Which of the following statements accurately describes VLANs?

The correct answer is A. They are not restricted to the same data center or the same racks. VLANs (Virtual Local Area Networks) are logical network segments defined in software, not hardware.

Explanation

VLANs (Virtual Local Area Networks) are logical network segments defined in software, not hardware. Because they operate at Layer 2 using tagging (e.g., IEEE 802.1Q), they are not tied to any physical boundary - they can span multiple racks, multiple switches, and even multiple data centers connected via trunk links or VLAN-aware routing. This flexibility is one of their primary advantages over traditional physical network segmentation.
