200-301 - Network Access - Section 2.1

Configure and verify VLANs (normal range) spanning multiple switches, including access ports for data and voice, the default VLAN, and interswitch trunk connectivity using 802.1Q and the native VLAN.

Segment a switched network into broadcast domains with VLANs, assign access ports for end devices, and carry multiple VLANs between switches over an 802.1Q trunk. Recognise that 802.1Q tags every VLAN except the native VLAN, that a native-VLAN mismatch on the two ends of a trunk breaks connectivity, and that a voice VLAN lets an IP phone and a PC share one access port.
