QUESTION 187
Which of the following statements are TRUE about VLAN?
A. VLAN technology allows a physical LAN to be divided into multiple physical LANs. Each VLAN functions as a separate broadcast domain, with hosts in the same VLAN able to directly communicate with one another, while those in different VLANs cannot.
