More than one answer choice may achieve the goal. Select the BEST answer.

70-764 学校
Explanation:
An application role is a database principal that enables an application to run with its own, user-like
permissions. You can use application roles to enable access to specific data to only those users who
connect through a particular application. Unlike database roles, application roles contain no
members and are inactive by default.
Reference: Application Roles
NO.2 You have a SQL Server instance on a server named Server1.
You need to recommend a solution to perform the following tasks every week:
* Rebuild the indexes by using a new fill factor.
* Run a custom T-SQL command.
* Back up the databases.
What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.
A. A trigger
B. An alert
C. A system policy
D. Windows PowerShell
E. A maintenance plan
Answer: E
Explanation:
Maintenance plans create a workflow of the tasks required to make sure that your database is
optimized, regularly backed up, and free of inconsistencies.

NO.3 Note: This question is part of a series of questions that use the same scenario. For your
convenience, the scenario is repeated in each question. Each question presents a different goal and
answer choices, but the text of the scenario is exactly the same in each question in this series.
You are a database administrator for a company that has an on-premises Microsoft SQL
Server environment and Microsoft Azure SQL Database instances. The environment hosts several
customer databases, and each customer uses a dedicated instance. The environments that you
manage are shown in the following table.
You need to monitor WingDB and gather information for troubleshooting issues.
What should you use?
A. sys.dm_os_waiting_tasks
B. sys.dm_tran_active_snapshot_database_transactions
C. sp_updatestats
D. sp_lock
Answer: D
70-764 訓練
Explanation:
The sp_lock system stored procedure is packaged with SQL Server and will give you insight into the
locks that are happening on your system. This procedure returns much of its information from the
syslock info in the master database, which is a system table that contains information on all granted,
converting, and waiting lock requests.
Note: sp_lock will be removed in a future version of Microsoft SQL Server. Avoid using this feature in
new development work, and plan to modify applications that currently use this feature. To obtain
information about locks in the SQL Server Database Engine, use the sys.dm_tran_locks dynamic
management view.
sys.dm_tran_locks returns information about currently active lock manager resources in
SQL Server 2008and later. Each row represents a currently active request to the lock manager for a
lock that has been granted or is waiting to be granted.

procedures/sp-lock-transact-sql
NO.4 You have two SQL Server 2016 instances named SQLDev and SQLProd.
You plan to create a new database on SQLProd that will use SQL Server Authentication.
You need to ensure that when the new database is copied from SQLProd to SQLDev, users can
connect to the database on SQLDev even if they do not have a login on the
SQLDev instance.
What should you use?
More than one answer choice may achieve the goal. Select the BEST answer.
A. SQL Server Analysis Services (SSAS) scripts
B. Extended Events
C. Contained database
D. Triggers
E. SQL Server Integration Services (SSIS) scripts
Answer: C
Explanation:
A fully contained database includes all the settings and metadata required to define the database and
has no configuration dependencies on the instance of the SQL Server
Database Engine where the database is installed.
