GCP Professional Cloud Security Engineer Practice Question

Your company keeps all sales in one BigQuery table, sales.central_facts, which contains a region_code column. Analysts already belong to regional IAM groups such as emea-analysts@corp and apac-analysts@corp. Compliance requires each group to see only the rows for its region. You must meet these rules while keeping a single physical table and avoiding per-region views. What is the lowest-maintenance way to enforce the restriction?

  • Apply Data Catalog policy tags to the region_code column and assign tag-based roles to the regional analyst groups.

  • Create an authorized view per region that filters by region_code and grant each IAM group access to its view.

  • Define row access policies on sales.central_facts that filter on region_code and grant each regional IAM group access to its policy.

  • Partition sales.central_facts on region_code and rely on automatic partition pruning based on the user's identity.
