300-445 Question 63
Select 3An enterprise network team is tasked with setting a performance metric baseline for their newly deployed network monitoring system. The team wants to ensure accurate baselines that reflect typical network behavior under normal conditions. Which actions should the team take to establish an effective baseline?
- A
Collect metric data during peak and off-peak hours over a consistent time period.
- B
Use the baseline metrics from a similar network in another organization to save time.
- C
Exclude outlier data points that result from one-time events like maintenance windows.
- D
Analyze historical data and trends to identify typical network behavior.
- E
Set baselines based on the highest observed metric values to anticipate worst-case scenarios.
Show answer and explanation
Correct answers: A, C, D
Explanation
Setting an effective metric baseline involves collecting representative data over time, excluding anomalies, and leveraging historical trends for accuracy. This ensures that the baseline reflects typical network behavior, allowing network assurance tools to detect and respond to deviations effectively while avoiding false positives or negatives.
- A. Correct.
Collecting metric data during both peak and off-peak hours ensures the baseline captures variations in network behavior over different conditions, making it more representative.
- B. Incorrect.
Using baseline metrics from another organization is not recommended, as every network has unique characteristics and usage patterns.
- C. Correct.
Excluding outlier data points avoids skewing the baseline with values that do not represent typical network behavior, ensuring accuracy.
- D. Correct.
Analyzing historical data and trends provides valuable context for understanding what 'normal' looks like for the specific network, which is critical for setting accurate baselines.
- E. Incorrect.
Setting baselines based on the highest observed values would not reflect normal behavior and could result in misleading thresholds for network performance.
