CompTIA SK0-003 Exam (CompTIA Server+ Certification) Detailed Information

SK0-003 - CompTIA Server+ Certification

SK0-003 Test Objectives


Certification Exam Objectives: SK0-003

The CompTIA Server+ certification is an international vendor neutral credential. The CompTIA Server+ exam is a validation of “foundation” level server skills and knowledge, and is used by organizations and IT professionals around the globe.

The skills and knowledge measured by this examination are derived from an industry- wide Job Task Analysis (JTA) and were validated through a global survey in Q4, 2008. The results of the survey were used to validate the content of the subject areas (domains) and exam objectives, as well as the overall domain weightings, ensuring the importance of one domain relative to another.

The CompTIA Server+ certification is targeted towards individuals with 18-24 months of IT experience. Although not a prerequisite, it is recommended that CompTIA Server+ candidates hold a CompTIA A+ certification.

This test will certify that the successful candidate has the knowledge and skills required to build, maintain, troubleshoot and support server hardware and software technologies. The successful candidate will be able to identify environmental issues; understand and comply with disaster recovery and physical / software security procedures; be familiar with industry terminology and concepts; understand server roles / specializations and interaction within the overall computing environment.

The table below lists the domains measured by this examination and the appropriate extent to which they are represented.
