- 3001
- 4000
- 1000
Explanation: The file server will send back an acknowledgement number of 3001 to host A after receiving the first three segments. The starting sequence number was 1. 1000 bytes were sent in each of the three segments for a total of 3000 bytes. Because the initial sequence number was 1, the last byte sent was byte number 3000. The file server will now expect to receive byte number 3001 and above. Therefore, it communicates to host A through the acknowledgement number of 3001.
