You have a Microsoft SQL Server 2017 server.
You need to migrate the server to Azure. The solution must meet the following requirements:
* Ensure that the latest version of SQL Server is used.
* Support the SQL Server Agent service.
Minimize administrative effort.
What should you use?
Correct Answer: A
Basic Concept: This question tests choosing the correct Azure migration approach by matching the source platform, target service, downtime tolerance, and administrative effort.
Why A is Correct: SQL Server on Azure Virtual Machines is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario.
The scenario asks for: You need to migrate the server to Azure. That makes SQL Server on Azure Virtual Machines the option that satisfies the required Azure SQL layer and operational outcome.
Why B is Wrong: Azure SQL Database is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It mismatches the target platform, migration method, compute tier, or deployment model described in the scenario, so it would not satisfy the workload as stated.
Why C is Wrong: Elastic pools let multiple Azure SQL databases share a fixed pool of resources, which is cost-effective when individual database usage is variable and unpredictable. It applies to a different Azure data-platform design than the one the question is testing.
Why D is Wrong: Azure SQL Managed Instance is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It would solve a neighboring problem, but not the deployment, sizing, or migration requirement in this item.
