What is the role of a switchport in trunk mode?

When a switchport is configured in trunk mode, its primary role is to carry traffic for multiple VLANs (Virtual Local Area Networks) across a single link. This capability is essential in scenarios where multiple VLANs need to communicate between switches.

In trunk mode, the port is specifically set up to handle traffic from various VLANs, using tagging protocols like 802.1Q to differentiate between traffic from the different VLANs. The option indicating that the trunk is statically formed and no Dynamic Trunking Protocol (DTP) frames are sent correctly identifies that in a configured trunk port, the link is established without the negotiation process that DTP provides. DTP is used for automatic trunk formation, but when a port is statically set to trunk mode, it does not listen for DTP frame requests or engage in DTP negotiation; instead, it proactively transmits and receives traffic for all configured VLANs based on its trunk configuration.

This characteristic of operating independently from DTP makes the configuration reliable in environments where it's crucial to ensure that trunk links are consistently established without the possibility of a misconfiguration that could occur if relying purely on dynamic negotiation. Thus, the correct answer highlights the nature and function of the trunk port in maintaining a clear and
