Which of the following TCP flags are used for establishing a network connection via a TCP three-way handshake? (Select 2 answers)

Transmission Control Protocol (TCP) is an example of a connectionless protocol. Because TCP does not support a three-way handshake while establishing a network connection, it is referred to as an unreliable or best-effort protocol. Example applications of TCP include transmission of video and audio streaming data.

User Datagram Protocol (UDP) is a connection-oriented protocol using a three-way handshake, a set of initial steps required for establishing a network connection. UDP supports retransmission of lost packets, flow control (managing the amount of data being sent), and sequencing (rearranging packets that arrived out of order). Example applications of UDP include the transmission of text and image data.
