Overview -

ADatum Corporation is a financial services company that has a main office in New York City.

Existing Environment. Licensing Agreement

ADatum has a Microsoft Volume Licensing agreement that includes Software Assurance.

Existing Environment. Network Infrastructure

ADatum has an on-premises datacenter and an Azure subscription named Sub1.

Sub1 contains a virtual network named Network1 in the East US Azure region.

The datacenter is connected to Network1 by using a Site-to-Site (S2S) VPN.

Existing Environment. Identity Environment

The on-premises network contains an Active Directory Domain Services (AD DS) forest.

The forest contains a single domain named corp.adatum.com.

The corp.adatum.com domain syncs with a Microsoft Entra tenant named adatum.com.

Existing Environment. Database Environment

The datacenter contains the servers shown in the following table.

DB1 and DB2 are used for transactional and analytical workloads by an application named App1.

App1 runs on Microsoft Entra hybrid joined servers that run Windows Server 2022. App1 uses Kerberos authentication.

DB3 stores compliance data used by two applications named App2 and App3.

DB3 performance is monitored by using Extended Events sessions, with the event_file target set to a file share on a local disk of SVR3.

Resource allocation for DB3 is managed by using Resource Governor.

Requirements. Planned Changes -

ADatum plans to implement the following changes:

• Deploy an Azure SQL managed instance named Instance1 to Network1.

• Migrate DB1 and DB2 to Instance1.

• Migrate DB3 to Azure SQL Database.

• Following the migration of DB1 and DB2, hand over database development to remote developers who use Microsoft Entra joined Windows 11 devices.

• Following the migration of DB3, configure the database to be part of an auto-failover group.

Requirements. Availability Requirements

ADatum identifies the following post-migration availability requirements:

• For DB1 and DB2, offload analytical workloads to a read-only database replica in the same Azure region.

• Ensure that if a regional disaster occurs, DB1 and DB2 can be recovered from backups.

• After the migration, App1 must maintain access to DB1 and DB2.

• For DB3, manage potential performance issues caused by resource demand changes by App2 and App3.

• Ensure that DB3 will still be accessible following a planned failover.

• Ensure that DB3 can be restored if the logical server is deleted.

• Minimize downtime during the migration of DB1 and DB2.

Requirements. Security Requirements

ADatum identifies the following security requirements for after the migration:

• Ensure that only designated developers who use Microsoft Entra joined Windows 11 devices can access DB1 and DB2 remotely.

• Ensure that all changes to DB3, including ones within individual transactions, are audited and recorded.

Requirements. Management Requirements

ADatum identifies the following post-migration management requirements:

• Continue using Extended Events to monitor DB3.

• In Azure SQL Database, automate the management of DB3 by using elastic jobs that have database-scoped credentials.

Requirements. Business Requirements

ADatum identifies the following business requirements:

• Minimize costs whenever possible, without affecting other requirements.

• Minimize administrative effort.

You need to recommend a process to automate the management of DB3. The solution must meet the management requirements.

What should be the first step of the process?

You have an Azure SQL database.

You identify a long running query.

You need to identify which operation in the query is causing the performance issue.

What should you use to display the query execution plan in Microsoft SQL Server Management Studio (SSMS)?

You're attempting to authenticate users in your Azure SQL Database. Which two methods can you use to authenticate against Azure SQL using identities in Entra ID?

You have an on-premises multi-tier application named App1 that includes a web tier, an application tier, and a Microsoft SQL Server tier. All the tiers run on Hyper-

V virtual machines.

Your new disaster recovery plan requires that all business-critical applications can be recovered to Azure.

You need to recommend a solution to fail over the database tier of App1 to Azure. The solution must provide the ability to test failover to Azure without affecting the current environment.

What should you include in the recommendation?

You have a SQL Server on Azure Virtual Machines instance named SQLVM1 that was deployed by using an Azure Marketplace SQL Server 2019 Enterprise image.

You need to change the Microsoft SQL Server instance on SQLVM1 to the Standard edition. The solution must ensure licensing compliance.

What should you do first?
