- A
"Condition": {"Bool": {"aws:SecureTransport": "true"}}
This ensures requests are made over HTTPS.
- B
"Condition": {"StringEquals": {"s3:x-amz-server-side-encryption": "AES256"}}
Why wrong: This enforces server-side encryption at rest, not in transit.
- C
"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}
Why wrong: MFA enforces multi-factor authentication, not encryption.
- D
"Condition": {"IpAddress": {"aws:SourceIp": "10.0.0.0/8"}}
Why wrong: IP restriction is not about encryption.

How to Enforce Encryption in Transit for S3 Access from SAP Applications
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 application on AWS needs to access an S3 bucket containing sensitive data. Which IAM policy element should be used to enforce encryption in transit?
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
✓
"Condition": {"Bool": {"aws:SecureTransport": "true"}}
Option A is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing 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.
Detailed technical explanation
How to think about this question
The `aws:SecureTransport` condition key checks whether the `AWS4-HMAC-SHA256` signature or TLS handshake was used; it evaluates to `true` for HTTPS requests and `false` for HTTP. In practice, SAP applications often use the AWS SDK or CLI, which can be configured to enforce HTTPS via endpoint settings (e.g., `https://s3.amazonaws.com`), but the IAM policy acts as a fail-safe to block any accidental HTTP requests. This condition is evaluated at the S3 API level, so even if the client attempts HTTP, the request is denied before any data transfer occurs.
KKey Concepts to Remember
- 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.
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 |
