Exam Code: 70-463
Total Questions: 230 Q&As
QUESTION 1
You are developing a project that contains multiple SQL Server Integration Services (SSIS) packages. The packages will be deployed to the SSIS catalog. One of the steps in each package accesses an FTP site to download sales transaction data.
You create project parameters to store the username and password that are used to access the FTP site.
You need to ensure that the username and password values are encrypted when they are deployed.
What should you do?
A. Set the Sensitive property of the parameters to True.
B. Set the ProtectionLevel property of the package to EncryptSensitiveWithUserKey.
C. Change the parameters to package parameters.
D. Change the project to the Legacy Deployment model.
Correct Answer: A
QUESTION 2
A SQL Server Integration Services (SSIS) package on a computer is failing periodically in production. The package was created less than one year ago and was deployed to the SSIS catalog.
Sometimes the package is started on a SQL Agent schedule; sometimes the package is started manually by an SSIS developer by using the Object Explorer in SQL Server Management Studio.
You need to identify the authenticated user responsible for starting the package each time it failed in the past.
Where can you find this information?
A. the SQL Server Log
B. the SSISDB.[catalog].[executions] view
C. the SSISDB.[catalog].[event_messages] view
D. the SQL Agent Job History
E. the SQL Agent Error Log
Correct Answer: B
QUESTION 3
You develop a SQL Server Integration Services (SSIS) package that imports SQL Azure data into a data warehouse every night.
The SQL Azure data contains many misspellings and variations of abbreviations. 70-463 dumps To import the data, a developer used the Fuzzy Lookup transformation to choose the closestmatching string from a reference table of allowed values. The number of rows in the reference table is very large.
If no acceptable match is found, the Fuzzy Lookup transformation passes a null value.
The current setting for the Fuzzy Lookup similarity threshold is 0.50.
Many values are incorrectly matched.
You need to ensure that more accurate matches are made by the Fuzzy Lookup transformation without degrading performance.
What should you do?
A. Change the Exhaustive property to True.
B. Change the similarity threshold to 0.55.
C. Change the similarity threshold to 0.40.
D. Increase the maximum number of matches per lookup.
Correct Answer: B
QUESTION 4
You are using SQL Server Data Tools to develop a SQL Server Integration Services (SSIS) project.
The first package that you create in this project contains a package connection that accesses a flat file. Additional packages in the project must also access this file.
You need to define and reuse the flat file connection in all project packages.
What should you do?
A. Convert the package Connection Manager in the first package to a project Connection Manager.
B. Copy the package Connection Manager and paste it into the second package.
C. Convert the project to the Package Deployment model.
D. Set the ProtectionLevel property of the package Connection Manager to DontSaveSensitive to reuse the flat file connection.
Correct Answer: A
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. Depending on the value in a source column, the package redirects rows to one of five different data flow paths.
You need to add a data flow transformation to support the package redirection.
Which data flow transformation should you use?
A. Conditional Split
B. pjvot
C. Multicast
D. Lookup
Correct Answer: A
QUESTION 6
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. Create a time mapping table.
B. Change the level of granularity in both fact tables to be the same.
C. Merge the fact tables.
D. Create a view on the sales table.
Correct Answer: C
QUESTION 7
You are editing a SQL Server Integration Services (SSIS) package that contains a task with a sensitive property.
You need to create a project parameter and configure it so that its value is encrypted when it is deployed to the SSIS catalog.
Which three steps 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.)
Correct Answer:
QUESTION 8
You develop and deploy a SQL Server Integration Services (SSIS) package.
The package is stored in the file system. 70-463 dumps

What should you use to execute the package? (Each correct answer presents a complete solution. Choose all that apply.)
A. catalog.start_package
B. dtexec
C. SQL Server Management Studio
D. SQL Server Agent
Correct Answer: B,D

Which tool should you use?
A. SSIS Upgrade Wizard in SQL Server 2008 BIDS
B. SSIS Upgrade Wizard in SQL Server Data Tools
C. SQL Server DTExecUI utility (dtexecui.exe)
D. SQL Server dtexec utility (dtexec.exe)
Correct Answer: B
QUESTION 10
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 junk dimension for the geography dimension.
B. Implement change data capture.
C. Create a conformed dimension for the geography dimension.
D. Create three geography dimensions.
Correct Answer: C
QUESTION 11
You are designing a data warehouse hosted on SQL Azure. The data warehouse currently includes the dimUser and dimDistrict dimension tables and the factSales fact table. The dimUser table contains records for each user permitted to run reports against the warehouse; and the dimDistrict table contains information about sales districts.
The system is accessed by users from certain districts, as well as by area supervisors and users from the corporate headquarters.
You need to design a table structure to ensure that certain users can see sales data for only certain districts. Some users must be permitted to see sales data from multiple districts.
What should you do?
A. Add a district column to the dimUser table.
B. Partition the factSales table on the district column.
C. Create a userDistrict table that contains primary key columns from the dimUser and dimDistrict tables.
D. For each district, create a view of the factSales table that includes a WHERE clause for the district.
Correct Answer: C
QUESTION 12
You are reviewing the design of a customer dimension table in an existing data warehouse hosted on SQL Azure.
The current dimension design does not allow the retention of historical changes to customer attributes such as Postcode.
You need to redesign the dimension to enable the full historical reporting of changes to multiple customer attributes including Postcode.
What should you do?
A. Add StartDate and EndDate columns to the customer dimension.
B. Add an IsCurrent column to the customer dimension.
C. Enable Snapshot Isolation on the data warehouse.
D. Add CurrentValue and PreviousValue columns to the customer dimension.
Correct Answer: A
