- A
Use an S3 Gateway Endpoint and ensure the Glue job uses HTTP instead of HTTPS.
Why wrong: HTTP is not encrypted.
- B
Use an S3 Interface Endpoint and disable TLS.
Why wrong: Disabling TLS removes encryption.
- C
Use an S3 Gateway Endpoint and ensure the Glue job uses HTTPS.
Gateway Endpoint forces traffic through AWS network, and HTTPS ensures TLS.
- D
Enable SSE-KMS encryption on both source and destination S3 buckets.
Why wrong: Encryption at rest, not in transit.

DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A company has an AWS Glue ETL job that reads data from an S3 bucket, transforms it, and writes to another S3 bucket. The security team requires that data in transit between the Glue job and S3 be encrypted using TLS. The Glue job runs in a VPC with a VPC endpoint for S3. Which configuration ensures TLS encryption for all data transfer?
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
✓
Use an S3 Gateway Endpoint and ensure the Glue job uses HTTPS.
Option C is correct because an S3 Gateway Endpoint uses HTTPS by default, ensuring TLS encryption for data in transit between the Glue job and S3. Option A is wrong because using HTTP would transmit data unencrypted. Option B is wrong because disabling TLS removes encryption in transit. Option D is wrong because SSE-KMS encrypts data at rest in S3, not in transit.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 |
