QUESTION 28
Which three modes are the operating of HDLC? (Choose three)
A. asynchronous balanced mode (ABM)
B. normal response mode (NRM)
C. normal peer mode (NPM)
D. asynchronous client mode (ACM)
E. asynchronous response mode (ARM)
Answer: ABE
Explanation:
Asynchronous response mode is an HDLC addition[1] for use over full-duplex links. While retaining the primary/secondary distinction, it allows the secondary to transmit at any time. Asynchronous balanced mode added the concept of a combined terminal which can act as both a primary and a secondary. There are some subtleties about this mode of operation; while many features of the protocol do not care whether they are in a command or response frame, some do, and the address field of a received frame must be examined to determine whether it contains a command (the address received is ours) or a response (the address received is that of the other terminal).
QUESTION 29

A. path attributes
