CompTIA Network+

The CompTIA Network+ certification (Exam N10-007) is an internationally recognized validation of the technical knowledge required of foundation-level IT network practitioners.

This exam will certify the successful candidate has the knowledge and skills required to troubleshoot, configure, and manage common network devices; establish basic network connectivity; understand and maintain network documentation; identify network limitations and weaknesses; and implement network security, standards, and protocols. The candidate will have a basic understanding of enterprise technologies, including cloud and virtualization technologies.

CompTIA Network+ is accredited by ANSI to show compliance with the ISO 17024 Standard and, as such, undergoes regular reviews and updates to the exam objectives.

Prerequisites

It is recommended for CompTIA Network+ candidates to have the following:

  • CompTIA A+ certification or equivalent knowledge, though CompTIA A+ certification is not required.
  • Have at least 9 to 12 months of work experience in IT networking.
