Explanation
SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) are the core protocols used by VoIP (Voice over IP) systems. Best practice is to isolate voice traffic from data traffic using a dedicated voice VLAN. This segmentation improves call quality by reducing congestion and broadcast interference, and it enhances security by limiting what devices can interact with the VoIP infrastructure. Connecting a WAP to a different switch addresses wireless access, not VoIP segmentation. A DMZ is used for publicly accessible servers, not internal voice traffic. Setting ports to 802.1q mode enables VLAN trunking, which is a mechanism used to carry multiple VLANs-but it alone does not create the voice VLAN.
