Answer:
RST
Explanation:
What is RST TCP?
In a stream of packets of a TCP connection, each packet contains a TCP header. Each of these headers contains a bit known as the "reset" (RST) flag. ... One common application is the scenario where a computer (computer A) crashes while a TCP connection is in progress.
Why TCP RST is sent?
RST is sent by the side doing the active close because it is the side which sends the last ACK. So if it receives FIN from the side doing the passive close in a wrong state, it sends a RST packet which indicates other side that an error has occured.
The Transmission Control Protocol (TCP) flag which will be used when one side of a TCP connection hasn't been able to recover properly from a series of malformed segments is: C. RST.
In Computer networking, the transmission control protocol/Internet protocol (TCP/IP) model is a standard networking protocol that allows network devices and host computers to interconnect and communicate with each other over a network, especially through the transmission of data packets on either a wired or wireless connection.
Thus, a Transmission Control Protocol (TCP) is typically designed to allow network devices and software programs (applications) exchange messages over a network.
In a TCP connection, some of the functions of a flag include:
Furthermore, RST is an abbreviation for RESET in a TCP connection and it is used to instruct the receiver to stop communicating and as such the whole transmission of messages is stopped.
In conclusion, a RST flag would be used when one side of a TCP connection hasn't been able to recover properly from a series of malformed segments.
