Which two statements are true about classlessrouting protocols?

Refer to the exhibit. How many routes are childroutes?134627. A router has EIGRP configured as the only routingprotocol.
In what two ways does EIGRP respond ifthere is no feasible successor route to a destinationnetwork and the successor route fails? (Choose two.)It broadcasts hello packets to all routers in the network tore-establish neighbor adjacencies.It sends queries to adjacent neighbors until a new successorroute is found.It immediately sends its entire routing table to its neighbors.It sends queries to adjacent neighbors until the lost route isunknown to the neighbors.It automatically forwards traffic to a fallback default routeuntil a successor route is found.28. Refer to the exhibit. Packets destined to which twonetworks will require the router to perform a recursivelookup?

(Choose two.)The administrative distance of EIGRP has been set to 50.All routes are stable.The show ip eigrp topology command has been run on R1.The serial interface between the two routers is down.Each route has one feasible successor.30. Refer to the exhibit. All routers are properlyconfigured with default configurations and are runningtheOSPFroutingprotocol.Thenetworkis fullyconverged. A host on the 192.168.3.0/24 network iscommunicating with a host on the 192.168.2.0/24network. Which path will be used to transmit the data?The data will be transmitted via R3-R2.The data will be transmitted via R3-R1-R2.The traffic will be load-balanced between two paths — onevia R3-R2, and the other via R3-R1-R2.The data will be transmitted via R3-R2, and the other pathvia R3-R1-R2 will be retained as the backup path.31.

Refer to the exhibit. All routes are advertised andfully operational on all routers. Which statement is trueabout the path that the data will take from router A torouter B?If EIGRP is used with default configurations, the data will beequally distributed between two paths — A, D, B and A, C,D.If RIPv1 is used with default configurations, the data will beload-balanced on all paths.IfEIGRPandOSPFarebothusedwithdefaultconfigurations, the data will be sent through paths learnedby the OSPF protocol.If RIPv2 is used with default configurations, the data will beequally distributed between two paths — A, D, B and A, C,D.39. Refer to the exhibit.

R3 can ping R1, but the tworouters are unable to establish a neighbor adjacency.Whatshouldthenetworkadministratordototroubleshoot this problem?Check if the interfaces of the routers are enabled.Check the hello and dead intervals between the routers.Check the process ID of both routers.Check if CDP is enabled on all the routers.40. Refer to the exhibit. What information can bedetermined from the highlighted output?R1 is originating the route 172.30.200.32/28.Automatic summarization is disabled.The 172.30.200.16/28 network is one hop away from R1.A classful routing protocol is being used.41. Which two router component and operation pair arecorrectly described? (Choose two.)DRAM - loads the bootstrapRAM - stores the operating systemFlash - executes diagnostics at bootupNVRAM - stores the configuration fileROM - stores the backup configuration filePOST - runs diagnostics on hardware modules42.
