CompTIA Network + (2005) Examination
Monday, July 28th, 2008Duration: 5 Days or 10 Evenings
The skills and knowledge measured by this examination are derived from an
industry-wide Job Task Analysis (JTA) and validated through an industry wide,
lobal 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 as 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
