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 sys.dm_os_waiting_tasks query.

B.
Create a sys.dm_exec_sessions query.

C.
Create a Performance Monitor Data Collector Set.

D.
Create a sys.dm_os_memory_objects query.

E.
Create a sp_configure ‘max server memory’ query.

F.
Create a SQL Profiler trace.

G.
Create asys.dm_os_wait_stats query.

H.
Create an Extended Event.

Explanation:
sys.dm_os_memory_objects returns memory objects that are currently allocated by SQL Server. You can use
sys.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
FROM sys.dm_os_memory_objects
GROUP BY type
ORDER BY ‘Bytes Used’ DESC;
GO
