300-445 Question 142
Select 3An organization is deploying a network assurance solution to monitor the health and performance of its web applications hosted on a hybrid cloud. The IT team wants to ensure real-time visibility into HTTP request/response performance and identify issues such as latency, dropped connections, and application failures. Which of the following capabilities should the network assurance solution include?
- A
Deep Packet Inspection (DPI) to analyze HTTP/HTTPS traffic
- B
Synthetic transaction monitoring to simulate user interactions
- C
Integration with SIEM tools for security event correlation
- D
Real-time alerts based on predefined HTTP performance thresholds
- E
Support for DNS resolution monitoring
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure network assurance for web applications, the solution must include capabilities to monitor and analyze HTTP/HTTPS traffic, proactively simulate interactions, and provide real-time alerts for performance deviations. These features ensure the IT team can maintain the health and performance of web applications hosted in a hybrid cloud environment.
- A. Correct.
Deep Packet Inspection (DPI) is essential to analyze the details of HTTP/HTTPS traffic and provide insights into performance and potential issues such as latency or dropped connections.
- B. Correct.
Synthetic transaction monitoring helps simulate user interactions with the web application, enabling the IT team to proactively identify performance or application-level issues.
- C. Incorrect.
While integration with SIEM tools is valuable for security monitoring, it is not directly related to web application performance or network assurance specific to HTTP traffic.
- D. Correct.
Real-time alerts based on predefined HTTP performance thresholds allow the IT team to respond quickly to issues such as increased latency or failed HTTP requests, ensuring web application health.
- E. Incorrect.
DNS resolution monitoring is useful for tracking domain name resolution issues but is not directly focused on HTTP performance or application-level assurance.
