A company's VoIP phone connection is cutting in and out. A senior network engineer is recommending the implementation of a voice VLAN. Which of the following should be configured?

The correct answer is A. 802.1Q tagging. A voice VLAN relies on IEEE 802.1Q to tag voice traffic with its own VLAN ID, letting switches differentiate and prioritize VoIP packets separately from data traffic. This segmentation reduces contention and stabilizes call quality.
