Explanation Explanation: IP SLA uses active traffic monitoring, which generates traffic in a continuous, reliable, and predictable manner to measure network performance. IP SLA sends data across the network to measure performance between multiple network locations or across multiple network paths. It simulates network data and IP services, and collects network performance information in real time. This information is collected: ✑ Response times ✑ One-way latency, jitter (interpacket delay variance) ✑ Packet loss ✑ Network resource availability LLQ uses the priority command. The priority command allows you to set up classes based on a variety of criteria (not just User Datagram Ports (UDP) ports) and assign priority to them, and is available for use on serial interfaces and ATM permanent virtual circuits (PVCs). A similar command, the ip rtp priority command, allows you to stipulate priority flows based only on UDP port numbers. Note: All the other answer choices can be used to improve TCP performance, but not UDP.
