CompTIA A+ Essentials (2009 Edition) Objectives Exam Number 220-701 Introduction In say to receive CompTIA A+ certification a candidate must pass two trial runs. The first exam is CompTIA A+ Essentials, exam number 220-701. The CompTIA A+ Essentials scrutiny measures 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 field.Successful candidates will have the knowledge required to understand the fundamentals of computer technology, webing, and security, and will have the skills required to identify hardware, computer peripheral, networking, and security components. Successful candidates will understand the basic component partality of the operating body and basic troubleshooting methodology, practice proper safety procedures, and will effectively interact with customers and peers. CompTIA A+ is ISO 17024 Accredited (Personnel Certification Accreditation) and, as such, undergoes regul ar reviews and updates to the exam documentals.The following CompTIA A+ Essentials objectives reflect the subject heavenss in the 2009 Edition of the 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. The percentages in this document live the relative importance of the subject areas (domains) in the associated body of knowledge, and together establish the foundation of an entry-level IT professional. This examination blueprint includes domain weighting, exam objectives, and example content.Example topics and concepts are include to clarify the test objectives and should not be construed as a comprehensive listing of all the content of this examination. Candidates are encouraged to use this document to decease their studies. The contents of the examination blueprint help prioritize topics and provide a guide of what to expect on the CompTIA A+ Essentials exam. The p rorogue below 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. Domain 1. 0 2. 0 3. 0 4. 0 5. 0 6.
