During a large public event, municipal networks experience congestion while emergency voice and video must stay usable for first responders. How does QoS support resilience here?
Select an answer to reveal the explanation.
Short Explanation
When the network is jammed, QoS is the express lane for 911-grade voice and video. Backups can wait; responders cannot.
Full Explanation
Quality of Service mechanisms mark and prioritize traffic so latency-sensitive emergency voice and video retain capacity during congestion or flood-style load. That resilience function complements HA and recovery-site planning for critical communications. Deprioritizing emergency traffic or treating QoS as merely billing undermines public-safety operations. QoS does not eliminate the need for diverse paths, but it protects service quality on contested links.
