Q Tagging is also known as?

Explanation:
Q tagging refers to marking Ethernet frames to show their VLAN membership. This is done with 802.1Q, which inserts a 4-byte VLAN tag into the frame between the MAC header and the EtherType field. The tag starts with a TPID of 0x8100 and includes the Tag Control Information, which carries the VLAN ID and priority bits. The term comes from the IEEE 802.1Q standard, where the tag is often called a Q-tag. This tagging lets switches carry multiple VLANs over a single physical link (trunking) while keeping traffic separated by VLAN. Other options aren’t standard terms for this concept: frame tagging isn’t the usual name for VLAN tagging, IP tagging would imply tagging at the IP layer, and port tagging isn’t a recognized mechanism for VLAN identification.
