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 have a server named Server1 that has 2 processors.

You plan to deploy multiple instances of SQL Server 2016 to Server1. Each instance will have multiple databases.

You need to recommend a method to allocate processor time to each database.

What should you include in the recommendation?

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

A. Resource Governor

B. Max Degree of Parallelism

C. Windows System Resource Manager (WSRM)

D. Processor affinity

Correct Answer: A

SQL Server Resource Governor is a feature than you can use to manage SQL Server workload and system resource consumption. Resource Governor enables you to specify limits on the amount of CPU, physical IO, and memory that

incoming application requests can use.

Reference: Resource Governor

Incorrect:

D: PROCESS AFFINITY

Enables hardware threads to be associated with CPUs.

Question 3:

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 4:

You are the administrator for a SQL Server 2016 instance that stores the data for an online transaction processing sales system.

The company takes full backups every week; differential backups on the days with no full backups; and hourly transaction backups. These backups are stored on a backup server in the company\’s data center.

Every week, the company places the full backup on a tape and sends it to a third-party backup storage system.

The company is worried that a disaster might occur that could destroy their computer center and cause them to lose orders.

You need to determine the best method for providing the smallest amount of data loss and downtime without leasing or purchasing additional physical locations.

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

A. Set up SQL Server Always On with a SQL Azure database as a replica.

B. Set up SQL Server Always On by using a SQL Server on a Windows Azure Virtual Machine.

C. Put the differential backup on tape and send it to the third-party backup storage system.

D. Use the Microsoft SQL Server Backup to Microsoft Windows Azure Tool to direct all backups to a different geographical location.

Correct Answer: D

SQL Server 2012 was the first version to provide the ability to back up databases to the Cloud, and SQL Server 2016 improves on the process.

Microsoft SQL Server Backup to Windows Azure Tool enables backup to Windows Azure Blob Storage and encrypts and compresses SQL Server backups stored locally or in the cloud.

A. Processor affinity

B. Windows System Resource Manager (WSRM)

C. Max Degree of Parallelism

D. Resource Governor

Question 6:

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 7:

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: http://msdn.microsoft.com/en-us/library/bb934049.aspx

Question 8:

You have a SQL Server 2016 environment that includes four servers. The servers are configured as shown in the following table.

You plan to configure Policy-Based Management to enforce the following rules:

On Server1, enable SQL Server password policies and enable the default trace. On Server3, ensure that the names of user-defined stored procedures begin with the prefix “usp_” and ensure that all databases use a case-sensitive collation.

You need to recommend which server you must configure as a Central Management Server.

Which server should you recommend? (Each correct answer presents a complete solution.

Choose all that apply.)

A. Server1

B. Server2

C. Server3

D. Seiver4

Correct Answer: AC

Question 9:

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 10:

You are troubleshooting an application that runs a query. The application frequently causes deadlocks.

You need to identify the isolation level used by the query when a deadlock occurs.

What should you do?

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

A. Query the sys.dm_exec_requests dynamic management view.

B. Create a trace in SQL Server Profiler that contains the Deadlock graph event.

C. Query the sys.dm_exec_sessions dynamic management view.

D. Enable trace flag 1222, and then view the SQL Server error log.

Correct Answer: C

* sys.dm_exec_sessions Returns one row per authenticated session on SQL Server. sys.dm_exec_sessions is a server-scope view that shows information about all active user connections and internal tasks. Include the column: transaction_isolation_level smallint Transaction isolation level of the session. 0 = Unspecified 1 = ReadUncomitted 2 = ReadCommitted 3 = Repeatable 4 = Serializable 5 = Snapshot Is not nullable.
