Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 243

An administrator is testing new configuration on a network device. The network device had a previously established association with the NTP server but is no longer processing time updates. What is the cause of this issue?

Answer options

• A. The server changed its time source to stratum 1.
• B. The network device is sending the wrong password to the server.
• C. NTP authentication has been configured on the network device.
• D. NTP authentication has been configured on the NTP server.

Correct answer: C

Explanation

The correct answer is C because if NTP authentication is configured on the network device, it may not be able to communicate with the NTP server unless the correct credentials are provided. Options A and D do not directly relate to the network device's inability to process time updates, and option B could be a potential issue, but it does not address the specific configuration of authentication which is the main concern here.
