DP-300 Implement a secure environment Practice Question
You have an Azure SQL Database named SalesDB. You need to grant a user named 'ReportingUser' the ability to read all data in the Sales schema but not modify any data. You want to follow the principle of least privilege. What should you do?
⚠ Common exam trap
The trap here is defaulting to built-in roles like db_datareader, which grant access to the entire database rather than a specific schema.
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
✓
Grant SELECT permission on the Sales schema to ReportingUser.
Granting SELECT on the Sales schema directly to ReportingUser provides read-only access to only that schema, adhering to least privilege. The other options grant broader permissions that either include unnecessary access to other schemas or allow data modification, which is not required.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Grant SELECT permission on the Sales schema to ReportingUser.
Why this is correct
Granting SELECT on the Sales schema specifically allows ReportingUser to read all data in that schema while denying access to other schemas. This follows the principle of least privilege by limiting permissions to only what is needed. It is the most precise way to meet the requirement.
- ✗
Add ReportingUser to the db_datareader role.
Why it's wrong here
The db_datareader role grants SELECT permission on all tables and views in the database, not just the Sales schema. This violates the principle of least privilege because ReportingUser would have read access to all schemas, not only Sales. Therefore, it does not meet the requirement.
- ✗
Grant CONTROL permission on the Sales schema to ReportingUser.
Why it's wrong here
CONTROL permission grants full administrative rights on the schema, including the ability to modify data and schema objects. This far exceeds the requirement of read-only access and violates least privilege. It would allow ReportingUser to alter or drop objects, which is not desired.
- ✗
Add ReportingUser to the db_owner role.
Why it's wrong here
The db_owner role grants full control over the entire database, including the ability to modify data, schema, and security settings. This is excessive and does not follow least privilege. It would give ReportingUser far more permissions than needed for read-only access to the Sales schema.
