300-445 Question 139
Select 4Your organization has implemented a network assurance solution to monitor and analyze the performance of web-based applications hosted on a private cloud. The solution integrates with web servers and uses telemetry data to detect anomalies in HTTP response times. Recently, users reported intermittent slowness while accessing the web applications. Which of the following features should you prioritize to diagnose the issue effectively?
- A
HTTP response code analysis to identify server or application errors
- B
Network flow analysis to isolate potential bandwidth bottlenecks
- C
TLS certificate expiry monitoring to ensure secure connections
- D
Correlation of user activity logs with HTTP response times to detect patterns
- E
DNS resolution time tracking to identify latency in name resolution
Show answer and explanation
Correct answers: A, B, D, E
Explanation
To diagnose intermittent slowness in web applications, it is essential to analyze both server-side and network-related aspects. HTTP response code analysis can reveal application-level errors, while network flow analysis isolates bandwidth-related issues. Correlating user activity and HTTP response patterns provides deeper visibility into potential root causes, and DNS resolution tracking helps identify latency in the name resolution process. TLS certificate expiry monitoring, while important for security, does not contribute directly to performance diagnostics in this scenario.
- A. Correct.
HTTP response code analysis is critical to identify potential server-side or application-level errors affecting performance.
- B. Correct.
Network flow analysis helps isolate network-related issues, such as bandwidth bottlenecks, that could be contributing to the slowness.
- C. Incorrect.
TLS certificate expiry monitoring is important for security but does not directly address performance issues like slowness.
- D. Correct.
Correlating user activity logs with HTTP response times allows you to identify patterns and determine if specific activities or user behaviors are causing the slowness.
- E. Correct.
DNS resolution time tracking is essential to detect delays caused by name resolution, which can impact the overall performance of web-based applications.
