After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have a database that is 130 GB and contains 500 million rows of data.
Granular transactions and mass batch data imports change the database frequently throughout the day.
Microsoft SQL Server Reporting Services (SSRS) uses the database to generate various reports by using several filters.
You discover that some reports time out before they complete.
You need to reduce the likelihood that the reports will time out.
Solution: You create a file group for the indexes and a file group for the data files. You store the files for each file group on separate disks.
Does this meet the goal?

• A.Yes
• B.No

Note: This question is part of a series of questions that present the same scenario. Each question in this series contains a unique solution. Determine whether the solution meets the stated goals.
You are developing a new application that uses a stored procedure. The stored procedure inserts thousands of records as a single batch into the Employees table.
Users report that the application response time has worsened since the stored procedure was updated. You examine disk-related performance counters for the Microsoft SQL Server instance and observe several high values that include a disk performance issue. You examine wait statistics and observe an unusually high WRITELOG value.
You need to improve the application response time.
Solution: You replace the stored procedure with a user-defined function.
Does the solution meet the goal?

• A.Yes
• B.No

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
You have a database that contains a table named Employees. The table stores information about the employees of your company.
You need to implement and enforce the following business rules:
- Limit the values that are accepted by the Salary column.
- Prevent salaries less than $15,000 and greater than $300,000 from being entered.
- Determine valid values by using logical expressions.
- Do not validate data integrity when running DELETE statements.
Solution: You implement cascading referential integrity constraints on the table.
Does the solution meet the goal?

• A.Yes
• B.No

You have a database named DB1. The database does not have a memory optimized filegroup.
You create a table by running the following Transact-SQL statement:

The table is currently used for OLTP workloads. The analytics user group needs to perform real-time operational analytics that scan most of the records in the table to aggregate on a number of columns.
You need to add the most efficient index to support the analytics workload without changing the OLTP application.
What should you do?

• A.Create a clustered columnstore index on the table.
• B.Create a nonclustered columnstore index on the table.
• C.Create a hash index on the table.
• D.Create a nonclustered filtered index on the table.
• E.Create a nonclustered index on the table.
• F.Create a clustered index on the table.

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 collect query performance data while minimizing the performance impact on the SQL Server.
What should you do?

• A.Create a sys.dm_os_waiting_tasks query.
• B.Create a Performance Monitor Data CollectorSet.
• C.Create a sys.dm_exec_sessions query.
• D.Create a SQL Profiler trace.
• E.Create a sys.dm_os_wait_stats query.
• F.Create a sp_configure 'max server memory' query.
• G.Create a sys.dm_os_memory_objects query.
• H.Create an Extended Event.
