Refer to the exhibit. Which command must be executed for Gi1.1 on SW1 to become a trunk port if Gi1/1 on SW2 is configured in desirable or trunk mode?

While `switchport mode trunk` would force a trunk, the question asks for a command given SW2 is dynamic/trunk, implying DTP negotiation where `dynamic auto` is a suitable response.

`switchport mode dot1-tunnel` configures a QinQ tunnel port, which is not for standard 802.1Q trunking.

When the neighboring switch port (SW2 Gi1/1) is configured in either `switchport mode dynamic desirable` or `switchport mode trunk`, configuring SW1 Gi1/1 with `switchport mode dynamic auto` will successfully negotiate and establish a trunk link. The `dynamic auto` mode makes the port willing to convert to a trunk link if the adjacent port actively desires or forces a trunk.

`switchport mode dynamic desirable` would also result in a trunk, but `dynamic auto` is also a valid and often preferred passive option when the other side is already actively attempting to form a trunk or forced into trunk mode.
