350-401 Network Assurance Practice Question
A network engineer is using Cisco DNA Center Assurance to troubleshoot a client connectivity issue. The engineer notices that the client's health score is low due to onboarding failures. Which component of Cisco DNA Center Assurance should be examined first to identify the root cause?
⚠ Common exam trap
Many exam-takers confuse network-wide health monitoring with client-specific troubleshooting, leading to choosing Network Health instead of Client 360.
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
✓
Client 360
Client 360 is the correct component because it provides detailed information about a specific client's onboarding process, including authentication, DHCP, and DNS steps. It allows the engineer to pinpoint the exact failure point. Network Health, Application Health, and Path Trace offer broader or different perspectives that do not focus on individual client onboarding.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Network Health
Why it's wrong here
Network Health provides an overall view of the network's health, including wired and wireless devices, but it does not drill down into individual client onboarding issues. It might show a dip in health score due to client failures, but it does not provide the granular details needed to troubleshoot a specific client's onboarding problem. Therefore, it is not the first place to look.
- ✗
Application Health
Why it's wrong here
Application Health focuses on the performance of applications and their network dependencies. It is useful for troubleshooting application performance issues, not client onboarding failures. Onboarding involves Layer 2 and Layer 3 connectivity, authentication, and IP address assignment, which are not covered in Application Health. Thus, it is not relevant for this scenario.
- ✗
Path Trace
Why it's wrong here
Path Trace is used to visualize the path of a flow between two endpoints, including details of each hop. While it can help identify where traffic is dropped, it is not specifically designed for troubleshooting client onboarding. Onboarding failures occur before the client can send traffic, so Path Trace would not capture the onboarding process. Therefore, it is not the correct tool.
- ✓
Client 360
Why this is correct
Client 360 provides a comprehensive view of a specific client's connectivity, including onboarding, authentication, and performance details. It shows the client's journey through the network, including association, authentication, DHCP, and DNS. For onboarding failures, Client 360 will display the exact step where the failure occurred, such as authentication failure or DHCP timeout, making it the primary tool for root cause analysis.
