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?
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. To import the data, a developer used the Fuzzy Lookup transformation to choose the closest-matching 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?
You install a SQL Server 2012 database engine instance on a production server. A month later, you install
SQL Server 2012 Integration Services (SSIS).
You must develop an SSIS project and deploy it to the server by using the Project Deployment model.
Operations Log records that are outside the configured retention period must be cleaned automatically.
You need to create the SSIS catalog on the production server and ensure that the operations log cleaning requirement is met.
What should you do? (Each correct answer presents part of the solution. Choose all that apply.)
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?
You maintain a SQL Server Integration Services (SSIS) package. The package was developed by using
SQL Server 2008 Business Intelligence Development Studio (BIDS).
The package includes custom scripts that must be upgraded.
You need to upgrade the package to SQL Server 2012.
Which tool should you use?
You are reviewing the design of an existing fact table named factSales, which is loaded from a SQL Azure database by a SQL Server Integration Services (SSIS) package each day. The fact table has approximately 1 billion rows and is dimensioned by product, sales date, and sales time of day.
The database administrator is concerned about the growth of the database. Users report poor reporting performance against this database. Reporting requirements have recently changed and the only remaining report that uses this fact table reports sales by product name, sale month, and sale year. No other reports will be created against this table.
You need to reduce the report processing time and minimize the growth of the database.
What should you do?
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?
You are designing a data warehouse for a software distribution business that stores sales by software title.
It stores sales targets by software category. Software titles are classified into subcategories and categories. Each software title is included in only a single software subcategory, and each subcategory is included in only a single category. The data warehouse will be a data source for an Analysis Services cube.
The data warehouse contains two fact tables:
factSales, used to record daily sales by software title factTarget, used to record the monthly sales targets by software category
Reports must be developed against the warehouse that reports sales by software title, category and subcategory, and sales targets.
You need to design the software title dimension. The solution should use as few tables as possible while supporting all the requirements.
What should you do?
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?
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.
