ccna 200 301 syllabus design and material development for schools.QUESTION Q: Referring to the diagram, how will Router A choose the path to 10.1.2.0/24 when configured with different routing protocols (choose three)? Option C says that if you are using EIGRP, only AD is placed in the routing table by default, and EIGRP uses the metric of bandwidth+delay. Delay. In the default case, the formula for the metric value is: (10000M/min bandwidth on the link + delay sum /10)*256, T1 is L544Mb/s link, the delay of T1 should be less than 56Kb/s delay, even if the delay is equal, the impact of delay on the metric value is far less than the impact of bandwidth, the link metric value of ABD and ACD should be less than the metric value of AD link Therefore, option C is incorrect; option D is correct; option E says that if EIGRP and OSPF are configured on the network at the same time, the routes of EIGRP will be placed in the routing table, and according to the routing principle, for the same network, the smaller the administrative distance is, the more priority is given to EIGRP, the administrative distance of EIGRP is 90, and the administrative distance of OSPF is 110, EIGRP takes priority, so it is correct; option F is The administrative distance of EIGRP is 90, and the administrative distance of OSPF is 110.12.Solution: Question D asks: A routing protocol requires support for the following features: (1) authentication support for routing updates; (2) support for IP address saving architectures (VLSM support is required here); (3) multi-vendor support; and (4) more than 50 routers in the network. Which routing protocol meets these requirements? RIPvl does not support authentication and does not support VLSM,you can exclude option A-EIGRP is Cisco's privateThe size of the network can exceed 50 routers, and RIPv2 would be difficult to handle because RIP can only support a maximum of 15 hops, so you can eliminate option B. Finally, only option D, OSPF, can meet the requirements.Solution: Question D asks: A network administrator troubleshoots the OSPF configuration of routers R1 and R2. The two routers cannot establish an adjacency on a common Ethernet link.establish an adjacency relationship. Based on the information in the figure, what caused the neighbor relationship between the two routers to fail to be established? Referring to Section 8.2.4 of this chapter, for two routers to establish an adjacency relationship, Hell. some parameters in the message have to be\276The attention snail Chapter 8 OSPF*** I08match to be possible, and these parameters include Hello time and Dead time, Area id > special area identifier (not covered in CCNA), and authentication to pass. Then compare the contents of R1 and R2 in the figure and you can see that their Hello time and Dead time are different, so their neighbor relationship cannot be established.277 4illi.iEOTZMI' ------------------------------------------------------------------- ----------------------------
