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.
*A router that does not find a valid configuration file during the boot process will start the system configuration dialog.
22
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.
23
Assume OSPF is being used on all routers. What happens when the link between Router1 and Router2 goes down? (Choose two.)

*Ticks, delay, and cost are metrics used by routing protocols.

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.
