Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2Network AssuranceMedium

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?

  1. AWireless signal strength (RSSI)
  2. BOnboarding time
  3. CApplication response time
  4. DWired uplink utilization
Show answer & 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.
