Correct Answer:

Explanation:
You are planning an Azure solution that will host production databases for a high-performance application.
The solution will include the following components:
Two virtual machines that will run Microsoft SQL Server 2016, will be deployed to different data centers in the same Azure region, and will be part of an Always On availability group.
SQL Server data that will be backed up by using the Automated Backup feature of the SQL Server IaaS Agent Extension (SQLIaaSExtension) You identify the storage priorities for various data types as shown in the following table.

Which storage type should you recommend for each data type? To answer, drag the appropriate storage types to the correct data types. Each storage type may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Correct Answer:

Explanation:
You have an on-premises server named Server1 that runs Windows Server and contains a Microsoft SQL Server database named DB1.
You have an Azure subscription.
You plan to migrate D81 to Azure.
You use the Azure Database Migration Service to assess DB1 and receive the assessment results shown in the following table.

You need to recommend a migration target for DB1. The migration target must meet the following requirements:
* Eliminate the need for post-migration operating system maintenance.
* Minimize administrative effort to prepare for the migration.
What should you recommend?
Correct Answer: A
Your on-premises network contains an Active Directory Domain Services (AD DS) domain. The domain contains a server named Server1. Server1 contains an app named App1 that uses AD DS authentication.
Remote users access App1 by using a VPN connection to the on-premises network.
You have a Microsoft Entra tenant that syncs with the AD DS domain by using Microsoft Entra Connect.
You need to ensure that the remote users can access App1 without using a VPN. The solution must meet the following requirements:
* Ensure that the users authenticate by using Azure Multi-Factor Authentication (MFA).
* Minimize administrative effort.
