* Transparent Data Encryption (TDE) is a special case of encryption using a symmetric key. TDE
encrypts an entire database using that symmetric key called the database encryption key. The
database encryption key is protected by other keys or certificates which are protected either by the
database master key or by an asymmetric key stored in an EKM module.
* SQL Server provides the following mechanisms for encryption:
Transact-SQL functions
Asymmetric keys
Symmetric keys
Transparent Data Encryption

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.4 Note: This question is part of a series of questions that use the same scenario. For your

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. sp_lock
B. sys.dm_tran_active_snapshot_database_transactions
C. sp_updatestats
D. sys.dm_os_waiting_tasks
Answer: A

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.
