If SW1 G0/0 is set to dynamic desirable and SW2 G0/0 is set to static access, what will be the operational mode of SW1 G0/0?

In this scenario, SW1's G0/0 port is configured as "dynamic desirable," while SW2's G0/0 port is set to "static access." When dealing with switch port configurations, especially in relation to VLAN trunking, it’s important to understand how these modes interact.

When a port is set to "dynamic desirable," it indicates that the switch port is actively attempting to form a trunk link. It will negotiate with the other switch to reach a trunking state, utilizing Dynamic Trunking Protocol (DTP). On the other hand, a port configured as "static access" does not participate in trunk negotiations and will specifically only allow traffic on a single VLAN (the default VLAN 1 unless changed).

In this situation, since SW2's G0/0 port is in static access mode, it effectively indicates that this port is not capable of establishing a trunk link. Hence, SW1's G0/0 will recognize that the other end (SW2 G0/0) is not set to trunk and will revert to identifying the link as an access link.

As a result, SW1's G0/0 will operate in "static access" mode, corresponding to the single VLAN configuration set on
