NEW QUESTION # 23
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 which configuration to perform twice to enable access to the primary and secondary replicas of DB3. The solution must meet the availability requirements.
What should you recommend?
Answer: C
NEW QUESTION # 24
You have an Azure Data Factory instance named ADF1 and two Azure Synapse Analytics workspaces named WS1 and WS2.
ADF1 contains the following pipelines:
P1:Uses a copy activity to copy data from a nonpartitioned table in a dedicated SQL pool of WS1 to an Azure Data Lake Storage Gen2 account P2:Uses a copy activity to copy data from text-delimited files in an Azure Data Lake Storage Gen2 account to a nonpartitioned table in a dedicated SQL pool of WS2 You need to configure P1 and P2 to maximize parallelism and performance.
Which dataset settings should you configure for the copy activity of each pipeline? To answer, select the appropriate options in the answer area.
Answer:
Explanation:
Explanation
Graphical user interface, text, chat or text message Description automatically generated
P1: Set the Partition option to Dynamic Range.
The SQL Server connector in copy activity provides built-in data partitioning to copy data in parallel.
P2: Set the Copy method to PolyBase
Polybase is the most efficient way to move data into Azure Synapse Analytics. Use the staging blob feature to achieve high load speeds from all types of data stores, including Azure Blob storage and Data Lake Store.
(Polybase supports Azure Blob storage and Azure Data Lake Store by default.) Reference:

NEW QUESTION # 25
You have an Azure Synapse Analytics dedicated SQL pool.
You run PDW_SHOWSPACEUSED('dbo.FactInternetSales'); and get the results shown in the following table.
Which statement accurately describes the dbo.FactInternetSales table?
Answer: A
Explanation:
The rows per distribution can vary up to 10% without a noticeable impact on performance. Here the distribution varies more than 10%. It is skewed.
Note: SHOWSPACEUSED displays the number of rows, disk space reserved, and disk space used for a specific table, or for all tables in a Azure Synapse Analytics or Parallel Data Warehouse database.
This is a very quick and simple way to see the number of table rows that are stored in each of the
60 distributions of your database. Remember that for the most balanced performance, the rows in your distributed table should be spread evenly across all the distributions.
ROUND_ROBIN distributed tables should not be skewed. Data is distributed evenly across the nodes by design.

NEW QUESTION # 26
You have an on-premises Microsoft SQL Server 2016 instance that hosts a database named db1. You have an Azure subscription that contains an Azure SQL managed instance named Mil.
You plan to perform an online migration of db1 to MM by using Azure Database Migration Service.
You need to create the backups for the migration. The solution must minimize the number of backup files created.
Which type of backups should you create, and how should you store the backups? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
