Question

Routers:

a. require more management than switches
b. are not susceptible to time delays
c. use data link layer addresses to move packets that leave the subnet
d. require only a few set of TCP/IP addresses
e. don't need much time to establish separate subnet addresses for each LAN

Answer 1

c. use data link layer addresses to move packets that leave the subnet

Step-by-step explanation:

To fully understand this answer you must first know what a router is and it s function.

A router is basically a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, a place where two or more networks connect.

LAN - Local Area Network

WAN - Wide Area Network

ISP - Internet Service Provider

A Router uses a data link as a way for connecting to a location in order to receive and send digital information.

Data transfer happens over a certain link protocol that allows data to be transferred securely from the source to the destination.

In the OSI model, data link makes up the second layer. It offers procedures and functions for the transfer of data and can also correct errors that occur in the physical layer.

A subnet is basically a logical subdivision of an IP network.

Let's put it all together:

A Router uses data link layer addresses to move packets that leave the subnet.

Answer 2

c. use data link layer addresses to move packets that leave the subnet

Step-by-step explanation:

The router interconnects network segments or entire networks. It passes data packets between networks based on the information of the network layer. The router makes logical decisions regarding the best route for sending data through an interconnected network and then directs the packets to the appropriate segment and output port. Their decisions are based on various parameters. One of the most important is to decide the address of the network to which the packet is destined.
