CompTIA Network+ validates the networking knowledge every IT professional needs: how networks are designed, configured, secured and troubleshot. It is a vendor-neutral foundation for networking, cloud and cybersecurity careers.
Who should get Network+?
- Help desk and IT support professionals
- Aspiring network administrators and engineers
- Future cybersecurity analysts who need networking fundamentals
- Cloud engineers who want stronger networking skills
Exam overview
Network+ is a single exam with multiple-choice and performance-based questions. The certification is valid for three years.
Exam details such as price, length and question count change periodically — always confirm current information on the official certification page before you book.
Exam domains
- Networking concepts — OSI model, ports and protocols, IP addressing, topologies and cloud networking
- Network implementation — routing, switching, VLANs and wireless
- Network operations — monitoring, documentation, high availability and disaster recovery
- Network security — common threats, hardening and secure access
- Network troubleshooting — methodology, cabling, connectivity and performance issues
Key topics to master
- OSI and TCP/IP models
- IPv4 subnetting and CIDR, plus IPv6 basics
- Common ports for SSH, DNS, DHCP, HTTP/HTTPS, email, SNMP, LDAP and RDP
- Switching: VLANs, trunking and spanning tree
- Routing: static vs. dynamic, OSPF and BGP basics
- Wireless standards and security
- DNS, DHCP, NAT and VPNs
- The troubleshooting methodology
Master subnetting
Subnetting appears in exams and interviews. Practice daily until you can quickly calculate network addresses, broadcast addresses, usable hosts and subnet masks. Flashcards and subnetting practice websites help.
A 6-week study plan
- Week 1: Networking models, ports and protocols
- Week 2: IP addressing and subnetting
- Week 3: Switching, routing and wireless
- Week 4: Network services, cloud and operations
- Week 5: Security and troubleshooting
- Week 6: Practice exams and simulations
Use Cisco Packet Tracer or GNS3 for hands-on labs.
Network+ vs. CCNA
Network+ is vendor-neutral and broad. CCNA goes deeper, includes Cisco configuration and is more respected for networking-specific roles. Many people take Network+ first, then CCNA. See how to become a network engineer.
What comes next
Security+ for security, CCNA for networking, or cloud certifications such as AWS Solutions Architect – Associate to apply networking skills in the cloud.
Frequently asked questions
Is Network+ worth it?
Yes for IT support and entry-level networking roles, and as a foundation for security and cloud careers.
Should I take A+ before Network+?
A+ is helpful but not required. If you already understand computer basics, you can start with Network+.
