Which three networks is the router at 172.17.10.2 directly connected to? (Choose three)

A.
172.17.0.0/30

B.
172.17.1.0/24

C.
172.17.2.0/24

D.
172.17.3.0/25

E.
172.17.3.128/25

F.
172.17.10.0/24

Explanation:

First, we should notice about the entry in the orange box, it shows that the network 172.17.10.0/24
is directly connected with this router and has a FD of 28160. So we can guess the networks that
directly connected with router at 172.17.10.2 will be shown with an AD of 28160. From that, we
find out 3 networks which are directly connected to the router at 172.17.10.2 (they are green
underlined). The network 172.17.10.0/24 is surely directly connected to the router at 172.17.10.2
(in fact it is the network that links the router at 172.17.10.2 with Core1 router).
