Network+ ( Networking
) ( Certified By CompTIA, USA)
Introduction
The skills and knowledge
measured by this examination are derived from an industry-wide
job task analysis (JTA) and validated through an industry
wide survey of which over 2,500 responses were received
in April 2001. The results of this survey were used
in weighing the domains and ensuring that the weighing
is representative of the relative importance of the
content.
The Network+ certification
covering the 2002 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 A+
certification or equivalent knowledge, but A+ certification
is not required, hi addition to A+ certification level
knowledge, candidates are encouraged to have at least
9 months of experience in network support or administration.
The 2002 objectives
update the Network+ certification exam on new technologies
such as wireless networking and gigabit Ethernet-
The scope of networking systems are broadened some
what placing an increased emphasis on Linux / Unix,
Windows 9x, Windows NT, Windows 2000 and including
AppleTalk as a network protocol There is also more
of an emphasis on hands-on experience knowledge needed
in the areas of network implementation and network
support including troubleshooting scenarios.
This examination includes
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.
