Refer to the exhibit. A network administrator configures an interface on a new switch so that it connects to interface Gi1/0/1 on switch Cat9300-1. Which configuration must be applied to the new inter

The `switchport mode trunk` command explicitly configures the interface as a trunk port, which is the standard configuration for inter-switch links to carry traffic for multiple VLANs.

The `switchport mode dynamic desirable` command attempts to negotiate a trunk using DTP (Dynamic Trunking Protocol), which is less explicit and might lead to unexpected behavior if the other side is not configured appropriately or if DTP is disabled.

The `switchport trunk encapsulation dot1q` command specifies the trunking protocol and is often required before setting the `switchport mode trunk` on older switches, but it's not the primary mode configuration for enabling a trunk on a new interface.

The `switchport nonegotiate` command disables DTP and is typically used when a trunk is statically configured with `switchport mode trunk`, but it does not define the trunk mode itself.
