PAS-C01 Design of SAP Workloads on AWS Practice Question
An SAP application on AWS needs to access an S3 bucket containing sensitive data. Which IAM policy element should be used to enforce encryption in transit?
⚠ Common exam trap
Watch out — candidates often confuse encryption in transit (HTTPS/TLS) with encryption at rest (server-side encryption), leading candidates to select Option B, which addresses data encryption on disk, not during network transfer.

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
✓
"Condition": {"Bool": {"aws:SecureTransport": "true"}}
The `aws:SecureTransport` condition key in an IAM policy enforces that all requests to the S3 bucket must be made over HTTPS (TLS), ensuring encryption in transit. For an SAP application handling sensitive data, this prevents data exposure during transmission over the network. The `Bool` condition evaluates to `true` only when the request uses SSL/TLS.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
"Condition": {"Bool": {"aws:SecureTransport": "true"}}
Why this is correct
This ensures requests are made over HTTPS.
- ✗
"Condition": {"StringEquals": {"s3:x-amz-server-side-encryption": "AES256"}}
Why it's wrong here
This enforces server-side encryption at rest, not in transit.
- ✗
"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}
Why it's wrong here
MFA enforces multi-factor authentication, not encryption.
- ✗
"Condition": {"IpAddress": {"aws:SourceIp": "10.0.0.0/8"}}
Why it's wrong here
IP restriction is not about encryption.
Quick reference
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 |
