Developing SQL Databases — Question 169

Note: This question is part of a series of questions that use the same or similar answer choices. An Answer choice may be correct for more than one question in the series. 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 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?

Answer options

• 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.

Correct answer: D

Explanation

The correct answer is D because creating a sys.dm_os_memory_objects query allows you to analyze memory usage by SQL Server processes, which is essential for understanding performance under normal load. The other options either focus on wait statistics, session information, or general monitoring tasks that do not specifically establish a baseline for memory usage.
