}Refer to the exhibit. A company applies this SCP to an OU. However, users in the OU are still able to upload objects to S3 without encryption. What is the most likely reason?
⚠ Common exam trap
Many candidates assume denying s3:PutObject without encryption covers all uploads, but they overlook that multipart uploads use the s3:UploadPart action, which is not affected by the s3:PutObject Deny.
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
✓
The users are uploading objects using the Multipart Upload API, which uses the s3:UploadPart action.
The SCP likely denies s3:PutObject unless encryption headers are present, but the Multipart Upload API uses the s3:UploadPart action for uploading individual parts. Since the SCP only denies s3:PutObject without encryption, the s3:UploadPart action is not covered, allowing unencrypted uploads via multipart uploads. This is why users can still upload objects without encryption despite the SCP.
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 users are using SSE-S3 encryption (AES256).
Why it's wrong here
If they use SSE-S3, the header is 'AES256', so it's allowed, but the question says they upload without encryption.
- ✗
The SCP is missing a Deny for s3:PutObject without any encryption header.
Why it's wrong here
The condition denies if encryption is not AES256, which includes no encryption.
- ✗
The users are using SSE-C encryption.
Why it's wrong here
SSE-C encryption does not set the s3:x-amz-server-side-encryption header to 'AES256', so it would be denied.
- ✓
The users are uploading objects using the Multipart Upload API, which uses the s3:UploadPart action.
Why this is correct
The SCP only denies s3:PutObject, not s3:UploadPart.
