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

A.
to make VTP easier to implement

B.
to isolate broadcast traffic

C.
to increase the size of the collision domain

D.
to allow more devices to connect to the network

E.
to logically group hosts according to function

F.
to increase network security

Explanation:
VLAN has the following advantages:
1. Restrict broadcast domain. That is to say each VLAN is a Broadcast domain, which saves
bandwidth and improves the network performance.
2. Enhance the LAN security. Datagrams in different VLANs transmit separately, that is to say
users in one VLAN can’t directly communicate with users in other VLANs, if they want to
communicate, devices such as routers and layer3 switches are required.
3. Establish a virtual working group flexibly. VLAN can group different users into different working
team regardless of their physical location, which makes network establishment and maintenance
more flexible.
