Yes - anyone can take the 70-432 SQL Server 2008 Implementation and Maintenance exam. Be sure to study hard; there are no refunds for any Microsoft exam.
You will be certified for life on this topic. It will be tied to your Microsoft Certified Professional (MCP) ID.
The SQL Server 2012 exams are not for life. You will need to recertify every three (3) years with the latest released version of SQL Server.
After you pass 70-432, you can pass the 70-448 Business Intelligence exam to earn the title:
MCSA: SQL Server 2008
This title is for life and does not require recertification.
Here are the two exam descriptions:
