What are two possible ways to achieve this goal?

You have a sandboxed SharePoint 2010 application for managing sales proposals. The
application runs in a hosted environment that does not allow direct access to external
services or the installation of proxies or external content types. The account status for your
application is contained in a Customer Relationship Management (CRM) system hosted on
a separate server. The account status information is exposed via Web services. You need
to display account status from the CRM system in the form of dashboards, pie charts, and
other reports to the users within your firewall. What are two possible ways to achieve this
goal? (Each correct answer presents a complete solution. Choose two.)

Develop a Silverlight component that is responsible for making the Web service call from
