Juniper Mist WAN Assurance provides AI-driven operations for SD-WAN environments, focusing on delivering better user experiences for branch and WAN users. The primary hardware platforms that are onboarded and managed by Mist for this solution are the SRX Series Services Gateways, which provide secure SD-WAN capabilities, and the Juniper Session Smart Routers (SSR), which offer a tunnel-free, session-based routing architecture. Both platforms serve as the SD-WAN edge devices for the branch.

B. EX Series Switches are Ethernet switches used for campus and branch access layers. They are managed under Juniper Mist Wired Assurance, not WAN Assurance.

D. QFX Series Switches are high-performance data center switches. They are not part of the WAN Assurance solution.
