You are designing an application that will use a timer job that will run each night to send documents to a SharePoint 2010 Records Center site for archiving. The security on the site requires higher privileges than those normally associated with the application. The security requirements for this application specify that:

• It must not require customized storage of the user credentials.
• The user token used for security access must expire within 24 hours

unless specifically refreshed to prevent extended or unintended use over time.

• The security mechanism must require a two-way trust to prevent

unauthorized activity between domains.

• The application must use the SharePoint object model to accomplish

this. You need to design the application to support these security requirements. How should you design the timer job?
