These objectives are up to date for the 2009 edition of the CompTIA Network+ exam.

The Network+ certification ensures that the successful candidate has the important knowledge and skills necessary to manage, maintain, troubleshoot, install, operate and configure basic network infrastructure, describe networking technologies, basic design principles, and adhere to wiring standards and use testing tools.

The skills and knowledge measured by this examination were derived from an industry-wide job task analysis and validated through an industry-wide global survey in Q2 2008. 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 table to the right lists the domains measured by this examination and the extent to which they are represented. Network+ exams are based on these objectives.

Note: The bulleted lists below each objective are not exhaustive lists. Even though they are not included in this document, other examples of technologies, processes, or tasks pertaining to each objective may also be included on the exam.
