2 QUESTION: 81 You have a database named DB1. There is no memory-optimized file group in the database. You have a table and a stored procedure that were created by running the following Transact-SOL statements: The Employee table is persisted on disk. You add 2,000 records to the Employee table. You need to create an index that meets the following requirements: What should you do? A. Create a clustered index on the table. B. Create a nonclustered index on the table. C. Create a nonclustered filtered index on the table. D. Create a clustered column store index on the table. E. Create a nonclustered column store index on the table. F. Create a hash index on the table. Answer: B QUESTION: 82 DRAG DROP Case Study Background You have a database named HR1 that includes a table named Employee.

3 You have several read-only, historical reports that contain regularly changing totals. The reports use multiple queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate reports do not always run. You must monitor the database to identify issues that prevent the reports from running. You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires. Employee Table You use the following Transact-SQL statements to create, configure, and populate the Employee table: Application You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously: The application uses views to control access to data. Views must meet the following requirements: Both of the stored procedures experience blocking issues. UspB must not abort if UspA commits changes to a row before UspB commits changes to the same row. UspA must not abort if UspB commits changes to a row before UspA commits changes to the same row. Exhibit You need to specify the transaction isolation levels to enable row versioning. How should you complete the Transact-SQL statements? To answer, drag the Transact- SQL segments to the correct locations. Each Transact-SQL segment may be used once,

4 more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. Answer:

5 QUESTION: 83 HOTSPOT Background You have a database named HR1 that includes a table named Employee. You have several read-only, historical reports that contain regularly changing totals. The reports use multiple queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate reports do not always run. You must monitor the database to identify issues that prevent the reports from running. You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires. Employee Table You use the following Transact-SOL statements to create, configure, and populate the Employee table:

6 Application You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously: The application uses views to control access to data. Views must meet the following requirements: Users must only be able to modify data in the Employee table by using the vwemployee view. You must prevent users from viewing the view definition in catalog views. You need to identify the view attribute to use when creating vwemployee. Exhibit In the table below, identify the attributes that you must use. NOTE: Make only one selection in each column.

7 Answer: QUESTION: 84 Background You have a database named HR1 that includes a table named Employee. You have several read-only, historical reports that contain regularly changing totals. The reports use multiple queries to estimate payroll expenses. The queries run concurrently. Users report that the payroll estimate reports do not always run. You must monitor the database to identify issues that prevent the reports from running. You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires. Employee Table You use the following Transact-SOL statements to create, configure, and populate the Employee table:

8 Application You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously: The application uses views to control access to data. Views must meet the following requirements: You are analyzing the performance of the database environment. You discover that locks that are held for a long period of time as the reports are generated. You need to generate the reports more quickly. The database must not use additional resources. Exhibit What should you do? A. Update the transaction level of the report query session to READPAST. B. Modify the report queries to use the UNION statement to combine the results of two or more queries. C. Set the READ_COMMITTED_SNAPSHOT database option to ON. D. Update the transaction level of the report query session to READ UNCOMMITTED. Answer: C

You must monitor the database to identify issues that prevent the reports from running. You plan to deploy the application to a database server that supports other applications. You must minimize the amount of storage that the database requires. Employee Table You use the following Transact-SOL statements to create, configure, and populate the Employee table: Application You have an application that updates the Employees table. The application calls the following stored procedures simultaneously and asynchronously: The application uses views to control access to data. Views must meet the following requirements: You view the Deadlock Graph as shown in the exhibit. (Click the Exhibit button.) Use the drop-down menus to select the answer choice that answers each question based on the information presented in the graphic. NOTE: Each correct selection is worth one point.
