300-445 Question 138
Select 3An enterprise has deployed a new web-based network assurance dashboard hosted on their private cloud. The application provides insights into network health and performance. Users report slow and inconsistent loading times when accessing the dashboard. As the network assurance architect, which steps should you take to troubleshoot and resolve the issue?
- A
Verify the web server's CPU, memory, and disk usage to identify potential resource constraints.
- B
Analyze the application's front-end code for inefficiencies in rendering or data requests.
- C
Inspect network latency and packet loss between users and the web server.
- D
Increase the bandwidth allocation on the web server without conducting further analysis.
- E
Review the web server's SSL/TLS configuration to ensure secure communication.
Show answer and explanation
Correct answers: A, B, C
Explanation
To troubleshoot web performance issues effectively, it is essential to consider all potential factors, including server resource constraints, application inefficiencies, and network performance. Analyzing these areas will help identify and resolve the root cause of the slow and inconsistent loading times reported by users.
- A. Correct.
Examining the web server's resource usage can reveal performance bottlenecks, such as insufficient CPU or memory, that may cause slow loading times.
- B. Correct.
Analyzing the front-end code is critical, as inefficient scripts or excessive data requests can significantly impact loading performance.
- C. Correct.
High latency or packet loss in the network path can result in slow or inconsistent loading of web-based applications, making it crucial to verify network performance.
- D. Incorrect.
Increasing bandwidth without analysis is not a targeted solution and may not address the root cause of the issue.
- E. Incorrect.
While reviewing SSL/TLS configurations is important for security, it is not directly tied to performance issues like slow loading times unless misconfigurations are causing delays.
