Refer to the exhibit.

Why are two OSPF designated routers identified on Core-Router?

A.
Core-Router is connected to more than one multi-access network.

B.
The router at 208.149.23.130 is a secondary DR in case the primary fails.

C.
Two router IDs have the same OSPF priority and are therefore tied for DR election

D.
The DR election is still underway and there are two contenders for the role.

Explanation:
OSPF elects one DR per multi-access network. In the exhibit there are two DR so there must
have more than one multi-access network.
