As a Salesforce.com partner, Reside developers each have the task of becoming certified with SFDC.  Having recently taken the 401 Developer Exam - I can say that it is a challenging exam.  Here are some notes from my personal stack of flash cards to help you get prepared!

True/False

• Even if an app is visible, the app’s tabs won’t show up unless a profile has permissions to view the tabs & permissions to view the associated objects.
• All standard profiles get full access to a custom object when it is created.
• The dataloader cannot load more than 50k records @ a time.
• If a user is assigned to a standard profile, the only way to restrict acces is thru object-level security.
• Permissions on standard profiles are editable.
• Every workflow rule must be based on a single object you choose when you  create the rule.
• When object vs. record-level permissions conflict, the most restrictive settings win.
• When creating email templates, you can use any merge fields and they will appear in your email.
• Sharing rules can be created for both master & detail objects in a Master/Detail relationship.
• Sharing rules & role hierarchies can never be stricter than our org-wide defaults.
• Users assigned to roles get access to the data of all users who fall directly beneath them in the hierarchy.
• A detail object record has its own org-wide sharing settings.
• All objects user same org-wide options (private, public – read/write, public – read only)
• If you completely hide a tab user can no longer see any of the records
• It’s ok to set the assignee of a workflow task to a role, instead of a user.
