200-901 Question 202
Select 3A development team has deployed a cloud-based application that streams live video to users. Some users report buffering and poor video quality during peak usage hours. Upon investigation, the network team identifies high latency and limited bandwidth between the application servers and the end users. Which network constraints are most likely impacting the application performance?
- A
High latency between servers and end users
- B
Insufficient bandwidth available for the application
- C
Reliable and consistent network connections
- D
Packet loss during data transmission
- E
High server CPU utilization
Show answer and explanation
Correct answers: A, B, D
Explanation
The application's performance issues are directly tied to network constraints such as high latency, insufficient bandwidth, and packet loss. These factors directly affect the delivery of video streams in real-time, leading to buffering and poor user experience. Understanding and mitigating these constraints is critical for optimizing application performance.
- A. Correct.
High latency can delay the delivery of video data, causing buffering and reduced performance, especially in real-time applications like video streaming.
- B. Correct.
Insufficient bandwidth can prevent the application from delivering video streams smoothly, resulting in reduced quality or buffering.
- C. Incorrect.
Reliable and consistent network connections generally improve performance and are not a constraint; this option does not apply to the reported problem.
- D. Correct.
Packet loss can disrupt the video stream, causing delays, buffering, or even corrupted playback.
- E. Incorrect.
High server CPU utilization is related to processing power, not network constraints, so it is not relevant to the issue described.
