300-445 Question 213
Single answerAn enterprise network operations center (NOC) uses a network assurance platform to monitor the health and performance of their network. Recently, they observed an alert for high latency on a specific application that was critical to business operations. Upon investigation, the platform provided detailed insights indicating increased packet loss and abnormal traffic patterns from a specific branch office. Which action should the NOC team prioritize to address the issue effectively?
- A
Analyze the network device logs at the branch office to identify any hardware or configuration issues.
- B
Increase the bandwidth allocation for the application on the affected branch office's network.
- C
Disable Quality of Service (QoS) policies on the network to allow unrestricted traffic flow.
- D
Reboot the affected application server to resolve potential performance bottlenecks.
Show answer and explanation
Correct answer: A
Explanation
The correct approach in this scenario is to analyze the network device logs to pinpoint the root cause of the high latency, packet loss, and abnormal traffic patterns. This step ensures that the issue is resolved at its source rather than applying temporary or unrelated fixes like bandwidth adjustments or server reboots.
- A. Correct.
Analyzing network device logs at the branch office will help identify the root cause of the packet loss and abnormal traffic patterns. This is a critical troubleshooting step to address the issue effectively.
- B. Incorrect.
Increasing bandwidth allocation without understanding the root cause is not the correct approach, as the issue may not be related to insufficient bandwidth.
- C. Incorrect.
Disabling QoS policies can lead to further performance degradation by removing prioritization for critical traffic, which is not recommended.
- D. Incorrect.
Rebooting the application server may not address the underlying network-related issue and could result in unnecessary downtime.
