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

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

You need to resolve the performance issue.
Solution: You rebuild the clustered index.
Does the solution meet the goal?
A. No
B. Yes
Answer: A
Explanation
The query uses the nonclustered index, so improving the clustered index will not help.
We should update statistics for the nonclustered index.
