The skills and knowledge for this certification are being
derived from an industry-wide job task analysis (JTA) and validated through
an industry-wide survey. The Network+ certification, covering the 2001
objectives, will certify that the successful candidate knows the layers
of the OSI model, can describe the features and functions of network components
and has 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.
In addition to A+ certification level knowledge, Network+ candidates are
encouraged to have at least 9 months of experience in network support or
administration.
The Network+ beta will be available
during 3 rd quarter 2001. It is anticipated that the
revised exam will launch early
4 th quarter 2001.
