QUESTION 10
Note: This questions is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You deploy Microsoft SQL Server to a virtual machine in Azure. You distribute the database files and filegroups across multiple Azure storage disks. You must be able to manage the databases as individual entities by using SQL Server Management Studio. All data in the databases must be stored encrypted. Backups must be encrypted by using the same key as the live copy of the database. You need to secure the data. What should you implement?

A.    transport-level encryption
B.    cell-level encryption
C.    Transparent Data Encryption
D.    Always Encrypted
E.    Encrypting File System
F.    BitLocker
G.    dynamic data masking

Answer: C
Explanation:
Transparent data encryption (TDE) encrypts your databases, associated backups, and transaction log files at rest without requiring changes to your applications. TDE encrypts the storage of an entire database by using a symmetric key called the database encryption key. In SQL Database the database encryption key is protected by a built-in server certificate. The built-in server certificate is unique for each SQL Database server.

QUESTION 11
You are deploying a Microsoft SQL Server database that will support a mixed OLTP and OLAP workload. The target virtual machine has four CPUs. You need to ensure that reports do not use all available system resources. What should you do?

A.    Enable Auto Close.
B.    Increase the value for the Minimum System Memory setting.
C.    Set MAXDOP to half the number of CPUs available.
D.    Increase the value for the Minimum Memory per query setting.

Answer: C
Explanation:
When an instance of SQL Server runs on a computer that has more than one microprocessor or CPU, it detects the best degree of parallelism, that is, the number of processors employed to run a single statement, for each parallel plan execution. You can use the max degree of parallelism option to limit the number of processors to use in parallel plan execution.

QUESTION 12
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets stated goals.
You manage a Microsoft SQL Server environment with several databases. You need to ensure that queries use statistical data and do not initialize values for local variables.
Solution: You enable the LEGACY_CARDINALITY_ESTIMATION option for the databases.
Does the solution meet the goal?

A.    Yes
B.    No

Answer: B
