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 AWS Lake Formation to grant SELECT permission on the database and tables without granting S3 access
Lake Formation can be used to grant SELECT permission on the database and tables, and by using column-level and row-level filters, but to hide S3 locations, the data scientist should not have direct S3 access. Lake Formation does not require the user to see the S3 path. Granting IAM read-only access to S3 would expose locations. Using a VPC endpoint does not hide locations. Glue resource policies cannot hide S3 locations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a Glue resource policy to restrict access to the database
Why it's wrong here
Glue resource policies can control access to the catalog but do not prevent the user from seeing S3 locations if they have S3 access.
- ✗
Grant the data scientist IAM permissions to access the Glue Data Catalog and the underlying S3 data
Why it's wrong here
This would allow the data scientist to see the S3 locations.
- ✗
Create a VPC endpoint for Glue and S3 to restrict network access
Why it's wrong here
VPC endpoints control network access but do not hide S3 locations from the user.
- ✓
Use AWS Lake Formation to grant SELECT permission on the database and tables without granting S3 access
Why this is correct
Lake Formation can grant access to the Data Catalog and data without giving direct S3 access, and it can hide the S3 locations.
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 |
