JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2021) — Question 93

You are implementing an SRX Series device at a branch office that has low bandwidth and also uses a cloud-based VoIP solution with an outbound policy that permits all traffic.
Which service would you implement at your edge device to prioritize VoIP traffic in this scenario?

Answer options

Correct answer: D

Explanation

The correct answer is D, AppQoS, as it is specifically designed to manage and prioritize application traffic, ensuring VoIP traffic receives the necessary bandwidth. AppFW is focused on application-level firewalls, SIP ALG deals with SIP traffic specifically but does not prioritize it, and AppQoE is geared toward enhancing application performance rather than traffic prioritization.
