300-445 Question 120
Select 3A financial services company is experiencing poor performance with their real-time trading application. Upon investigation, the network team identifies that the application uses UDP for data transmission. What network characteristics should the team focus on to diagnose and resolve the issue?
- A
Packet loss
- B
Jitter
- C
Latency
- D
TCP window size
- E
Throughput
Show answer and explanation
Correct answers: A, B, C
Explanation
Real-time applications like trading platforms rely on UDP for fast data transmission but are highly sensitive to packet loss, jitter, and latency. These factors directly affect the performance and reliability of the application. Focusing on these network characteristics will help the team identify and resolve the root cause of the performance issues.
- A. Correct.
Packet loss is a critical factor for UDP-based applications as it can result in missing data, especially for real-time applications like trading systems.
- B. Correct.
Jitter, which refers to variations in packet delay, can disrupt the performance of real-time applications, making it an essential metric to monitor.
- C. Correct.
Latency measures the delay in transmission, which directly impacts time-sensitive applications like trading, where every millisecond counts.
- D. Incorrect.
TCP window size is irrelevant in this context because the application uses UDP, which does not utilize flow control mechanisms like TCP.
- E. Incorrect.
While throughput is important for overall network performance, it is not a primary concern in this scenario, as the focus is on minimizing delays and disruptions for real-time traffic.
