You work as a senior database developer at ABC.com. The ABC.com network consists of a single domain
named ABC.com. ABC.com makes use of Microsoft SQL Server 2012 in their environment.
You are running a training exercise for Microsoft SQL Server 2012 junior developers. You are discussing the
ValidateExternalMetaData property for a data flow.
Which of the following represents the data type for this property?

You work as a senior database administrator at ABC.com. The ABC.com network consists of a single domain
named ABC.com. ABC.com makes use of Microsoft SQL Server 2012 in their environment.
You are running a training exercise for Microsoft SQL Server 2012 junior administrators. You are discussing the
use of Slowly Changing Dimension Transformation Outputs. One of the output options causes Derived Column
transformations to create columns for the expired row and the current row indicators.
Which option is the output that causes this?

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?

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?

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 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?

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?

To ease the debugging of packages, you standardize the SQL Server Integration Services (SSIS) package
logging methodology. The methodology has the following requirements:
Centralized logging in SQL Server
Simple deployment
Availability of log information through reports or T-SQL
Automatic purge of older log entries
Configurable log details

To facilitate the troubleshooting of SQL Server Integration Services (SSIS) packages, a logging methodology is
put in place. The methodology has the following requirements:
The deployment process must be simplified.
All the logs must be centralized in SQL Server.
Log data must be available via reports or T-SQL.
Log archival must be automated.
You need to configure a logging methodology that meets the requirements while minimizing the amount of
deployment and development effort. What should you do?

You are implementing a SQL Server Integration Services (SSIS) package that loads data hosted in a SQL
Azure database into a data warehouse. The source system contains redundant or inconsistent data. When the
package finds invalid data, the row containing the invalid data must be omitted but it must also be written to a
text file for further analysis. You need to establish the best technique to log these invalid rows while keeping the
amount of development effort to a minimum. What should you do?
