A host in one org other organisation using another host with 25 m sec RTT. Network 1 Gbps link of this network tuned the administrator 1000 bytes to transfer large packet size to files optimally ovel utilisation >96%, how big to have chann (in terms of packets) should window size (assuming ACK packets have no be (assuming ACK pals impact)?
Answer: C. 3000 packets — Calculate the Bandwidth-Delay Product (BDP) by multiplying link speed and RTT: 1 Gbps × 25 ms = 25,000,000 bits. Convert packet size to bits: 1000 bytes × 8 =…

Show answer & explanation
Correct answer: C
Calculate the Bandwidth-Delay Product (BDP) by multiplying link speed and RTT: 1 Gbps × 25 ms = 25,000,000 bits. Convert packet size to bits: 1000 bytes × 8 = 8,000 bits. Determine maximum packets in flight: 25,000,000 / 8,000 = 3125 packets. Apply the utilization requirement: Window Size = 3125 × 0.96 = 3000 packets.
