  • A. The customer’s on-call engineer
  • B. The cloud provider

  • B. The Azure pricing calculator

The pricing calculator (or Cost Management estimates) models SKU and region cost before you deploy.

  • B. Resource groups can apply lifecycle and access boundaries
  • C. A virtual machine must exist in every resource group in the tenant

  • A. A storage account
  • B. A virtual network
  • C. An Azure AD tenant
  • D. A public IP prefix used as a subnet

  • A. A VM you patch yourself
  • B. Azure SQL Database
  • C. Buying a rack in a colocation cage
