10 When the destination network is not listed in the routing table of a Cisco router, what
are two possible actions that the router might take? (Choose two.)
The router sends an ARP request to determine the required next hop address.
**The router discards the packet.
The router forwards the packet toward the next hop indicated in the ARP table.
The router forwards the packet to the interface indicated by the source address.
**The router forwards the packet out the interface indicated by the default route entry.
11 What are the key factors to consider when grouping hosts into a common network?
(Choose three.)
gateways
**purpose
physical addressing
software version
**geographic location
**ownership
**router
hub
switch
**firewall
access point
bridge

16 Which three statements are true about routes and their use? (Choose three.)
If no route to the destination network is found, the packet is returned to the previous
router.
**If the destination network is directly connected, the router forwards the packet to the
destination host.
If multiple network entries exist for the destination network, the most general route is
used to forward the packet.
**If no route exists for the destination network and a default route is present, the packet
is forwarded to the next-hop router.
**If the originating host has a default gateway configured, the packet for a remote
network can be forwarded using that route.
If a host does not have a route manually configured for the destination network, the host
will drop the packet.

Refer to the exhibit. The network in the exhibit is fully operational. What two statements
correctly describe the routing for the topology that is shown? (Choose two.)
**192.168.0.2 is the next-hop address that is used by R3 to route a packet from the
10.0.0.0 network to the 172.16.0.0 network.
10.0.0.1 is the next-hop address that is used by R1 to route a packet from the
192.168.12.0 network to the 10.0.0.0 network.
192.168.0.1 is the next-hop address that is used by R1 to route a packet from the
192.168.12.0 network to the 172.16.0.0 network.
172.16.0.1 is the next-hop address that is used by R3 to route a packet from the 10.0.0.0
to the 172.16.0.0 network.
**192.168.0.1 is the next-hop address that is used by R2 to route a packet from the
172.16.0.0 network to the 192.168.12.0 network.
192.168.0.2 is the next-hop address that is used by R2 to route a packet from the
172.16.0.0 network to the 192.168.12.0 network.
20 What two characteristics are commonly associated with dynamic routing protocols?
(Choose two.)
A host uses a default route to transfer data to another host on the same network segment.
A host uses a default route to forward data to the local switch as the next hop to all
destinations.
A host uses a default route to identify the Layer 2 address of an end device on the local
network.
**A host uses a default route to transfer data to a host outside the local network when no
other route to the destination exists.
