Take Assessment Take Assessment - ERouting Practice Final Exam - CCNA Exploration: Routing Protocols and Concepts (Version 4.0) Time Remaining: 00:51:58 1 Refer to the exhibit. All router interfaces are configured with an IP address and are operational. If no routing protocols or static routes are configured, what information will be included in the show ip route command output for router A? All of the 192.168.x.0 networks will be in the routing table. Routes to networks 192.168.1.0/24, 192.168.2.0/24, and 192.168.3.0/24 will be in the routing table. The routing table will be empty because routes and dynamic routes have not been configured. A default route is automatically installed in the routing table to allow connectivity between the networks. 2 The network shown in the diagram is having problems routing traffic. It is suspected that the problem is with the addressing scheme. What is the problem with the addressing used in the topology? The address assigned to the Ethernet0 interface of Router1 is a broadcast address for that subnetwork. The subnetwork configured on the serial link between Router1 and Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3. The subnetwork assigned to the Serial0 interface of Router1 is on a different subnetwork from the address for Serial0 of Router2. The subnetwork assigned to Ethernet0 of Router2 overlaps with the subnetwork assigned to Ethernet0 of Router3. 3 How does route poisoning prevent routing loops? New routing updates are ignored until the network has converged. Failed routes are advertised with a metric of infinity. A route is marked as unavailable when its Time to Live is exceeded. The unreachable route is cleared from the routing table after the invalid timer expires. 4 A network administrator needs to configure a single router to load-balance the traffic over unequal cost paths. Which routing protocol should the administrator use? EIGRP OSPF RIPv1 RIPv2 頁 1 / 2 2011/1/7 http://assessment.netacad.net/virtuoso/delivery/pub-doc/exam.shtml 5 Refer to the exhibit. The command ip route 0.0.0.0 0.0.0.0 S0/0/0 is run on router R2. What are the two results of this command? (Choose two.) A static route will be updated in the routing table. The traffic from the Internet will be directed to R2....
