What is a characteristic of a VLAN?

The correct answer is A. associated with IP address subnetworks. A VLAN (Virtual LAN) is a logical Layer 2 segmentation that is associated with its own IP address subnetwork (subnet). Each VLAN is assigned a unique subnet, and inter-VLAN communication requires Layer 3 routing. Option B is incorrect because VLANs are logical, not physical…

Explanation

A VLAN (Virtual LAN) is a logical Layer 2 segmentation that is associated with its own IP address subnetwork (subnet). Each VLAN is assigned a unique subnet, and inter-VLAN communication requires Layer 3 routing. Option B is incorrect because VLANs are logical, not physical, segmentation-devices in the same VLAN can be on different physical switches. Option C is incorrect because users on different VLANs are isolated by default and cannot access each other's data without a router. Option D is incorrect because VLANs are mapped to IP subnets, not MAC address subnetworks-switches use MACs to forward frames within a VLAN, but the VLAN-to-subnet association is IP-based.
