A vendor-neutral certification validating the networking knowledge and skills needed to design, configure, manage, and troubleshoot wired and wireless networks. Network+ is widely used as an entry point into networking-focused IT roles and is frequently listed as a prerequisite or preferred qualification alongside CompTIA A+ for help desk, network administration, and junior systems administration positions.
Who it's for
IT professionals early in their networking career, help desk and support technicians looking to move into network administration, and anyone needing a vendor-neutral networking credential recognized across employers who use a mix of Cisco, Juniper, and other networking hardware. It's commonly positioned as the natural next step after CompTIA A+, and a common prerequisite before pursuing vendor-specific certifications like Cisco's CCNA.
What's covered
- Networking Concepts (23%) — OSI model, network topologies, cloud concepts, ports and protocols, IPv4/IPv6 addressing and subnetting
- Networking Implementation (20%) — routing technologies, switching technologies, wireless standards, and physical/virtual network device deployment
- Networking Operations (19%) — network documentation, monitoring, business continuity, disaster recovery, and performance metrics
- Network Security (14%) — security concepts, network hardening techniques, remote access methods, and physical security
- Network Troubleshooting (24%) — a structured troubleshooting methodology applied to cabling, wireless, and network service issues
What to expect
The current Network+ exam (N10-009) has a maximum of 90 questions, drawing on multiple-choice, drag-and-drop, and performance-based question formats, with a 90-minute time limit. The passing score is 720 on a scale of 100-900. Network Troubleshooting is the single largest domain, reflecting CompTIA's emphasis on applying a consistent troubleshooting methodology rather than just recalling definitions.
How to prepare
Because subnetting and IP addressing questions require fast, accurate mental math under time pressure, candidates typically need dedicated subnetting practice separate from general concept review — this is one of the few areas of the exam where speed matters as much as knowledge. Troubleshooting questions reward memorizing CompTIA's structured troubleshooting methodology (identify the problem, establish a theory, test the theory, establish a plan, implement the solution, verify functionality, document findings) as a repeatable framework rather than solving each scenario from first principles.
