300-415 Question 301
Single answerYour organization is using Cisco vManage to monitor and manage its SD-WAN environment. The IT team has recently reported issues with delayed alert notifications from vManage and outdated performance metrics being displayed on the dashboard. Which of the following actions would most effectively address this issue?
- A
Verify the NTP configuration on all SD-WAN devices and the vManage system.
- B
Increase the CPU and memory resources allocated to the vManage server.
- C
Reboot all SD-WAN devices to refresh their connection to vManage.
- D
Enable SNMP polling on vManage for faster metric collection.
Show answer and explanation
Correct answer: A
Explanation
Time synchronization is critical in a Cisco SD-WAN environment. If the vManage server or SD-WAN devices are not synchronized correctly, it can result in delayed alerts and outdated metrics. Verifying and correcting the NTP configuration ensures consistent and accurate time across the system, which is essential for real-time monitoring and alerting.
- A. Correct.
Ensuring the NTP configuration is accurate across all SD-WAN devices and the vManage system prevents time synchronization issues, which can lead to delayed alerts and outdated data.
- B. Incorrect.
While increasing CPU and memory resources might improve vManage performance under heavy load, it does not address the root cause of delayed alerts and outdated metrics, which is likely a time synchronization issue.
- C. Incorrect.
Rebooting all SD-WAN devices would cause unnecessary downtime and does not directly address the issue of delayed alerts or outdated metrics.
- D. Incorrect.
SNMP polling is used for specific device monitoring but is not the primary method for resolving delayed alerts or outdated data in the context of SD-WAN management.
