Cloud Digital Leader Practice Question: Google Cloud products, services, and solutions
This GCDL practice question tests your understanding of google cloud products, services, and solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses BigQuery for analytics and needs to enforce row-level security based on user department. Only users from the 'Sales' department should see rows where department = 'Sales'. Which BigQuery feature should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Row-level access policies using a filter on the department column
Option B is correct because BigQuery row-level access policies allow filtering rows based on conditions. Option A is wrong because column-level security hides columns, not rows. Option C is wrong because authorized views are for sharing data across projects. Option D is wrong because IAM roles are for access control at the table/dataset level, not row-level.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Custom IAM roles with fine-grained permissions
Why it's wrong here
IAM roles can't filter rows; they grant access at the resource level.
✗
Column-level security with classification tags
Why it's wrong here
Column-level security controls access to columns, not rows.
✗
Authorized views with a WHERE clause
Why it's wrong here
Authorized views are for granting access to a view, but row-level policies are more direct.
✓
Row-level access policies using a filter on the department column
Why this is correct
Row-level access policies restrict which rows users can see based on conditions.

Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
