Explanation

VLAN trunking (B) is the correct term because a trunk port carries traffic from multiple VLANs simultaneously between switches or between a switch and a router, using tagging (typically IEEE 802.1Q) to distinguish which frames belong to which VLAN.

Why the distractors are wrong:

• A (VLAN riding) - not a real networking term; it's fabricated.
• C (Frame-Strata enabled) - completely fictional; no such protocol or concept exists in networking.
• D & E (Comprehensive Layer-2 label support / Comprehensive VLAN Tag support) - also invented terms designed to sound plausible by referencing real concepts (Layer 2, VLAN tags) without being actual standards or terminology.

Memory tip: Think of a trunk on a tree - one trunk carries water and nutrients to many branches, just as one trunk port carries traffic for many VLANs. The word "trunk" implies carrying multiple things through a single channel.
