300-445 Question 64
Select 3An enterprise network administrator is tasked with setting a metric baseline for network performance monitoring. The goal is to establish a reference point for evaluating anomalies in the network. Which of the following actions are essential when setting metric baselines?
- A
Collect data over a representative time period that includes both peak and normal usage patterns.
- B
Set fixed thresholds based only on vendor recommendations for all metrics.
- C
Continuously monitor and adjust the baseline as network usage evolves over time.
- D
Exclude any outliers from the collected data to ensure the baseline only reflects consistent behavior.
- E
Use historical data to define what constitutes normal network behavior.
Show answer and explanation
Correct answers: A, C, E
Explanation
To set an effective metric baseline, it’s essential to gather representative data, include historical trends, and ensure continuous adjustment as the network evolves. This approach ensures the baseline accurately reflects normal network behavior and can be used to detect significant anomalies effectively. Fixed thresholds or exclusion of outliers can lead to inaccurate baselines and missed opportunities to identify critical network events.
- A. Correct.
Collecting data over a representative time period ensures the baseline reflects both typical and peak usage patterns, making it more accurate for anomaly detection.
- B. Incorrect.
Fixed thresholds based solely on vendor recommendations may not account for the unique characteristics of the enterprise network.
- C. Correct.
Baselines should be dynamic and periodically reviewed to adapt to changes in network behavior, ensuring continued accuracy.
- D. Incorrect.
Outliers should not be excluded entirely, as they may highlight critical trends or anomalies that need to be accounted for in the baseline.
- E. Correct.
Historical data provides valuable insight into normal network behavior, which is essential for defining an accurate baseline.
