CISA Practice Question: Has implemented a role-based access control…
An organization has implemented a role-based access control (RBAC) system. A user complains that they cannot access a file needed to complete a critical task. The file's permission indicates that only the 'Manager' role has read access. The user is assigned to the 'Analyst' role. Which of the following is the BEST course of action?
⚠ Common exam trap
Many exam-takers choose to change file permissions or create a new role (options C or D) because they focus on the immediate technical fix, ignoring the governance and audit requirements that mandate formal change management for any access control modification.

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
✓
Submit a request for temporary access approval via change management
In a properly implemented RBAC system, access changes must follow the principle of least privilege and be formally approved through change management to maintain audit trails and security controls. Granting temporary access via a documented change request ensures that the access is justified, time-bound, and reviewed, preventing unauthorized privilege escalation. This aligns with the CISA domain of Protection of Information Assets, where access control changes must be controlled and monitored.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Assign the user to the Manager role temporarily
Why it's wrong here
This gives the user all Manager privileges, potentially excessive.
- ✓
Submit a request for temporary access approval via change management
Why this is correct
This follows proper authorization and maintains security.
- ✗
Create a new role with only read access to that file
Why it's wrong here
Creating a new role is complex and may not be necessary for a one-time need.
- ✗
Change the file permissions to include Analyst role
Why it's wrong here
This could grant access to all Analysts, maybe not intended.
