Question 440
During a scheduled security controls review at Aster Mutual, engineers say that they resolved this finding: A router permits HTTPS management from Internet addresses without IP-based or identity restrictions. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
Untrusted clients cannot reach the interface and approved administrators can connect. This is the decisive evidence for the original problem: A router permits HTTPS management from Internet addresses without IP-based or identity restrictions. It verifies that the intended corrective control—Limit management HTTPS to an approved admin network with strong authentication—works in the relevant environment; a completed change ticket alone would not prove the outcome at Aster Mutual.
Incorrect Answers
A backup transfer is encrypted and stored with access and integrity controls. This would be relevant evidence for a different failure: Administrators transfer backups over unencrypted FTP to a shared server, usually addressed by Use SCP or SFTP to protected storage with least-privilege service credentials. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: Untrusted clients cannot reach the interface and approved administrators can connect.
An impostor certificate fails the test and a valid management endpoint succeeds. This would be relevant evidence for a different failure: An automation client uses a certificate with the wrong server name yet ignores TLS errors, usually addressed by Validate peer certificate chains and hostnames for API and RESTCONF management calls. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: Untrusted clients cannot reach the interface and approved administrators can connect.
Tunnel events from both peers share an interpretable timestamp sequence. This would be relevant evidence for a different failure: Network devices have inconsistent local clock settings and VPN troubleshooting logs do not align, usually addressed by Configure reliable authenticated NTP sources and verify synchronization status. It does not demonstrate that the current problem at Aster Mutual was resolved. The specific required evidence is: Untrusted clients cannot reach the interface and approved administrators can connect.
