Refer to the exhibit. Routers A and B are directly connected. Given the configuration, how many EIGRP routes will router B see in its routing table?

A.
0

B.
1

C.
2

D.
3

E.
4

Explanation:
In this question, router A does not advertise its network 10.10.1.0 0.0.0.255? in the EIGRP process (the network connected with router B) so no EIGRP neighbor relationship is established between two routers. If we use the show ip route command on both routers, we just see a directly connected network 10.10.1.0/24 like this:

For your information, even if we use the network 10.10.1.0 0.0.0.255? in the EIGRP process of router A we still dont see any EIGRP route because router A does not have any interfaces belonging to networks 10.1.1.0/24, 10.2.1.0/24, 172.16.2.0/24 -> it will not advertise these networks to router B.
