    Case Study 5 - ADatum Corporation
    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.
    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.
    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.
    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.
    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.
    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.
    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.
    Business Requirements
    ADatum identifies the following business requirements:
    - Minimize costs whenever possible, without affecting other requirements.
    - Minimize administrative effort.
    You need to recommend a solution to ensure that the performance of DB3 is optimized after the migration to Azure SQL Database. The solution must meet availability requirements.
    What should you include in the recommendation?

    Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
    After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
    You have an Azure Data Lake Storage account that contains a staging zone.
    You need to design a daily process to ingest incremental data from the staging zone, transform the data by executing an R script, and then insert the transformed data into a data warehouse in Azure Synapse Analytics.
    Solution: You use an Azure Data Factory schedule trigger to execute a pipeline that executes mapping data flow, and then inserts the data into the data warehouse.
    Does this meet the goal?
