Which three statements are TRUE regarding a Local Area Network (LAN)? (Choose three.)

A.
A LAN is confined to one building or campus.

B.
A LAN can cover great distances.

C.
A LAN provides fast data transmission.

D.
A LAN is easily expandable.

E.
LANs require the use of a router to communicate between local hosts.

Explanation:
A LAN is confined to one building or campus, provides fast data transmission, and is easily expandable. A LAN
refers to the interconnection of computers within a building or a group of buildings. A LAN generally uses
twisted pair cables for data transmission.
The following are some characteristics of LANs:
LANs are generally confined to a building, a group of buildings, or a campus.
Every computer in the LAN can communicate with every other computer on the network.
A LAN is easy to set up, as physical connectivity can be easily established.
The cost of the transmission medium used is low, as a LAN generally uses CAT5, CAT5e, or CAT6 cables
for data transmission.
A LAN provides fast data transmission rates.
The option stating that a LAN can cover great distances is incorrect. A Wide Area Network (WAN) is a network
that does not have any geographical boundaries. The Internet is the best example of a WAN.
LANs do not require the use of a router to communicate (although they can be used to connect subnets)
between local hosts. Hosts can communicate through a hub or switch.
