NEW QUESTION # 207
You have two Azure virtual machines named VM1 and VM2 that run Windows Server 2019. VM1 and VM2 each host a default Microsoft SQL Server 2019 instance. VM1 contains a database named DB1 that is backed up to a file named D:DB1.bak.
You plan to deploy an Always On availability group that will have the following configurations:
VM1 will host the primary replica of DB1.
VM2 will host a secondary replica of DB1.
You need to prepare the secondary database on VM2 for the availability group.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.

NEW QUESTION # 208
You have an Azure Synapse Analytics dedicated SQL pool named Pool1 and a database named DB1. DB1 contains a fact table named Table.
You need to identify the extent of the data skew in Table1.
What should you do in Synapse Studio?

A. Connect to the built-in pool and run DBCC CHECKALLOC.
B. Connect to Pool1 and query sys.dm_pdw_nodes_db_partition_stats.
C. Connect to Pool1 and run DBCC CHECKALLOC.
D. Connect to the built-in pool and query sys.dm_pdw_nodes_db_partition_stats.

Answer: D

Explanation:
Use sys.dm_pdw_nodes_db_partition_stats to analyze any skewness in the data.

NEW QUESTION # 209
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)?

A. Client Statistics
B. an actual execution plan
C. an estimated execution plan
D. Live Query Statistics

Answer: D

Explanation:
SQL Server Management Studio provides the ability to view the live execution plan of an active query. This live query plan provides real-time insights into the query execution process as the controls flow from one query plan operator to another. The live query plan displays the overall query progress and operator-level run-time execution statistics such as the number of rows produced, elapsed time, operator progress, etc. Because this data is available in real time without needing to wait for the query to complete, these execution statistics are extremely useful for debugging query performance issues.
