A. B. C. D.D.
The Cisco Dynamic Trunking Protocol (DTP) is a proprietary protocol used to negotiate and manage trunk links between Cisco switches. When two switches are connected and DTP is enabled, they will attempt to negotiate the link's operational mode, which can be one of the following:
Dynamic Auto (DA): The switch port will wait for the other end to initiate DTP negotiation. If the other end is set to Dynamic Desirable or Trunk, the port will become a trunk port. Otherwise, it will become an access port.
Dynamic Desirable (DD): The switch port will actively attempt to initiate DTP negotiation and request that the other end becomes a trunk port. If the other end is set to Dynamic Auto or Trunk, the port will become a trunk port. Otherwise, it will become an access port.
Trunk: The switch port is explicitly configured to be a trunk port and will not participate in DTP negotiation.
Access: The switch port is explicitly configured to be an access port and will not participate in DTP negotiation.
In this scenario, SW1 is set to Dynamic Auto and SW2 is set to Dynamic Desirable. As a result, SW2 will initiate DTP negotiation and request that SW1 becomes a trunk port. Since SW1 is set to Dynamic Auto, it will accept the request and become a trunk port.
Therefore, the correct answer is D. The link becomes a trunk port.
