Question 17Asked in DSSSB TGT Computer Science (Technical), 12 Sep 2025, Shift 3 (5:00 PM)

How does TCP ensure a clean termination of both sides during a normal connection release?

  1. ABy resending SYN packets
  2. BBy encrypting all termination packets
  3. CBy entering the LISTEN state after termination
  4. DBy sending FIN and ACK packets sequentially
Show answerHide answer

Correct answer: (D) By sending FIN and ACK packets sequentially

Explanation

In a normal TCP release, each side sends a FIN and the other side acknowledges it with an ACK (usually four segments). This closes both directions of the connection cleanly.
