Question 1:

You plan to create a database.

The database will be used by a Microsoft .NET application for a special event that will last for two days.

During the event, data must be highly available.

After the event, the database will be deleted.

You need to recommend a solution to implement the database while minimizing costs. The solution must not affect any existing applications.

What should you recommend?

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

A. SQL Server 2016 Enterprise

B. SQL Server 2016 Standard

C. SQL Azure

D. SQL Server 2016 Express with Advanced Services

Correct Answer: B

Programmability (AMO, ADOMD.Net, OLEDB, XML/A, ASSL) supported by Standard and Enterprise editions only. Reference: Features Supported by the Editions of SQL Server 2016

Question 2:

You are designing a monitoring application for a new SQL Server 2016 instance.

You need to recommend a solution to generate a report that displays the 10 most frequent wait types that occur for the instance.

What should you include in the recommendation?

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

A. The SQL Server error log

B. The sys.dm_os_wait_stats dynamic management view

C. The DBCC SQLPERF(WAITSTATS) command

D. SQL Server Profiler

Correct Answer: B

sys.dm_os_wait_stats

Returns information about all the waits encountered by threads that executed. You can use this aggregated view to diagnose performance issues with SQL Server and also with specific queries and batches.

Columns include:

waiting_tasks_count

Number of waits on this wait type. This counter is incremented at the start of each wait.

Reference:

sys.dm_db_wait_stats (Windows Azure SQL Database)

Question 3:

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.

A company has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environment hosts several customer databases.

One customer reports that their database is not responding as quickly as the service level agreements dictate. You observe that the database is fragmented.

You need to optimize query performance.

Solution: You rebuild all indexes.

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: A

You can remedy index fragmentation by either reorganizing an index or by rebuilding an index. References:https://msdn.microsoft.com/en-us/library/ms189858(v=sql.105).aspx

Question 4:

You have a server named Server1 that has 16 processors.

You plan to deploy multiple instances of SQL Server 2016 to Server1. You need to recommend a method to allocate processors to each instance.

What should you include in the recommendation?

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

A. Processor affinity

B. Windows System Resource Manager (WSRM)

C. Max Degree of Parallelism

D. Resource Governor

Correct Answer: A

CPU affinity management through Windows System Resource Manager is not recommended for SQL Server multi-instance management. Instead, use the processor affinity settings in SQL Server. Reference: Server Properties (Processors Page)

Question 5:

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.

Question 7:

You have a query that is used by a reporting dashboard.

Users report that the query sometimes takes a long time to run.

You need to recommend a solution to identify what is causing the issue.

What should you recommend?

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

A. Set the blocked process threshold, and then run SQL Server Profiler.

B. Set the blocked process threshold, and then create an alert.

C. Enable trace flag 1204, and then create an alert.

D. Create a job that queries the sys.dm_os_waiting_tasks dynamic management view.

Correct Answer: B

Step 1: Turn on the blocked process report. This will look for any blocking taking 20 seconds or longer.

–Make sure you don\’t have any pending changes SELECT * FROM sys.configurations WHERE value value_in_use; GO

exec sp_configure \’show advanced options\’, 1; GO RECONFIGURE GO

exec sp_configure \’blocked process threshold (s)\’, 20; GO RECONFIGURE GO Step 2: Set up a trace to capture the blocked process report. Run it as a server side trace.

Reference: blocked process threshold Server Configuration Option

Question 8:

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 have an on-premises server that runs Microsoft SQL Server 2016 Standard Edition.

You need to identify missing indexes.

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: D

Data Collector can gather performance information from multiple SQL Server instances and store it in a single repository. It has three built-in data collecting specifications (data collectors) designed to collect the most important performance metrics. The information collected by default is about disk usage, query statistics, and server activity. The Query Statistics data collection set collects information about query statistics, activity, execution plans and text on the SQL Server instance. Missing indexes can be found with the execution plans.

References: https://www.sqlshack.com/sql-server-performance-monitoring-data-collector/

Question 9:

You are building a stored procedure for a Windows Azure SQL Database. The procedure will add multiple rows to a table.

You need to design the stored procedure to meet the following requirements:

If any of the new rows violates a table constraint, then no further additions must be attempted and all changes made by the stored procedure must be discarded.

If any errors occur, a row must be added to an audit table, and the original error must be returned to the caller of the stored procedure.

What should you include in the design?

A. An explicit transaction that has XACT_ABORT disabled

B. An implicit transaction that has error handling enabled

C. An explicit transaction that has error handling enabled

D. An implicit transaction that has XACT.ABORT enabled

Correct Answer: C

Reference: http://technet.microsoft.com/en-us/library/ms175127(v=SQL.105).aspx

Question 10:

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

A company has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environment hosts a customer database named DB1.

Customers connect to hosted database instances by using line-of-business applications. Developers connect by using SQL Server Management Studio (SSMS).

You need to grant the developers permission to alter views for DB1 while following the principle of least privilege.

Which permission should you grant?

A. DDLAdmin

B. db_datawriter

C. dbcreator

D. dbo

E. View Database State

F. View Server State

G. View Definition

H. sysadmin

Correct Answer: A

To execute ALTER VIEW, at a minimum, ALTER permission on OBJECT is required. Members of the db_ddladmin fixed database role can run any Data Definition Language (DDL) command in a database. References: https://technet.microsoft.com/en-us/library/ms190667(v=sql.90).aspx
