300-445 Question 173
Single answerYour organization is experiencing intermittent network performance issues. You are tasked with analyzing historical data from your enterprise network assurance platform to determine the root cause. Which data analysis approach would be the most effective to identify patterns in traffic flow anomalies over time?
- A
Time-series analysis of network traffic metrics such as bandwidth utilization and latency.
- B
Real-time packet capture and inspection for all network traffic.
- C
Correlation of network device logs with external threat intelligence feeds.
- D
Manual inspection of configuration files on network devices.
Show answer and explanation
Correct answer: A
Explanation
Time-series analysis allows you to evaluate historical data trends and identify patterns in network behavior, making it the most effective method for diagnosing intermittent network performance issues. Other approaches, while useful in specific contexts, do not provide the comprehensive insights required for this scenario.
- A. Correct.
Time-series analysis is the best approach to identify trends, recurring anomalies, or patterns in network traffic over a historical period, which is critical for diagnosing intermittent issues.
- B. Incorrect.
Real-time packet capture is useful for immediate troubleshooting but is not suitable for analyzing long-term or historical trends to identify patterns.
- C. Incorrect.
Correlation of device logs with threat intelligence helps in identifying potential security threats but is not directly effective for analyzing traffic flow anomalies.
- D. Incorrect.
Manual inspection of configuration files may help in identifying misconfigurations but does not address the analysis of traffic flow anomalies over time.
