Which of the following can be used to assign priority to specific network traffic?

Load balancing distributes network or application traffic across multiple servers or links to improve capacity and reliability, but it does not assign priority to specific traffic types.

QoS uses traffic classification, marking (DSCP, CoS), and queuing policies to prioritize specific traffic types such as VoIP or video over lower-priority data. Network devices inspect packet markings and place traffic into priority queues, guaranteeing bandwidth and reducing latency for critical applications. This is the standard mechanism for traffic prioritization across enterprise and service-provider networks.

NIC teaming combines multiple physical network adapters into a logical interface for increased throughput and fault tolerance, but it provides no mechanism for prioritizing one traffic type over another.

Jumbo frames increase the Maximum Transmission Unit (MTU) beyond the standard 1500 bytes to improve throughput for large data transfers, but they do not influence traffic priority or queuing.
