Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Remove the previous role's access and assign the new role's access.
Why this is correct
This ensures the user has only the permissions needed for their new role, following least privilege.
- ✗
Keep all access and let the manager manually remove as needed.
Why it's wrong here
This is inefficient and may lead to excessive permissions persisting.
- ✗
Use a single role for all users to simplify management.
Why it's wrong here
This abandons role-based access and likely grants too much or too little permission.
- ✗
Add the new role's access while keeping the previous role's access.
Why it's wrong here
This violates least privilege by retaining unnecessary permissions from the old role.
