300-445 Question 57
Select 3An enterprise network team is tasked with setting a performance metric baseline for their newly implemented SD-WAN environment. Which actions should the team take to ensure the baseline is meaningful and effective for ongoing network assurance?
- A
Collect performance data during normal business hours over a representative time period.
- B
Use data from a single high-traffic day to define the baseline.
- C
Exclude outliers, such as unusual spikes, when calculating the baseline metrics.
- D
Establish baselines for key performance indicators (KPIs) including latency, jitter, and bandwidth utilization.
- E
Rely on historical baselines from a legacy WAN setup without adjustments.
Show answer and explanation
Correct answers: A, C, D
Explanation
Setting an effective metric baseline requires using representative data collected during normal operating conditions, excluding outliers to avoid skewed results, and defining baselines for relevant KPIs. These practices ensure the baseline is both accurate and applicable for monitoring and troubleshooting in the enterprise network environment. Avoiding shortcuts, such as relying on legacy data or atypical days, is essential for meaningful network assurance.
- A. Correct.
Collecting data during normal business hours over a representative time period ensures the baseline reflects typical network performance and usage patterns.
- B. Incorrect.
Using data from a single high-traffic day does not provide a representative view of typical network behavior, leading to an inaccurate baseline.
- C. Correct.
Excluding unusual spikes or outliers helps avoid skewed baselines that do not reflect normal network conditions.
- D. Correct.
Focusing on key performance indicators (KPIs) relevant to the SD-WAN environment ensures that the baseline is actionable and aligned with performance and assurance goals.
- E. Incorrect.
Relying on historical baselines from a legacy WAN may not account for the differences in architecture, traffic patterns, or performance expectations in the SD-WAN environment, leading to inaccurate conclusions.
