Microsoft wrote: For many years passing just one exam would give you the Microsoft Certified Professional (MCP) certification. The entry level MCP certification has been replaced by Microsoft Technology Associate (MTA) Only passing a MTA exams will give you the MTA certification. This means that any other exam in most cases will no longer give you entry level certification.
Q.What do I gain from passing a Microsoft Certification exam? A.When you pass your first Microsoft Certification exam, you become a member of the Microsoft Certified Professional (MCP) community with access to all of the benefits provided through the Microsoft Certification Program and the MCP member site. You can share your transcript with others to prove that you passed that exam and show your progress towards a specific certification. In some cases, such as when you pass an MTA or Specialist exam, that single exam will also earn you the associated certification.
