Refer to the exhibits. You are verifying your OSPF implementation, and it does not seem to be functioning properly. What can you conclude from the exhibit and the show running - configuration command output? （）A. The OSPF areas are not configured correctly.B. The wildcard masks for the 10.x .x.x networks are incorrect.C. The 172.16.x.x networks need to be connected to area 0 using virtual links.D. The 172.16.x.x networks are discontiguous. OSPF is automatically summarizing them to 172.16.0.0/16 and data is being black holed.E. There is not enough information to make a determination.

You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds.What could be the cause of this problem?（）A. OSPF authentication errors between some of the routersB. Two routers have the same OSPF router IDC. Issues with mistuned OSPF timersD. OSPF LSA pacing issues between some of the routersE. OSPF neighbor adjacency problems between some of the routers

A. It provides dynamic neighbor discoveryB. It detects unreachable neighbors in 90 second intervalsC. It maintains neighbor relationshipsD. It negotiates correctness parameters between neighboring interfacesE. It uses timers to elect the router witch the fastest links as the designated routerF. It broadcasts hello packets throughout the internetwork to discover all routers that are running OSPF

Half of your network uses RIPv2 and the other half runs OSPF. The networks do not communicate with each other. Which two of these factors describe the impact of activating EIGRP over each separate part？ （）A、EIGRP will not be accepted when configured on the actual RIPv2 routers.B、OSPF will no longer be used in the routing table， because you only have EIGRP internal routes running.C、OSPF will no longer be used in the routing table， because you only have EIGRP external routes running.D、RIPv2 will populate its RIP database but not its routing table， because you only have EIGRP external routes running.E、RIPv2 will populate its RIP database but not its routing table， because you only have EIGRP internal routes running.F、OSPF database will have RIPv2 routes.

You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）A、static route needs to be addedB、floating static route needs to be addedC、bgp backdoor commandD、ospf backdoor command
