300-410 Question 288
Single answerA network administrator is using Cisco DNA Center Assurance to troubleshoot a connectivity issue reported by users in a branch office. The users are unable to reach an external web application. The administrator notices that the device health for the branch router is marked as 'Critical' in Cisco DNA Center Assurance. Which action should the administrator take next to identify the root cause of the issue?
- A
Check the interface status and errors on the branch router using Cisco DNA Center.
- B
Analyze the Client 360 view in Cisco DNA Center to inspect connected clients.
- C
Review the Application Health dashboard to identify any application-level issues.
- D
Use the Path Trace tool in Cisco DNA Center to trace the traffic path to the web application.
Show answer and explanation
Correct answer: A
Explanation
The branch router's 'Critical' health status in Cisco DNA Center Assurance suggests a device-level issue. The administrator should first examine the branch router's interfaces for errors or misconfigurations, as these are common causes of connectivity problems. While other tools like Client 360 and Path Trace are useful in different scenarios, they are not the most relevant for addressing the immediate issue of the router's health.
- A. Correct.
Correct. Checking the interface status and errors on the branch router is a logical first step because the router's 'Critical' health status indicates a device-level problem. Cisco DNA Center provides interface-level details that can help identify issues like high error rates, interface down states, or bandwidth congestion.
- B. Incorrect.
Incorrect. The Client 360 view is used to analyze specific client connectivity issues. In this case, the issue seems to be related to the branch router's health, not individual clients.
- C. Incorrect.
Incorrect. The Application Health dashboard focuses on application-level performance metrics. However, the problem appears to be related to the branch router's health rather than the application itself.
- D. Incorrect.
Incorrect. The Path Trace tool is useful for analyzing end-to-end traffic paths. However, since the branch router's health is 'Critical,' the issue is likely at the device level, making Path Trace unnecessary at this stage.
