New Question
You deploy a database by using SQL Server 2014.
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
Answer: A
Explanation:
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.
New Question
You have four databases that are accessed by using an Online Transaction Processing (OLTP) application.
The databases are stored on a server named SQL1 that has SQL Server 2014 installed.
You plan to deploy an additional server that has SQL Server 2014 installed.
You need to design a high-availability solution for the databases that meets the following requirements:
– If SQL1 fails, the databases must be available.
– Users must be able to run reports against a secondary copy of the databases.
What should you include in the design? More than one answer choice may achieve the goal. Select the BEST answer.
A. AlwaysOn availability groups
B. Database mirroring
C. Log shipping
D. Failover Clustering
Answer: A
Explanation:
The AlwaysOn Availability Groups feature is a high-availability and disaster-recovery solution that provides an enterprise-level alternative to database mirroring. Introduced in SQL Server 2012, AlwaysOn Availability Groups maximizes the availability of a set of user databases for an enterprise. An availability group supports a failover environment for a discrete set of user databases, known as availability databases, that fail over together.
New Question
You are troubleshooting an application that runs a query.
The application frequently causes deadlocks.
You need to identify which transaction causes the deadlock.
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. Create an extended events session to capture deadlock information.
Answer: D
Explanation:
Troubleshooting deadlocks
You have been receiving reports from users indicating that certain applications are returning deadlock errors. To maximize the effectiveness of troubleshooting these problems, you decide to focus on the deadlocks that are hit most frequently.
You create an Extended Events session that:
– Configures deadlock event tracking for the session.
– Specifies a target that aggregates based on an identifier for the deadlock.
You run the Extended Events session, and after additional deadlocks are reported you are able to obtain aggregated deadlock information, along with the complete XML deadlock graph for each source. Using this information you are able to pin point the most common deadlocks and start working on a solution.
New Question
Drag and Drop Question
You have a server named SQL1 that has SQL Server 2012 installed.
SQL1 hosts a database named Database1.
Database1 contains a table named Table1.
Table1 is partitioned across five filegroups based on the Date field.
The schema of Table1 is configured as shown in the following table.
Table1 contains the indexes shown in the following table.
You need to recommend an index strategy to maximize performance for the queries that consume the indexes available to Table1.
Which type of index storage should you recommend? To answer, drag the appropriate index storage type to the correct index in the answer area.
Answer:
Explanation:
Index Storage Type
– Designing a partitioned index independently (unaligned) of the base table can be useful in the following cases:
– The base table has not been partitioned.
– The index key is unique and it does not contain the partitioning column of the table.
– You want the base table to participate in collocated joins with more tables using different join columns.
New Question
Drag and Drop Question
You plan to deploy SQL Server 2014.
Your company identifies the following monitoring requirements:
– Tempdb must be monitored for insufficient free space.
– Deadlocks must be analyzed by using Deadlock graphs.
You need to identify which feature meets each monitoring requirement.
Which features should you identify? To answer, drag the appropriate feature to the correct monitoring requirement in the answer area.
Answer:
Explanation:
– You can use the sys.dm_db_file_space_usage dynamic management view to monitor the disk space used by the user objects, internal objects, and version stores in the tempdb files. Additionally, to monitor the page allocation or deallocation activity in tempdb at the session or task level, you can use the sys.dm_db_session_space_usage and sys.dm_db_task_space_usage dynamic management views.
These views can be used to identify large queries, temporary tables, or table variables that are using a large amount of tempdb disk space.
– Use SQL Server Profiler to identify the cause of a deadlock. A deadlock occurs when there is a cyclic dependency between two or more threads, or processes, for some set of resources within SQL Server. Using SQL Server Profiler, you can create a trace that records, replays, and displays deadlock events for analysis.
– SQL Server Profiler and SQL Server Management Studio use a deadlock wait-for graph to describe a deadlock. The deadlock wait-for graph contains process nodes, resource nodes, and edges representing the relationships between the processes and the resources.

