Refer to the exhibit.

In this network, each router has a router ID as shown next to the router.
While working on a software upgrade on R1 and R2, the network administrator notices that when
the upgrade is finished, R4 is the designated router on the link. Is OSPF working correctly on this
link, and why or why not?

A.
Yes, OSPF will never allow an existing DR to be replaced when a new router is connected to a
broadcast network. In this case, the administrator has recently reloaded R1 and R2, so it would be
expected that either R3 or R4 would be the DR on the link.

B.
No, OSPF should always elect the router with the highest router ID as the designated router on
the link. The administrator should call for technical support.

C.
Yes, OSPF is operating correctly, because the router with the lowest router ID should always
be elected designated router on a broadcast link.

D.
There is not enough information provided in the question to answer accurately.
