Network+ Certification : What it’s All About
Network+ certification, like other CompTIA offerings, is an entry-level and vendor neutral certification. This credential is designed for IT professionals who possess nine months of on-the-job experience in network administration or support. This certification is intended to demonstrate the candidate's knowledge of foundational networking concepts. According to CompTIA, over 150,000 networking professionals have achieved the Network+ certification. Network+ is a natural stepping stone toward more advanced credentials, such as the Microsoft MCSE and EC-Council CEH. There are no formal prerequisites for Network+, however, CompTIA recommends that candidates first achieve the A+ certification.
Network+ is a popular credential for system and network administrators. In order to achieve the certification, candidates must pass one conventional format exam which covers objectives such as: protocols, media and topologies, network implementation and network support. The Network+ Certification exam (N10-003), was originally introduced in 1997. The most recent update to this exam came in 2009. Similar to other CompTIA certifications, once a candidate achieves Network+, he/she is certified for life and the credential does not expire.
