QUESTION 14
You administer a Microsoft SQL Server 2012 database.
Users report that an application that accesses the database displays an error, but the error does not provide meaningful information.
No entries are found in the SQL Server log or Windows event logs related to the error.
You need to identify the root cause of the issue by retrieving the error message.
What should you do?

A.    Create an Extended Events session by using the sqlserver.error_reported event.
B.    Create a SQL Profiler session to capture all ErrorLog and EventLog events.
C.    Flag all stored procedures for recompilation by using sp_recompile.
D.    Execute sp_who.

Answer: A
Explanation:
http://msdn.microsoft.com/en-us/library/bb630282.aspx

QUESTION 15
You administer a Microsoft SQL Server 2012 server.
One of the databases on the server supports a highly active OLTP application.
Users report abnormally long wait times when they submit data into the application.
You need to identify which queries are taking longer than 1 second to run over an extended period of time.
What should you do?

A.    use SQL Profiler to trace all queries that are processing on the server.
Filter queries that have a Duration value of more than 1,000.
B.    Use sp_configure to set a value for blocked process threshold.
Create an extended event session.
C.     Use the Job Activity monitor to review all processes that are actively running.
Review the Job History to find out the duration of each step.
D.    Run the sp_who command from a query window.
E.    Run the DBCC TRACEON 1222 command from a query window and review
the SQL Server event log.

Answer: E
Explanation:
Verified the SQL Profiler and DBCC answers as correct. However, while Profiler will show this information, the best practice with Profiler is to use it short-term.
The question specifically states “over an extended period of time”.
That means Profiler wouldn’t be the best tool for this scenario.
Therefore, DBCC would be the best answer.
