  • 1. CompTIA A+ 220-702 Objectives Version 2.0 1 of 16Copyright © 2008 by the Computing Technology Industry Association. All rights reserved.The CompTIA A+ 220-702 Objectives are subject to change without notice.CompTIA A+ Practical Application (2009 Edition)ObjectivesExam Number: 220-702IntroductionIn order to receive CompTIA A+ certification a candidate must pass two exams. The first exam is CompTIA A+Essentials, exam number 220-701. Objectives for the CompTIA A+ Essentials examination are available atwww.comptia.org. The CompTIA A+ 220-702 exam, Practical Application, is the second exam required in orderfor CompTIA A+ certification candidates to complete their certification in the 2009 Edition of CompTIA A+.The CompTIA A+ Practical Application exam measures the necessary competencies for an entry-level ITprofessional who has hands-on experience in the lab or the field. Successful candidates will have the skills requiredto install, configure, upgrade, and maintain PC workstations, the Windows OS and SOHO networks. The successfulcandidate will utilize troubleshooting techniques and tools to effectively and efficiently resolve PC, OS, and networkconnectivity issues and implement security practices. Job titles in some organizations which are descriptive of therole of this individual may be: Enterprise technician, IT administrator, field service technician, PC or Supporttechnician, etc. Ideally, the CompTIA A+ Practical Application candidate has already passed the CompTIA A+Essentials examination.CompTIA A+ is ISO 17024 Accredited (Personnel Certification Accreditation) and, as such, undergoes regularreviews and updates to the exam objectives. The following CompTIA A+ Practical Application objectives reflectthe subject areas in the 2009 Edition of this exam, and result from subject matter expert workshops and industry-wide survey results regarding the skills and knowledge required of an entry-level IT professional with some hands-on experience. The percentages in this document represent the relative importance of the subject areas (domains) inthe associated body of knowledge, and together establish the foundation for an entry-level IT professional.This examination blueprint includes domain weighting, test objectives, and example content. Example topics andconcepts are included to clarify the test objectives and should not be construed as a comprehensive listing of all thecontent of this examination.Candidates are encouraged to use this document to guide their studies. The contents of the examination blueprinthelp prioritize topics and provide a guide of what to expect on the CompTIA A+ Practical Application exam. Thetable below lists the domains measured by this examination and the extent to which they are represented. TheCompTIA A+ Practical Application (2009 Edition) exam is based on these objectives.Domain Percentage of Examination1.0 Hardware 38%2.0 Operating Systems 34%3.0 Networking 15%4.0 Security 13%Total 100%**Note: The lists of examples provided in bulleted format below each objective are not exhaustive lists. Other examples oftechnologies, processes or tasks pertaining to each objective may also be included on the exam although not listed or covered inthis objectives document.CompTIA is constantly reviewing the content of our exams and updating test questions to be sure our exams are current and thesecurity of the questions is protected. When necessary, we will publish updated exams based on existing exam objectives. Pleaseknow that all related exam preparation materials will still be valid.
