Revised Network+ Examination Objectives 2005 Version 1Introduction The skills and knowledge measured by this examination are derived from an industry-wide Job Task Analysis (JTA) and validated through an industry wide, global survey for which over 2,000 responses were received from Subject Matter Experts (SMEs) in Q2 2004. 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. The Network+ certification covering the 2005 objectives, certifies that the successful candidates knows the layers of the OSI model, can describe the features and functions of network components and has the skills needed to install, configure, and troubleshoot basic networking hardware peripherals and protocols. A typical candidate should have CompTIA A+ certification or equivalent knowledge, though A+ certification is not required. In addition to A+ certification level knowledge, candidates are encouraged to have at least nine months of work experience in network support or administration. The 2005 objectives update the Network+ certification exam on new technologies, protocols and cable standards and well as the removal of older and less common versions of the same. The 2005 objectives also include changes to the weightings and presentation of objectives within the domains to reflect changes in the activities of individuals in a networking position. There remains continued emphasis on hands-on experience knowledge needed in the areas of network implementation and network support including troubleshooting scenarios. This examination document includes exam blueprint, weighting, test objectives and example content. Example concepts are included to clarify the test objectives and should not be construed as a comprehensive listing of the content of the examination. The table below lists the domains measured by this examination and the extent to which they are represented in the examination.