New Question
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 2014 Enterprise
B. SQL Server 2014 Standard
C. SQL Azure
D. SQL Server 2014 Express with Advanced Services
Answer: B
Explanation:
Programmability (AMO, ADOMD.Net, OLEDB, XML/A, ASSL) supported by Standard and Enterpirse editions only.
Reference: Features Supported by the Editions of SQL Server 2014
New Question
You are designing a database named DB1.
Changes will be deployed to DB1 every Wednesday night.
You need to recommend a strategy to deploy the changes to DB1.
The strategy must meet the following requirements:
– The strategy must not disrupt backup operations.
– DB1 must be unavailable to users while the changes are deployed.
– You must be able to undo quickly the entire operation.
What should you recommend? More than one answer choice may achieve the goal. Select the BEST answer.
A. Perform a copy-only database backup before the changes are deployed.
If the deployment fails, restore the database to another server and recover the original
Objects from the restored database.
B. Create a database snapshot.
If the deployment fails, recover the objects from the database snapshot.
C. Create a database snapshot.
If the deployment fails, revert the database to the database snapshot.
D. Perform a full database backup before the changes are deployed.
If the deployment fails, restore the database to another server and recover the original
objects from the restored database.
Answer: C
New Question
Drag and Drop Question
You plan to deploy SQL Server 2014.
You are designing two stored procedures named SP1 and SP2 that have the following requirements:
– Prevent data read by SP1 from being modified by other active processes.
– Prevent SP2 from performing dirty reads.
You need to recommend the isolation level for each stored procedure.
The solution must maximize concurrency.
Which isolation levels should you recommend? To answer, drag the appropriate isolation level to the correct stored procedure in the answer area.
Answer:
Explanation:
– REPEATABLE READ
This isolation level includes the guarantees given by SNAPSHOT isolation level.
In addition, REPEATABLE READ guarantees that for any row that is read by the transaction, at the time the transaction commits the row has not been changed by any other transaction.
Every read operation in the transaction is repeatable up to the end of the transaction.
– Committed Read is SQL Server’s default isolation level. It ensures that an operation will never read data another application has changed but not yet committed.
New Question
Drag and Drop Question
You are designing an authentication strategy for a new server that has SQL Server 2014 installed.
The strategy must meet the following business requirements:
– The account used to generate reports must be allowed to make a connection during certain hours only.
– Failed authentication requests must be logged.
You need to recommend a technology that meets each business requirement.
The solution must minimize the amount of events that are logged.
Which technologies should you recommend? To answer, drag the appropriate solution to the correct business requirement in the answer area.
Answer:
Explanation:
– Logon triggers fire stored procedures in response to a LOGON event.
This event is raised when a user session is established with an instance of SQL Server.
Logon triggers fire after the authentication phase of logging in finishes, but before the user session is actually established.
You can use logon triggers to audit and control server sessions, such as by tracking login activity, restricting logins to SQL Server, or limiting the number of sessions for a specific login.
– Login auditing can be configured to write to the error log on the following events.
– Failed logins
– Successful logins
– Both failed and successful logins
Incorrect:
– C2 audit mode can be configured through SQL Server Management Studio or with the c2 audit mode option in sp_configure. Selecting this option will configure the server to record both failed and successful attempts to access statements and objects.
New Question
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. 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.
B. 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.
C. Implement change data capture on the Sales.Orders table.
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.
Answer: B
New Question
You have two SQL Server 2012 instances named SQLDev and SQLProd.
You plan to create a new database on SQLProd that will use SQL Server Authentication.
You need to ensure that when the new database is copied from SQLProd to SQLDev, users can connect to the database on SQLDev if they do not have a login on the SQLDev instance.
What should you use? More than one answer choice may achieve the goal. Select the BEST answer.
A. SQL Server Integration Services (SSIS) scripts
B. Extended Events
C. Triggers
D. SQL Server Analysis Services (SSAS) scripts
E. Contained database
Answer: E
Explanation:
A fully contained database includes all the settings and metadata required to define the database and has no configuration dependencies on the instance of the SQL Server Database Engine where the database is installed.
