CCNP Network Assurance Practice Question
A network administrator is using Cisco DNA Center Assurance to troubleshoot a user's poor voice quality. The administrator wants to identify whether the issue is related to the network or the application. Which two Assurance features should be used to gather relevant data? (Choose two.)
⚠ Common exam trap
The trap here is assuming that the Network Health Dashboard provides application-level details, but it only shows device health, not voice quality metrics.
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
✓
Application Health
To troubleshoot poor voice quality, the administrator should use Application Health to get application-specific performance metrics such as jitter and packet loss, and Client 360 to examine the specific client's connectivity and RF conditions. Together, these features provide a comprehensive view of both the application and the client's network experience. Other features like the Network Health Dashboard or Sensor Test offer broader or synthetic data, which may not pinpoint the issue for a specific user. Thus, Application Health and Client 360 are the correct choices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Application Health
Why this is correct
Application Health provides detailed metrics on application performance, including network latency, jitter, and packet loss for specific applications like voice. It can help determine if the voice quality issue is due to the application itself or the network path. By analyzing application-specific data, the administrator can isolate whether the problem is within the application or the underlying network.
- ✗
Network Health Dashboard
Why it's wrong here
The Network Health Dashboard gives an overall view of network device health, such as switch and router CPU, interface errors, and wireless AP status. While it can indicate network-wide issues, it does not provide application-specific performance metrics. It is useful for identifying network outages or degradation, but for voice quality, a more granular application-focused tool is needed.
- ✓
Client 360
Why this is correct
Client 360 provides a detailed view of the specific client's connectivity, including wireless signal strength, roaming history, and QoS markings. For voice quality issues, it can show if the client experienced poor RF conditions or roamed during a call. This data helps correlate network conditions with the user's experience, making it essential for troubleshooting voice problems.
- ✗
Path Trace
Why it's wrong here
Path Trace is used to discover the forwarding path of packets between two endpoints, which can help identify routing loops or asymmetric paths. However, it does not provide voice quality metrics like jitter or packet loss. While path information can be useful, it is not a primary tool for diagnosing voice quality issues. The administrator needs application and client-specific data.
- ✗
Sensor Test
Why it's wrong here
Sensor Test runs synthetic tests from sensors to simulate client behavior and measure network performance. While it can provide valuable data on network readiness, it does not directly analyze the actual user's device or application performance. It is more for proactive monitoring and validation, not for troubleshooting an existing voice quality issue for a specific user.
