Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 2 - 070-458무료 덤프문제 풀어보기
HOTSPOT
You are developing a SQL Server Integration Services (SSIS) package. An Execute SQL task in the package checks product stock levels and sets a package variable named InStock to TRUE or FALSE depending on the stock level found.
After the successful execution of the Execute SQL task, one of two data flow tasks must run, depending on the value of the InStock variable.
You need to set the precedence constraints.
Which value for the evaluation operation should you use? (To answer, select the appropriate option for the evaluation operation in the answer area.)

You are developing a SQL Server Integration Services (SSIS) package. The data source for the data flow task is a table that has been configured as a change data capture (CDC) table. You are using a CDC Source component to obtain the CDC data.
The data source will be polled once per hour. The data is updated with multiple important status changes per minute.
For each captured data change, the before and after values must be included.You need to configure the CDC Source component.
Which CDC processing mode should you select? (To answer, configure the appropriate option in the dialog box in the answer area.)

You are developing a SQL Server Integration Services (SSIS) package.
The package control flow will contain many tasks. The tasks will execute consecutively and none will execute more than once. Certaingroups of tasks will share variable and transaction scope.
You need to group tasks together while enabling them to be collapsed and expanded as a group.
Which item should you use from the SSIS Toolbox? (To answer, select the appropriate item in the answer area.)

You administer a Microsoft SQL Server 2012 database that has Trustworthy set to on. You create a stored procedure that returns database-level information from Dynamic Management Views.
You grant User1 access to execute the stored procedure.
You need to ensure that the stored procedure returns the required information when User1 executes the stored procedure. You need to achieve this goal by granting the minimum permissions required.
What should you do? Choose all that apply.

You are designing a package control flow. The package moves sales order data from a Windows Azure SQL Database transactional database to an on-premise reporting database. The package will run several times a day, while new sales orders are being added to the transactional database.
The current design of the package control flow is shown in the answer area. (Click the Exhibit button.)
---
The Insert New Orders Data Flow task must meet the following requirements:
Usage of the tempdb database should not be impacted.
Concurrency should be maximized, while only reading committed transactions.
If the task fails, only that task needs to be rolled back.
You need to configure the Insert New Orders Data Flow task to meet the requirements.
How should you configure the transaction properties? To answer, select the appropriate setting or settings in the answer area.

You are developing a SQL Server Integration Services (SSIS) package that downloads data from a Windows Azure SQL Database database.
A stored procedure will be called in an Execute SQL task by using an ODBC connection. This stored procedure has only the rustomerlD parameter of type INT.
A project parameter named CustID will be mapped to the stored procedure parameter @CustomerID.
You need to ensure that the value of the CustID parameter is passed to the @CustomerID stored procedure parameter.
In the Parameter Mapping tab of the Execute SQL task editor, how should you configure the parameter? (To answer, drag the appropriate option or options to the correct location or locations in the answer area.)

You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has S GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.
----
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
On Wednesday at 10:00 hours, the development team requests you to refresh the database on a development server by using the most recent version.
You need to perform a full database backup that will be restored on the development server.
Which backup option should you use?

A SQL Server Integration Services (SSIS) 2012 package currently downloads sales data from a Windows Azure SQL Database database.
To improve sales data accuracy, exchange rates must be downloaded daily from a public HTTP web service instead of from a weekly flat file.
You need to implement the change to the existing package while minimizing the development effort.
What should you use to call the web service to retrieve the daily exchange rates?

A SQL Server Integration Services (SSIS) package imports daily transactions from several files into a SQL Server table named Transaction. Each file corresponds to a different store and is imported in parallel with the other files. The data flow tasks use OLE DB destinations in fast load data access mode.
The number of daily transactions per store can be very large and is growing. The Transaction table does not have any indexes.
You need to minimize the package execution time.
