N10-009 - Network Implementation - Section 2.1
Configure and deploy common Ethernet switching features, including VLANs, trunking, spanning tree, and port security.
Configure VLANs and 802.1Q trunk links to segment broadcast domains, and apply inter-VLAN routing where hosts on different VLANs must communicate. Deploy spanning tree (STP/RSTP) to prevent switching loops, and harden access ports with port security, DHCP snooping, and the correct native-VLAN and tagging configuration.
