TCP/UDP
An application uses UDP to send 7000 bytes of data in a single message on a path with MTU = 1500 and there is an error in one of the fragments transmitted. The application is a reliable application and so retransmits the 7000B again. How much more data is transmitted by this ... ? 1) 5588 2) 5584 3) 5580 4) 5496 none of the answers are matching for me I am getting 5520 maybe I am wrong
