B. Enable 802.1Q. D. Set up voice VLANs. Explanation: B. Enable 802.1Q: 802.1Q is a VLAN tagging protocol that allows multiple VLANs to be carried over a single physical link. Since the network is already segmented for computers and servers, enabling 802.1Q allows the switch ports to carry both data and voice traffic over the same physical connection, effectively supporting the new VoIP network without requiring additional switch ports. D. Set up voice VLANs: Voice VLANs are required to separate voice traffic from data traffic on the same network. This ensures that voice data is prioritized for quality and performance while keeping it logically isolated from other types of traffic, which is critical for VoIP performance.
