Build the advanced LAN and wide-area network skills that enterprise networks depend on. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, you'll start with switch management, VLANs, inter-VLAN routing, and 802.1Q trunking, then work with Cisco CLI commands, port security, DHCP snooping, dynamic ARP inspection, and IDS versus IPS. From there, you'll explore IPv6 address structure and IPv4-to-IPv6 transition, and finish with WAN connectivity, including MPLS, Metro Ethernet, broadband, satellite and cellular networking, and VPNs. Online labs reinforce switch configuration and VLAN tasks. Switch CLI practice and network device placement scenarios show how each piece fits together in a real network. Each module builds on the last, and the first module is designed as an accessible entry point. Expert instruction keeps each topic practical.

Not planning to take the exam? Switching, IPv6, and WAN skills connect your local network to everything else, and they apply on the job whether or not you pursue the certification.
