Suppose that a webpage consist of an index page plus four referenced objects. Three of these referenced objects reside on the same server while one object is to be fetched from a different server. Assume that TCP connection establishment takes

$1$ RTT$,$ that one object fits in a TCP segment, and ignore both object transmission time and TCP connection tear$-$down time.

How many RTTs the client will have to wait to see all objects on the page if it uses persistent HTTP without pipelining?

Select one alternative:

$7$
