The Dev-1 and Dev-3 routers are OSPF neighbors over the Ethernet 0/0 connection. Based
on the show ip ospf neighbor output from the Dev-1 and Dev-3 routers, which statement is
true?

A.
Dev-1 is the DR because it has a lower OSPF router ID.

B.
Dev-3 is the DR because it has a higher OSPF router priority.

C.
Both Dev-1 and Dev-3 are using the default OSPF router priority.

D.
Dev-3 is the DR because it has a lower OSPF router ID.

E.
Dev-1 is the DR because it has a higher OSPF router priority.

Explanation:
The output shown above displays information about the neighbors, so from Dev-3 we see
that the priority of Dev-1 is 2, and that Dev-1 is the DR. From Dev-1 we can see that its
neighbor (Dev-3) is the BDR and has an OSPF priority of 1.
