350-401 Network Assurance Practice Question
A network administrator is troubleshooting a network issue using Cisco DNA Center Assurance. The administrator wants to identify which network devices are experiencing the highest number of errors, such as CRC errors and interface flaps. Which Assurance dashboard should the administrator use?
⚠ Common exam trap
The trap here is assuming that Client Health or Application Health would show device-level error statistics, when they focus on clients and applications respectively.
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
✓
Network Health
The Network Health dashboard in Cisco DNA Center Assurance aggregates health metrics for network devices and links, including error counters like CRC errors and interface flaps. It ranks devices by health and highlights those with the most issues, enabling administrators to quickly pinpoint and address problems. This makes it the right choice for identifying devices with high error rates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Client Health
Why it's wrong here
Client Health focuses on the experience of client devices, such as onboarding and connectivity. It does not provide detailed error counters for network devices like CRC errors. While client issues may be caused by device errors, the dashboard itself does not show device-level error statistics. Network Health is the correct place for device errors.
- ✓
Network Health
Why this is correct
The Network Health dashboard in Cisco DNA Center Assurance provides an overview of device and link health, including error counters such as CRC errors and interface flaps. It highlights devices with the most issues, allowing administrators to quickly identify problematic areas. This is the appropriate dashboard for finding devices with high error rates.
- ✗
Application Health
Why it's wrong here
Application Health is centered on application performance and usage, not on network device errors. It can show which applications are experiencing issues, but it does not list devices with CRC errors or flaps. For device-level error analysis, the Network Health dashboard is required.
- ✗
Path Trace
Why it's wrong here
Path Trace is used to simulate and analyze the path between two endpoints, showing the forwarding path and any ACL or QoS configurations. It does not provide a summary of devices with the highest error counts. While it can be used to troubleshoot specific paths, it is not the dashboard for identifying devices with many errors.
