A network administrator has enabled RIP on routers B and C in thenetwork diagram. Which of the following commands will prevent RIPupdates from being sent to Router A?A(config)# router ripA(config-router)# passive-interface S0/0B(config)# router ripB(config-router)# network 192.168.25.48B(config-router)# network 192.168.25.64A(config)# router ripA(config-router)# no network 192.168.25.32B(config)# router ripB(config-router)# passive-interface S0/0A(config)# no router rip24. Refer to the exhibit. The network administrator is testing networkconnectivity by issuing the tracert command from host A to host B.
Giventhe exhibited output on host A, what are two possible routing table issueson the network? (Choose two.)Router1 is missing a route to the 172.16.0.0 networkRouter1 is missing a route to the 192.168.1.0 networkRouter2 is missing a route to the 10.0.0.0 networkRouter2 is missing a route to the 172.16.0.0 networkRouter3 is missing a route to the 10.0.0.0 networkRouter3 is missing a route to the 192.168.0.0 network25.
Refer to the exhibit. What will happen if interface Serial0/0/1 goesdown on Router1?The Dijkstra algorithm will calculate the feasible successor.DUAL will query neighbors for a route to network 192.168.1.0.Neighbor 172.16.3.2 will be promoted to the feasible successor.Traffic destined to the 192.168.1.0 network will be dropped immediately due to lackof a feasible successor.26.
Refer to the exhibit. Pings are failing between HostA and HostB. Thenetwork administrator discovers that Router1 does not have a route to theСтр. 9 из 2701.04.2009 0:45CISCO CCNA Certifications: CCNA 2 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...172.16.0.0 network. Assuming Router2 is configured correctly, which twostatic routes could be configured on Router1 to enable Host A to reachnetwork 172.16.0.0?

Refer to the exhibit.
The results of the show ip route command aredisplayed in the graphic for Router R2. Which route will be selected for apacket with a destination address of 10.1.4.1?static route to 10.1.0.0/22RIP route to 10.1.0.0/23RIP route to 10.1.0.0/240.0.0.0/0 via 192.168.0.128. Refer to the exhibit. The network is running the RIP routing protocol.Network 10.0.0.0 goes down. Which statement is true regarding how therouters in this topology will respond to this event?Router4 will learn about the failed route 30 seconds later in the next periodicupdate.Split horizon will prevent Router4 from fowarding packets to the 10.0.0.0 networkuntil the holddown timer expires.Router5 immediately flushes the unreachable route from its routing table.Router5 will send Router4 a triggered update with a metric of 16 for network10.0.0.0.29. Refer to the exhibit.
When troubleshooting a network, it is important tointerpret the output of various router commands. On the basis of theexhibit, which three statements are true? (Choose three.)The missing information for Blank 1 is the command show ip route.The missing information for Blank 1 is the command debug ip route.The missing information for Blank 2 is the number 100.The missing information for Blank 2 is the number 120.The missing information for Blank 3 is the letter R.The missing information for Blank 3 is the letter C.30. A network administrator has configured a default route on Router_A butit is not being shared with adjacent Router_B and the other routers in theOSPF area. Which command will save the administrator the time andtrouble of configuring this default route on Router_B and all of the otherrouters in the OSPF area?Router_A(config-router)# ospf redistribute default-routeRouter_B(config-router)# ospf redistribute default-routeRouter_A(config-router)# default-information originateRouter_B(config-router)# default-information originateRouter_A(config-router)# ip ospf update-defaultRouter_B(config-router)# ip ospf update-default31.
Refer to the exhibit. The network administrator issues the command noip classless on Router1. What forwarding action will take place on a packetthat is received by Router1 and is destined for host 192.168.0.26?The packet will be dropped.The packet will be forwarded to the gateway of last resort.The packet will match the 192.168.0.0 network and be forwarded out Serial 0/0.The packet will most closely match the 192.168.0.8 subnet and be forwarded outSerial 0/1.32.
Refer to the exhibit. A packet enters Router1 with a destination IP of172.16.28.121. Which routing table entry will be used to forward thispacket to the destination address?172.16.0.0/16 [1/0] via 192.168.0.1172.16.0.0/20 [1/0] via 192.168.0.9172.16.16.0/20 [1/0] via 192.168.0.170.0.0.0/0 is directly connected, Serial0/0/133. The network administrator configures the router with the ip route172.16.1.0 255.255.255.0 172.16.2.2 command. How will this route appearin the routing table?C 172.16.1.0 is directly connected, Serial0/0S 172.16.1.0 is directly connected, Serial0/0C 172.16.1.0 [1/0] via 172.16.2.2S 172.16.1.0 [1/0] via 172.16.2.234. Using default settings, what is the next step in the router bootsequence after the IOS loads from flash?Perform the POST routine.Search for a backup IOS in ROM.Load the bootstrap program from ROM.Load the running-config file from RAM.Locate and load the startup-config file from NVRAM.35. What does RIP use to reduce convergence time in a larger network?It reduces the update timer to 15 seconds if there are more then 10 routes.It uses triggered updates to announce network changes if they happen in betweenthe periodic updates.It uses random pings to detect if a pathway is down and therefore is preemptive onfinding networks that are down.It uses multicast instead of broadcast to send routing updates.36.

Refer to the exhibit. What is the most efficient summarization of theroutes attached to router R1?198.18.0.0/16198.18.48.0/21198.18.32.0/22198.18.48.0/23198.18.49.0/23198.18.52.0/2238. Refer to the exhibit. All router interfaces are configured with an IPaddress and are operational. If no routing protocols or static routes areconfigured, what information will be included in the show ip routecommand 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 inthe routing table.The routing table will be empty because routes and dynamic routes have not beenconfigured.A default route is automatically installed in the routing table to allow connectivitybetween the networks.39.
Refer to the exhibit. How many routes are both level 1 and qualify foruse as an ultimate route?12345640. When presented with multiple valid routes to a destination, whatcriteria does a router use to determine which routes to add to the routingtable?The router selects the routes with the best metric. All routes that have the samebest metric are added to the routing table.The router first selects routes with the lowest administrative distance. The resultingroutes are then prioritized by metric and the routes with the best metric are addedto the routing table.The router selects the routes with the lowest administrative distance.
