent timeouts.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
