質問 # 107
You have an Azure SQL database.
You discover that the plan cache is full of compiled plans that were used only once.
You run the select * from sys.database_scoped_configurationsTransact-SQL command and receive the results shown in the following table.
You need relieve the memory pressure.
What should you configure?
正解：D
解説：
OPTIMIZE_FOR_AD_HOC_WORKLOADS = { ON | OFF }
Enables or disables a compiled plan stub to be stored in cache when a batch is compiled for the first time. The default is OFF. Once the database scoped configuration OPTIMIZE_FOR_AD_HOC_WORKLOADS is enabled for a database, a compiled plan stub will be stored in cache when a batch is compiled for the first time.
Plan stubs have a smaller memory footprint compared to the size of the full compiled plan.
Incorrect Answers:
A: LEGACY_CARDINALITY_ESTIMATION = { ON | OFF | PRIMARY }
Enables you to set the query optimizer cardinality estimation model to the SQL Server 2012 and earlier version independent of the compatibility level of the database. The default is OFF, which sets the query optimizer cardinality estimation model based on the compatibility level of the database.
B: QUERY_OPTIMIZER_HOTFIXES = { ON | OFF | PRIMARY }
Enables or disables query optimization hotfixes regardless of the compatibility level of the database. The default is OFF, which disables query optimization hotfixes that were released after the highest available compatibility level was introduced for a specific version (post-RTM).

質問 # 108
You have an Azure SQL database.
You need to identify whether a delayed query execution is associated to a RESOURCE wait.
How should you complete the Transact -SQL statement? To answer, select the appropriate option in the answer area.
NOTE: Each correct selection is worth one point.
正解：
解説：
Explanation:
Basic Concept: This question tests monitor, configure, and optimize database resources 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 need to identify whether a delayed query execution is associated to a RESOURCE wait.
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.
質問 # 109
You have an on-premises Microsoft SQL Server 2016 server named Server1 that contains a database named DB1.
You need to perform an online migration of DB1 to an Azure SQL Database managed instance by using Azure Database Migration Service.
How should you configure the backup of DB1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
正解：
解説：
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.
質問 # 110
You have a Microsoft SQL Server 2017 server that hosts five databases.
You Plan to migrate the databases to Azure.
You need to recommend a solution that meets the following requirements:
* Automatically scales compute based on the workload demand
* Provides per-second billing
What should you include in the recommendation? To answer, select the appropriate options in the answer area.
正解：
解説：

質問 # 111
You are monitoring an Azure Stream Analytics job.
You discover that the Backlogged input Events metric is increasing slowly and is consistently non-zero.
You need to ensure that the job can handle all the events.
What should you do?
正解：C
解説：
Explanation
Backlogged Input Events: Number of input events that are backlogged. A non-zero value for this metric implies that your job isn't able to keep up with the number of incoming events. If this value is slowly increasing or consistently non-zero, you should scale out your job, by increasing the SUs.
