Question 1:

You have a database named DB1 that is configured to use the full recovery model. You have a full daily backup job that runs at 02:00. The job backs up data from DB1 to the file


You need to restore the DB1 database to the point in time of May 25, 2016 at 02:23 and ensure that the database is functional and starts to accept connections.

Which Transact-SQL statement should you run?

A. Option A

B. Option B

C. Option C

D. Option D

Correct Answer: B

Question 2:

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 is independent of the other questions in this series.

Information and details provided in a question apply only to that question.

You need to examine information about logins, CPU times, and Disk I/O on a particular database in Microsoft Azure.

What should you use?

A. Activity Monitor

B. Sp_who3

C. SQL Server Management Studio (SSMS) Object Explorer

D. SQL Server Data Collector

E. SQL Server Data Tools (SSDT)

F. SQL Server Configuration Manager

Correct Answer: A

Activity Monitor displays information about SQL Server processes and how these processes affect the current instance of SQL Server. Activity Monitor is a tabbed document window with the following expandable and collapsible panes: Overview, Active User Tasks, Resource Waits, Data File I/O, and Recent Expensive Queries.

The Activity User Tasks Pane shows information for active user connections to the instance, including the following column:


Login: The SQL Server login name under which the session is currently executing.

The Recent Expensive Queries Pane shows information about the most expensive queries that have been run on the instance over the last 30 seconds, including the following column:


CPU (ms/sec): The rate of CPU use by the query


Question 3:

You have a database that stores information for a shipping company. You create a table named Customers by running the following Transact-SQL statement. (Line numbers are included for reference only.)

You need to ensure that salespeople can view data only for the customers that are assigned to them. Which Transact-SQL segment should you insert at line 07?

A. RETURNS varchar(20)WITH Schemabinding

B. RETURNS dbo.CustomersORDER BY @salesPerson

C. RETURNS tableORDER BY @salesPerson

D. RETURNS tableWITH Schemabinding

Correct Answer: D

The return value can either be a scalar (single) value or a table. SELECT 1 just selects a 1 for every row, of course. What it\’s used for in this case is testing whether any rows exist that match the criteria: if a row exists that matches the WHERE clause, then it returns 1, otherwise it returns nothing. Specify the WITH SCHEMABINDING clause when you are creating the function. This ensures that the objects referenced in the function definition cannot be modified unless the function is also modified.

Question 4:

You use SQL Server 2016 to maintain the data used by applications at your company.

You want to execute two statements.

You need to guarantee that either both statements succeed, or both statements fail together as a batch.

Which code should you use?

A. Option A

B. Option B

C. Option C

D. Option D

E. Option E

Correct Answer: D


Reference: TRY…CATCH (Transact-SQL)

Question 5:

You are designing a SQL Server database for an order fulfillment system. You create a table named Sales.Orders by using the following script:

Each order is tracked by using one of the following statuses:





You need to design the database to ensure that you can retrieve the status of an order on a given date. The solution must ensure that new statuses can be added in the future.

What should you do?

More than one answer choice may achieve the goal. Select the BEST answer.

A. Implement change data capture on the Sales.Orders table.

B. To the Sales.Orders table, add a column named Status that will store the order status. Update the Status column as the order status changes.

C. Create a new table named Sales.OrderStatus that contains three columns named OrderID, StatusDate, and Status. Insert new rows into the table as the order status changes.

D. To the Sales.Orders table, add three columns named FulfilledDate, ShippedDate, and ReceivedDate. Update the value of each column from null to the appropriate date as the order status changes.

Correct Answer: B

Question 6:

You have a database named DB1 that stores more than 700 gigabyte (GB) of data and serves millions of requests per hour.

Queries on DB1 are taking longer than normal to complete.

You run the following Transact-SQL statement:

SELECT * FROM sys.database_query_store_options

You determine that the Query Store is in Read-Only mode.

You need to maximize the time that the Query Store is in Read-Write mode.

Which Transact-SQL statement should you run?





Correct Answer: C

Stale Query Threshold (Days): Time-based cleanup policy that controls the retention period of persisted runtime statistics and inactive queries. By default, Query Store is configured to keep the data for 30 days which may be unnecessarily

long for your scenario.

Avoid keeping historical data that you do not plan to use. This will reduce changes to read- only status. The size of Query Store data as well as the time to detect and mitigate the issue will be more predictable. Use Management Studio or the

following script to configure time-based cleanup policy:




References: practice-with-the-query-store

Question 7:

You are the new database administrator for a SQL Server 2016 instance.

You conduct an assessment on the instance and determine that the auto create statistics setting on the database named DB1 has been turned off. You see no evidence that any maintenance has been occurring.

You want to set up monitoring to see if query performance is being affected.

You need to set up a monitoring process that will capture any cases where statistics could have been useful if they existed.

What should you do?

A. Create a SQL Server Agent job to execute DBCC SHOWSTATISTICS on each of the primary key columns in the database.

B. Use the missing_column_statistics extended event.

C. Query the sys.statistics system view to see all cases where the statistics were last needed.

D. Write a query using the sys.dm_db_missing_index_group_stats DMV Joining to sys.indexes, filtering on is_hypothetical.

Correct Answer: B

The Missing Column Statistics event class indicates that column statistics that could have been useful for the optimizer are not available. By monitoring the Missing Column Statistics event class, you can determine if there are statistics missing for a column used by a query. This can cause the optimizer to choose a less efficient query plan than expected.

Reference: Missing Column Statistics Event Class

Question 8:

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while

others might not have a correct solution.

After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You need to configure a Microsoft SQL Server instance to ensure that a user named Mail1 can send mail by using Database Mail.

Solution: You add the DatabaseMailUserRole to Mail1 in the tempdb database.

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: B

Database Mail is guarded by the database role DatabaseMailUserRole in the msdb database, not the tempdb database, in order to prevent anyone from sending arbitrary emails. Database users or roles must be created in the msdb database

and must also be a member of DatabaseMailUserRole in order to send emails with the exception of sysadmin who has all privileges.

Note: Database Mail was first introduced as a new feature in SQLServer 2005 and replaces the SQL Mail feature found in previous versions.

Question 9:

You create a stored procedure that retrieves all of the rows from a table named Table1.

You need to recommend a solution to ensure that all of the statements in the stored procedure can be executed if another transaction is modifying rows in Table1 simultaneously. What should you recommend?

A. Snapshot isolation

B. A database snapshot

C. Filegroups

D. Indexes

Correct Answer: A

Once snapshot isolation is enabled, updated row versions for each transaction are maintained in tempdb. A unique transaction sequence number identifies each transaction, and these unique numbers are recorded for each row version. The transaction works with the most recent row versions having a sequence number before the sequence number of the transaction. Newer row versions created after the transaction has begun are ignored by the transaction.

Reference: Transaction Isolation Levels

Question 10:

You are creating a database that will store usernames and credit card numbers for an application.

You need to recommend a solution to store and reuse the credit card numbers in the database.

What should you recommend? More than one answer choice may achieve the goal. Select the BEST answer.

A. Data encryption

B. Transparent Data Encryption (TDE)

C. Encrypting File System (EPS)

D. Data hashing

Correct Answer: B

If we are going to encrypt credit card number for storage, then we should have Data Encryption Key (DEK) for encrypting the credit card number. Reference:
