CompTIA Server+ Objectives

  1. 1. CompTIA Server+ (2009 Edition) Exam Objectives 1 of 14Copyright 2009 by the Computing Technology Industry Association. All rights reserved.The CompTIA Server+ (2009 Edition) Exam Objectives are subject to change without notice.CompTIA Server+ (2009 Edition) CertificationExamination ObjectivesINTRODUCTIONThe CompTIA Server+ (2009 Edition) certification is an international vendor neutralcredential. The Server+ exam is a validation of “foundation” level server skills andknowledge, 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 importanceof one domain relative to another.The CompTIA Server+ (2009 Edition) certification is targeted towards individuals with18-24 months of IT experience. Although not a prerequisite, it is recommended thatCompTIA Server+ candidates hold a CompTIA A+ certification.This test will certify that the successful candidate has the knowledge and skills requiredto build, maintain, troubleshoot and support server hardware and software technologies.The successful candidate will be able to identify environmental issues; understand andcomply with disaster recovery and physical / software security procedures; be familiarwith industry terminology and concepts; understand server roles / specializations andinteraction within the overall computing environment.The table below lists the domains measured by this examination and the appropriateextent to which they are represented.Domain % of Examination1.0 System Hardware 21%2.0 Software 19%3.0 Storage 14%4.0 IT Environment 11%5.0 Disaster Recovery 11%6.0 Troubleshooting 24%Total 100%**Note: The lists of examples provided in bulleted format below each objective are not exhaustivelists. Other examples of technologies, processes or tasks pertaining to each objective may alsobe included on the exam although not listed or covered in this objectives document.(A list of acronyms used in these Objectives appears at the end of this document.)
