Final answer:
G1/1 is not in the default VLAN when configured as trunk mode.
Step-by-step explanation:
The statement is B) False.
If G1/1 is configured as trunk mode, it will not be in the default VLAN. Trunk mode allows for the transmission of multiple VLANs over a single link, while access mode assigns a specific VLAN to a link. By default, G1/1 would be in access mode, and therefore, in the default VLAN.
For example, if G1/1 is configured as trunk mode and assigned to VLAN 10, it will be part of VLAN 10, not the default VLAN
