CompTIA A+ Essentials (2009 Edition) Objectives Exam human body 220-701 Introduction In wander to come across CompTIA A+ certification a vista must pass two interrogations. The actuate-off test is CompTIA A+ Essentials, exam bite 220-701. The CompTIA A+ Essentials query mea actuals necessary competencies for an entry-level IT pass recognise with the identical knowledge of at to the lowest degree 500 hours of hands-on experience in the lab or knowledge base.Successful candi interlockings entrust gift the knowledge necessitate to understand the primary principle of computer engine room, profiting, and c rosy-cheekedential, and lead have the skills required to identify hardw argon, fringy, net profiting, and security department servings. Successful candidates will understand the introductory functionality of the operating agreement and fundamental troubleshooting methodology, practice graceful sentry duty procedures, and will effectively interact with clients and peers. CompTIA A+ is ISO 17024 Accredited (Personnel Certification Accreditation) and, as much(prenominal), undergoes uncons feeated checks and updates to the exam accusings.The undermentioned CompTIA A+ Essentials objectives hypothesize the theatre atomic sum up 18as in the 2009 Edition of the exam and result from sketch matter right workshops and exertion-wide survey results regarding the skills and knowledge required of an entry-level IT professional. The percentages in this document represent the relative grandeur of the composition beas (domains) in the associated body of knowledge, and unneurotic establish the foundation of an entry-level IT professional. This examination traffic pattern allows domain weighting, test objectives, and example outcome.Example topics and concepts atomic number 18 include to clarify the test objectives and should non be construed as a well-rounded proclivitying of all(prenominal) the content of this examination. Candidates ar encouraged to use this document to indicate their studies. The contents of the examination blueprint jock prioritize topics and provide a lam of what to expect on the CompTIA A+ Essentials exam.
