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.

25	The commands shown in the graphic were entered to alter the startup sequence of the router. On the next reload, which IOS will be loaded? The router will load c2500-js-l.112-26d. 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.

30	ACL statements operate in sequential, logical order. If a condition match is true, the rest of the ACL statements are not checked. 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. A router that does not find a valid IOS during the boot process will start the system configuration dialog.
