| Question 10 |
The LAPB frame structure and the frame structure of SDLC are :
| Opposite | |
| Identical | |
| Reversed | |
| Non-identical |
Question 10 Explanation:
Link Access Procedure, Balanced (LAPB) implements the data link layer as defined in the X.25 protocol suite. LAPB is a bit-oriented protocol derived from HDLC that ensures that frames are error free and in the correct sequence.
Frame format:
*** The LAPB frame structure and the frame structure of SDLC are identical.
Frame format:
*** The LAPB frame structure and the frame structure of SDLC are identical.
Correct Answer: B
