    CompTIA Network+ (2009 Edition) Certification Examination Objectives
    INTRODUCTION
    The CompTIA Network+ (2009 Edition) certification is an internationally recognized validation of the technical knowledge required of foundation-level IT network practitioners.
    The CompTIA Network+ (2009 Edition) certification ensures that the successful candidate has the important knowledge and skills necessary to manage, maintain, troubleshoot, install, operate and configure basic network infrastructure, describe networking technologies, basic design principles, and adhere to wiring standards and use testing tools.
    The skills and knowledge measured by this examination were derived from an industry-wide job task analysis and validated through an industry-wide global survey in Q2 2008. The results of this survey were used in weighing the domains and ensuring that the weighting is representative of the relative importance of the content.
    It is recommended for CompTIA Network+ (2009 Edition) candidates to have the following:

    CompTIA A+ certification or equivalent knowledge, though CompTIA A+ certification is not required.

    Have at least 9 to 12 months of work experience in IT networking.
    The table below lists the domains measured by this examination and the extent to which they are represented. CompTIA Network+ (2009 Edition) exams are based on these objectives.
