Background
You are the SharePoint server administrator for Contoso, Ltd. Contoso has a SharePoint 2010
environment hosted on SharePoint Online and a separate on-premises SharePoint 2010 farm. You
are preparing to upgrade the environments to newer versions of SharePoint. You are also planning
to support a hybrid on-premises/cloud deployment that will be available to customers, partners, and
third-party vendors.

http://contoso.sharepoint.com.
• The SharePoint Online Administration Center URL is
https://contoso.admin.sharepoint.com.
• The user name for the Contoso Office 365 administrator is
admin@contoso.com.
• An existing line-of-business application provides an OData service
that is hosted in Microsoft Windows Azure SQL Database.
The site collections are described in the following table.
