  Azure App Service is a PaaS offering.

  Azure Virtual Machines running Microsoft SQL Server are Infrastructure as a Service (IaaS).

  They require management of the operating system and database software, which violates the "PaaS only" requirement.

  WHY THIS IS INCORRECT

  The solution mixes PaaS and IaaS:

  Azure App Service = PaaS

  Azure Virtual Machines with SQL Server = IaaS

  Because the company policy requires ONLY PaaS services, the presence of virtual machines makes the solution invalid.

  CORRECT PaaS ALTERNATIVES

  To satisfy the requirement, SQL Server on virtual machines should be replaced with a PaaS database service such as:

  Azure SQL Database

  Azure SQL Managed Instance

  FINAL ANSWER

  No - The solution does NOT meet the requirement because Azure Virtual Machines run SQL Server as IaaS, not PaaS.

• Question 246:

  Fill in the blank

  If an Azure virtual machine has a status of Stopped (deallocated), you will continue to pay for (_______________)

  storage

• Question 247:

  DRAG DROP

  Match the cloud computing benefits to the appropriate requirements.

  To answer, drag the appropriate benefit from the column on the left to its requirement on the right. Each benefit may be used once, more than once, or not at all.

  NOTE: Each correct match is worth one point.

  Select and Place:

  

  

  Explanation:

  Box 1: High availability

  Box 2: Geo-distribution You can direct traffic with a geo-distributed app using Azure and Azure Stack Hub. Use the geo-distributed apps pattern

  With the geo-distributed pattern, your app spans regions. You can default to the public cloud, but some of your users may require that their data remain in their region. You can direct users to the most suitable cloud based on their requirements.

  Box 3: Scalability

• Question 248:

  Your company has a Software Assurance agreement that includes Microsoft SQL Server licenses.

  You plan to deploy SQL Server on Azure virtual machines.

  What should you do to minimize licensing costs for the deployment?

  A. Deallocate the virtual machines during off hours.
  B. Use Azure Hybrid Benefit.
  C. Configure Azure Cost Management budgets.
  D. Use Azure reservations.
  B. Use Azure Hybrid Benefit.

  Azure Hybrid Benefit (AHB) allows using existing SQL Server licenses with Software Assurance to run SQL Server in Azure VMs.-Reduces cost of SQL Server licensing in Azure.-Applies to both SQL Server and Windows Server licenses. Incorrect Options: Deallocate the virtual machines during off hours: Only reduces compute costs, not SQL Server licensing costs.-Configure Azure Cost Management budgets: Budgets monitor costs but do not reduce licensing fees.-Use Azure reservations: Reservations reduce VM compute costs but not SQL Server licensing fees.
