What command is used to update a specific zone via CMD line?

The command B is used to update a specific zone via the command line due to its structure, which clearly identifies the unit and the zone that needs to be updated. The format "UZ Unit# Zone" effectively isolates the parameters, where "Unit#" indicates which unit is being referenced, and "Zone" specifies the target zone for the update.

This clarity in the command format allows for straightforward updates without ambiguity, ensuring that the correct unit is associated with the correct zone. Utilizing distinct parameters contributes to operational efficiency and minimizes the risk of errors during command execution. It’s crucial that commands in operational settings maintain a level of simplicity and direct correlation to their intended effects, which this command upholds.

The other options include commands that may pertain to other functions or follow different syntax patterns that don’t specifically focus on zone updates, making them less relevant in the context of the question regarding zone updating.
