- A
aws:PrincipalOrgID
Correct. This condition checks the organization ID of the requesting principal, which is an identity attribute.
- B
s3:x-amz-server-side-encryption
Why wrong: Incorrect. This condition is used for encryption settings, not identity-based restrictions.
- C
aws:Referer
Why wrong: Incorrect. This condition checks the HTTP Referer header, which is not a reliable identity attribute.
- D
aws:SourceIp
Why wrong: Incorrect. This condition restricts based on the requester's IP address, which is a network condition, not a direct identity attribute.
- E
aws:userId
Correct. This condition checks the unique ID of the IAM user, directly tied to the requester's identity.

DEA-C01 Identity-based policies Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. 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. A key principle to apply: identity-based policies. 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.
A data engineer needs to ensure that an S3 bucket policy follows the principle of least privilege. Which of the following are valid conditions to restrict access based on the requester's identity? (Choose THREE.)

Correct answer & explanation
✓
aws:PrincipalOrgID
Options A and E are correct. aws:PrincipalOrgID restricts access to IAM principals within a specific AWS Organization, directly tied to the requester's identity. aws:userId restricts access to a specific IAM user ID, also an identity attribute. Option D (aws:SourceIp) is a network condition based on IP address, not the requester's identity, so it does not meet the requirement. Options B (s3:x-amz-server-side-encryption) and C (aws:Referer) are not identity-based conditions.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The phrase 'based on the requester's identity' can be misleading. Network conditions like aws:SourceIp are not considered identity-based; only attributes like user ID, role ID, or organization ID qualify.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

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
Identity-based policies
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 |
