Refer to the exhibit.

The correct answer is D. 10.5.74.10/24.

From the exhibit, the ip rule show output includes an entry:

from 10.5.74.144 lookup 1001, which indicates that the management interface (mgmt0) is operating in the 10.5.74.0/24 subnet. This subnet is being used for management-plane communication. Since the question states that the Nexus Dashboard (NDFC) mgmt interface is Layer 2 adjacent to the switch mgmt0, both devices must reside in the same IP subnet to communicate directly without routing.

Therefore, the NDFC management IP must be assigned within the 10.5.74.0/24 network. Among the options, only 10.5.74.10/24 falls within this subnet.

The other options belong to different subnets:

192.168.2.0/24 – unrelated private network

172.18.1.0/24 – different subnet shown in routing rules

10.17.10.0/24 – also unrelated

Because Layer 2 adjacency requires same subnet addressing, selecting an IP within 10.5.74.0/24 ensures proper connectivity, making option D the correct answer.
