QUESTION 35
You notice that a database server is responding slowly to queries.
You run the following dynamic management views (DMV) query on the server.
SELECT TOP (10) wait_type, wait_time_ms FROM sys.dm_os_wait_stats
ORDER BY wait_time_ms DESC;
The query returns a top wait type of SOS_SCHEDULER_YIELD.
You need to identify what is causing the server response issues.
Which resource should you investigate first?

A.    Disk
B.    CPU
C.    Memory
D.    Network

Answer: B

QUESTION 36
You attempt to query sys.dm_db_index_usage_stats to check the status on the indexes in the Contoso database.

“The user does not have permission to perform this action.”
You need to have the least amount of permissions granted to access the dynamic management views.
Which permissions should be granted?

D.    CREATE EXTERNAL ACCESS ASSEMBLY

Answer: B

QUESTION 37
You have been tasked to delete a number of Database Mail messages that have been sent.
You need to delete all the emails that were sent more than one month ago.
Which Transact-SQL statements should you run?

A.    DECLARE @OneMonthAgo datetime = DATEADD(mm,-1,GETDATE())
EXEC msdb.dbo.sysmail_delete_log_sp @OneMonthAgo
B.    DECLARE @OneMonthAgo datetime = DATEADD(mm,-1,GETDATE())
EXEC msdb.dbo.sysmail_delete_mailitems_sp @OneMonthAgo
C.    DECLARE @OneMonthAgo datetime = DATEADD(mm,-1,GETDATE())
EXEC msdb.dbo.sysmail_delete_log_sp @OneMonthAgo,’Success’
D.    DECLARE @OneMonthAgo datetime = DATEADD(mm,-1,GETDATE())
EXEC msdb.dbo.sysmail_delete_mailitems_sp @OneMonthAgo,’Sent’

Answer: D
Explanation:
sysmail_delete_mailitems_sp [ [ @sent_before = ] ‘sent_before’ ]
[ , [ @sent_status = ] ‘sent_status’ ]
Permanently deletes e-mail messages from the Database Mail internal tables.
[ @sent_before= ] ‘sent_before’
Deletes e-mails up to the date and time provided as the sent_before argument. sent_before is datetime with NULL as default. NULL indicates all dates.
[ @sent_status= ] ‘sent_status’
Deletes e-mails of the type specified by sent_status. sent_status is varchar(8) with no default. Valid entries are sent, unsent, retrying, and failed. NULL indicates all statuses.
Database Mail messages and their attachments are stored in the msdb database.
Messages should be periodically deleted to prevent msdb from growing larger than expected and to comply with your organizations document retention program.
Use the sysmail_delete_mailitems_sp stored procedure to permanently delete email messages from the Database Mail tables. An optional argument allows you to delete only older e- mails by providing a date and time. E-mails older than that argument will be deleted.
Another optional argument allows you to delete only e-mails of a certain type, specified as the sent_status argument. You must provide an argument either for @sent_before or @sent_status. To delete all messages, use @sent_before = getdate().

QUESTION 38
You administer a SQL Server 2008 database that contains a table name dbo.Sales, which contains the following table definition:
CREATE TABLE [dbo].[Sales](
[SalesID] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
[OrderDate] [datetime] NOT NULL,
[CustomerID] [int] NOT NULL,
[SalesPersonID] [int] NULL,
[CommentDate] [date] NULL);
This table contains millions of orders.
You run the following query to determine when sales persons comment in the dbo.Sales table:
SELECT SalesID,CustomerID,SalesPersonID,CommentDate
FROM dbo.Sales
WHERE CommentDate IS NOT NULL
AND SalesPersonID IS NOT NULL;
You discover that this query runs slow.
After examining the data, you find only 1% of rows have comment dates and the SalesPersonID is null on 10% of the rows.
You need to create an index to optimize the query.
The index must conserve disk space while optimizing your query.
Which index should you create?

A.    CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (CustomerID)
INCLUDE (CommentDate,SalesPersonID);
B.    CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (SalesPersonID)
INCLUDE (CommentDate,CustomerID);
C.    CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (CustomerID)
INCLUDE(CommentDate)
WHERE SalesPersonID IS NOT NULL;
D.    CREATE NONCLUSTERED INDEX idx1
ON dbo.Sales (CommentDate, SalesPersonID)
INCLUDE(CustomerID)
WHERE CommentDate IS NOT NULL;

Answer: D
