A network administrator is connecting two Layer 2 switches in a network. These switches must transfer data in multiple networks. Which of the following would fulfill this requirement?
B. 802.1Q tagging
Explanation:
802.1Q tagging is the standard method used to enable VLAN (Virtual Local Area Network) tagging on a switch-to-switch link. This allows multiple VLANs to be transmitted over a single physical connection by tagging Ethernet frames with VLAN information. This is essential for transferring data across multiple networks between Layer 2 switches
The correct answer is:
B. 802.1Q tagging
Explanation:
802.1Q tagging is a standard for VLAN tagging on Ethernet frames, which allows Layer 2 switches to transfer data for multiple VLANs across a single trunk link. When switches are connected using 802.1Q tagging, they can handle traffic from different VLANs by adding a VLAN tag to each Ethernet frame. This ensures that data for multiple networks (VLANs) is properly identified and routed across the trunk connection.
