The company’s migration plan states that only Platform as a Service (PaaS) solutions must be used in Azure. You need to deploy an Azure environment that meets the company migration plan. Solution: You create an Azure virtual machines, Azure SQL databases, and Azure Storage accounts. Does this meet the goal?

Answer options

Correct Answer:

Explanation

The proposed solution does not meet the goal because it includes Azure Virtual Machines. Azure Virtual Machines are an Infrastructure as a Service (IaaS) offering, where the user is responsible for managing the operating system and software. The company's migration plan explicitly states that only Platform as a Service (PaaS) solutions must be used. While Azure SQL Database and Azure Storage are considered PaaS, the inclusion of an IaaS component violates the core requirement of the migration plan. Therefore, the entire solution is non-compliant.

Why Incorrect

A. Yes: This is incorrect. The solution includes Azure Virtual Machines, which is an IaaS service, directly contradicting the requirement to use only PaaS solutions.
