Which trunking standard is widely used as an open standard for trunks?

Explanation:
VLAN trunking across switches is standardized by 802.1Q, which defines how frames are tagged with VLAN IDs so a single physical link can carry traffic for multiple VLANs while keeping them separate inside devices. This open, vendor-neutral tagging method is widely adopted, making it the common choice for trunks. Other standards focus on different areas: one defines how multiple physical links can be combined for higher throughput (link aggregation), another is a wireless networking standard, and another governs loop prevention in switching.
