300-445 Question 216
Single answerAn enterprise network operations team is using an assurance platform to monitor network health and performance. They notice repeated high-latency alerts for a specific WAN link. To investigate, they examine the provided insights and alerts. Which step should they take as the next best action based on the provided insights?
- A
Analyze the traffic patterns on the WAN link to identify potential congestion or bandwidth issues.
- B
Disable the alert for high latency on the WAN link to prevent further notifications.
- C
Upgrade the WAN link to a higher bandwidth without further investigation.
- D
Reboot all devices connected to the WAN link to resolve the latency issue.
Show answer and explanation
Correct answer: A
Explanation
The correct action when dealing with high-latency alerts is to first gather more information by analyzing the traffic patterns on the affected link. This step helps identify potential causes such as congestion, application misbehavior, or policy misconfigurations. Taking other actions, such as disabling alerts or upgrading bandwidth, without analysis risks missing the actual root cause.
- A. Correct.
Analyzing traffic patterns is the correct next step because it provides more context to identify the root cause of the high-latency alerts, such as congestion or misconfigured traffic policies.
- B. Incorrect.
Disabling the alert without addressing the underlying issue is not a recommended action for network assurance as it leaves the problem unresolved and risks further degradation.
- C. Incorrect.
Upgrading the WAN link without investigating the cause of latency is premature and could lead to unnecessary costs without solving the problem if the issue lies elsewhere.
- D. Incorrect.
Rebooting devices should only be considered as a last resort and is not typically the first action when troubleshooting high-latency alerts.
