Example Questions

Which one of the following statements about BGP is FALSE? Identify three characteristics of EIGRP feasible successors? (Choose three.)

The following terms describe various design options for Enterprise connectivity to the Internet. Which of the following imply that the Enterprise connects to two or more ISPs? (Choose two.) Which statement is true about IPv6? Select the best response. 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? Select the best response. An engineer has added the following configuration snippet to an implementation planning document. The configuration will be added to Router R1, whose Fa0/0 interface connects to a LAN to which Routers R2 and R3 also connect. R2 and R3 are already EIGRP neighbors with each other.

Select the best response. Which three are advantages to creating multiple areas in OSPF? (Choose three.) During the IPv6 autoconfiguration, what does the device append to the 64-bit prefix that it receives from the router to create its IPv6 address? Select the best response. Based on the need to limit processing and bandwidth utilization due to dynamic routing protocol operation, the following routing requirements have been specified for your network. - partial and incremental routing updates - only the devices affected by a topology change perform route recomputation - route recomputation only occurs for routes that were affected Which dynamic routing protocol should be deployed in your network to best meet these requirements? Select the best response. Which of the following NSAP addresses is a private, locally administered address? Select the best response. Using the rules for IPv6 addressing, how can the address 2031:0000:240F:0000:0000:09C0:123A:121B be rewritten? Select the best response. You have just completed an OSPF implementation. While executing your verification plan, you determine that R1 is not able to establish full OSPF adjacency with R2. The show ip ospf neighbor command output on R1 shows that R2 is stuck in the INIT state. What could be the cause of this problem? Select the best response. Which condition must be satisfied before an EIGRP neighbor can be considered a feasible successor? Select the best response. During a redistribution of routes from OSPF into EIGRP, an administrator notices that none of the OSPF routes are showing in EIGRP. What are two possible causes? (Choose two.) When implementing a 6to4 tunnel, which IPv6 address is the correct translation of the IPv4 address 192.168.99.1? EIGRP has been configured to operate over Frame Relay multipoint connections. What should the bandwidth command be set to? A network administrator has enabled OSPF across an NBMA network and has issued the command ip ospf network nonbroadcast. Given those facts, which two statements are true? (Choose two.) You are troubleshooting an OSPF problem where external routes are not showing up in the OSPF database. Which two options are valid checks that should be performed first to verify proper OSPF operation? (Choose two.) Which two statements are true about EIGRP manual summarization? (Choose two.) Which of the following is true about routers internal to a totally NSSA area? (Choose two.) Which statement about a non-zero value for the load metric (k2) for EIGRP is true?
