In which situation would a company register for its own autonomous system number (ASN)?when the companys ISP adds connection points to the Internetwhen additional routers are added to the corporate internetworkwhen more than one interior routing protocol is usedwhen the company uses two or more ISPs4. Consider this routing table entryR 172.16.1.0/24 [120/1] via 200.1.1.1 00:00:27 Serial0/1What type of route is this?a static routea default routea RIP routean OSPF routean EIGRP routea directly-connected route5. What is the difference between interior and exterior routing protocols?Exterior routing protocols are only used by large ISPs. Interior routing protocols are used by small ISPs.Interior routing protocols are used to route on the Internet. Exterior routing protocols are used inside organizations.Exterior routing protocols are used to administer a single autonomous system. Interior routing protocols are used to administer several domains.Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.6. What information is included in RIPv2 routing updates that is not included in RIPv1 updates?metricsubnet maskarea identificationhop countautonomous system number7. Which routing protocol is used to exchange data between two different ISPs?BGPEIGRPOSPFRIP v28. Refer to the exhibit. Which configuration command or commands contributed to the output that is shown?routerA(config-router)# no version 2routerA(config)# interface fa0/0routerA(config-if)# ip address 172.19.0.0 255.255.0.0routerA(config-router)# network 192.168.3.0routerA(config)# no ip default-gateway9. Refer to the exhibit. If all routers are running RIP and network 10.0.0.0 goes down, when will R3 learn that the network is no longer available?in 30 secondsin 60 secondsin 90 secondsImmediately10. What statement is true regarding an AS number?AS numbers are controlled and registered for Internet use.Interior routing protocols require registered AS numbers.ISPs require all customers to have registered AS numbers.All routers at an ISP must be assigned the same AS number.11. What is the purpose of the network command used when configuring RIP?to specify whether RIPv1 or RIPv2 will be used as the routing protocolto allow the router to monitor RIP updates that occur on other routersto identify which networks on the router will send and receive RIP updatesto configure the IP address on an interface that will use RIPto identify all of the remote networks that should be reachable from the router12. Which command would a network administrator use to determine if the routers in an enterprise have learned about a newly added network?router# show ip addressrouter# show ip routerouter# show ip networksrouter# show ip interface briefrouter# debug ip protocolrouter# debug rip update13. What is the purpose of a routing protocol?It is used to build and maintain ARP tables.It provides a method for segmenting and reassembling data packets.It allows an administrator to devise an addressing scheme for the network.It allows a router to share information about known networks with other routers.It provides a procedure for encoding and decoding data into bits for packet forwarding.14. What device enables an ISP to connect with other ISPs to transfer data?border gateway routerDSLAMweb serverinterior router15. Which command will display RIP routing updates as they are sent and received?show ip routeshow ip ripdebug ip ripshow ip protocolsshow ip rip database16. Which part of an IP packet does the router use to make routing decisions?source IP addresssource MAC addressdestination IP addressdestination MAC address17. What two types of businesses would benefit from registering as their own autonomous systems? (Choose two.)a home business with one ISP connectiona global business with connections to multiple local ISPsa medium-sized nationwide business with Internet connectivity through different ISPsa large enterprise with two connections to the same ISPa small ISP with a single Internet connection through a larger ISP18. Which command will display RIP activity as it occurs on a router?debug ip ripshow ip routeshow ip interfaceshow ip protocolsdebug ip rip configshow ip rip database19. Why is fast convergence desirable in networks that use dynamic routing protocols?Routers will not allow packets to be forwarded until the network has converged.Hosts are unable to access their gateway until the network has converged.Routers may make incorrect forwarding decisions until the network has converged.Routers will not allow configuration changes to be made until the network has converged.20. Which two statements describe static routes? (Choose two.)They are created in interface configuration mode.They require manual reconfiguration to accommodate network changes.They automatically become the default gateway of the router.They are identified in the routing table with the prefix SThey are automatically updated whenever an interface is reconfigured or shutdown.21. Which two statements or sets of statements describe differences between link-state and distance vector routing protocols? (Choose two.)Link-state routing protocols routinely use more bandwidth for updates than do distance vector routing protocols.Distance vector routing protocols update all routers at one time. Link-state routing protocols update one router at a time.Link-state routers only know about directly connected routers. Distance vector routers know about every router in the network.Link-state routing protocols update when a change is made. A network using distance vector routing protocols only updates at a specific interval.Distance vector routing protocols have limited information about the entire network. Link state routing protocols know about all routers in the network.In case of similar topologies, networks using link-state routing protocols typically converge more rapidly than do networks using distance vector routing protocols.22.

