300-445 Question 210
Select 3Your organization has implemented a network assurance solution to monitor and ensure the health of its enterprise network. The system has begun generating numerous alerts about high latency between two critical data centers. As the network engineer, you want to verify the insights provided by the system and address the issue. Which actions should you take to ensure the alerts are valid and actionable?
- A
Verify the alert details by analyzing historical performance data for the affected links.
- B
Immediately disable all alerts for high latency to avoid alert fatigue.
- C
Correlate the high latency alerts with other network events such as link failures or configuration changes.
- D
Engage with the application teams to confirm if the latency is impacting business-critical applications.
- E
Manually increase the threshold for high latency alerts to reduce the number of alerts.
Show answer and explanation
Correct answers: A, C, D
Explanation
To address network assurance alerts effectively, it is critical to validate the alerts using historical data, correlate them with related events, and involve application teams to assess business impact. These steps ensure that alerts are actionable, relevant, and prioritized appropriately, without suppressing potentially important notifications.
- A. Correct.
Analyzing historical performance data allows you to determine if this high latency is part of a recurring issue, a sudden anomaly, or a trend. This is a necessary step in validating the alert.
- B. Incorrect.
Disabling alerts without understanding their cause is not a best practice. It could lead to missing critical issues, and doing so does not address the underlying problem.
- C. Correct.
Correlating the alerts with other network events helps identify potential root causes, such as recent configuration changes or link failures, providing actionable insights.
- D. Correct.
Engaging application teams ensures that the high latency is investigated in the context of its impact on business-critical applications, helping prioritize remediation efforts.
- E. Incorrect.
Increasing the threshold without proper analysis can suppress valid alerts, potentially causing critical issues to go unnoticed.
