    CompTIA A+ Essentials (2009 Edition) Objectives
    Exam Number: 220-701
    Introduction
    In order to receive CompTIA A+ certification a candidate must pass two exams. The first exam is
    CompTIA A+ Essentials, exam number 220-701. The CompTIA A+ Essentials examination 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, networking, and security, and will have the skills
    required to identify hardware, peripheral, networking, and security components. Successful candidates will
    understand the basic functionality of the operating system 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
    regular reviews and updates to the exam objectives. The following CompTIA A+ Essentials objectives
    reflect the subject areas 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 represent 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, test objectives, and example content. Example
    topics and concepts are included 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 guide 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 table 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 Percentage of Examination
    1.0 Hardware 27%
    2.0 Troubleshooting, Repair & Maintenance 20%
    3.0 Operating System and Software 20%
    4.0 Networking 15%
    5.0 Security 8%
    6.0 Operational Procedure 10%
    Total 100%
    **Note: The lists of examples provided in bulleted format below each objective are not exhaustive lists. Other
    examples of technologies, processes or tasks pertaining to each objective may also be included on the exam although
    not listed or covered in this objectives document.
    CompTIA is constantly reviewing the content of our exams and updating test questions to be sure our
    exams are current and the security of the questions is protected. When necessary, we will publish updated
    exams based on existing exam objectives. Please know that all related exam preparation materials will still
    be valid.
