Refer to the exhibit.
R5 is the current DR on the network, and R4 is the BDR. Their interfaces are flapping, so a network engineer wants the OSPF network to elect a different DR and BDR.
Which set of configurations must the engineer implement?
A.R4(config)#interface gi0/0 R4(config-if)#ip ospf priority 20 R5(config)#interface gi0/0 R5(config-if)#ip ospf priority 10 B.R2(config)#interface gi0/0 R2(config-if)#ip ospf priority 259 R3(config)#interface gi0/0 R3(config-if)#ip ospf priority 256 C.R5(config)#interface gi0/0 R5(config-if)#ip ospf priority 120 R4(config)#interface gi0/0 R4(config-if)#ip ospf priority 110 D.R3(config)#interface gi0/0 R3(config-if)#ip ospf priority 255 R2(config)#interface gi0/0 R2(config-if)#ip ospf priority 240正确答案D
