300-440 Question 292
Select 3You are a network administrator, and a user reports intermittent connectivity issues when accessing a critical business application. Using Cisco DNA Center Assurance, you observe that the affected device has a poor health score and the network health score is also low. Which of the following actions would be the most effective steps to identify and resolve the issue?
- A
Check the 'Device 360' view in Cisco DNA Center for detailed information about the affected device, including interface errors and client connectivity.
- B
Analyze the 'Path Trace' tool in Cisco DNA Center to identify any potential bottlenecks or misconfigurations in the data path to the application.
- C
Reboot the user's device to refresh its network settings and clear any temporary connectivity issues.
- D
Examine the 'Network Health' dashboard in Cisco DNA Center to assess overall network performance and identify any trends or anomalies.
- E
Directly upgrade the firmware on the user's device to ensure it is running the latest version.
Show answer and explanation
Correct answers: A, B, D
Explanation
Cisco DNA Center Assurance provides advanced troubleshooting and diagnostic tools, such as the 'Device 360' view, 'Path Trace,' and 'Network Health' dashboard. These tools enable administrators to pinpoint the root cause of network and device issues effectively, rather than relying on less systematic methods like device reboots or immediate firmware upgrades. Using these features ensures a comprehensive and data-driven approach to resolving the connectivity issue.
- A. Correct.
The 'Device 360' view provides detailed insights into the health of the device, including its interfaces and connectivity metrics, making it a primary tool for troubleshooting.
- B. Correct.
The 'Path Trace' tool allows you to visualize the flow of traffic between the user's device and the application, helping to identify bottlenecks or misconfigurations.
- C. Incorrect.
Rebooting the device might temporarily resolve issues but does not address the root cause or leverage Cisco DNA Center's powerful diagnostic tools.
- D. Correct.
The 'Network Health' dashboard provides an overview of the network's overall performance and can reveal patterns or systemic issues affecting connectivity.
- E. Incorrect.
Upgrading firmware without identifying the root cause is premature and could introduce new issues, especially if the problem is unrelated to the firmware.
