第1题

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 broadcastB. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - pointC. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253

OSPF is enabled on router A. You execute the following command on router A and receive theaccompanying output:RouterAping 224.0.0.5 repeat1Type escape sequence to abort.Sending 1, 1 00 - byte ICMP Echos to 224.0.0.5, timeout is 2 seconds:Reply to request 0 from 10.100.100.1, 4 ms10.100.100.1 is the IP address of a loopback interface on router A.What can you conclude about router A?（）A. Only the router A loopback interface is parti cipating in the OSPF routing processB. None of the router A interfaces are participating in the OSPF routing processC. Router A is using the loopback interface IP address as its OSPF router IDD. Router A does not have any reachable OSPF neighbors

You have implemented mutua l route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one of the EIGRP routers within the EIGRP routing domain, you are seeing some, but not all of the expected routes.What should you verify to troubleshoot this problem?（）A. The border router is using a proper seed metric for OSPFB. The border router is using a proper seed metric for EIGRPC. The administrative distance is set for OSPF and EIGRPD. The missing OSPF routes are present in the routing table of the border routerE. The subnet keyword on the border router in the redistribute OSPF command

When an OSPF design is planned, which implementation can help a router not have memory resource issues?()A. Have a backbone area (area 0) with 40 routers and use default routes to reach external destinationsB. Have a backbo ne area (area 0) with 4 routers and 30,000 external routes injected into OSPFC. Have less OSPF areas to reduce the need for interarea route summarizationsD. Have multiple OSPF processes on each OSPF router. Example, router ospf 1, router ospf 2

On Router R1, process EIGRP 1 is redistributing routes from process OSPF 2, calling route - map fred with the redistribute ospf 2 command. R1 has learned intra - area routes for 10.1.1.0/24 and 10.1.2.0/24 in part due to the Type 2 LSAs known for each subnet. The route map filters route 10.1.1.0/24 and allows 10.1.2.0/24 througH. Which of the following co mmands on router R1 list subnet 10.1.1.0/24?（）A、show ip routeB、show ip eigrp topologyC、show ip ospf topologyD、show ip eigrp topology 10.1.1.0/24
