CCNP Network Assurance Practice Question
A network administrator is using Cisco DNA Center Assurance to monitor the health of wireless clients. The administrator notices that some clients are experiencing poor performance, but the Assurance dashboard shows them as 'Good'. Which action should the administrator take to troubleshoot the issue?
⚠ Common exam trap
The trap here is assuming that the overall client health score in Assurance is sufficient to diagnose all performance issues, when in fact detailed metrics are needed.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the client's detailed health metrics, including RSSI, SNR, and retry rates.
Cisco DNA Center Assurance client health scores are composite metrics that may not reflect all RF issues. When clients report poor performance but show 'Good' health, the administrator should examine detailed client metrics such as RSSI, SNR, and retry rates to uncover hidden problems. The other options are either too broad or unnecessary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Verify that the wireless controller is registered with Cisco DNA Center.
Why it's wrong here
If the wireless controller was not registered, Assurance would not have data for the clients at all. Since the clients are visible and show a health status, the controller is already integrated. Checking registration does not help diagnose the poor performance of specific clients and is therefore not the right action.
- ✗
Check the overall network health dashboard for any global alerts.
Why it's wrong here
The overall network health dashboard shows aggregate health and alerts, but it may not highlight issues affecting individual clients. Since the problem is with specific clients, looking at the global dashboard is unlikely to reveal the detailed RF metrics needed. It is a less effective troubleshooting step compared to examining client-specific data.
- ✗
Restart the Cisco DNA Center Assurance service.
Why it's wrong here
Restarting the Assurance service is a drastic action that would disrupt monitoring for all devices and clients. It does not address the underlying issue of poor client performance and is not a recommended troubleshooting step. The problem is likely due to RF conditions or client-specific factors, not a service malfunction.
- ✓
Review the client's detailed health metrics, including RSSI, SNR, and retry rates.
Why this is correct
Cisco DNA Center Assurance provides detailed client health metrics beyond the overall health score. By drilling down into a specific client's details, you can view RSSI, SNR, retry rates, and other RF parameters that may indicate poor performance despite an overall 'Good' status. This granular data helps identify the root cause of the issue.
