[2020.9] Popular Microsoft 70-767 exam practice questions (1-5)
QUESTION 1
You are implementing a SQL Server Integration Services (SSIS) package that imports Microsoft Excel workbook data
into a Windows Azure SQL Database database. The package has been deployed to a production server that runs
Windows
Server 2008 R2 and SQL Server 2016.
The package fails when executed on the production server.
You need to ensure that the package can load the Excel workbook data without errors. You need to use the least
amount of administrative effort to achieve this goal.
What should you do?
A. Install a 64-bit ACE driver and execute the package by using the 64-bit run-time option.
B. Enable Address Windowing Extensions (AWE) for the local SQL Server instance.
C. Replace the SSIS Excel source with an SSIS Flat File source.
D. Install a 64-bit ACE driver and replace the Excel source with an OLE DB source.
Correct Answer: D
Explanation: XLSX files, the new file type in Excel 2007/2010 cannot be opened with Excel Source/Destination in SSIS.
To use XLSX in SSIS we need to install the ACE driver and use OLE DB Source/Destination to read/write data in
XLSX
files.
ACE is a set of components that facilitate the transfer of data between existing Microsoft Office files such as Microsoft
Office Access (*.mdb and *.accdb) files and Microsoft Office Excel 7 (*.xls, *.xlsx, and *.xlsb) files to Microsoft SQL
Server.
If the SQL Server or your development box does not have an ACE driver then install that 1st.
Note:
*
The most efficient way to link to SQL Server is using an OLEDB connection manager.
Incorrect: Not B:
*
Address Windowing Extensions (AWE) is a Microsoft Windows application programming interface that allows a 32-bit
software application to access more physical memory than it has a virtual address space.
*
Address Windowing Extensions (AWE) is a set of extensions that allows an application to quickly manipulate physical
memory greater than 4GB. Certain data-intensive applications, such as database management systems and scientific
and engineering software, need access to very large caches of data. In the case of very large data sets, restricting the cache to fit within an application\\’s 2GB of user address space is a severe restriction.
QUESTION 2
A company plans to load data from a CSV file that is stored in a Microsoft Azure Blob storage container.
You need to load the data.
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to
the correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need to
drag
the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Correct Answer:
QUESTION 3
You are installing SQL Server Data Quality Services (DQS).
You need to give specific users access to the Data Quality Server.
Which SQL Server application should you use?
A. SQL Server Configuration Manager
B. SQL Server Data Tools
C. SQL Server Management Studio
D. Data Quality Client
Correct Answer: C
Ref: http://msdn.microsoft.com/en-us/library/hh213045.aspx
QUESTION 4
The package uses data from the Products table and the Prices table. Properties of the Prices source are shown in the
OLE DB Source Editor exhibit (Click the Exhibit button.) and the Advanced Editor for Prices exhibit (Click the Exhibit
button.)
You create a Microsoft SQL Server Integration Services (SSIS) package as shown in the SSIS Package exhibit. (Click
the Exhibit button.)
You join the Products and Prices tables by using the reference column.
You need to resolve the error with the package.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
There are two important sort properties that must be set for the source or upstream transformation that supplies data to
the Merge and Merge Join transformations:
The Merge Join Transformation requires sorted data for its inputs.
If you do not use a Sort transformation to sort the data, you must set these sort properties manually on the source or the upstream transformation.
References: https://docs.microsoft.com/en-us/sql/integration-services/dataflow/transformations/sort-data-for-the-mergeand-merge-join-transformations
QUESTION 5
You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy.
The package reads data from a source system that uses the SQL Server change data capture (CDC) feature.
You have added a CDC Source component to the data flow to read changed data from the source system.
You need to add a data flow transformation to redirect rows for separate processing of insert, update, and delete
operations.
Which data flow transformation should you use?
A. Audit
B. DQS Cleansing
C. CDC Splitter
D. Pivot
Correct Answer: C
Explanation: The CDC splitter splits a single flow of change rows from a CDC source data flow into different data flows
for Insert, Update and Delete operations Ref: http://msdn.microsoft.com/en-us/library/hh758656.aspx

[2020.9] Popular Microsoft 70-768 exam practice questions (1-5)
QUESTION 1
You are a business analyst for a company that uses a Microsoft SQL Server Analysis Services (SSAS) tabular database
for reporting. The database model contains the following tables:
You have been asked to write a query for a report that returns the total sales for each product subcategory, as well as
for each product category.
You need to write the query to return the data for the report.
How should you complete the DAX statement? To answer, drag the appropriate DAX segment to the correct locations.
Each DAX segment may be used once, more than once, or not at all. You may need to drag the split bar between panes
or
scroll to view content.
Select and Place:
Correct Answer:
Box 1:EVALUATE
Box 2:SUMMERIZE
Box 3:ROLLUP
Box 4:\\’Product Subcategory\\’ [\\’Product Subcategory Name]
Note: The behavior of SUMMARIZE is similar to the GROUP BY syntax of a SELECT statement in SQL. For example,
consider the following query.
EVALUATE
SUMMARIZE(
\\’Internet Sales\\’,
\\’Internet Sales\\'[Order Date],
“Sales Amount”, SUM( \\’Internet Sales\\'[Sales Amount] )
)
This query calculates the total of Sales Amount for each date in which there is at least one
order,
producing this result.
QUESTION 2
You are developing a SQL Server Analysis Services (SSAS) tabular project that will be used by the finance, sales, and
marketing teams.
The sales team reports that the model is too complex and difficult to use. The sales team does not need any information
other than sales related resources in the tabular model. The finance and marketing teams need to see all the resources
in the tabular model.
You need to implement a solution that meets the needs of the sales team while minimizing development and
administrative effort. What should you do?
A. Create a separate partition for each team.
B. Create a separate data source for each team.
C. Create a perspective for the sales team.
D. Enable client-side security to filter non-sales data.

You need to create the cube processing job and the dimension processing job. Which processing task should you use
for each job? To answer, drag the appropriate processing tasks to the correct locations. Each processing task may be
used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Select and Place:
Box 1: ProcessData Processes data only without building aggregations or indexes. If there is data is in the partitions, it
will be dropped before re-populating the partition with source data. Box 2: Process Update Forces a re-read of data and
an update of dimension attributes. Flexible aggregations and indexes on related partitions will be dropped. References: https://docs.microsoft.com/en-us/sql/analysis-services/multidimensionalmodels/processing-options-and-settings-analysisservices
QUESTION 4
You install a SQL Server Analysis Services (SSAS) instance in tabular mode on a server.
While processing a very large tabular model, you receive an out-of-memory error. You identify that the amount of
