300-445 Question 140
Select 3An enterprise network is experiencing frequent slowdowns on its web-based applications, which are critical for employee productivity. As part of the network assurance process, you are tasked with designing monitoring and diagnostic solutions for web traffic. Which of the following actions should you take to ensure consistent performance and identify the root cause effectively?
- A
Implement application-aware traffic monitoring to analyze specific web application performance metrics.
- B
Enable NetFlow or IPFIX to gather detailed traffic flows and identify bottlenecks.
- C
Disable HTTPS to simplify traffic analysis by avoiding encryption complexities.
- D
Deploy synthetic transaction monitoring to simulate user interactions with web applications.
- E
Rely solely on SNMP-based monitoring for web traffic performance.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure consistent performance and diagnose issues with web traffic in an enterprise network, it is essential to combine application-aware monitoring, traffic flow analysis (e.g., via NetFlow/IPFIX), and proactive tools like synthetic transaction monitoring. These methods collectively help identify bottlenecks, monitor application performance, and proactively detect potential issues. Disabling HTTPS is a poor practice that compromises security, and relying solely on SNMP is insufficient for detailed application-level insights.
- A. Correct.
Implementing application-aware traffic monitoring allows you to analyze how specific web applications are performing, providing deeper insights into potential performance issues.
- B. Correct.
NetFlow or IPFIX enables the collection of detailed traffic flow data, which can help identify bottlenecks or anomalies in network traffic affecting web applications.
- C. Incorrect.
Disabling HTTPS is not a recommended practice as it compromises security and violates modern compliance standards. Traffic analysis should be performed using methods that respect encryption.
- D. Correct.
Synthetic transaction monitoring simulates user interactions with web applications, providing proactive insights into performance and availability issues before real users are impacted.
- E. Incorrect.
SNMP-based monitoring lacks the granularity required for deep web traffic analysis and cannot provide detailed insights into application performance.
