Exam Professional Cloud Network Engineer topic 1 question 31 discussion

Correct Answer is (A) As the question states that the RTT is 100ms thus low transfer rate is due to the TCP window size that is too small. And the solution is to increase the window size .

The correct option is A. The issue of underutilizing the available 10-Gbps bandwidth is often related to TCP configuration. By tuning TCP parameters, such as TCP window size and congestion control algorithms, you can optimize the connection for high-bandwidth, high-latency environments like your 100-ms round-trip time (RTT) peering connection. This adjustment allows gsutil to take better advantage of the available bandwidth.

Even if you are not aware of all the options, question is asked about what to do on the on prem servers. All other option includes cloud except A

A: The TCP window is the maximum number of bytes that can be sent before the ACK must be received. If either the sender or receiver are frequently forced to stop and wait for ACKs for previously sent packets, gaps in the data flow are created, which limits the maximum throughput of the connection.

Correct Answer is A

I would roll with D, since gsutil kindly provides a tool to analyze performance issues.

A Like most modern operating systems, Linux now does a good job of auto-tuning the TCP buffers. In some cases, the default maximum Linux TCP buffer sizes are still too small. When this is the case, you can observe an effect called the Bandwidth Delay Product. The TCP window is the maximum number of bytes that can be sent before the ACK must be received. If either the sender or receiver are frequently forced to stop and wait for ACKs for previously sent packets, gaps in the data flow are created, which limits the maximum throughput of the connection.

Answer is : A

A is correct

Correct Answer is (A) its the only logical solution as its truly the limiting factor here.

Ans - A
