Which network feature ensures data delivery and high-priority applications run smoothly even under limited capacity?

Which network feature ensures data delivery and high-priority applications run smoothly even under limited capacity?

• A. Quality of Service (QOS)
• B. Privacy
• C. RFI
• D. Recovery (Cold Site)

Answer: (A)

Prioritizing traffic to guarantee essential services get the bandwidth they need is what Quality of Service provides. QoS classifies traffic into priority tiers and applies rules for how bandwidth is allocated, queued, and scheduled. By marking certain packets and reserving or prioritizing bandwidth for critical applications (like VoIP, video conferencing, or key business transactions), it helps ensure data delivery and smooth performance even when the network is congested or capacity is limited. Privacy aims to protect data confidentiality, not manage traffic flow. RFI (radio frequency interference) refers to unwanted signals disrupting wireless communication, not a network traffic-management mechanism. Recovery with a Cold Site is a disaster-recovery solution, not a real-time mechanism to ensure performance during congestion.
