Microsoft are currently offering a second shot to resit any MCP exam taken between July 12 2015 and January 12, 2016 if you don’t pass on your first attempt. You must reschedule your free retake within 30 days of failing your MCP exam.
Microsoft has made some changes to the MCSA for Server 2012 and SQL 2012 by introducing electives. This I feel is good idea as it allows you to pick an exam that may be more relative to your job role. So in my case I will be taken the following mandatory exams:
70-410: Installing and Configuring Windows Server
70-411: Administering Windows Server 2012
and then I can decide to do 70-409: Server Virtualization with Windows Server Hyper-V and System Center.
