Multiple Choice

Which technology should be configured on the network to ensure VoIP calls get priority over other traffic?

VoIP calls are real-time and sensitive to latency, jitter, and packet loss, so you need a way to ensure voice traffic gets preferential treatment on the network. Quality of Service provides exactly that: it classifies traffic, marks packets for priority, and enforces rules that reserve bandwidth and place voice in high-priority queues. This helps keep VoIP latency low and jitter minimal, preserving call quality. Other technologies listed don’t focus on traffic prioritization. A VPN secures and tunnels traffic, DNS translates domain names to IP addresses, and NAT changes IP addresses for routing. None of these directly ensure voice packets are treated with priority or guaranteed bandwidth.
