Sun’s Certified Systems Administrator for the Solaris 9 Operating Environment (SCSA) is meant for “system administrators tasked with performing essential system administration procedures on the Solaris Operating Environment (Solaris OE) and technical application support staff responsible for administering a networked server running on the Solaris OE.†These candidates should have a minimum of six months experience as system administrators to take the first of two exams required for this certification and twelve months experience for the second exam. There are no prerequisites for this certification, although Sun recommends a deep understanding of basic Unix and Solaris OE commands. It is a requirement for the Sun Certified Network Administrator for the Solaris Operating Environment exam.
This certification is well suited to IT professionals who are systems or network administrators in a UNIX environment as well as to those candidates who want to form a solid foundation for UNIX network security.
For candidates who are already SCSA’s for one of these prior versions of Solaris OE (2.5, 2.6, 7, 8), they may take one exam, the Sun Certified System Administrator for the Solaris 9 Operating Environment Upgrade Exam, number CX-310-016, to upgrade to version 9 of the certification.
Sun certification exams taken after September 1, 2002 are “valid for two (2) years from the date of certification. Despite the two-year validity date, Sun does not presently plan to revoke certification titles already held by a professional if the validity date of a specific certification has passed.“
