1616. Which three statements are true about routes and their use? (Choose three.)

- CIf multiple network entries exist for the destination network, the most general route is used to forward the packet.
- DIf no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router.
- EIf the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
- FIf a host does not have a route manually configured for the destination network, the host will drop the packet.
- AIf no route to the destination network is found, the packet is returned to the previous router.
17Refer 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.
