Question #: 99
Topic #: 1

Suggested Answer: B,D Vote an answer

To support VoIP on a network with limited switchports, the engineer should configure voice VLANs and enable 802.1Q tagging. Voice VLANs allow VoIP traffic to be prioritized and isolated from data traffic even when sharing the same physical port. 802.1Q is used for VLAN tagging, enabling multiple VLANs over a single physical link.
From Andrew Ramdayal's guide:
"Voice VLANs allow IP phones and computers to share the same physical switch port while keeping their traffic separate. 802.1Q is used to tag VLAN traffic so that it can be appropriately routed and prioritized."
