300-445 Question 171
Single answerYour enterprise network has been experiencing intermittent slowdowns during peak business hours. You have implemented a network assurance solution that collects telemetry data from all devices. Which data analysis technique would be most appropriate to identify the root cause of the performance issues?
- A
Trend analysis to detect long-term usage patterns
- B
Anomaly detection to identify deviations from normal behavior
- C
Correlation analysis to compare network metrics with application performance
- D
Descriptive statistics to summarize network data
Show answer and explanation
Correct answer: B
Explanation
Anomaly detection is the most effective technique in this scenario because it focuses on identifying deviations from the normal network behavior, which is critical when diagnosing intermittent performance issues. By pinpointing anomalies during the peak hours, network administrators can isolate and address the root cause of the slowdowns.
- A. Incorrect.
Trend analysis is useful for understanding long-term patterns over time but does not provide actionable insights for identifying the specific root cause of intermittent issues.
- B. Correct.
Anomaly detection is the most appropriate technique in this scenario as it helps identify unusual deviations in network behavior during the specific time frames when the slowdowns occur.
- C. Incorrect.
Correlation analysis is valuable for understanding relationships between variables, but it requires prior knowledge of which metrics to compare. It is less suited for identifying the root cause in this scenario.
- D. Incorrect.
Descriptive statistics summarize data but do not provide insights into unusual behavior or the root cause of performance issues.
