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. |

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. |
|
|
|
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. |

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 and cost are metrics used by routing protocols. |
