CompTIA and Network+ are trademarks of CompTIA. This course is not affiliated with or endorsed by CompTIA, and passing the exam is not guaranteed.

This self-paced course covers the objectives of the CompTIA Network+ (N10-009) exam across all five domains. It is built for learners with some hands-on networking experience who want to turn it into organized, certification-ready knowledge.

Learners study networking concepts, cloud and modern architectures, routing and switching, network operations, and security. The course closes with a structured troubleshooting methodology applied to cabling, service, and performance issues.

Target Audience

This course is written for IT support staff, help desk technicians, and early-career network technicians who have some hands-on networking experience, consistent with CompTIA's own recommendation of at least 9 to 12 months in the field, and who want to organize that experience into vendor-neutral, certification-ready knowledge. Basic computer literacy and familiarity with everyday IT support work are assumed. This course is not for complete beginners with no networking exposure at all, and it is not for experienced network administrators or engineers who already work fluently with dynamic routing, VLANs, and structured troubleshooting; those learners should look for an introductory course or a more advanced certification, respectively.

This course has a prerequisite

CompTIA recommends 9 to 12 months of hands-on networking experience.
