- A.Create an assessment with performance-based sizing, a one-month performance history, and a comfort factor
- B.Use Azure Advisor right-sizing recommendations before migration
- C.Size VMs to match each server's configured vCPU and memory exactly
- D.Create an assessment with as on-premises sizing
Show answer and explanation
Correct answer: A. Create an assessment with performance-based sizing, a one-month performance history, and a comfort factor
Why: Performance-based sizing uses utilization data collected by Azure Migrate over the chosen period, and the comfort factor adds headroom for peaks and growth. As on-premises sizing, like matching configured vCPU and memory, copies the overprovisioning into Azure. Azure Advisor analyzes resources already running in Azure, not servers that have not been migrated.
