質問 # 163
DRAG DROP
You have an Azure SQL database that contains a table named Employees. Employees contains a column
named Salary.
You need to encrypt the Salary column. The solution must prevent database administrators from reading the
data in the Salary column and must provide the most secure encryption.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of
actions to the answer area and arrange them in the correct order.
Select and Place:
正解：
解説：
Section: [none]
Explanation:
Step 1: Create a column master key
Create a column master key metadata entry before you create a column encryption key metadata entry in the
database and before any column in the database can be encrypted using Always Encrypted.
Step 2: Create a column encryption key.
Step 3: Encrypt the Salary column by using the randomized encryption type.
Randomized encryption uses a method that encrypts data in a less predictable manner. Randomized encryption
is more secure, but prevents searching, grouping, indexing, and joining on encrypted columns.
Note: A column encryption key metadata object contains one or two encrypted values of a column encryption
key that is used to encrypt data in a column. Each value is encrypted using a column master key.
Incorrect Answers:
Deterministic encryption.
Deterministic encryption always generates the same encrypted value for any given plain text value. Using
deterministic encryption allows point lookups, equality joins, grouping and indexing on encrypted columns.
However, it may also allow unauthorized users to guess information about encrypted values by examining
patterns in the encrypted column, especially if there's a small set of possible encrypted values, such as True/
False, or North/South/East/West region.

質問 # 165
You have an instance of SQL Server on Azure Virtual Machines named SQL1. SQL1 contains a database named DB1.
You need to enable Transparent Data Encryption (TDE) for DB1.
Which three objects should you create in sequence? To answer, move the appropriate objects from the list of objects to the answer area and arrange them in the correct order.

Hotspot Question
You have an Azure SQL Database managed instance named sqldbmi1 that contains a database name Sales.
You need to initiate a backup of Sales.
How should you complete the Transact-SQL statement? 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: TO URL = 'https://storage1.blob.core.windows.net/blob1/Sales.bak' Native database backup in Azure SQL Managed Instance.
You can backup any database using standard BACKUP T-SQL command:
BACKUP DATABASE tpcc2501
TO URL = 'https://myacc.blob.core.windows.net/testcontainer/tpcc2501.bak' WITH COPY_ONLY Box 2: WITH COPY_ONLY SQLMI has "managed" everything, includes backup chain, so user can not break it's chain by using different method than COPY_ONLY.

質問 # 167
Task 8
You plan to perform performance testing of db1.
You need prevent db1 from reverting to the last known good query plan.
正解：
解説：
See the explanation part for the complete Solution.
Explanation:
To prevent db1 from reverting to the last known good query plan, you need to disable the automatic plan correction feature for the database. This feature is enabled by default and allows the Query Store to detect and fix plan performance regressions by forcing the last good plan1. However, if you want to test the performance of different plans without interference from the Query Store, you can turn off this feature by using the ALTER DATABASE SCOPED CONFIGURATION statement2.
Here are the steps to disable the automatic plan correction feature for db1:
Connect to db1 using SQL Server Management Studio, Azure Data Studio, or any other tool that supports Transact-SQL statements.
Open a new query window and run the following command: ALTER DATABASE SCOPED CONFIGURATION SET AUTOMATIC_TUNING (FORCE_LAST_GOOD_PLAN = OFF); GO This command will disable the automatic plan correction feature for db1 and allow the Query Optimizer to choose the best plan based on the current statistics and parameters3.
To verify that the automatic plan correction feature is disabled for db1, you can query the sys.
database_scoped_configurations catalog view. The value of the force_last_good_plan column should be 0 for db1.
These are the steps to disable the automatic plan correction feature for db1.
