A. by encrypting passwords in the plain text configuration file B. by requiring entry of encrypted passwords for access to the device C. by automatically suggesting encrypted passwords for use in configuring the router D. by configuring an MD5 encrypted key to be used by routing protocols to validate routing exchanges Correct Answer: A QUESTION 196 You work as a network administrator for the P4S Ltd. Study the exhibit carefully. The company's internetwork is

116 displayed in the exhibit. You want to reduce the size of the routing table on the Central router. Which partial routing table entry in the Central router represents a route summary that represents the LANs in Phoenix but no additional subnets? A /28 is subnetted, 1 subnets D [90/ ] via , 6w0d, Serial0/1 B /28 is subnetted, 1 subnets D [90/ ] via , 6w0d, Serial0/1 C /30 is subnetted, 1 subnets D [90/ ] via , 6w0d, Serial0/1 D /22 is subnetted, 1 subnets D [90/ ] via , 6w0d, Serial0/1 Correct Answer: D QUESTION 197 The network administrator of the P4S1 router adds the following command to the router configuration: ip route What are the results of adding this command?(choose two)

117 A. Traffic for network is forwarded to B. This route is automatically propagated throughout the entire network. C. Traffic for all networks is forwarded to D. The command establishes a static route. Correct Answer: AD QUESTION 198 You are a network technician at P4S,study the exhibit carefully. Users on the Holyoke router can't access the intranet server attached to interface E0 of the Chicopee router. Inspection of the routing table of the Holyoke router displays that an entry for the Chicopee E0 network is missing. In order to configure the Holyoke router with a path to the intranet server network, which command will you use? A. Holyoke(config)# ip route B. Holyoke(config)# ip network C. Holyoke(config)# ip network

118 D. Holyoke(config)# ip route Correct Answer: D QUESTION 199 Match the correct relationship between the term and its definition. 1.holddown timer 2.poison reverse 3.count to infinity 4.LSA 5.split horizon A. A router learns from its neighbor that a route is down, and the router sends an update back to the neighbor with an infinite metric to that route. II.The packets flooded when a topology change occurs, causing network routers to update their topological databases and recalculate routes. III. This prevents sending information about a route back out the same interface that originally learned about the route. IV.For a given period, this causes the router to ignore any updates with poorer metric to a lost network. B. I-1,II-3,III-2,IV-4 C. I-2,II-4,III-5,IV-1 D. I-1,II-4,III-5,IV-3 E. I-2,II-3,III-1,IV-4 Correct Answer: B QUESTION 200 You are a technician for P4S. The configurations in the following exhibit are pasted into the two new routers shown. Otherwise, the routers will be configured with their default configurations. Host P4S-PC1 cannot ping Host P4S-PC2, but you can ping the S0/0 interface of P4S-R2 from Host P4S-PC1. You have verified the configurations of the hosts and they are correct. What is the cause of the problem?

119 A. The serial cable on P4S-R1 should be replaced. B. P4S-1 has no route to the network. C. The interfaces on P4S-R2 are not configured properly. D. The ip subnet-zero command must be configured on both routers. Correct Answer: B /Reference:
