giải thích VLAN như vậy tốt nhất chưa?
Dear all.
I saw this question. "640-802 v13, page 189, question 4"
What are some of the characteristics of a typical VLAN arrangement, found
throughout the Tes tKing switched LAN? (Select all that apply)
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 typically increase the number of switches needed
F. VLANs typically decrease the number of switches needed
Answer: A, B, D
Incorrect Answers:
C. Although trunking information does indeed add some level of overhead, the overall
traffic overhead is greatly reduced though the use of VLANs.
I don't understand this expanation, Why this question "C" is wrong? If someone know, please explain to me. And better show me which document and which page tell about this thing clearly?
I'm expecting for your reply
Your sincerely
