第3题：

In the Ezonexam switched LAN environment, what does the IEEE 802.1Q standard describe?

A. VLAN pruning

B. A method of VLAN trunking

C. An approach to wireless LAN communication

D. The operation of VTP

E. The process for root bridge selection

F. None of the above


正确答案：B
B 解析：Explanation:
A broadcast domain must sometimes exist on more than one switch in the network. To accomplish this, one switch must send frames to another switch and indicate which VLAN a particular frame. belongs to. On Cisco switches, a trunk link is created to accomplish this VLAN identification. ISL and IEEE 802.1Q are different methods of putting a VLAN identifier in a Layer 2 frame.

The IEEE 802.1Q protocol interconnects VLANs between multiple switches, routers, and servers. With 802.1Q, a network administrator can define a VLAN topology to span multiple physical devices. Cisco switches support IEEE 802.1Q for FastEthernet and Gigabit Ethernet interfaces. An 802.1Q trunk link provides VLAN identification by adding a 4-byte tag to an Ethernet Frame. as it leaves a trunk port.
