Question 1:

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

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 2:

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 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 a server that runs Microsoft SQL Server 2016 Web edition. The server has a default instance that hosts a database named DB1.

You need to ensure that you can perform auditing at the database level for DB1.

Solution: You migrate DB1 to a named instance on a server than runs Microsoft SQL Server 2016 Standard edition.

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: B

All editions of SQL Server support server level audits. All editions support database level audits beginning with SQL Server 2016 SP1. Prior to that, database level auditing was limited to Enterprise, Developer, and Evaluation editions. References: https://docs.microsoft.com/en-us/sql/relational-databases/security/auditing/sql- server-audit-database-engine


Question 4:

You deploy a database by using SQL Server 2016. The database contains a table named Table1.

You need to recommend a solution to track all of the deletions executed on Table1. The solution must minimize the amount of custom code required. What should you recommend?

A. Change data capture

B. Statistics

C. A trigger

D. Master Data Services

Correct Answer: A

Change data capture is designed to capture insert, update, and delete activity applied to SQL Server tables, and to make the details of the changes available in an easily consumed relational format. The change tables used by change data capture contain columns that mirror the column structure of a tracked source table, along with the metadata needed to understand the changes that have occurred.

Reference: About Change Data Capture (SQL Server)


Question 5:

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.

You are a database administrator for a company that has an on-premises Microsoft SQL Server environment and Microsoft Azure SQL Database instances. The environment hosts several customer databases, and each customer uses a dedicated instance. The environments that you manage are shown in the following table.

You need to monitor WingDB and gather information for troubleshooting issues. What should you use?

A. sp_updatestats

B. sp_lock

C. sys.dm_os_waiting_tasks

D. sys.dm_tran_active_snapshot_database_transactions

Correct Answer: B

The sp_lock system stored procedure is packaged with SQL Server and will give you insight into the locks that are happening on your system. This procedure returns much of its information from the syslock info in the master database, which is a system table that contains information on all granted, converting, and waiting lock requests.

Note: sp_lock will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. To obtain information about locks in the SQL Server

Database Engine, use the sys.dm_tran_locks dynamic management view.

sys.dm_tran_locks returns information about currently active lock manager resources in SQL Server 2008and later. Each row represents a currently active request to the lock manager for a lock that has been granted or is waiting to be

granted.

Question 6:

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:

Fulfilled

Shipped

Ordered

Received

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 7:

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 8:

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.

You have five servers that run Microsoft Windows 2012 R2. Each server hosts a Microsoft SQL Server instance. The topology for the environment is shown in the following diagram.

You have an Always On Availability group named AG1. The details for AG1 are shown in the following table.

Instance1 experiences heavy read-write traffic. The instance hosts a database named OperationsMain that is four terabytes (TB) in size. The database has multiple data files and filegroups. One of the filegroups is read_only and is half of the

total database size.

Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O.

Instance5 hosts a database named StagedExternal. A nightly BULK INSERT process loads data into an empty table that has a rowstore clustered index and two nonclustered rowstore indexes.

You must minimize the growth of the StagedExternal database log file during the BULK INSERT operations and perform point-in-time recovery after the BULK INSERT transaction. Changes made must not interrupt the log backup chain.

You plan to add a new instance named Instance6 to a datacenter that is geographically distant from Site1 and Site2. You must minimize latency between the nodes in AG1.

All databases use the full recovery model. All backups are written to the network location \\SQLBackup\. A separate process copies backups to an offsite location. You should minimize both the time required to restore the databases and the space required to store backups. The recovery point objective (RPO) for each instance is shown in the following table.

Full backups of OperationsMain take longer than six hours to complete. All SQL Server backups use the keyword COMPRESSION. You plan to deploy the following solutions to the environment. The solutions will access a database named DB1 that is part of AG1. The wait statistics monitoring requirements for the instances are described in the following table.

You need to create a backup plan for Instance4. Which backup plan should you create?

A. Weekly full backups, nightly differential. No transaction log backups are necessary.

B. Weekly full backups, nightly differential backups, transaction log backups every 5 minutes.

C. Weekly full backups, nightly differential backups, transaction log backups every 12 hours.

D. Weekly full backups, nightly differential backups, nightly transaction log backups.

Correct Answer: B

From scenario: Instance4 and Instance5 are not part of AG1. Instance4 is engaged in heavy read-write I/O. The recovery point objective of Instancse4 is 60 minutes. RecoveryPoint Objectives are commonly described as the amount of data that was lost during the outage and recovery period.

References:http://sqlmag.com/blog/sql-server-recovery-time-objectives-and-recovery-point- objectives


Question 9:

You manage a SQL Server 2016 instance that contains a database named DB1. Users report that some queries to DB1 take longer than expected. Although most queries run in less than one second, some queries take up to 20 seconds to

run.

You need to view all of the performance statistics for each database file.

Which method should you use?

A. Query the sys.dm_os_tasks dynamic management view.

B. Query the sys.dm_os_performance_counters dynamic management view.

C. Query the sys.dm_io_virtual_file_stats dynamic management function.

D. Examine the Data File I/O pane in Activity Monitor.

Correct Answer: C

sys.dm_io_virtual_file_stats

Returns I/O statistics for data and log files.

Reference: sys.dm_io_virtual_file_stats (Transact-SQL)


Question 10:

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.
