What best describes a trunk link in a VLAN-configured switch environment?

Explanation:
A trunk link is about carrying traffic for multiple VLANs over one physical connection by tagging each frame with its VLAN identifier. This tagging, typically 802.1Q, lets switches on either end know which VLAN the frame belongs to as it traverses the link, so multiple VLANs can share a single cable. In contrast, an access port sends and receives traffic for just one VLAN (untagged or tagged only for that VLAN), so it wouldn’t be described as carrying multiple VLANs. Trunking doesn’t inherently block traffic or encrypt it; its purpose is VLAN separation and transport across a single link.
