If a unit is actively involved in a call, how is its status updated via the command line?

The correct response, which involves the command line syntax necessary for updating a unit’s status, appropriately reflects the specific format required by the system. The notation “UU Unit# SC.C4” signifies a command to change the unit's status to indicate it is actively involved in a call.

The “UU” prefix is critical because it typically stands for “Unit Update,” indicating that this command is intended for updating the status of a unit. Following that, “Unit#” specifies which unit is being updated, and “SC.C4” likely represents a specific code that denotes the status change to reflect engagement with a call.

Other options do not adhere to the required format of providing an update in the command line. They largely resemble status codes or identifiers but lack the specific prefix or structure needed for a status update command, thus making them unsuitable for this context. This emphasizes the importance of using the correct command structure to ensure that statuses are logged and updated appropriately in the system.
