AWS Certified Data Engineer Associate DEA-C01 Practice Question
Your company stores hundreds of Amazon S3 datasets registered in AWS Glue and governed by Lake Formation. Each table is tagged with an LF-Tag key Project. Engineers assume roles tagged with the same Project value. Security wants a single mechanism that automatically allows SELECT only on tables whose LF-Tag matches the role's Project tag, avoiding per-table grants. Which Lake Formation feature meets this need?
Create an AWS Organizations service control policy that denies Athena actions unless the Project tag matches the caller's tag.
Implement Lake Formation tag-based access control (LF-TBAC) by granting permissions on LF-Tag Project values to engineers and tagging tables with the same values.
Grant SELECT on each table to engineer roles using the named resource method and rely on permission inheritance.
Attach an IAM ABAC policy that compares aws:PrincipalTag/Project to aws:ResourceTag/Project on the Glue catalog and S3 locations.
Lake Formation tag-based access control (LF-TBAC) lets administrators grant permissions on LF-Tags instead of on individual databases or tables. After a principal is granted the LF-Tag value (for example Project=X) and the same LF-Tag is attached to data-catalog resources, Lake Formation automatically authorizes SELECT on every matching table-no additional GRANT statements are required. An IAM ABAC policy cannot enforce table-level authorization for Athena because Glue and Lake Formation control that layer. Named-resource grants would still require explicit updates for every new table, and an AWS Organizations SCP can only allow or deny IAM actions at the account level, not filter Lake Formation resources. Therefore LF-TBAC is the only authorization method that scales while upholding least privilege.
