問題 #111
You plan to create a table in an Azure Synapse Analytics dedicated SQL pool.
Data in the table will be retained for five years. Once a year, data that is older than five years will be deleted.
You need to ensure that the data is distributed evenly across partitions. The solutions must minimize the amount of time required to delete old data.
How should you complete the Transact-SQL statement? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all.
You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
答案：
解題說明：
Explanation:
Box 1: HASH
Box 2: OrderDateKey
In most cases, table partitions are created on a date column.
A way to eliminate rollbacks is to use Metadata Only operations like partition switching for data management.
For example, rather than execute a DELETE statement to delete all rows in a table where the order_date was in October of 2001, you could partition your data early. Then you can switch out the partition with data for an empty partition from another table.

問題 #115
You plan to deploy three instances of SQL Server on Azure Virtual Machines that will each contain 20 databases. You need to recommend a solution that meets the following requirements:
* Ensures that the deployment is highly available
* Minimizes administrative effort to manage users, logins, permissions, and SQL Server Agent jobs across the instances What should you include in the recommendation? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
答案：
解題說明：
Explanation:
Basic Concept: This question tests task automation for database administration, including which Azure or SQL mechanism can run repeatable maintenance and configuration work.
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 recommend a solution that meets the following requirements: * Ensures that the deployment is highly available * Minimizes administrative effort to manage users, logins, permissions, and SQL Server Agent jobs across the instances What should you inc 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.
