Explanation

Question 16 of 21

1

16. Which three statements are true about routes and their use? (Choose three.)

Select one or more of the following:

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.

Explanation

Question 17 of 21

1

Refer to the exhibit. A network administrator is troubleshooting a connectivity problem and needs to determine the address that is used to forward network packets out the 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.

1

21. What statement describes the purpose of a default route?

Select one or more of the following:

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.
