A pilot supports 30 concurrent users on each 8-vCPU host. A new pool needs 120 concurrent users plus one-host failure tolerance. Other VMs already consume 16 vCPUs from the same relevant regional VM-family quota. What minimum family quota accommodates the design?

✓ Correct answer

• 56 vCPUs.

Four hosts serve the peak; a fifth provides the failure margin. The new fleet needs 5 × 8 = 40 vCPUs, so the quota must accommodate 40 + 16 = 56. Quota still does not reserve physical capacity. Option explanations: A. 56 vCPUs.: Five hosts need 40 vCPUs, and the existing consumption adds 16. B. 48 vCPUs.: Four new hosts plus existing usage fit 48, but four lack the required one-host failure margin. C. 40 vCPUs.: This covers the new pool but omits the existing 16-vCPU consumption. D. 64 vCPUs.: This provides extra quota but is not the minimum for the stated design.
