21	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 time exceeded for 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.
22	The following access list has been created to prevent traffic from host 204.204.7.122 from accessing the 201.100.11.0 network. access-list 22 deny host 204.204.7.122 access-list 22 permit any Which group of commands will properly place this access list so that this host is denied access only to the 201.100.11.0 network?

The router will load c2500-d-l.120-9. The router will load the IOS from ROM. The router will boot into ROM monitor mode.
26	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 Telnet packets were 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.
27	Refer to the network graphic. A packet needs to travel from Router F to Router A. Which path would be selected by the RIP routing protocol if the default metrics are used? F, G, E, D, B, A F, E, D, C, A F, E, D, A F, E, D, B, A

If all of the ACL statements are unmatched, what happens to the packet? The packets will be placed in a buffer and forwarded when the ACL is removed. The packets will be sent to the source with an error notification message. The implicit permit any statement placed at the end of the list will allow the packets to flow through uninhibited. The implicit deny any statement placed at the end of the list will cause the packets to be dropped.

41	Which of the following are true statements about creating and applying access lists? (Choose three.) Access list entries should filter in the order from general to specific. One access list per port per protocol per direction is permitted. Standard ACLs should be applied closest to the source while extended ACLs should 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. The inbound keyword refers to traffic entering the network from the router interface where the ACL is applied.
42	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.

43	Which of the following are necessary for basic network communication to occur between hosts that will run such applications as Telnet, web browsers, and e-mail? (Choose three.) TCP/IP must be installed and properly configured on each device. Multiple subnets must be configured on the router to ensure accurate delivery. A default gateway must be configured for datagrams to travel outside of the LAN. The hosts must be directly connected to a switch to travel outside of the LAN. To ensure accurate delivery, a router must be configured and accessible by hosts on the network.

However, when the workstation on network 172.29.5.0/24 sends a packet to destination address 172.29.198.5, it is discarded by the Suffolk router. What can be a reason 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 172.29.198.0/24 network 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.
