Microsoft Certified Solutions Associate (MCSA) certifications are the foundation of Microsoft’s new generation of cloud-optimized credentials. Each MCSA certificate demonstrates your ability to design and create technology.
The latest MCSA credentials (Server 2012, SQL Server 2012 and Windows 8) do a good job of covering key skills from the older software versions (Server 2008, SQL Server 2008 & Windows 7), so unless your employer specifically requests the old version, always pursue the newest cert, even if the new software isn't widely adopted yet. You're getting certified for your future career, not your past.
