Topic 6, WingTip Toys
General Background
You are a data architect for WingTip Toys. The company uses SQL Server 2012 Enterprise
edition. SQL Server Analysis Services (SSAS) and SQL Server Reporting Services (SSRS)
are installed on separate servers.
Data Warehouse
The company's data warehouse initially contained less than 100 MB and 100 million rows
of data from only one data source. It now contains more than 10 TB and 10 billion rows of
data, in 25 tables, from 12 data sources.
The largest table in the data warehouse, the factOrders table, contains 5 TB of data. The
OrderDateKey InvoiceDateKey, and
ShipDateKey. The data warehouse server has 1 TB of RAM. Memory usage is currently at
20 percent.
One billion rows of data are added to the data warehouse each month. New data is copied
each night from the data sources into SQL Server staging tables, and existing records are
not updated. The largest data set is order information, which is loaded in parallel into
multiple staging tables, one for each data source. All the staging tables have the same
structure and belong to the same filegroup as the factOrders table.
The dimCustomers table stores customer information that may change over time.
Data Models
You are developing three SSAS databases, as described in the following table.
Reporting
Business users frequently generate reports in Microsoft Excel by using PowerPivot. The
PowerPivot Management Dashboard does not currently display any usage data.
Several SSRS reports exist that use the data warehouse as a source. The data warehouse
queries are aggregate queries that use the factOrders table and one or more dimension
tables. All SSRS data sources use Integrated Windows authentication.
SSRS displays a security access error message when managers run SSRS reports based
on the Operations database.
Reporting performance has become unacceptably slow.
Business Requirements

Topic 7, Contoso, Ltd Case B
General Background
You are the business intelligence (BI) solutions architect for Contoso, Ltd, an online
retailer.
You produce solutions by using SQL Server 2012 Business Intelligence edition and
Microsoft SharePoint Server 2010 Service Pack 1 (SP1) Enterprise edition.
A SharePoint farm has been installed and configured for intranet access only. An Internet-
facing web server hosts the company's public e-commerce website. Anonymous access is
not configured on the Internet-facing web server.
Data Warehouse
The data warehouse is deployed on a 5QL Server 2012 relational database instance. The
data warehouse is structured as shown in the following diagram.
The following Transact-SQL (T-SQL) script is used to create the FactSales and
The FactPopulation table is loaded each year with data from a Windows Azure Marketplace
commercial dataset. The table contains a snapshot of the population values for all
countries of the world for each year. The world population for the last year loaded exceeds
6.8 billion people.
ETL Process
SQL Server Integration Services (SSIS) is used to load data into the data warehouse. All
SSIS projects are developed by using the project deployment model.
A package named StageFactSales loads data into a data warehouse staging table. The
package sources its data from numerous CSV files exported from a mainframe system.
The CSV file names begin with the letters GLSD followed by a unique numeric identifier
that never exceeds six digits. The data content of each CSV file is identically formatted.
A package named LoadFactFreightCosts sources data from a Windows Azure SQL
Database database that has data integrity problems. The package may retrieve duplicate
rows from the database.
The package variables of all packages have the RaiseChangedEvent property set to true.
A package-level event handler
You need to identify the reasons that data alert notifications are not being sent.
Which of the following reasons are possible? (Each correct answer presents a complete solution. Choose al that apply.)
- A. The shared schedule is paused.
- B. The data source used by the report is disabled.
- C. The SSRS service is not running.
- D. The report data has not changed since the previous notification
- E. The SQL Server Agent is not running.
- F. The SSRS encryption key has been deleted.
Answer : C,E
Explanation:
One possibility is that no SQL Server Agent alerts have been configured. This is a free, easy way to get notified of corruption, job failures, or major outages even before monitoring systems pick it up.
