Implementing Cisco Application Centric Infrastructure (DCACI) — Question 155

All nodes in a Cisco ACI fabric are raising NTP faults. The Date and Time policy is configured with the IP address of two NTP servers and both servers are reachable via the out-of-band management network. Also, the out-of-band EPG has been selected as the management EPG. Which configuration clears the NTP faults?

Answer options

• A. Add the NTP server IPs to the external management instance profile.
• B. Create a node management address policy that includes all nodes in the fabric.
• C. Configure and apply an out-of-band contract to the out-of-band EPG.
• D. Directly attach both NTP servers to the Cisco ACI fabric via a leaf switch.

Correct answer: C

Explanation

The correct answer is C because applying an out-of-band contract to the out-of-band EPG ensures that the NTP servers can communicate properly with the nodes in the fabric. The other options do not directly address the contract requirements needed for NTP synchronization within the ACI environment.
