Juniper JNCIS-SEC JN0-335 Question # 11 Topic 2 Discussion

AppQoS is a service that allows you to prioritize and manage the quality of service (QoS) for different types of applications on SRX Series devices. AppQoS uses application signatures to identify and classify the traffic, and then applies QoS policies to assign bandwidth, priority, and scheduling parameters to the traffic. AppQoS can help you optimize the performance of critical applications, such as VoIP, and ensure that they get the required bandwidth and latency in a congested network12. In this scenario, you can use AppQoS to prioritize the VoIP traffic over other traffic and guarantee its QoS on the SRX Series device at the branch office. References:
