Answer: 12
Explanation:
During requesting the web page with the 10 reference objects, total 12 RTTs are need for the persistent connection.
As, For handshake it require total 1 RTT and for the web page also 1 RTT required. Then, for each 10 referenced object it require total 10 RTTs.
Therefore, after adding all the RTTs = 12 RTTs required.
The persistent connection are used for reduced the network congestion and transfer the data to the end user. By using this connection we can easily find put the total reference object without any error occur during the connection.
