Complete CompTIA Network+ Curriculum
Browse all 23 interactive lessons across 5 curriculum chapters. Every lesson includes verified blueprint takeaways, common examination traps, and interactive practice checkpoints:
Networking Fundamentals
Master the OSI 7-layer architecture, IPv4 subnetting mathematics, IPv6 prefix architecture, standard TCP/UDP ports, network topologies, and copper and optical cabling media.
Network Implementations
Configure dynamic and static routing, administrative distance, enterprise switching, VLAN tagging, Spanning Tree Protocol, Power over Ethernet, modern Wi-Fi 6/6E standards, and cloud VPC architectures.
Network Operations
Master network monitoring using SNMPv3 and Syslog, flow analytics, baseline performance metrics, change management protocols, disaster recovery models, and high availability clustering.
Network Security
Examine Zero Trust architecture, threat vectors (MitM, ARP spoofing, DoS), Layer 2 switchport hardening, Next-Gen firewalls, 802.1X port control, AAA authentication, and IPsec VPN cryptography.
Network Troubleshooting
Master the CompTIA 7-step troubleshooting methodology, hardware testing instruments (OTDR, TDR, spectrum analyzers), CLI diagnostics (traceroute, netstat, dig, iperf), and real-world enterprise fault resolution.
