Which is a QoS model that a network engineer would implement to ensure a source to destination quality of service standard for a specified data flow?
- integrated services
- differentiated services
- best effort
- class-based weighted fair queuing
- low latency queuing
| Answers Explanation & Hints:
Best effort is the default packet forwarding design and provides no QoS. The differentiated services model enforces and applies QoS mechanisms on a hop-by-hop basis, not source to destination. Class-based weighted fair queuing and low latency queuing are queuing algorithms. |
