Google Cloud Professional Cloud Developer — Question 6

Your company has a BigQuery dataset named "Master" that keeps information about employee travel and expenses. This information is organized by employee department. That means employees should only be able to view information for their department. You want to apply a security framework to enforce this requirement with the minimum number of steps.
What should you do?

Answer options

• A. Create a separate dataset for each department. Create a view with an appropriate WHERE clause to select records from a particular dataset for the specific department. Authorize this view to access records from your Master dataset. Give employees the permission to this department-specific dataset.
• B. Create a separate dataset for each department. Create a data pipeline for each department to copy appropriate information from the Master dataset to the specific dataset for the department. Give employees the permission to this department-specific dataset.
• C. Create a dataset named Master dataset. Create a separate view for each department in the Master dataset. Give employees access to the specific view for their department.
• D. Create a dataset named Master dataset. Create a separate table for each department in the Master dataset. Give employees access to the specific table for their department.

Correct answer: C

Explanation

The correct answer is C because creating separate views for each department within the Master dataset allows for secure access control with minimal effort. Options A and B unnecessarily complicate the setup by creating multiple datasets or requiring data duplication, which is not efficient. Option D also complicates data management by creating multiple tables instead of utilizing views.
