RouterA#debug ip ospf events OSPF events debugging is on RouterA# 04:43:16: OSPF: Rcv pkt from 10.3.0.2, Ethernet0/1, area 0.0.0.1 mismatch area 0.0.0.2 in the header 04:43:19: OSPF: Rcv hello from 10.100.100.3 area 0 from Ethernet0/0 10.1.0.1 04:43:19: OSPF: End of hello processing Refer to the exhibits. What can be done to fix the problem?（）
A. Change router B E0/1 interface to area 0.
B. Change router A interface E0/1 to area 0.0.0.2.
C. Configure the E0/1 i nterfaces of router A and router B to be in area 0.
D. Shut down the E0/1 interfaces in router A and router B as OSPF does not allow "back doors" between areas.
E. Remove the E0/1 interfaces in router A and router B from the OSPF process. Use static rou tes to route data directly from router A to router B to avoid passing data through router C in area 0.
Refer to the exhibit. Router C was configured so that it could form an adja cency with three OSPF neighbors, one connected to each of its three physical interfaces. Which statement is correct about router C?（）
A. It is configured and functioning correctly as an OSPF internal router.
B. It is configured and functioning correc tly as an ABR attached to stub area 4.
C. It is configured and functioning correctly as an ASBR attached to external area 4.
D. It is configured and functioning correctly as an ABR attached to totally stubby area 4.
E. It is not configured correctly to function as specified.
A. Apply the area 4 stub command to all routers in the area
B. On the ABR, use the area 4 stub command with the no - summary keyword
C. On the ABR, specify a default cost for the area with the area default - cost command
D. On the ABR, use the default - information originate command to inject a default route into area 4
E. Use the auto - cost command on each router in the area to automatically determine the cost to other OSPF areas
Your network has a mixture of Fast Ethernet and Gigabit Ethernet links. What needs t o be done to ensure optimal data routing when using OSPF?（）
A. Nothing. OSPF will determine the most optimal path for routing data by default.
B. Adjust the hello and dead timers for more rapid detection of link failures.
C. Increase the reference - bandw idth used to calculate the interface default metrics, on all routers in your network.
D. Set the priority values on every broadcast interface to ensure that the designated and backup designated routers are the routers with the most processor and memory resources.
Refer to the exhibit. Two routers are connected by Frame Relay and are running OSPF bet ween them. Each router has been configured with the appropriate network statements under router ospf 1, but the routers are not forming an adjacency. Which of the following three commands could be configured on each router to correct this problem?（）
A. RouterC(config - if)#ip ospf network broadcast RouterD(config - if)#ip ospf network broadcast
B. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - point
C. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3
D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253
