Quick Answer

Subnet IPv4/IPv6, read a routing table, and match OSI layers to devices. Get VLANs and 802.1Q trunking right: verify with show vlan brief and show interfaces trunk on Cisco switches.

Networking Concepts is 23% of N10-009, covering OSI models, IPv4/IPv6 addressing, switching, routing, wireless, and cloud. Expect drag-and-drop, multiple-choice, and performance-based questions where you subnet, select ports, or identify a topology. You must apply concepts, not just recall definitions.
