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?
A. Create three software tables, dimSoftware, dimSoftwareCategory, and dimSoftwareSubcategory and a fourth bridge table that joins software titles to their appropriate category and subcategory table records with foreign key constraints. Direct the cube developer to use key granularity attributes.
B. Create three software tables, dimSoftware, dimSoftwareCategory, and dimSoftwareSubcategory. Connect factSales to all three tables and connect factTarget to dimSoftwareCategory with foreign key constraints. Direct the cube developer to use key granularity attributes.
C. Create one table, dimSoftware, which contains Software Detail, Category, and Subcategory columns. Connect factSales to dimSoftware with a foreign key constraint. Direct the cube developer to use a non-key granularity attribute for factTarget.
D. Create two tables, dimSoftware and dimSoftwareCategory. Connect factSales to dimSoftware and factTarget to dimSoftwareCategory with foreign key constraints. Direct the cube developer to use key granularity attributes.
Correct Answer: C

Your team is creating SQL Server Integration Services (SSIS) packages that have several dependencies. The packages use parameters for configuration purposes.
Your company\’s IT policies include the following change control requirements:
After a package is ready for deployment, your team must hand over the process to junior IT personnel.
The process must guarantee that when a package has been validated, that same package (and all its dependencies) is deployed to production. The process must be repeatable and reliable and must be executed with the least administrative
and training effort by junior IT personnel.
You need to use the most appropriate deployment unit to satisfy the company policies, while minimizing issues such as incorrect version or configuration.
Which type of deployment unit should you use?
B. SSIS deployment manifest
Correct Answer: D
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 2016.
Which tool should you use?
A. SQL Server Integration Services Deployment Wizard
B. SQL Server Configuration Manager
C. SSIS Upgrade Wizard in SQL Server Management Studio
D. SSIS Upgrade Wizard in SQL Server 2008 BIDS
Correct Answer: C
Explanation: You can upgrade packages that were created in earlier versions of Integration Services to the Integration Services format that SQL Server 2016 uses. SQL Server provides the SSIS Package Upgrade Wizard to help in this
process. Because you can configure the wizard to backup up your original packages, you can continue to use the original packages if you experience upgrade difficulties.
You can run the SSIS Package Upgrade Wizard from SQL Server Data Tools (SSDT), from SQL Server Management Studio, or at the command prompt.
* When you upgrade an instance of SQL Server 2005 or SQL Server 2008 to the current release of SQL Server, your existing SQL Server 2008 Integration Services (SSIS) packages are not automatically upgraded to the package format that the current release SQL Server Integration Services uses. You will have to select an upgrade method and manually upgrade your packages.
You are designing a SQL Server Integration Services (SSIS) 2016 package that imports data from a Windows Azure SQL Database database into a SQL Server database. The SSIS package has the following requirements:
Every night, a very large amount of data is imported into the staging database.
Package processing time must be minimized.
The package must run on its own dedicated server when it is deployed to production.
Transaction log activity when data is imported must be minimized.
You need to design the package to meet the requirements.
Which destination component should you use?
Correct Answer: B
