While troubleshooting an EIGRP routing problem you notice that one of the routers have generated a large number of SIA messages. What are two possible causes for EIGRP Stuck - In -Active routes?（）A、Some quer y or reply packets are lost between the routers.B、The neighboring router starts receiving route updates from this router.C、A failure causes traffic on a link between two neighboring routers to flow in only one direction(unidirectional link).D、Th e neighboring router stops receiving ACK packets from this router.
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
Which of the following are the BEST tools to test connectivity between two hosts？（）A、netstatB、nslookupC、ipconfigD、tracerouteE、pathping
While troubleshooting an EIGRP routing problem you notice that one of the company routers havegenerated a large number of SIA messages.
