Answer: A

Explanation:

From the output we can see there are 2 NHRP Peers. The first one with the NBMA Address of 172.18.16.2 and the “Attribute” (Attrb) of Static (S) so we can deduce it is the Hub device.

Therefore the second one must be the remaining Spoke device with the attribute of Dynamic (D).

–> S – Static, D – Dynamic, I – Incomplete

N – NATed, L – Local, X – No Socket

# Ent –> Number of NHRP entries with same NBMA peer

NHS Status: E –> Expecting Replies, R –> Responding, W –> Waiting

UpDn Time –> Up or Down Time for a Tunnel

Interface: Tunnel1, IPv4 NHRP Details

Type: Spoke, NHRP Peers:2,
