Question 450
At Oceanview Payments, a team reports that it corrected the following problem affecting regulated payments and credentialed access: Administrators transfer backups over unencrypted FTP to a shared server. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
A backup transfer is encrypted and stored with access and integrity controls. This is the decisive evidence for the original problem: Administrators transfer backups over unencrypted FTP to a shared server. It verifies that the intended corrective control—Use SCP or SFTP to protected storage with least-privilege service credentials—works in the relevant environment; a completed change ticket alone would not prove the outcome at Oceanview Payments.
Incorrect Answers
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 Oceanview Payments was resolved. The specific required evidence is: A backup transfer is encrypted and stored with access and integrity controls.
A packet inspection shows protected monitoring traffic and a v2c attempt is rejected. This would be relevant evidence for a different failure: Monitoring credentials are sent in plaintext SNMPv2c strings across untrusted paths, usually addressed by Use SNMPv3 authPriv where supported and restrict manager addresses. It does not demonstrate that the current problem at Oceanview Payments was resolved. The specific required evidence is: A backup transfer is encrypted and stored with access and integrity controls.
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 Oceanview Payments was resolved. The specific required evidence is: A backup transfer is encrypted and stored with access and integrity controls.
