PDE Designing Data Processing Systems Practice Question
Your team wants to share a BigQuery dataset with another project while ensuring that users from that project can only query specific tables. Which BigQuery feature should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an authorised view in your dataset and share the view with the other project
Authorised views allow you to share query results with users in other projects without giving them direct access to the underlying tables.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create an authorised view in your dataset and share the view with the other project
Why this is correct
Authorised views allow fine-grained access control by sharing only the view's results.
- ✗
Use a materialised view and share the underlying table
Why it's wrong here
Materialised views are for performance, not access control.
- ✗
Grant the BigQuery Data Viewer role to the other project's service account
Why it's wrong here
This grants access to all tables in the dataset, not specific ones.
- ✗
Export the table to Cloud Storage and share the bucket
Why it's wrong here
This creates a copy and does not leverage BigQuery's querying capabilities.
