Question

(a) Persistent

(b) Non-persistent

(c) Can be either persistent or non-persistent depending on connection request

(d) None of the mentioned

The question was posed to me in an internship interview.

My query is from HTTP in section Application Layer of Computer Network

Answer 1

Correct option is (a) Persistent

To explain: By default the http connection is issued with persistent connection. In persistent connection server leaves connection open after sending response. As little as one RTT (Time for a small packet to travel from client to server and back) is required for all referenced objects.
