Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You deploy Microsoft SQL Server to a virtual machine in Azure. You distribute the database files and filegroups across multiple Azure storage disks. 
You must be able to manage the databases as individual entities by using SQL Server Management Studio. All data in the databases must be stored encrypted. Backups must be encrypted by using the same key as the live copy of the database. 
You need to secure the data. 
What should you implement?
  1. transport-level encryption
  2. cell-level encryption
  3. Transparent Data Encryption
  4. Always Encrypted
  5. Encrypting File System
  6. BitLocker
  7. dynamic data masking
Correct answer: C
Explanation:
Transparent data encryption (TDE) encrypts your databases, associated backups, and transaction log files at rest without requiring changes to your applications. TDE encrypts the storage of an entire database by using a symmetric key called the database encryption key. In SQL Database the database encryption key is protected by a built-in server certificate. The built-in server certificate is unique for each SQL Database server. References: https://msdn.microsoft.com/en-us/library/dn948096.aspx

Question 3
You are deploying a Microsoft SQL Server database that will support a mixed OLTP and OLAP workload. The target virtual machine has four CPUs. 
You need to ensure that reports do not use all available system resources. 
What should you do?
  1. Increase the default database file auto growth sizes.
  2. Increase the value for the Minimum System Memory setting.
  3. Set MAXDOP to half the number of CPUs available.
  4. Increase the value for the Minimum Memory per query setting.
Correct answer: C
Explanation:
When an instance of SQL Server runs on a computer that has more than one microprocessor or CPU, it detects the best degree of parallelism, that is, the number of processors employed to run a single statement, for each parallel plan execution. You can use the max degree of parallelism option to limit the number of processors to use in parallel plan execution. Incorrect Answers:A: The Auto Close property exposes server behavior for databases not accessed by a user. This feature 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.References: https://msdn.microsoft.com/en-us/library/ms189094.aspx

Question 4
A company has an on-premises Microsoft SQL Server 2014 environment. The company has a main office in Seattle, and remote offices in Amsterdam and Tokyo. You plan to deploy a Microsoft Azure SQL Database instance to support a new application. You expect to have 100 users from each office. 
In the past, users at remote sites reported issues when they used applications hosted at the Seattle office. 
You need to optimize performance for users running reports while minimizing costs. 
What should you do?
  1. Implement an elastic pool.
  2. Implement a standard database with readable secondaries in Asia and Europe, and then migrate the application.
  3. Implement replication from an on-premises SQL Server database to the Azure SQL Database instance.
  4. Deploy a database from the Premium service tier.

Question 5
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets stated goals.
You have a mission-critical application that stores data in a Microsoft SQL Server instance. The application runs several financial reports. The reports use a SQL Server-authenticated login named Reporting_User. All queries that write data to the database use Windows authentication. 
Users report that the queries used to provide data for the financial reports take a long time to complete. The queries consume the majority of CPU and memory resources on the database server. As a result, read-write queries for the application also take a long time to complete. 
You need to improve performance of the application while still allowing the report queries to finish. 
Solution: You create a snapshot of the database. You configure all report queries to use the database snapshot.
Does the solution meet the goal?
  1. Yes
  2. No
Correct answer: B
Explanation:
Use a Resource Governor instead. References: https://msdn.microsoft.com/en-us/library/bb933866.aspx

You need to improve performance of the application while still allowing the report queries to finish. 
Solution: You configure the Resource Governor to limit the amount of memory, CPU, and IOPS used for the pool of all queries that the Reporting_user login can run concurrently.
Does the solution meet the goal?
  1. Yes
  2. No
Correct answer: A
Explanation:
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. References: https://msdn.microsoft.com/en-us/library/bb933866.aspx

Solution: You configure the Resource Governor to set the MAXDOP parameter to 0 for all queries against the database.
Does the solution meet the goal?
  1. Yes
  2. No
Correct answer: B
Explanation:
SQL Server will consider parallel execution plans for queries, index data definition language (DDL) operations, and static and keyset-driven cursor population. You can override the max degree of parallelism value in queries by specifying the MAXDOP query hint in the query statement. References: https://technet.microsoft.com/en-us/library/ms181007(v=sql.105).aspx

Question 8
You administer a Microsoft SQL Server 2012 database. 
Users report that an application that accesses the database displays an error, but the error does not provide meaningful information. No entries are found in the SQL Server log or Windows event logs related to the error. 
You need to identify the root cause of the issue by retrieving the error message. 
What should you do?
  1. Create an Extended Events session by using the sqlserver.error_reported event.
  2. Create a SQL Profiler session to capture all ErrorLog and EventLog events.
  3. Flag all stored procedures for recompilation by using sp_recompile.
  4. Execute sp_who.
Correct answer: A
Explanation:
Event sqlserver.error_reported: This event gets fired every time that an error happens in the server.References: https://blogs.msdn.microsoft.com/extended_events/2010/04/14/introduction-to-extended-events/

Question 9
You administer a Microsoft SQL Server 2012 server. One of the databases on the server supports a highly active OLTP application. 
Users report abnormally long wait times when they submit data into the application. 
You need to identify which queries are taking longer than 1 second to run over an extended period of time. 
What should you do?
  1. use SQL Profiler to trace all queries that are processing on the server. Filter queries that have a Duration value of more than 1,000.
  2. Use sp_configure to set a value for blocked process threshold. Create an extended event session.
  3. Use the Job Activity monitor to review all processes that are actively running. Review the Job History to find out the duration of each step.
  4. Run the sp_who command from a query window.
  5. Run the DBCC TRACEON 1222 command from a query window and review the SQL Server event log.
Correct answer: A
Explanation:
Incorrect Answers:E: DBCC TRACEON 1222 is used to detect deadlocks, not to detect long running queries.References:http://www.mssqltips.com/sqlservertip/2130/finding-sql-server-deadlocks-using-trace-flag-1222/ http://msdn.microsoft.com/en-us/library/ms188396.aspx

Question 10
You administer a Microsoft SQL Server 2012 database. 
You need to ensure that the size of the transaction log file does not exceed 2 GB. 
What should you do?
  1. Execute sp_configure 'max log size', 2G.
  2. use the ALTER DATABASE...SET LOGFILE command along with the maxsize parameter.
  3. In SQL Server Management Studio, right-click the instance and select Database Settings. Set the maximum size of the file for the transaction log.
  4. in SQL Server Management Studio, right-click the database, select Properties, and then click Files. Open the Transaction log Autogrowth window and set the maximum size of the file.
Correct answer: B
Explanation:
You can use the ALTER DATABASE (Transact-SQL) statement to manage the growth of a transaction log file To control the maximum the size of a log file in KB, MB, GB, and TB units or to set growth to UNLIMITED, use the MAXSIZE option. However, there is no SET LOGFILE subcommand. References: https://technet.microsoft.com/en-us/library/ms365418(v=sql.110).aspx#ControlGrowth
