DEA-C01 Data Security and Governance Practice Question
A data engineer is setting up an AWS Glue job that reads from an Amazon Kinesis Data Stream and writes to an Amazon S3 bucket. The security team requires that all data in transit be encrypted using TLS, and that the Glue job must use a VPC endpoint to access Kinesis and S3. Which configuration ensures compliance?
⚠ Common exam trap
The trap here is focusing only on encryption at rest or TLS without ensuring the use of VPC endpoints, which is an explicit requirement in the scenario.
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
✓
Configure the Glue job to use a VPC connection and create VPC endpoints for Kinesis and S3 with policies that enforce TLS.
To meet both TLS encryption in transit and VPC endpoint usage, the Glue job must run within a VPC using a VPC connection, and VPC endpoints for Kinesis and S3 must be created with policies that enforce TLS. This ensures all traffic goes through the endpoints and is encrypted. Other options either address only encryption at rest or do not include VPC endpoints.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Attach a bucket policy to the S3 bucket that denies requests where aws:SecureTransport is false, and enable Kinesis Data Stream encryption in transit.
Why it's wrong here
A bucket policy denying insecure transport enforces TLS for S3, and Kinesis encryption in transit encrypts data to Kinesis, but this does not ensure the Glue job uses VPC endpoints. The requirement explicitly includes using VPC endpoints, which this option does not address.
- ✗
Enable default encryption on the S3 bucket and enable Kinesis Data Stream encryption at rest.
Why it's wrong here
Default encryption on S3 and Kinesis encryption at rest protect data at rest, not in transit. They do not enforce TLS for data moving between the Glue job and these services, nor do they require the use of VPC endpoints.
- ✓
Configure the Glue job to use a VPC connection and create VPC endpoints for Kinesis and S3 with policies that enforce TLS.
Why this is correct
Using a VPC connection for the Glue job and creating VPC endpoints for Kinesis and S3 ensures that traffic goes through the endpoints. Endpoint policies can enforce TLS by denying requests where aws:SecureTransport is false. This meets the requirement for TLS and use of VPC endpoints.
- ✗
Use AWS Glue job bookmarks and enable S3 Transfer Acceleration.
Why it's wrong here
Glue job bookmarks track processed data and do not affect encryption or VPC endpoint usage. S3 Transfer Acceleration speeds up transfers but does not enforce TLS or require VPC endpoints. This option does not meet the security 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 |
