You need to collect data from the following two sources:
* The performance counters of the operating system
* Microsoft SQL Server events
You must analyze the two datasets side-by side by using a single tool.
Solution: You use dynamic management views and SQL Server Profiler to collect performance data.
You use SQL Server Management Studio (SSMS) to analyze the data.
Does this meet the goal?
A. No
B. Yes
Answer: B
QUESTION NO: 3

Each question independent of the other questions in this series. Information and details provided in a question apply only to that question.
You are a database developer for a company. The company has a server that has multiple physical disks. The disks are not part of a RAID array. The server hosts three Microsoft SQL Server instances.
There are many SQL jobs that run during off-peak hours.
You must monitor the SQL Server instances in real time and optimize the server to maximize throughput, response time, and overall SQL performance.
You need to create a baseline set of metrics to report how the computer running SQL Server operates under normal load. The baseline must include the resource usage associated with the server processes.
What should you do?
A. Create a SQL Profiler trace.
B. Create a sp_configure 'max server memory' query.
C. Create a sys.dm_os_memory_objects query.
D. Create a Performance Monitor Data Collector Set.
E. Create asys.dm_os_wait_stats query.
F. Create an Extended Event.
G. Create a sys.dm_os_waiting_tasks query.
H. Create a sys.dm_exec_sessions query.
Answer: C
Explanation
sys.dm_os_memory_objects returns memory objects that are currently allocated by SQL Server. You can usesys.dm_os_memory_objects to analyze memory use and to identify possible memory leaks.
Example: The following example returns the amount of memory allocated by each memory object type.
SELECT SUM (pages_in_bytes) as 'Bytes Used', type
FROMsys.dm_os_memory_objects
GROUP BY type
ORDER BY 'Bytes Used' DESC;
GO
QUESTION NO: 4
You use Microsoft SQL Server Profile to evaluate a query named Query1. The Profiler report indicates the following issues:
* At each level of the query plan, a low total number of rows are processed.
* The query uses many operations. This results in a high overall cost for the query.
You need to identify the information that will be useful for the optimizer.
What should you do?
A. Start a SQL Server Profiler trace for the event class Performance statistics in the Performance event category.
B. Create one Extended Events session with the sqlserver.error_reported event added.
C. Start a SQL Server Profiler trace for the event class Soft Warnings in the Errors and Warnings event category.
D. Create one Extended Events session with the sqlserver.missing_column_statistics event added.
Answer: A
Explanation
The Performance Statistics event class can be used to monitor the performance of queries, stored procedures, and triggers that are executing. Each of the six event subclasses indicates an event in the lifetime of queries, stored procedures, and triggers within the system. Using the combination of these event subclasses and the associated sys.dm_exec_query_stats, sys.dm_exec_procedure_stats and sys.dm_exec_trigger_stats dynamic management views, you can reconstitute the performance history of any given query, stored procedure, or trigger.
