29 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 the Telnet packets are 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 Which of the following are true regarding the setup configuration
mode? (Choose three.)

system configuration
dialog.
A router that does not find a valid configuration file during the boot process
will start the system configuration dialog.

protocol, how would Chicago use load balancing to route packets to
New York? (Choose two.)
by forwarding packets over paths of equal cost
by forwarding packets according to hop count and speed of the link
by determining which interface has the least traffic and sending to it first
by first determining the speed of the links and then cycling packets through the
fastest links first
by cycling packets through interfaces and routes following the same pattern
(Router 1, 2, 3) each time
32 Which of the following are characteristics of the Open Shortest
Path First (OSPF) routing protocol? (Choose two.)

server.
34 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, MTU, and cost are metrics used by routing protocols.

37 RouterB loses connectivity to network 172.17.22.0. During the
next update interval, RouterB sends an update to RouterA signifying
that network 172.17.22.0 is inaccessible. RouterA adds the changes
received from RouterB to its routing table. Approximately at the
same time, RouterC sends an update to RouterA stating that network
172.17.22.0 is up. Which of the following is true regarding the
described situation? (Choose two.)
Router A will not accept the information from RouterC if split horizon is
enabled.
RouterA accepts the information and updates its routing table to prevent a
routing loop.
After receiving updates from RouterB and RouterC, RouterA will have two routes
to network
172.17.22.0 in its routing table.
A router can accept an additional update about a network from any device
regardless of the original
source of the update.
RouterA will remove network 172.17.22.0 from its routing table if the network is
inaccessible after the flush timer has expired.

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.
