Refer to the exhibit. Which three statements are true of the routing tablefor Router1? (Choose three.)The route to network 172.16.0.0 has an AD of 156160.Network 192.168.0.16 can best be reached using FastEthernet0/0.The AD of EIGRP routes has been manually changed to a value other than thedefault value.Router1 is running both the EIGRP and OSPF routing process.Network 172.17.0.0 can only be reached using a default route.No default route has been configured.8. Refer to the exhibit. The ORL router is unable to form a neighborrelationship with the JAX router. What is a possible cause of this problem?Router JAX has the wrong autonomous-system number.The command network 192.168.2.0 is missing from the EIGRP configuration on theJAX router.Automatic summarization is not disabled on the JAX router.Стр. 7 из 2701.04.2009 0:45CISCO CCNA Certifications: CCNA 2 UPDATEDfile:///D:/botalka/%D1%81%D0%B8%D1%81%D1%8C%D0%BA...Router JAX has the wrong IP address on the Fa0/1 interface.9.
Which statement is true regarding routing metrics?All routing protocols use the same metrics.EIGRP uses bandwidth as its only metric.Routers compare metrics to determine the best route.The larger metric generally represents the better path.10. Which three statements are true of holddown timers? (Choose three.)used by link state routing protocols to prevent routing loopsprevent update messages from reinstating a route that may have gone badallow routers to still forward packets to destination networks that are in holddownlimit the number of hops a packet can traverse through the network before it isdiscardedprevent a router advertising a network through the same interface from which thenetwork was learnedpermit lower metric updates received from any neighboring router to reinstate theroute to a possibly down network1.
A router has learned about a network through static and dynamic routingprocesses. Which route will be used to reach network 192.168.168.0?D 192.168.168.0/24 [90/2195456] via 192.168.200.1, 00:00:09, Ethernet0O 192.168.168.0/24 [110/1012] via 192.168.200.1, 00:00:22, Ethernet0R 192.168.168.0/24 [120/1] via 192.168.200.1, 00:00:17, Ethernet0S 192.168.168.0/24 [1/0] via 192.168.200.112. The Suffolk router is directly connected to the networks shown in thegraphic and has a default route that points to the Richmond router. Allinterfaces are active and properly addressed. However, when theworkstation on network 172.29.5.0/24 sends a packet to destinationaddress 172.29.198.5, it is discarded by the Suffolk router. What can be areason for this result?The ip classless command is not enabled on the Richmond router.The route was ignored if the Richmond router did not include the 172.29.198.0/24network in its routing updates.The Richmond router is in a different autonomous system than the Suffolk router.The ip subnet-zero command was not configured on the Suffolk router.The ip classless command is not enabled on the Suffolk router.13.
Which three statements are true regarding the encapsulation andde-encapsulation of packets when traveling through a router? (Choosethree.)The router modifies the TTL field, decrementing it by one.The router changes the source IP to the IP of the exit interface.The router maintains the same source and destination IP.The router changes the source physical address to the physical address of the exitinterface.The router changes the destination IP to the IP of the exit interface.The router sends the packet out all other interfaces, besides the one it entered therouter on.14. Which of the following are required when adding a network to the OSPFrouting process configuration? (Choose three.)network addressloopback addressautonomous system numbersubnet maskwildcard maskarea ID15. Refer to the exhibit.
The routers in the exhibit are running the EIGRProuting protocol. What statement is true regarding how packets will travelfrom the 172.16.1.0/16 network to the 192.168.200.0/24 network?The router chooses the first path that it learned and installs only that route in therouting table.The router chooses the path with the lowest administrative distance and installs onlythat route in the routing table.The router chooses the highest routing ID based on the advertised network IPaddresses and installs only that route in the routing table.The router installs all the equal cost paths in the routing table but sends packets outonly one, holding the others in reserve in case the primary route goes down.The router installs all the equal cost paths in the routing table and performs equalcost load balancing to send packets out multiple exit interfaces.16.
Which of the following could describe the devices labeled "?" in thegraphic? (Choose three.)DCECSU/DSULAN switchModemhub17. 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 successorroute, then it becomes the primary route.If hello packets are not received within the hold time, DUAL must recalculate thetopology.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 andexchanges full routing information with neighboring routers in every update.EIGRP builds one routing table that contains routes for all configured routedprotocols.Стр.

Itis suspected that the problem is with the addressing scheme. What is theproblem with the addressing used in the topology?The address assigned to the Ethernet0 interface of Router1 is a broadcast addressfor that subnetwork.The subnetwork configured on the serial link between Router1 and Router2 overlapswith the subnetwork assigned to Ethernet0 of Router3.The subnetwork assigned to the Serial0 interface of Router1 is on a differentsubnetwork from the address for Serial0 of Router2.The subnetwork assigned to Ethernet0 of Router2 overlaps with the subnetworkassigned to Ethernet0 of Router3.19. Refer to the exhibit.
Packets destined to which two networks willrequire the router to perform a recursive lookup? (Choose two.)10.0.0.0/864.100.0.0/16128.107.0.0/16172.16.40.0/24192.168.1.0/24192.168.2.0/2420. Refer to exhibit. A company network engineer enters the followingcommands in the routers:R1(config)# ip route 10.1.1.0 255.255.255.0192.168.0.2R2(config)# ip route 10.1.2.0 255.255.255.0 192.168.0.1Whenthe engineer enters the show ip route command on R1, the routing tabledoes not display the static route to the 10.1.1.0 network.
All R1 and R2interfaces are correctly addressed per the graphic. What is a logical nextstep that the engineer could take in order to make the static route displayin the routing table in R1?Enter default routes in R1 and R2.Enable the R1 and R2 serial interfaces.Configure the static route to use an exit interface instead of a next-hop address.Enter the copy run start command to force the router to recognize the configuration.21.
When the show cdp neighbors command is issued from Router C, whichdevices will be displayed in the output?D, SWH-2A, B, DSWH-1, SWH-2B, DSWH-1, A, BA, B, D, SWH-1, SWH-222. Refer to the exhibit. R1 knows two routes, Path A and Path B, to theEthernet network attached to R3. R1 learned Path A to network 10.2.0.0/16from a static route and Path B to network 10.2.0.0/16 from EIGRP. Whichroute will R1 install in its routing table?Both routes are installed and load balancing occurs across both paths.The route via Path B is installed because the EIGRP route has the best metric tonetwork 10.2.0.0/16.The route via Path A is installed because the static route has the best metric tonetwork 10.2.0.0/16.The route via Path B is installed because the EIGRP route has the lowestadministrative distance to network 10.2.0.0/16.The route via Path A is installed because the static route has the lowestadministrative distance to network 10.2.0.0/16.23.
