A network operations team uses Cisco DNA Center Assurance to monitor the health of their enterprise network. They notice a 'Client Experience' score for a specific location is consistently low, indicating poor Wi-Fi performance for users. Which of the following is NOT a direct metric or factor DNA Center Assurance typically uses to calculate the Client Experience score?
- AWireless signal strength (RSSI)
- BOnboarding time
- CApplication response time
- DWired uplink utilization
Show answer & explanationAnswer & explanation
Correct answer: D. Wired uplink utilization
Wired uplink utilization, while affecting overall network performance, is not a direct metric used to calculate the *Client Experience* score in Cisco DNA Center Assurance. The Client Experience score focuses on metrics directly impacting the end-user's wireless interaction, such as onboarding, application performance over Wi-Fi, and the quality of the wireless connection itself (RSSI, retries, etc.). Uplink utilization is a network device health metric, not a client-specific experience metric.
Why the other options are wrong
- A. Wireless signal strength (RSSI) is a fundamental indicator of the quality of a client's wireless connection and directly impacts experience.
- B. Onboarding time (association, authentication, DHCP) is a critical component of client experience.
- C. Application response time, especially for critical applications, directly impacts client experience.
DNA Center Client Experience Score
A metric in Cisco DNA Center Assurance that provides an aggregated view of end-user Wi-Fi performance, considering various factors directly impacting client connectivity and application usage.
- Aggregates multiple client-centric metrics.
- Factors include onboarding, connectivity, and application performance.
- Aims to quantify the quality of the wireless user's interaction.
Memory trick: Client Experience: Onboarding's key, apps must fly, signal strong, not just the wired tie.
