Explanation
The Cisco SD-WAN Cloud OnRamp solution rates SaaS application performance by calculating a quality-of-experience (QoE) score, which is a composite metric of various network factors.
Common mistakes.
- A. Monitoring packet loss, even for priority queues, is one component of performance measurement, but it does not represent the overall rating mechanism that encompasses multiple metrics.
- C. Measuring delay and jitter are critical metrics that contribute to the overall performance assessment, but they are individual parameters, not the complete method by which Cloud OnRamp rates application performance.
- D. Counting interface errors indicates physical or data link layer issues and is typically a low-level diagnostic, not the primary method for rating end-to-end SaaS application performance in an SD-WAN context.
