Question

Choose the correct statement from the following.

(a) PPP can terminate the link at any time

(b) PPP can terminate the link only during the link establishment phase

(c) PPP can terminate the link during the authentication phase

(d) PPP can terminate the link during the callback control phase

This question was addressed to me in semester exam.

The doubt is from PPP topic in section Point to Point Protocol & Error Detection of Computer Network

Answer 1

Right option is (a) PPP can terminate the link at any time

For explanation I would say: PPP allows termination of the link at any time in any phase because it works on the data link layer which is the layer in control of the link of the communication.
