Explanation:

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:

Explanation:

Box 1: Full and log backups only
Make sure to take every backup on a separate backup media (backup files). Azure Database Migration Service doesn ' t support backups that are appended to a single backup file. Take full backup and log backups to separate backup files.
Box 2: WITH CHECKSUM
Azure Database Migration Service uses the backup and restore method to migrate your on-premises databases to SQL Managed Instance. Azure Database Migration Service only supports backups created using checksum.
Reference:
https://docs.microsoft.com/en-us/azure/dms/known-issues-azure-sql-db-managed-instance-online Basic Concept: This question tests choosing the correct Azure migration approach by matching the source platform, target service, downtime tolerance, and administrative effort.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to perform an online migration of DB1 to an Azure SQL Database managed instance by using Azure Database Migration Service.
Why the alternate choices are Wrong: The alternate selections would either use a migration tier that does not match the downtime requirement, choose a network resource that does not support the migration path, or add an unnecessary deployment component.

Reference:
https://docs.microsoft.com/en-us/sql/relational-databases/performance/live-query-statistics?view=sql-server- ver15 Basic Concept: This question tests database auditing and query visibility. DP-300 expects you to distinguish between collecting audit events, retaining logs, and analyzing query behavior.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You have an Azure SQL database.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.

Explanation:

Box 1: delete a row from Table1
Members of the db_datawriter fixed database role can add, delete, or change data in all user tables.
Box 2: db_datareader
Members of the db_datareader fixed database role can read all data from all user tables.
Reference:
https://docs.microsoft.com/en-us/sql/relational-databases/security/authentication-access/database-level-roles Basic Concept: This question tests implement a secure environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You have a Microsoft SQL Server database named DB1 that contains a table named Table1.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.

Explanation:

Step 1: Attach the SSISDB database
Step 2: Turn on the TRUSTWORTHY property and the CLR property
If you are restoring the SSISDB database to an SQL Server instance where the SSISDB catalog was never created, enable common language runtime (clr) Step 3: Open the master key for the SSISDB database Restore the master key by this method if you have the original password that was used to create SSISDB.
open master key decryption by password = ' LS1Setup! ' -- ' Password used when creating SSISDB ' Alter Master Key Add encryption by Service Master Key Step 4: Encrypt a copy of the mater key by using the service master key Reference:

Explanation:

Basic Concept: This question tests Azure monitoring and performance management, including which metric, log destination, or alerting behavior fits the operational requirement.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to monitor D81 by using SQL insights.
Why the alternate choices are Wrong: The alternate destinations or collection scopes miss part of the telemetry requirement: they either omit the server/pool/database layer or send data somewhere that does not support the requested analysis path.