Which protocol is an exterior routing protocol? BGP EIGRP OSPF RIP2. Which command would a network administrator use to determine if the routers in an enterprise have learned about a newly added network? router# show ip address router# show ip route router# show ip networks router# show ip interface brief router# debug ip protocol router# debug rip update3. Consider this routing table entry R 172.16.1.0/24 [120/1] via 200.1.1.1 00:00:27 Serial0/1 What type of route is this? a static route a default route a RIP route an OSPF route an EIGRP route a directly-connected route4.

Refer to the exhibit. What is the maximum number of RIP routers that could separate HostA and HostB and still leave the hosts with connectivity to each other? 14 15 16 175. Which routing protocol is used to exchange data between two different ISPs? BGP EIGRP OSPF RIP v26. What is the purpose of the network command used when configuring RIP? to specify whether RIPv1 or RIPv2 will be used as the routing protocol to allow the router to monitor RIP updates that occur on other routers to identify which networks on the router will send and receive RIP updates to configure the IP address on an interface that will use RIP to identify all of the remote networks that should be reachable from the router7. What term refers to a group of networks that uses the same internal routing policies and is controlled by a single administrative authority? Internet intranet virtual private network autonomous system8.

Refer to the exhibit. Which configuration command or commands contributed to the output that is shown? routerA(config-router)# no version 2 routerA(config)# interface fa0/0 routerA(config-if)# ip address 172.19.0.0 255.255.0.0 routerA(config-router)# network 192.168.3.0 routerA(config)# no ip default-gateway9. Why is fast convergence desirable in networks that use dynamic routing protocols? Routers will not allow packets to be forwarded until the network has converged. Hosts are unable to access their gateway until the network has converged. Routers may make incorrect forwarding decisions until the network has converged. Routers will not allow configuration changes to be made until the network has converged.10.

Refer to the exhibit. If all routers are running RIP and network 10.0.0.0 goes down, when will R3 learn that the network is no longer available? in 30 seconds in 60 seconds in 90 seconds Immediately11. Which two statements describe static routes? (Choose two.) They are created in interface configuration mode. They require manual reconfiguration to accommodate network changes. They automatically become the default gateway of the router. They are identified in the routing table with the prefix S They are automatically updated whenever an interface is reconfigured or shutdown.12. Which part of an IP packet does the router use to make routing decisions? source IP address source MAC address destination IP address destination MAC address13. In which situation would a company register for its own autonomous system number (ASN)? when the companys ISP adds connection points to the Internet when additional routers are added to the corporate internetwork when more than one interior routing protocol is used when the company uses two or more ISPs14. Which command will display RIP activity as it occurs on a router? debug ip rip show ip route show ip interface show ip protocols debug ip rip config show ip rip database15. What is the difference between interior and exterior routing protocols? Exterior routing protocols are only used by large ISPs. Interior routing protocols are used by small ISPs. Interior routing protocols are used to route on the Internet. Exterior routing protocols are used inside organizations. Exterior routing protocols are used to administer a single autonomous system. Interior routing protocols are used to administer several domains. Interior routing protocols are used to communicate within a single autonomous system. Exterior routing protocols are used to communicate between multiple autonomous systems.16. What two types of businesses would benefit from registering as their own autonomous systems?

Which command is used to view the RIP routing protocol settings and configuration? show version show ip route show interface show ip protocols18. Which command will display RIP routing updates as they are sent and received? show ip route show ip rip debug ip rip show ip protocols show ip rip database19. What is the purpose of a routing protocol? It is used to build and maintain ARP tables. It provides a method for segmenting and reassembling data packets. It allows an administrator to devise an addressing scheme for the network. It allows a router to share information about known networks with other routers. It provides a procedure for encoding and decoding data into bits for packet forwarding.20. Hosts on two separate subnets cannot communicate. The network administrator suspects a missing route in one of the routing tables. Which three commands can be used to help troubleshoot Layer 3 connectivity issues? (Choose three.) Ping show arp Traceroute show ip route show interface show cdp neighbor detail21. What statement is true regarding an AS number? AS numbers are controlled and registered for Internet use.

Which two statements or sets of statements describe differences between link-state and distance vector routing protocols? (Choose two.) Link-state routing protocols routinely use more bandwidth for updates than do distance vector routing protocols. Distance vector routing protocols update all routers at one time. Link-state routing protocols update one router at a time. Link-state routers only know about directly connected routers. Distance vector routers know about every router in the network. Link-state routing protocols update when a change is made. A network using distance vector routing protocols only updates at a specific interval. Distance vector routing protocols have limited information about the entire network. Link state routing protocols know about all routers in the network. In case of similar topologies, networks using link-state routing protocols typically converge more rapidly than do networks using distance vector routing protocols.24.
