Which of the following would correct this error? RouterB(config)# router igrp RouterB(config-router)# no network 192.169.3.0 RouterB(config)# router igrp 46 RouterB(config)# no network 192.169.3.0 RouterB(config)# network 192.168.3.0 RouterB(config)# router igrp 100 RouterB(config-router)# network 192.169.3.0 RouterB(config-router)# no network 192.168.3.0 RouterB(config)# router igrp 100 RouterB(config-router)# no network 192.169.3.0 RouterB(config-router)# network 192.168.3.0 20 Routers in an OSPF network collect and advertise what information to other routers in the network? (Choose three.) the names of neighboring routers the status or router interfaces the status of all directly connected switches the IOS version of the neighboring routers the total path cost of the links to neighboring routers 21 Which of the following functions are initiated by the router configuration files? (Choose three.) making decisions regarding the best path maintaining instructions for POST diagnostics controlling the flow of traffic in and out of the router performing packet buffering and maintaining packet-hold queues specifying the correct set up and use of routed and routing protocols 22 Which of the following statements about the TTL of a datagram are true? (Choose three.) The TTL value matches the maximum hop count defined by the routing protocol. The TTL value is written in the Ethernet frame header. When the TTL value reaches 0, the packet is discarded. A router decreases the TTL value by one as the router forwards the packet. The TTL of a RIP packet is 16. Faulty routing information will maintain the TTL of a packet at the same value. 23 Which command will display the status of the carrier detect signal and keepalive messages for a router running CDP? Router# show cdp entry Router# show cdp neighbors Router# show cdp interface Router# show cdp 24 A client needs to access more than one network service running on a local server.

(Choose two.) If RouterC receives a packet interface Serial 1. If RouterA receives a packet out interface Ethernet 0. If RouterA receives a packet interface Serial 1. If RouterB receives a packet interface Serial 0. If RouterA receives a packet out interface Serial 1. which of the following statements are destined for 10.5.183.46, it will be forwarded out destined for 192.168.3.146, it will be forwarded destined for 10.5.27.15, it will be forwarded out destined for 10.5.27.83, it will be forwarded out destined for 172.16.55.101, it will be forwarded 27 Why is having an interface description useful? A user can telnet to the router using the interface description. The interface description is a shortcut way to edit running-config. The interface desciption helps identify distant network connections. The interface will remain inactive until an interface description is applied. 28 Refer to the network graphic. A packet needs to travel from Router_F to Router_A. Which path would be selected by the IGRP routing protocol if the default metrics are used? F,E,D,C,A F,G,E,D,B,A F,E,D,B,A F,G,E,D,A F,E,D,A 29 A network administrator trying to deny Telnet traffic from the 192.5.5.0 network to the 201.100.11.0 network entered the commands shown in the graphic. When monitoring the network, the administrator noticed that the Telnet packets are still passing between those networks. What is the cause? The router ignored this type of traffic because it required a standard access list to be configured instead of an extended one. The wrong port was configured for the ACL so Telnet traffic was still allowed. The access list has not been assigned to an interface. The permit ip any any allowed all traffic to pass regardless of the other statements listed in this ACL. 30 Which of the following are true regarding the setup configuration mode? (Choose three.) To abort the setup mode, use the CTRL+SHIFT+6 keys. To abort the setup mode, use the CTRL+C keys. Setup mode allows a complete configuration of the router. To enter setup mode, use the privileged mode setup command. A router that does not find a valid IOS during the boot process will start he system configuration dialog. A router that does not find a valid configuration file during the boot process will start the system configuration dialog. 31 Refer to the above graphic. When using RIP as the routing protocol, how would Chicago use load balancing to route packets to New York? (Choose two.) by forwarding packets over paths of equal cost by forwarding packets according to hop count and speed of the link by determining which interface has the least traffic and sending to it first by first determining the speed of the links and then cycling packets through the fastest links first by cycling packets through interfaces and routes following the same pattern (Router 1, 2, 3) each time 32 Which of the following are characteristics of the Open Shortest Path First (OSPF) routing protocol? (Choose two.) functions as a link state routing protocol discards packets when the hop count is greater than 15 calculates the shortest path to a destination using the Diffused Update Algorithm (DUAL) created as a proprietary routing protocol floods routing updates as topology changes occur broadcasts routing updates every 90 seconds or as triggered by topology changes 33 Which of the following is true regarding the (PDU) shown in the graphic? It is a server response to a client request for It is a client request for Telnet services on a It is a server response to a client request for It is a client request for e-mail services on a protocol data unit Telnet services. server. e-mail services. server. 34 Which of the following are true regarding route metrics? (Choose three.) The more factors that make up a metric, the greater the flexibility to tailor network operations. The larger the metric number, the better the path. Routing protocols use metrics to send routing updates to directly connected neighbors. Load and reliability are dynamic metrics used by IGRP. Bandwidth and delay are static metrics used by RIP v1. Ticks delay, MTU, and cost are metrics used by routing protocols. 35 Routers have different types of memory. Choose the answer that describes ROM. provides working storage stores a fully functional IOS image stores the startup configuration file initializes the code used to boot the router 36 Which of the following would cause the "Message Of The Day" banner to appear? (Choose three.) telnetting into the router initiating a debug session configuring a router for the first time using the Aux port to check the current configuration using the console port to check the current configuration 37 RouterB loses connectivity to network 172.17.22.0. During the next update interval, RouterB sends an update to RouterA signifying that network 172.17.22.0 is inaccessible. RouterA adds the changes received from RouterB to its routing table. Approximately at the same time, RouterC sends an update to RouterA stating that network 172.17.22.0 is up. Which of the following is true regarding the described situation? (Choose two.) Router A will not accept the information from RouterC if split horizon is enabled. RouterA accepts the information and updates its routing table to prevent a routing loop. After receiving updates from RouterB and RouterC, RouterA will have two routes to network 172.17.22.0 in its routing table. A router can accept an additional update about a network from any device regardless of the original source of the update. RouterA will remove network 172.17.22.0 from its routing table if the network is inaccessible after the flush timer has expired. 38 Host name resolution allows for the use of an alphanumeric name to identify network devices. Select the answer that displays the correct configuration syntax for creating a host name. Router# ip host Fontana 200.100.50.5 Router(config)# ip host Fontana 200.100.50.5 Router(config-if)# ip host Fontana 200.100.50.5 Router(config)# ip host Fontana 200.100.50.5/24 39 How many Telnet sessions can take place simultaneously on a router running a standard edition of the IOS? 4 5 8 10 40 What are the major characteristics of a wide area network?

