Networking Concepts第 10 / 100 题
What is the primary purpose of a VLAN in a switched network?
a.To logically segment a physical switch into separate broadcast domains
b.To increase the speed of individual switch ports
c.To convert Layer 2 frames into Layer 3 packets
d.To provide power to connected devices
解析
A VLAN logically segments a switch so that ports belong to separate broadcast domains without needing additional physical switches. This improves security and reduces broadcast traffic. Routing between VLANs still requires a Layer 3 device.
