Explanation:
A SQL Server Agent proxy defines the security context for a job step. A proxy provides
SQL Server Agent with access to the security credentials for a Microsoft Windows user.
Each proxy can be associated with one or more subsystems. A job step that uses the proxy can access
the specified subsystems by using the security context of the Windows user.
Before SQL Server Agent runs a job step that uses a proxy, SQL Server Agent impersonates the
credentials defined in the proxy, and then runs the job step by using that security context.

NO.2 Your database contains a table named Purchases. The table includes a DATETIME column
named PurchaseTime that stores the date and time each purchase is made. There is a non- clustered
index on the PurchaseTime column. The business team wants a report that displays the total number
of purchases made on the current day. You need to write a query that will return the correct results
in the most efficient manner.
Which Transact-SQL query should you use?
A. SELECT COUNT(*)FROM PurchasesWHERE PurchaseTime = CONVERT(DATE, GETDATE())
B. SELECT COUNT(*)FROM PurchasesWHERE PurchaseTime = GETDATE()
C. SELECT COUNT(*)FROM PurchasesWHERE PurchaseTime >= CONVERT(DATE, GETDATE())AND
PurchaseTime <DATEADD(DAY, 1, CONVERT(DATE, GETDATE()))
D. SELECT COUNT(*)FROM PurchasesWHERE CONVERT(VARCHAR, PurchaseTime, 112)
=CONVERT(VARCHAR, GETDATE(), 112)
Answer: C

Explanation:
SQL Server Extended Events has a highly scalable and highly configurable architecture that allows
users to collect as much or as little information as is necessary to troubleshoot or identify a
performance problem.
Extended Events is a light weight performance monitoring system that uses very few performance
resources.
A SQL Server Extended Events session is created in the SQL Server process hosting the
Extended Events engine.
