What will be the operational mode if SW1 G0/0 is dynamic auto and SW2 G0/0 is dynamic auto?

In the given scenario, both switches SW1 and SW2 have their Gigabit Ethernet interfaces configured as dynamic auto. When both ends of a link are set to dynamic auto, they are capable of negotiating trunking settings using the Dynamic Trunking Protocol (DTP).

However, when both interfaces are set to dynamic auto, they will not initiate the negotiation for trunking. Instead, they will both remain in a state where they can only form an access link, because neither side is actively trying to negotiate a trunk. This leads to the conclusion that the operational mode will result in a static access link, as no trunking will be established between the two interfaces.

On the other hand, options like trunk or dynamic access would require at least one side to be set as dynamic desirable or trunk, which is not the case here. The down state occurs when there is no physical connectivity or if the interface is administratively shut down. Since the interfaces are operationally up but not negotiating a trunk link, the correct outcome is a static access link.
