CREATE PARTITION FUNCTION TransactionRangePF1 (DATETIME) AS RANGE RIGHT FOR VALUES

(

#39;20071001#39;, #39;20071101#39;, #39;20071201#39;, #39;20080101#39;,

); GO

CREATE TABLE dbo.TransactionHistory (

TransactionID INT NOT NULL, – not bothering with IDENTITY here ProductID INT NOT NULL,

ReferenceOrderID INT NOT NULL, ReferenceOrderLineID INT NOT NULL DEFAULT (0),

Question No: 133 – (Topic 12)

You have two databases named DB1 and DB2 that are located on the same server. You plan to create a stored procedure named SProc1 in DB1.

SProc1 will query a table named Table2 in DB2.

You need to recommend a solution to ensure that SProc1 can access Table2 without granting users direct access to Table2.

What should you include in the recommendation?

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

  1. Contained databases

  2. Application roles

  3. Cross-database ownership chaining

  4. Digital certificates

Answer: B

Explanation: An application role is a database principal that enables an application to run with its own, user-like permissions. You can use application roles to enable access to specific data to only those users who connect through a particular application. Unlike database roles, application roles contain no members and are inactive by default.

Application Roles

Question No: 134 – (Topic 12)

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.

  1. AlwaysOn availability groups

  2. Database mirroring

  3. Log shipping

  4. 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.

Failover and Failover Modes (AlwaysOn Availability Groups)

Question No: 135 – (Topic 12)

You are designing a Windows Azure SQL Database for an order fulfillment system. You create a table named Sales.Orders with the following script.

Ensurepass 2018 PDF and VCE

Each order is tracked by using one of the following statuses:

->Fulfilled

->Shipped

->Ordered

->Received

You need to design the database to ensure that that you can retrieve the following information:

->The current status of an order

->The previous status of an order.

->The date when the status changed.

The solution must minimize storage.

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

  1. To the Sales.Orders table, add three columns named Status, PreviousStatus and ChangeDate. Update rows as the order status changes.

  2. 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.

  3. Implement change data capture on the Sales.Orders table.

  4. 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

Question No: 136 – (Topic 12)

You manage a SQL Server 2014 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?

  1. Query the sys.dm_os_tasks dynamic management view.

  2. Query the sys.dm_os_performance_counters dynamic management view.

  3. Query the sys.dm_io_virtual_file_stats dynamic management function.

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

Answer: C

Explanation: sys.dm_io_virtual_file_stats Returns I/O statistics for data and log files. sys.dm_io_virtual_file_stats (Transact-SQL)

Question No: 137 – (Topic 12)

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 online while the changes are deployed.

->You must be able to undo quickly any changes made to objects.

What should you recommend?

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

  1. 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.

  2. Create a database snapshot. If the deployment fails, recover the objects from the database snapshot.

  3. Create a database snapshot. If the deployment fails, revert the database to the

    database snapshot.

  4. 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

Explanation: Database Snapshots (SQL Server)

Question No: 138 DRAG DROP – (Topic 12)

You need to recommend a backup process for data warehouse database.

The solution must meet the following requirements:

->Ensure that if a hardware failure occurs, you can bring the database online without losing more than 24 hours of transactions.

->Minimize the amount of administrative effort required to restore any lost data.

->Minimize the space used by transaction logs.

What should you include in the recommendation?

To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Ensurepass 2018 PDF and VCE

Answer:

Ensurepass 2018 PDF and VCE

Explanation:

Box 1: Set the database to the simple recovery model. Box 2: Perform a weekly full backup of the database.

Box 3: Perform a differential backup of the database every night.

Note:

  • Simple recovery model No log backups.

  • Full recovery model Requires log backups

Question No: 139 DRAG DROP – (Topic 12)

You use SQL Server 2014.

You need to create a single object that inserts a provided value into Table1, and then returns a count of the records in Table1.

Develop the solution by selecting and arranging the required code blocks in the correct order. You may not need all of the code blocks.

Question No: 140 – (Topic 12)

You have a SQL Server 2014 database named DB1.

You plan to import a large number of records from a SQL Azure database to DB1.

You need to recommend a solution to minimize the amount of space used in the transaction log during the import operation.

What should you include in the recommendation?

  1. The bulk-logged recovery model

  2. The full recovery model

  3. A new partitioned table

  4. A new log file

  5. A new file group

Answer: A

Explanation: Compared to the full recovery model, which fully logs all transactions, the bulk-logged recovery model minimally logs bulk operations, although fully logging other transactions. The bulk-logged recovery model protects against media failure and, for bulk operations, provides the best performance and least log space usage.

Note:

The bulk-logged recovery model is a special-purpose recovery model that should be used only intermittently to improve the performance of certain large-scale bulk operations, such as bulk imports of large amounts of data.
