What are three valid reasons to assign ports to VLANs on a switch? (Choose three.)

A.
to increase the size of the collision domain

B.
to make VTP easier to implement

C.
to logically group hosts according to function

D.
to allow more devices to connect to the network

E.
to isolate broadcast traffic

F.
to increase network security

Explanation:
Main Functions of a VLAN (see previous question): The VLAN can group several broadcast
domains into multiple logical subnets. You can accomplish network additions, moves, and
changes by configuring a port into the appropriate VLAN. You can place a group of users who
need high security into a VLAN so that no users outside f the VLAN can communicate with them.
As a logical grouping of users by function, VLANs can be considered independent from heir
physical or geographic locations. VLANs can enhance network security. VLANs increase the
number of broadcast domains while decreasing their size.
