What is the probable cause of the problem?

Refer to the exhibits. Router B should advertise the network connected to the E0/0/0
interface to router A and block all other network advertisements. The IP routing table on
router A indicates that it is not receiving this prefix from router B.

A.
An access list on router B is causing the 192.168.3.16/28 network to be denied.

B.
An access list on router B is causing the 192.168.3.32/28 network to be denied.

C.
The distribute list on router B is referencing a numbered access list that does not exist on
router B.

D.
The distribute list on router B is referencing the wrong interface.

Explanation:
This is an unclear question. The question says “Router B should advertise the network
connected to the E0/0/0 interface to router A and block all other network advertisements.
The IP routing table on router A indicates that it is not receiving this prefix from router B.”
That means the network 192.168.3.16/28 (including the IP 192.168.3.21/28) is not received
on router A -> A is the most suitable answer.
Note: Distribute list are used to filter routing updates and they are based on access lists.
