✓ Correct answers
- Measure sign-in bursts and profile/storage latency as well as steady-state host performance.
- Run representative applications with the expected peak concurrent user mix.
Measure the actual workload, concurrency and user experience across steady-state and burst periods. Use those results to set capacity and limits. Option explanations: A. Test one idle session and multiply its CPU usage by the total licensed user count.: An idle sample and assigned-user count do not represent concurrent demand or contention. B. Measure sign-in bursts and profile/storage latency as well as steady-state host performance.: Transient sign-in and external dependencies can dominate the user experience. C. Run representative applications with the expected peak concurrent user mix.: Realistic concurrent workload exposes CPU, memory and application demand. D. Use only the largest available VM size as evidence that all response targets will be met.: Size alone does not prove application, storage and connection performance.
