Which of the following statements about the "S" field in the MPLS packet header are true? (Choose all that apply.)
The 'S' field in the MPLS packet header is 1 bit long and indicates whether there are additional labels in the stack. When the value is 0, it means there are other labels following the current label, and when the value is 1, it signifies that this is the last label in the stack. Hence, option A is incorrect, while option C is correct. The 'S' field indeed exists in each MPLS packet header, making option D correct.
