A. B. C. D. E.BD.
Cisco Fabric Services (CFS) distributes the local NTP configuration to all Cisco devices in the network.
After enabling CFS on your device, a network-wide lock is applied to NTP whenever an NTP configuration is started.
After making the NTP configuration changes, you can discard or commit them.
In either case, the CFS lock is then released from the NTP application.
References:
CFS ( Cisco Fabric Services) is a feature in Cisco NX-OS that allows configuration changes to be propagated from a designated "master" switch to other switches in the network. Here are the explanations for the given statements:
A. This statement is not true. CFS is not used to distribute local NTP (Network Time Protocol) configurations. Instead, each device maintains its own NTP configuration.
B. This statement is true. After CFS is enabled, any network-wide lock is applied to NTP configurations whenever a configuration change is started. The lock is released once the change has been committed or discarded. This ensures that multiple administrators don't change the same configuration simultaneously, which can cause configuration errors.
C. This statement is not true. CFS doesn't require that all devices in the network have different VRFs (Virtual Routing and Forwarding) configured for NTP.
D. This statement is not true. CFS can be used to distribute NTP authentication keys automatically across the network.
E. This statement is not true. CFS doesn't require a separate license to be installed. It's a built-in feature in Cisco NX-OS.
Therefore, the correct statements are B and D.
