What are some characteristics of the typical VLAN arrangement?

A. VLANs logically divide a switch into multiple, independent switches at Layer 2.
B. Trunk links can carry traffic for multiple VLANs.
C. VLAN implementation significantly increases traffic due to added trunking
information.
D. A VLAN can span multiple switches.
E. VLANs extend the collision domain to include multiple switches.
F. VLANs typically decrease the number of multiple switches.

Answer: A, B, D


Explanation:

VLANs give you the power of making virtual LAN networks to subdivide collision
domains into smaller units of functionality. Without being limited by physical location.
A is correct because that is the exact function of a VLAN. B is correct because trunk links
are used to carry traffic for multiple VLANs. D is correct because a VLAN can and often
does span across multiple switches, through the use of VTP


Incorrect Answers:
C. This choice is incorrect because although trunking information uses bandwidth, the
amount isn't at all significant.
E. This is incorrect because VLANs do the exact opposite, and are used to segment
collision domains.
F. This is incorrect because VLANs themselves have no power in decreasing the numbers
of multiple switches.
