Question 500
During a cross-team security policy review at Silverline Labs, engineers say that they resolved this finding: A user VPN uses password-only authentication for a sensitive administrative application. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
A valid password without the required second factor cannot open an administrative session. This is the decisive evidence for the original problem: A user VPN uses password-only authentication for a sensitive administrative application. It verifies that the intended corrective control—Integrate supported multifactor authentication and policy assessment into the remote-access workflow—works in the relevant environment; a completed change ticket alone would not prove the outcome at Silverline Labs.
Incorrect Answers
Both peers authenticate with the current key and obsolete credentials fail. This would be relevant evidence for a different failure: A branch site tunnel is configured with an old shared secret after key rotation, usually addressed by Synchronize peer authentication settings using secure credential distribution. It does not demonstrate that the current problem at Silverline Labs was resolved. The specific required evidence is: A valid password without the required second factor cannot open an administrative session.
The VPN negotiates and only the intended subnets carry encrypted packets. This would be relevant evidence for a different failure: Two Cisco Secure Firewall peers cannot establish a site-to-site tunnel because their protected network selectors differ, usually addressed by Align crypto traffic selectors and IKE/IPsec parameters for authorized site prefixes. It does not demonstrate that the current problem at Silverline Labs was resolved. The specific required evidence is: A valid password without the required second factor cannot open an administrative session.
The client reaches its approved application subnet but cannot connect to restricted networks. This would be relevant evidence for a different failure: A remote employee's Cisco Secure Client connects but can access networks outside their assigned group, usually addressed by Apply group policy and authorization with least-privilege split or full-tunnel routing as intended. It does not demonstrate that the current problem at Silverline Labs was resolved. The specific required evidence is: A valid password without the required second factor cannot open an administrative session.
