Q61. You are creating a sales data warehouse. When a product exists in the product dimension, you update the product name. When a product does not exist, you insert a new record.
In the current implementation, the DimProduct table must be scanned twice, once for the insert and again for the update. As a result, inserts and updates to the DimProduct table take longer than expected.
You need to create a solution that uses a single command to perform an update and an insert.
How should you use a MERGE T-SQL statement to accomplish this goal? (To answer, drag the appropriate answer choice from the list of options to the correct location or locations in the answer area.
You may need to drag the split bar between panes or scroll to view content.)
Answer:
Q62. You are designing an enterprise star schema that will consolidate data from three independent data marts. One of the data marts is hosted on SQL Azure.
Most of the dimensions have the same structure and content. However, the geography dimension is slightly different in each data mart.
You need to design a consolidated dimensional structure that will be easy to maintain while ensuring that all dimensional data from the three original solutions is represented.
What should you do?
A. Create a conformed dimension for the geography dimension.
B. Implement change tracking.
C. Create a degenerate dimension for the geography dimension.
D. Create a Type 2 slowly changing dimension for the geography dimension.
Answer: A
Q63. You are completing the installation of the Data Quality Server component of SQL Server Data Quality Services (DQS).
You need to complete the post-installation configuration.
What should you do?
A. Run the DQSInstaller.exe command.
B. Install the data providers that are used for data refresh.
C. Install ADOMD.NET.
D. Run the dbimpexp.exe command.
Answer: A

Q64. You are the Master Data Services (MDS) administrator at your company.
An existing user must be denied access to a certain hierarchy node for an existing model.
You need to configure the user's permissions.
Which user management menu item should you select? (To answer, configure the
appropriate option or options in the dialog box in the answer area.)
Answer:
Q65. You are editing a SQL Server Integration Services (SSIS) package that contains three Execute SQL tasks and no other tasks. The package and all three Execute SQL tasks have their TransactionOption property set to Supported.
You need to ensure that if any of the Execute SQL tasks fail, all three tasks will roll back their changes.
What should you do?
A. Move the three Execute SQL tasks into a Sequence container.
B. Move the three Execute SQL tasks into a Foreach Loop container.
C. Change the TransactionOption property of all three Execute SQL tasks to Required.
D. Change the TransactionOption property of the package to Required.
Answer: D

Q66. To support the implementation of new reports, Active Directory data will be downloaded to a SQL Server database by using a SQL Server Integration Services (SSIS) 2012 package.
The following requirements must be met:
All the user information for a given Active Directory group must be downloaded to a SQL Server table. The download process must traverse the Active Directory hierarchy recursively.
You need to configure the package to meet the requirements by using the least development effort.
What should you use?
A. script component
B. custom component
C. XML source
D. script task
Answer: A
Q67. 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.
What should you do?
A. Partition the table by day and store.
B. Create a clustered index on the Transaction table.
C. Run the package in Performance mode.
D. Increase the value of the Row per Batch property.
Answer: D
Explanation: * Data Access Mode – This setting provides the 'fast load' option which internally uses a BULK INSERT statement for uploading data into the destination table instead of a simple INSERT statement (for each single row) as in the case for other options.
* BULK INSERT parameters include: ROWS_PER_BATCH =rows_per_batch Indicates the approximate number of rows of data in the data file. By default, all the data in the data file is sent to the server as a single transaction, and the number of rows in the batch is unknown to the query optimizer. If you specify ROWS_PER_BATCH (with a value > 0) the server uses this value to optimize the bulk-import operation. The value specified for ROWS_PER_BATCH should approximately the same as the actual number of rows.
Q68. You are designing a package control flow. The package moves sales order data from a SQL Azure 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.
Select “IsolationLeve as Choas”
Answer:
Q69. A new dedicated server is used to execute resource-intensive SQL Server Integration Services (SSIS) 2012 packages. The environment that you are deploying the packages to has the following constraints:
The operating system is Windows Server 2008 R2. The SSIS packages are stored in the SSIS catalog. Some of these SSIS packages use 32-bit custom components.
You need to install only the components that are required to deploy and run the packages on the new server.
Which three actions should you perform in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
Answer:
Q70. You are implementing a SQL Server Integration Services (SSIS) package that loads data hosted in a SQL Azure database into a data warehouse.
The source system contains redundant or inconsistent data. When the package finds invalid data, the row containing the invalid data must be omitted but it must also be written to a text file for further analysis.
You need to establish the best technique to log these invalid rows while keeping the amount of development effort to a minimum.
What should you do?
A. Add an OnError event handler to the SSIS project.
B. Open a command prompt and execute the package by using the SQL Log provider and running the dtexecui.exe utility.
C. Use an msi file to deploy the package on the server.
D. Open a command prompt and run the gacutil command.
E. Run the dtutil command to deploy the package to the SSIS catalog and store the configuration in SQL Server.
F. Open a command prompt and run the dtutil /copy command.
G. Create a reusable custom logging component and use it in the SSIS project.
H. Configure the SSIS solution to use the Project Deployment Model.
I. Configure the output of a component in the package data flow to use a data tap.
J. Open a command prompt and run the dtexec /rep /conn command.
K. Open a command prompt and run the dtexec /dumperror /conn command.
