You deploy Azure App Service Web Apps that connect to on-premises Microsoft SQL Server instances by using Azure ExpressRoute. You plan to migrate the
SQL Server instances to Azure.
Migration of the SQL Server instances to Azure must:
✑ Support automatic patching and version updates to SQL Server.
✑ Provide automatic backup services.
✑ Allow for high-availability of the instances.
✑ Provide a native VNET with private IP addressing.
✑ Encrypt all data in transit.
✑ Be in a single-tenant environment with dedicated underlying infrastructure (compute, storage).
You need to migrate the SQL Server instances to Azure.
Which Azure service should you use?

A. SQL Server in a Docker container running on Azure Container Instances (ACI)
B. SQL Server in Docker containers running on Azure Kubernetes Service (AKS)

No, it should be E. SQLMI doesn't support private IP address

At a high level, SQL Managed Instance is a set of service components. These components are hosted on a dedicated set of isolated virtual machines that run inside the customer's virtual network subnet. These machines form a virtual cluster. https://docs.microsoft.com/en-us/azure/azure-sql/managed-instance/connectivity-architecture-overview

the given answer is correct. Cannot have Azure SQL because it does not support VNET integration. SQL MI supports it.

The correct answer is D as one of the features related to Azure SQL Managed Instance is native Vnet integration - a native virtual network (VNet) implementation that addresses common security concerns https://docs.microsoft.com/en-us/azure/azure-sql/managed-instance/sql-managed-instance-paas-overview

E - Azure SQL Database with elastic pools would be correct as well since it can have a private endpoint in the VNET

I think it's a trick question. I have been studying for the exam and I don't remember reading from Azure SQL Database MI, but I have read from Azure SQL MI, and only the above three options (A, B and C) indicate SQL Server, and the question is about the options for migrate SQL Server instances. The most reasonable option (following the observation if it is DB or Server) is C (IaaS), but this does not support automatic updates and patches. I'll see if this question will be in my close exam.

C. SQL Server Infrastructure-as-a-Service (IaaS) virtual machine (VM) Requirement - Provide a native VNET with private IP addressing. This cannot be achieved on Azure SQL. With VNET integration you can restrict only the services within that VNET can reach DB, but still they have to reach the public endpoint of the DB (xx.database.windows.net) and not to a private IP.

This doesnt support automatic patching and version updates to SQL Server though does it?

Azure supports automated backup and automated patching for an Azure VM with SQL Server installed. It must be either SQL Server 2014 or 2016+, and with the SQL IaaS Agent extension in full management mode. A pair of VMs with AGs can support the multiple SQL instances required. Not strictly mentioned in the question, but reasonable implication is existing on-premises SQL licensing. With Software Assurance in a migration scenario both on-premises and cloud VMs are covered for 180 days. An Azure VM as the SQL AG failover server would not require a license if used purely for business continuity. Using SQL on an Azure VM with multiple instances could be the best solution. https://docs.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/automated-backup https://docs.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/automated-patching https://docs.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/sql-server-iaas-agent-extension-automate-management I think my answer will be C.

Exactly, on that link you mention it appears as capabilities this: Isolated environment (VNet integration, single tenant service, dedicated compute and storage) So the right answer is Managed Instance.

You guys seem to have missed the most important part of the question " Be in a single-tenant environment with dedicated underlying infrastructure (compute, storage)" Managed instances runs on shared infrastructure. Only IAAS can allow you to choose reserved instances
