Why SAP HANA Backup Upload to S3 Fails: Missing s3:PutObjectPart Permission
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 administrator created the above IAM policy for an EC2 instance that performs automated SAP HANA backups. The backup script runs successfully but fails to upload the backup files to the S3 bucket. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The IAM policy does not include permissions for multipart upload operations
The IAM policy shown in the question (not fully displayed here) likely includes s3:PutObject but omits the required s3:PutObjectPart and s3:AbortMultipartUpload permissions. SAP HANA backups often produce large files that exceed the 5 GB single-upload limit, forcing the AWS CLI or SDK to use multipart upload. Without these permissions, the upload fails after the script runs successfully.
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.
✗
The S3 bucket policy denies the upload
Why it's wrong here
There is no evidence of a bucket policy; the IAM policy is insufficient.
✓
The IAM policy does not include permissions for multipart upload operations
Why this is correct
Multipart uploads require additional actions like s3:AbortMultipartUpload.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The IAM policy does not allow s3:PutObject
Why it's wrong here
The policy explicitly allows s3:PutObject.
✗
The EC2 instance does not have permission to create snapshots
Why it's wrong here
The policy allows ec2:CreateSnapshot.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The key trap is that s3:PutObject alone is insufficient for large uploads; candidates mistakenly assume that granting s3:PutObject covers all upload scenarios when multipart upload permissions are also required.
Detailed technical explanation
How to think about this question
Multipart upload is required for objects larger than 5 GB, and the AWS SDK/S3 API automatically initiates it for large files. The IAM policy must explicitly allow s3:PutObjectPart, s3:AbortMultipartUpload, and s3:ListMultipartUploadParts (for resumability) in addition to s3:PutObject. Without these, the upload fails with a 403 error after the initial upload initiation succeeds, which can be misleading because the script appears to start correctly.

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.
TExam Day Tips
→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.
