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
