A: Dynamic Access Control introduces a new way to think about giving users access to data, which is based around user attributes being used to populate claims that match policies on classifications of data.

To use Dynamic Access Control, the forest functional level must be Windows Server 2003, and there must be at least one Windows Server 2012 (formerly code-named Windows Server 8) domain controller per domain.

See the Microsoft website for more details on Dynamic Access Control.
