A client is establishing a TCP session with a server. How is the acknowledgment number in the response segment to the client determined?

• The acknowledgment number is set to 11 to signify an acknowledgment packet and synchronization packet back to the client.
• The acknowledgment number field uses a random source port number in response to the client.
• The acknowledgment number field is modified by adding 1 to the randomly chosen initial sequence number in response to the client.
• The acknowledgment number is set to 1 to signify an acknowledgment packet back to the client.

Explanation: To establish a session with the client, the TCP server will acknowledge the receipt of the SYN segment from the client. The server sends a segment back to the client with the ACK flag set indicating that the acknowledgment number is significant.The value of the acknowledgment number field is equal to the randomly chosen initial sequence number (ISN) plus 1.
