A network administrator is analyzing a TCP connection that is transferring data. The capture shows that the sender's congestion window is decreasing after a packet loss event. What is the purpose of this behavior?

To reduce the amount of data sent to alleviate network congestion

To increase the retransmission timeout

To ensure packets are delivered in order

To reduce the receiver's buffer usage

A network administrator is troubleshooting a slow file transfer between two servers. The administrator notices that TCP is retransmitting segments frequently. What is the most likely cause of the retransmissions?

The receiving server is not sending acknowledgments for received segments.

The sending server is using a small window size, which limits throughput.

The application is using UDP, which does not guarantee delivery.

The network is experiencing high latency, but no packets are being lost.

A network administrator is troubleshooting a TCP connection that is transferring data very slowly. The capture shows that the sender's window is consistently small, and the receiver is advertising a large window. What is the most likely cause of the slow transfer?

The application is using UDP instead of TCP

The three-way handshake was not completed

Network congestion is causing the sender to reduce its congestion window

A server is sending a large file to a client over TCP. The client's receive window is advertised as 0 in an acknowledgment. What should the server do?

Reduce the segment size and continue

Continue sending at the same rate

Stop sending until the client advertises a nonzero window

Retransmit the last segment immediately

A network engineer is designing a system for streaming stock market prices to traders. The prices change rapidly, and traders need the latest price as soon as possible. If a price update is lost, the next update will supersede it. However, the system also sends trade orders that must be executed exactly once. The engineer uses UDP for price feeds and TCP for trade orders. What is the main reason for this design?

UDP provides lower latency for price updates, while TCP ensures trade orders are not lost

UDP guarantees that trade orders are executed in order

TCP cannot handle high-frequency data
