CompTIA A+ Essentials (2009 Edition) Objectives Exam Number 220-701 Introduction In order to receive CompTIA A+ certification a candidate must(prenominal) pass two tests. The first trial is CompTIA A+ Essentials, exam soma 220-701. The CompTIA A+ Essentials examination mea certain(predicate)s necessary competencies for an entry-level IT professional with the equivalent knowledge of at least 500 hours of hands-on experience in the lab or knowledge domain.Successful candidates leave behind have the knowledge required to understand the fundamentals of ready reckoner applied science, networking, and protective cover, and will have the skills required to identify hardw atomic number 18, peripheral, networking, and security components. Successful candidates will understand the basic functionality of the operating administration and basic troubleshooting methodology, practice fit safety procedures, and will effectively interact with clients and peers. CompTIA A+ is ISO 17024 Acc redited (Personnel authentication Accreditation) and, as much(prenominal), undergoes regular reviews and updates to the exam objectives.The following CompTIA A+ Essentials objectives reflect the candid beas in the 2009 Edition of the exam and result from overt matter respectable workshops and industry-wide survey results regarding the skills and knowledge required of an entry-level IT professional. The percentages in this account represent the coitus importance of the subject neighborhoods (domains) in the associated body of knowledge, and together establish the foundation of an entry-level IT professional. This examination blueprint includes domain weighting, test objectives, and example content.Example topics and concepts ar include to clarify the test objectives and should not be construed as a oecumenical listing of all the content of this examination. Candidates are encouraged to use this document to guide their studies. The contents of the examination blueprint help prioritize topics and leave behind a guide of what to expect on the CompTIA A+ Essentials exam. The table beneath lists the domains measured by this examination and the extent to which they are represented. The CompTIA A+ Essentials (2009 Edition) exam is based on these objectives.
