QUESTION NO: 1
You are the administrator of a server that hosts Data Quality Server for a large retail company.
The server had a hardware failure during business hours.
You need to restore the server that hosts Data Quality Server to another server. You have a recent backup of all the required databases.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
A. Restore the DQS_MAIN, DQS_PROJECTS, and DQS_STAGING_DATA databases to another server as soon as possible.
B. Execute the DQS_MAIN.internal_core.InitServer stored procedure with the appropriate parameter.
C. Restore only the DQS_MAIN and DQS_STAGING_DATA databases to another server as soon as possible.
D. Execute the DQS_MAIN.internal_core.RestoreDQDatabases stored procedure with the appropriate parameter.
Answer: A,D
Explanation
Steps to restore DQS Databases:
* Restore DQS_MAIN database.
* Restore the DQS_PROJECTS database.
* Restore the DQS_STAGING_DATA database.
* In Object Explorer, right-click the server, and then click
* In the Query Editor window, copy the following SQL statements, and replace <PASSWORD> with the password that you provided during the DQS installation for the database master key:
USE [DQS_MAIN]
GO
EXECUTE [internal_core].[RestoreDQDatabases] '<PASSWORD>'
GO
* Press F5 to execute the statements. Check the Results pane to verify that the statements have executed successfully.
Note:
* Backup and restore of SQL Server databases are common operations that database administrators perform for preventing loss of data in a case of disaster by recovering data from the backup databases. Data Quality Server is primarily implemented by two SQL Server databases: DQS_MAIN and DQS_PROJECTS. The backup and restore procedures of the Data Quality Services (DQS) databases are similar to any other SQL Server databases.

QUESTION NO: 2
You are developing a data flow transformation to merge two data sources. One source contains product data and the other source contains data about the country in which the product was manufactured. Both data sources contain a two-character CountryCode column and both use
SQL Server. Both data sources contain an ORDER BY clause to sort the data by the CountryCode column in ascending order.
You use a Merge Join transformation to join the data.
You need to ensure that the Merge Join transformation works correctly without additional transformations.
What should you do? (Each answer presents a part of the solution. Choose all that apply.)
A. Set the MaxBuffersPerlnput property on the Merge Join transformation to 2.
B. set the appropriate SortKeyPosition properties on the data sources.
C. set the IsSorted property on both data sources.
D. set the ValidateExternalMetaData property on the Merge Join transformation to True.
Answer: B,C

QUESTION NO: 3
You deploy a server that has SQL Server installed.
You deploy a SQL Server Integration Services (SSIS) package to the server.

In which order should you perform all the actions? To answer, move all of the actions to the answer area and arrange them in the correct order.
NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.

QUESTION NO: 4
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. Run the package in Performance mode.
B. Increase the value of the Row per Batch property.
C. Partition the table by day and store.
D. Create a clustered index on the Transaction table.
Answer: B
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.

QUESTION NO: 5
You are designing a data warehouse with two fact tables. The first table contains sales per month and the second table contains orders per day.
Referential integrity must be enforced declaratively.
You need to design a solution that can join a single time dimension to both fact tables.
What should you do?
A. Merge the fact tables.
B. Create a surrogate key for the time dimension.
C. Join the two fact tables.
D. Create a time dimension that can join to both fact tables at their respective granularity.
Answer: D