(Choose three.) Idaho(config)# ip route 172.31.1.0 255.255.255.0 172.31.2.1 Idaho(config)# ip route 0.0.0.0 0.0.0.0 s0 Idaho(config)# ip route 172.31.2.0 255.255.255.0 172.31.2.2 Utah(config)# ip route 172.31.3.0 255.255.255.0 172.31.2.1 Utah(config)# ip route 172.31.3.0 255.255.255.0 s1 Utah(config)# ip route 0.0.0.0 0.0.0.0 s0 43 The following line was displayed in the output of the show ip route command. I 192.168.3.0/24 [100/80135] via 192.168.2.2, 00:00:30, Serial0/0 What is the value of the composite metric? 8 24 80 100 135 80135 44 Which of the following are basic rules that should be followed when creating and applying access lists? (Choose three.) Access list entries should filter in the order from general to specific. One access list per protocol per direction. Standard ACLs should be applied closest to the source while extended ACLs hould be applied closest to the destination. There is an implicit deny at the end of all access lists. Statements are processed sequentially from top to bottom until a match is found. Use the inbound or outbound interface reference as if looking at the port from outside the router. 45 When must a router serial interface be configured with the clock rate command? when the interface is functioning as a DTE when the interface timers have been cleared when the connected DTE device is shut down it must always be configured on a serial interface when no other device is supplying a clock signal to the link 47 Which statement about datagram life is true? -Each router increments the TTL value of the datagram until the maximum hop count of the routing protocol is reached. -The packet is then returned to the source. -The packet is dropped when the router count and the TTL value match. The source is notified that transmission has failed. -Each router decreases the TTL value by one until it reaches zero. The datagram is then discarded and a destination unreachable message is sent to the source. -The destination device discards the datagram if the TTL value is zero on arrival. -An ICMP destination unreachable message is sent back to the source. 48 Refer to the output from the show ip route command. What can be concluded from the output of this router command? A preferred route to the destination has not been set. There are two equal cost paths to network 1.0.0.0. Both interfaces are being used equally to route traffic. A variance must be set to load-balance across multiple paths. 49 What can be determined from the partial output of the show ip route command displayed below? (Choose two.) R 200.200.200.0/24 [120/1] via 192.168.10.2, 00:00:14, Serial0/0 C 192.168.10.0/24 is directly connected, Serial0/0 The next update will be in 76 seconds. The next update will be in 16 seconds. The administrative distance is 120 and the metric is 1. The metric is 120 and the administrative distance is 1. 200.200.200.0 is configured on Serial0/0. 192.168.10.2 is configured on Serial0/0. 50 The host shown in the graphic has issued the ICMP request packet shown. What information does the host require, and which ICMP message should be sent in reply? (Choose two.) The host requires the default gateway MAC address. The host requires the default gateway IP address. The host requires a timestamp for synchronization. The reply should be a router solicitation message. The reply should be a router advertisement message. The reply should be a receive and transmit timestamp reply message. 51 The administrator knows that port E0 on router B connects to a small LAN without any routers. Which command can be executed on router B to conserve bandwidth on port E0? no update timers holdown-timer 96 poison reverse E0 passive -interface E0 no triggered updates 52 An administrator has made routing protocol changes to a router's configuration. To ensure that the changes are implemented, the active configuration is saved and the router is reloaded. After the router has initialized, the output on the screen displays "Would you like to enter the initial configuration dialog?[yes/no]:" Why did this dialog appear? There was a POST failure. The incorrect IOS loaded. There was an error in the startup configuration file. The configuration register was set to ignore NVRAM. Extra Which statement about datagram life is true? -Each router decreases the TTL value by one until it reaches zero. The datagram is then discarded and a destination unreachable message is sent to the source. Extra If the config-register on a router is set to 0x2102, where is the first place the router will look for boot system commands? -NVRAM
