Refer to the exhibit. Cisco Fabric Services is enabled in the network. Which type of IP address is used by the Cisco Fabric Services protocol?
The correct answer is B. IPv4 multicast address. Cisco Fabric Services (CFS) over IP uses IPv4 multicast addressing (B) to distribute configuration and state information across the fabric between switches. By default, CFS uses the multicast address 239.255.70.83 to reach all CFS-capable peers in the network without requiring un

Explanation
Cisco Fabric Services (CFS) over IP uses IPv4 multicast addressing (B) to distribute configuration and state information across the fabric between switches. By default, CFS uses the multicast address 239.255.70.83 to reach all CFS-capable peers in the network without requiring unicast sessions to each individual peer. This multicast approach allows CFS to efficiently propagate feature-specific synchronization data (such as for IGMP snooping, NTP, and RSCN) across all participating switches. Unicast, gateway, and anycast addresses are not used by the CFS protocol.
