In a typical data network, there are usually several IP subnets. What level of devices are required to exchange data between these IP subnets?

• 1

• 2

• 3

• 4

Routing is the basic element of data communication networks. It is the process of _______ on a network along which packets are sent from a source to a destination.

• selecting paths

• making connections

• picking options

• routing capabilities

To implement IP addressing, subnets in different areas need to _______ with each other.

• connect

• communicate

• contact

• constitute

______ are the path information used to guide packet forwarding.

• Guides

• Protocols

• Maps

• Routes

A routing device maintains an IP routing table that stores routing information.

• true

• false

What identifies a destination subnet?

• destination

• subnet mask

• next hop

• interface

• What identifies a subnet together with a destination IP address?

• destination

• mask

• interface

• next hop

Which interface indicates the interface through which a data packet is sent out of the local router.

• outbound

• inbound

Next hop: indicates the next-hop address used by the router to forward the data packet to the destination subnet.

• true

• false

A router forwards packets based on its IP routing table. To implement route-based packet forwarding:

• the router needs to send routes

• the router needs to obtain routes

• the router should obtain routes

• the router needs to sell routes
