Given that ge-0/1/1 is set up as a trunk port, which command set will NOT successfully set the trunk to carry VLANs 10 and 11?

The command set that would not successfully configure the trunk port to carry VLANs 10 and 11 is the one that incorrectly specifies the VLANs as a single entity, using a comma without clear separation. In this case, the correct syntax for adding VLANs to an interface in a Junos environment requires either a space or the keyword 'members' to designate multiple VLANs.

In option C, the command uses a comma to separate the VLANs: "set interfaces ge-0/1/1.0 family ethernet-switching vlan members Vlan10,Vlan11." This syntax does not conform to the valid command structure expected by the Junos OS. Instead of simply listing VLANs with a comma, the command structure needs to maintain clarity in delineating the VLANs as separate entities.

Successful configurations in Junos typically require a syntax such as "set interfaces ge-0/1/1.0 family ethernet-switching vlan members [Vlan10 Vlan11]" or similar guidelines that clearly indicate each VLAN without ambiguity. This attention to syntax detail ensures that the device accurately infers the list of VLANs intended for the trunk port. Therefore, it is this incorrect use of commas that leads to option C being the one
