DEA-C01 Data Security and Governance Practice Question
A company uses AWS Lake Formation to manage access to data in a data lake. The data engineer needs to grant a user the ability to query tables in the 'sales' database using Amazon Athena, but only when the user's IP address is within the corporate network (10.0.0.0/8). Which combination of actions should the data engineer take?

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
✓
Grant Lake Formation permissions on the tables and attach an IAM policy to the user with aws:SourceIp condition
Lake Formation permissions are needed to grant query access to the tables in the 'sales' database, and an IAM policy attached to the user with a condition key `aws:SourceIp` restricts Athena access to the corporate IP range (10.0.0.0/8). Option A is incorrect because S3 bucket policies with `aws:SourceIp` cannot be used to restrict Athena queries through Lake Formation; Lake Formation manages access at a higher level. Option C is incorrect because using an S3 VPC endpoint alone does not enforce IP-based restrictions; it only restricts network traffic to the VPC. Option D is incorrect because network ACLs operate at the subnet level and do not control access to specific Lake Formation resources or Athena queries.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Grant Lake Formation permissions on the tables and attach an S3 bucket policy with aws:SourceIp condition
Why it's wrong here
S3 bucket policy does not control Athena queries via Lake Formation.
- ✓
Grant Lake Formation permissions on the tables and attach an IAM policy to the user with aws:SourceIp condition
Why this is correct
Correct combination.
- ✗
Use an S3 VPC endpoint and grant Lake Formation permissions on the tables
Why it's wrong here
VPC endpoint does not restrict IP; it restricts network path.
- ✗
Grant Lake Formation permissions on the tables and configure a network ACL in the VPC
Why it's wrong here
NACL does not restrict user-specific access.

| 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 |
