300-445 Question 62
Select 3An organization has deployed a network assurance solution to monitor its enterprise network. As part of the implementation, they need to set a metric baseline for network performance. Which actions are most appropriate to set a reliable and effective metric baseline?
- A
Collect performance data during normal operational periods over a defined time frame.
- B
Use performance data from a single high-traffic event to establish the baseline.
- C
Incorporate data from similar network environments for comparative baseline creation.
- D
Identify and exclude outliers or anomalies in the collected performance data.
- E
Regularly update the baseline to reflect changes in network traffic patterns over time.
Show answer and explanation
Correct answers: A, D, E
Explanation
Setting a metric baseline involves collecting accurate and representative data of normal network operations. This ensures performance metrics are meaningful and deviations can be identified effectively. Excluding anomalies, focusing on typical operational data, and regularly updating the baseline are critical for maintaining relevant and actionable metrics.
- A. Correct.
Collecting performance data during normal operational periods is crucial to ensure the baseline reflects typical network activity rather than atypical conditions.
- B. Incorrect.
Using data from a single high-traffic event is not reliable for a baseline, as it represents an outlier rather than normal behavior.
- C. Incorrect.
While comparative data from similar environments might be useful for reference, baselines should be specific to the network being monitored.
- D. Correct.
Excluding outliers or anomalies ensures that the baseline represents standard performance and is not skewed by unusual events.
- E. Correct.
Regularly updating the baseline ensures it remains relevant and accounts for evolving network traffic patterns and usage trends.
