,Question
Refer to the exhibit. Match the packets with their destination IP address to the
exiting interfaces on the router. (Not all targets are used.)
Why: The router uses the most specific matching route. The first, second, third, and fifth
destinations match listed /24 routes; 172.17.8.20 has no specific route and therefore uses the
default route through Serial0/0/0.

,Question
Which parameter does the router use to choose the path to the destination
when there are multiple routes available?
✓ the lower metric value that is associated with the destination network
A.
○ the higher gateway IP address to get to the destination network
B.
○ the higher metric value that is associated with the destination network
C.
○ the lower gateway IP address to get to the destination network
D.
Why: When multiple routes are learned by the same routing protocol, the route with the lowest
metric is preferred.

, Question
Within a production network, what is the purpose of configuring a switch with a
default gateway address?
○ Hosts that are connected to the switch can use the switch default gateway address to
A. forward packets to a remote destination.
○ It provides a next-hop address for all traffic that flows through the switch.
B.
○ A switch must have a default gateway to be accessible by Telnet and SSH.
C.
✓ The default gateway address is used to forward packets originating from the
D. switch to remote networks.
Why: A Layer 2 switch uses its default gateway only for traffic generated by the switch itself,
such as remote-management traffic destined for another network.
