This CC practice question tests your understanding of security principles. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company has implemented a role-based access control (RBAC) system. A new employee in the finance department is granted the 'Finance User' role, which allows them to view invoices but not create payments. However, after a system upgrade, it is discovered that the 'Finance User' role now includes the ability to create payments due to a misconfiguration. The employee did not request this additional privilege and has not exploited it. The security team is notified. Which principle has been violated, and what is the most appropriate immediate action?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Least privilege; correct the role permissions to only what is necessary
Correct: Least privilege is violated because the employee has more permissions than needed. The immediate action is to correct the role permissions and revert the misconfiguration (C). Option A is wrong because the employee did not misuse the privilege; Option B is wrong because disabling the account prevents work; Option D is wrong because removing the role altogether is too broad.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Separation of duties; disable the employee's account until an investigation is complete
Why it's wrong here
Disabling the account is unnecessary and harsh since the employee did not misuse.
✗
Accountability; remove the 'Finance User' role from all employees
Why it's wrong here
Removing the role from everyone is excessive and disrupts operations.
✗
Least privilege; revoke the employee's access permanently
Why it's wrong here
The employee is not at fault; revoking access would disrupt their work.
✓
Least privilege; correct the role permissions to only what is necessary
Why this is correct
This restores the principle without impacting the employee's legitimate duties.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
