Network Fundamentals — CompTIA Network+ (N10-009) Practice Questions
Network fundamentals is the broadest domain on the N10-009 exam and covers the conceptual building blocks that underpin every other topic. It includes the OSI and TCP/IP models, IP addressing (IPv4 and IPv6), subnetting, common ports and protocols, and the purpose of core network services such as DNS and DHCP. A strong grasp of network fundamentals is essential because exam questions across all other domains assume you can apply this baseline knowledge to diagnose and design networks.
