The two networks 10.1.1.0/29 and 10.1.1.16/29 are unable to access each other. What can be the cause of this problem? Because RIPv1 is a classless protocol, it does not support this access. RIPv1 does not support discontiguous networks. RIPv1 does not support load balancing. RIPv1 does not support automatic summarization. 32. Refer to the exhibit. What information can be determined 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 33. What does RIP use to reduce convergence time in a larger network? It uses multicast instead of broadcast to send routing updates. It reduces the update timer to 15 seconds if there are more than 10 routes. It uses triggered updates to announce network changes if they happen in between the periodic updates. It uses random pings to detect if a pathway is down and therefore is preemptive on finding networks that are down 34. A network administrator has enabled RIP on routers B and C in the network diagram. Which of the following commands will prevent RIP updates from being sent to Router A? A(config)# router rip A(config-router)# passive-interface S0/0 B(config)# router rip B(config-router)# network 192.168.25.48 B(config-router)# network 192.168.25.64 A(config)# router rip A(config-router)# no network 192.168.25.32 B(config)# router rip B(config-router)# passive-interface S0/0 A(config)# no router rip 35.

What is a possible cause of this problem? The routers are configured with different versions of RIP. R2 is not forwarding the routing updates. The R1 configuration should include the no auto-summary command. The maximum path number has been exceeded. 36. Which two statements are correct about the split horizon with poison reverse method of routing loop prevention? (Choose two.) It is enabled by default on all Cisco IOS implementations. It assigns a value that represents an infinite metric to the poisoned route. It sends back the poisoned route update to the same interface from where it was received. It instructs routers to hold all changes that might affect routes, for a specified period of time. It limits the number of hops a packet can traverse through the network before it is discarded 37. Refer to exhibit. Given the topology shown in the exhibit, what three commands are needed to configure EIGRP on the Paris router? (Choose three.)

A router has EIGRP configured as the only routing protocol. In what way might EIGRP respond if there is no feasible successor route to a destination network and the successor route fails? It broadcasts hello packets to all routers in the network to re-establish neighbor adjacencies. It sends queries to adjacent neighbors until a new successor route is found. It immediately sends its entire routing table to its neighbors. It will set the metric for the failed route to infinity. 39. Refer to the exhibit. Hosts on the BOS Fa0/0 LAN are able to ping the Fa0/1 interface on the JAX router and all interfaces on the BOS and ORL routers. Why would hosts from the 10.0.0.0/24 network not be able to ping hosts on the Fa0/0 LAN of the JAX router? The JAX router has the wrong process ID. The JAX router needs the network 10.0.0.0 0.0.0.255 area 0 command. The JAX router needs the network 192.168.3.0 0.0.0.255 area 0 command. The BOS router needs the network 192.168.3.0 0.0.0.255 area 0 command 40. Which three statements describe the operation of routing with EIGRP? (Choose three.) As new neighbors are discovered, entries are placed in a neighbor table. If the feasible successor has a higher advertised cost than the current successor route, then it becomes the primary route. If hello packets are not received within the hold time, DUAL must recalculate the topology. The reported distance is the distance to a destination as advertised by a neighbor. EIGRP maintains full knowledge of the network topology in the topology table and exchanges full routing information with neighboring routers in every update. EIGRP builds one routing table that contains routes for all configured routed protocols. 41. Refer to the exhibit. What happens to a packet that has 172.16.0.0/16 as the best match in the routing table that is shown? The packet is discarded. The packet is flooded out all interfaces.

What is the meaning of the highlighted value 192? • It is the value assigned by the Dijkstra algorithm that designates the number of hops in the network.0.) • 10.1.1 51.0 network.0/24 52. • Enter the copy run start command to force the router to recognize the configuration.1? • static route to 10.0.0/24 • 0.0. 50.) .0.0.2.) • Router1 is missing a route to the 172.0 network • Router2 is missing a route to the 172.0 network 48.0. 49. Which protocol will be used and how will traffic between the Router1 LAN and Router5 LAN be routed through the network? • RIPv2 will load balance across both paths between Router1 and Router5. Router4.) • OSPF interval timers mismatch • gateway of last resort not redistributed • interface network type mismatch • no loopback interface configured • administrative distance mismatch • inconsistent authentication configuration 57.) • As new neighbors are discovered. entries are placed in a neighbor table. What are three features of CDP? (Choose three. Router2. • EIGRP traffic will use the path Router1. • EIGRP will load balance across both paths between Router1 and Router5. 55. • EIGRP maintains full knowledge of the network topology in the topology table and exchanges full routing information with neighboring routers in every update. • If hello packets are not received within the hold time. DUAL must recalculate the topology. • RIPv2 traffic will use the path Router1.• packet switching • microsegmentation • domain name resolution • path selection • flow control 53.) • tests Layer 2 connectivity • provides a layer of security • operates a OSI layers 2 and 3 • enabled by default on each interface • used for debugging Layer 4 connectivity issues • provides information on directly connected devices that have CDP enabled 54Refer to the exhibit. What is the first step OSPF and IS-IS routers take in building a shortest path first database? • learn about directly connected networks • send hello to discover neighbors and form adjacencies • choose successors and feasible successors to populate the topology table • flood LSPs to all neighbors informing them of all known networks and their link states . Router3. • The reported distance is the distance to a destination as advertised by a neighbor. Which three statements describe the operation of routing with EIGRP? (Choose three. Router5 because it has the least hops. Router5 because it has the best metric. Which of the following should be considered when troubleshooting a problem with the establishment of neighbor relationships between OSPF routers? (Choose three. • If the feasible successor has a higher advertised cost than the current successor route. then it becomes the primary route. All routers in the network are running RIPv2 and EIGRP with default routing protocol settings and have interfaces configured with the bandwidths that are shown in the exhibit. 56. • EIGRP builds one routing table that contains routes for all configured routed protocols.
