Explanation

VLAN trunking (E) is the correct term because a trunk port carries traffic from multiple VLANs simultaneously over a single physical link, using tagging protocols like IEEE 802.1Q to identify which VLAN each frame belongs to. This is standard networking terminology used across Cisco, CompTIA, and vendor-neutral certifications.

Why the distractors are wrong:

• A (Comprehensive VLAN tag support) and D (Comprehensive Layer-2 label support) are fabricated phrases that sound technical but don't correspond to any real networking standard or concept.
• B (VLAN riding) is not a recognized term in networking - nothing "rides" a VLAN in formal terminology.
• C (Frame-Strata enabled) is completely made up; no such protocol or feature exists.

Memory tip: Think of a trunk as a tree trunk - just as a single trunk supports many branches, a trunk port carries traffic from many VLANs over one link. The word "trunk" = "multiple things bundled together."
