300-440 Question 291
Single answerYou are the network administrator for a large enterprise and have been tasked with troubleshooting connectivity issues experienced by several users in a branch office. Using Cisco DNA Center Assurance, you find that the Network Health score for the branch is low. Upon further investigation, you notice that the Device Health score of an access switch is also degraded. Which action should you take next to identify the root cause?
- A
Drill down into the 'Client Health' dashboard in Cisco DNA Center to check if specific users are experiencing issues.
- B
Review the 'Device 360' view for the affected switch to check for hardware, configuration, or software issues.
- C
Check the 'Application Experience' dashboard to identify if any applications are causing high traffic on the network.
- D
Run a Path Trace analysis in Cisco DNA Center to verify the end-to-end connectivity between the users and their destination.
Show answer and explanation
Correct answer: B
Explanation
When troubleshooting using Cisco DNA Center Assurance, focusing on the specific issue identified is critical. In this case, the degraded Device Health score points to potential issues with the access switch itself. The 'Device 360' view provides comprehensive details about the device's health, including hardware, software, and configuration, making it the most appropriate next step to identify the root cause.
- A. Incorrect.
While checking 'Client Health' can be useful, the problem identified in the scenario points to a degraded Device Health score, making this action less relevant at this stage.
- B. Correct.
The 'Device 360' view provides detailed insights into the health of the device, such as hardware, software, and configuration issues. This is the most appropriate next step to determine the root cause of the degraded Device Health score.
- C. Incorrect.
The 'Application Experience' dashboard focuses on application performance, which is not directly related to the degraded Device Health score in this scenario.
- D. Incorrect.
Running a Path Trace might be useful to verify end-to-end connectivity, but it does not directly address the degraded Device Health score highlighted in the scenario.
