The two main functions of a router in a network are packet switching and path selection.When a router receives a packet from an interface, the router will query the routing table, perform path selection, find the outgoing outgoing interface, and then switch the packet to the outgoing interface.Therefore, AC is correct. The access layer security mentioned in option B is implemented by the switch; the VLAN membership assignment mentioned in option D is also done by the switch; the bridging between LAN segments mentioned in option E is done by the switch or bridge: option F mentions that the broadcast domain can be differentiated, and the router can isolate the broadcast domain, and each interface of the router is a broadcast domain, but the number of interfaces of the router is generally very small. It is a bit inappropriate to speak of differencing.2. Solution: Question C asks: A user on the 172.17.22.0 network segment cannot access the server on the 172.31.5.0 network segment. The network administrator connects to the Coffee router through the Console port, executes the showip route command and is able to ping through to that server. According to the output of the showip route command in the figure, what might be the reason why a user on the 172.17.22.0 network segment cannot access the server on the 172.31.5.0 network segment? The question is well posed and has a fair amount of difficulty. However, there is an error in the question itself, and the judgement is based on one: the candidate notes the routing table output "S* 0.0.0.0 [1/0] via 172.19.22.2",Here a default route is shown, and the next hop of the default route is 172.19.22.2,The router's routing table does not have a routing entry to 172.19.22.2 If the default route on the Coffee router is misconfigured, the Coffee router cannot ping the server on the 17231.5.0 network segment, but the title says it can. If the output of 172.19.22.2 is changed to 172.18.22.2, it is correct. The next choice is to use the elimination method: option A says that the network is not fully converged, but the diagram uses static routes, not dynamic routes, so there is no problem of fully converged routes; option B says that the IP routing protocol is not enabled, and if the IP routing protocol is not enabled, the Coffee router will not appear in the routing table; option C says that the static routes are not configured correctly, and this possibility exists.If there is no error in the title, the Coffee router's routing table will appear as "S* 0.0.0.0 [1/0] via 172.18.22.2", and the Coffee router can ping through to the server on the 172.3150 network segment, but Tea router is not configured with a static route for 172.17.22.0, which will result inusers on the 172.17.22.0 network segment cannot access the server on the 172.31.5.0 network segment; option D says that the Fast Ethernet interface on the Coffee router is disabled, and if the interface is disabled, the routing table will not be out "C172.18.22.0..." route entry; option E says that the neighbor relationship table is not properly updated and that there is no neighbor relationship table update in the static route; option F says that the Coffee router's routing table is not updated and that the static route does not need to be updated. In summary, the correct answer would be C.
