300-445 Question 176
Single answerAn enterprise network operations team is analyzing data collected from multiple network devices using a network assurance tool. They notice a sudden increase in latency across multiple sites. Which data analysis technique should the team use to identify the root cause of the latency issue?
- A
Correlation analysis to identify patterns between latency and other metrics like bandwidth utilization.
- B
Regression analysis to predict future latency trends based on historical data.
- C
Descriptive analysis to summarize the average latency across all sites.
- D
Clustering analysis to group devices based on similar latency metrics.
Show answer and explanation
Correct answer: A
Explanation
To identify the root cause of a sudden increase in latency, the team should focus on analyzing relationships between metrics. Correlation analysis is the most appropriate technique as it allows the team to determine whether there is a relationship between latency and other network metrics, such as bandwidth utilization or error rates, which could be contributing to the issue.
- A. Correct.
Correlation analysis is the correct technique to identify relationships between latency and other network metrics, such as bandwidth utilization or packet loss, which can help determine the root cause of the issue.
- B. Incorrect.
Regression analysis is primarily used for forecasting or predicting future trends and is not suitable for identifying the root cause of current latency issues.
- C. Incorrect.
Descriptive analysis provides summaries or averages but does not help in identifying specific patterns or relationships that could indicate the root cause.
- D. Incorrect.
Clustering analysis is used to group similar data points, such as devices with similar behavior, but it is not the best method to determine relationships or root causes of a specific issue like increased latency.
