DEA-C01 Data Ingestion and Transformation Practice Question
A company is using AWS Lake Formation to manage permissions on data in Amazon S3. They need to ingest data from an external source into a new database 'sales_db' and a table 'transactions' using AWS Glue. The IAM role used by Glue must have the minimal permissions to create the database and table in the Data Catalog and write data to the S3 location. Which combination of permissions should be granted?

Correct answer & explanation
✓
Lake Formation permissions: `CREATE_DATABASE` on the catalog, `CREATE_TABLE` on `sales_db`, and S3 location permission
AWS Lake Formation manages permissions on the Data Catalog. To create a database and table, the Glue IAM role must have Lake Formation `CREATE_DATABASE` on the catalog and `CREATE_TABLE` on the `sales_db` database. Additionally, to write data to the S3 location, the role needs S3 write permissions (either via an IAM policy or Lake Formation data location permissions). Option A lacks Lake Formation permissions. Option B grants overly broad `lakeformation:GrantPermissions` which is not needed for creation. Option C provides only S3 permissions, missing Data Catalog permissions. Thus, D is the minimal combination.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
IAM policy with `glue:CreateDatabase`, `glue:CreateTable`, and `s3:PutObject`
Why it's wrong here
Missing Lake Formation permissions; Glue will fail.
- ✗
IAM policy with `lakeformation:GrantPermissions` on the database and table
Why it's wrong here
GrantPermissions is for granting to others, not for creating.
- ✗
IAM policy with `s3:GetObject` and `s3:PutObject` on the target location
Why it's wrong here
Missing Data Catalog permissions.
- ✓
Lake Formation permissions: `CREATE_DATABASE` on the catalog, `CREATE_TABLE` on `sales_db`, and S3 location permission
Why this is correct
Lake Formation controls Data Catalog operations; S3 write is also needed.
