Discovery 2 - Module 6

Which two statements are true regarding the advantages of the use of static routes? (Choose two). increased security reduced effort in configuring routes the administrator maintains control over routing easier to implement in a growing network reduces the chance of routing errors increased router resource usage
2	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.

3	What happens to a static route entry in a routing table when the outgoing interface is not available? The route is removed from the table. The router polls neighbors for a replacement route. The route remains in the table because it was defined as static. The router redirects the static route to compensate for the loss of the next hop device.
4	Which of the following are valid static IP routes? (Choose three.) RouterB(config)# ip route 192.168.5.0 255.255.255.0 S1 RouterC(config)# ip route 192.168.1.0 255.255.255.0 S1 RouterA(config)# ip route 192.168.3.0 255.255.255.0 192.168.2.2 RouterB(config)# ip route 192.168.1.0 255.255.255.0 192.168.2.2 RouterC(config)# ip route 192.168.2.0 255.255.255.0 192.168.4.1 RouterA(config)# ip route 192.168.4.0 255.255.255.0 192.168.2.1

5	What two devices are responsible for converting the data from the WAN service provider into a form acceptable by the router? (Choose two). the serial port of the router a modem a switch the ethernet port of the router a CSU/DSU device a DTE device
6	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 database

7	A network administrator has a multi-floor LAN to monitor and maintain. Through careful monitoring, the administrator has noticed a large amount of broadcast traffic slowing the network. Which device would you use to best solve this problem? bridge hub router transceiver
8	Which three correctly pair a routing metric with its description? (Choose three.) hop count - the number of routers traversed to reach a destination bandwidth - the amount of time it takes a packet to travel a link load - the amount of activity on a link delay - the link speed reliability - the error rate on a link

9	Refer to the exhibit. Hosts on the 192.168.1.0 and 192.168.4.0 networks cannot communicate. What is the cause of this problem? improper address on serial 0/1/0 improprer address on fastethernet 0/0 incorrect network statements the fa0/0 must be configured as passive
10	Refer to the exhibit. Which static route should be configured on Router1 so that host A will be able to reach host B on the 172.16.0.0 network? ip route 192.168.0.0 172.16.0.0 255.255.0.0 ip route 172.16.0.0 255.255.0.0 192.168.0.1 ip route 172.16.0.0 255.255.0.0 S0/0/1 ip route 172.16.0.0 255.255.0.0 S0/0/0

11	What are the three functions provided by the RIPv2 protocol? (Choose three.) learning the available routes to all destinations providing an addressing scheme for identifying networks placing the best route in the routing table removing routes from the routing table when they are no longer valid carrying user data to the destination network informing LAN hosts of new default gateway addresses
12	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 system

13	Which statement is true concerning directly connected routes? They appear in the routing table as soon as cables are connected to the router. They appear in the routing table when an IP address is configured on an interface. They appear in the routing table when the no shut command is entered in the router interface configuration mode. They appear in the routing table when the show interface shows the interface is up, line protocol is up.
14	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.
15
	By default, which two factors does EIGRP use for calculating its metric? (Choose two.) hop count bandwidth cost delay administrative distance

16	A network administrator has configured a border router as shown. What is the effect of the network command configuration? Router(config)#router bgp 1100 Router(config-router)#network 209.165.201.0 defines a neighbor network advertises an internal route defines a default static route to the ISP creates a route to a remote AS network
17	Which three factors influence the BGP routing decisions of border gateway routers? (Choose three.) local preferences LAN bandwidth WAN connection type AS path routing policies network congestion

18	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 update
19	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 detail

20	The administrator for one autonomous system (AS) creates routing rules based on the security, performance, and reliability of each connecting AS. What are these rules called? routing protocols routing policies routing tables route maps
