A healthcare provider is planning a Prisma SD-WAN rollout across 80 clinics. Each clinic has two broadband circuits from different ISPs and a requirement that telehealth video traffic maintain latency below 100 ms and jitter below 30 ms. The design must automatically steer telehealth traffic to the best-performing circuit and fail over if thresholds are breached. Which Prisma SD-WAN design element is required?
Prisma SD-WAN policies can classify telehealth traffic and select paths based on real-time performance metrics such as latency and jitter. If thresholds are breached, the policy automatically steers traffic to a better circuit. This directly satisfies the requirement for automatic best-path selection and failover for telehealth video across 80 clinics with dual broadband.
Why this answer
Performance-based path selection policies are the Prisma SD-WAN mechanism that monitors latency and jitter and steers traffic to the best circuit. By applying such a policy to the telehealth application, the design ensures automatic best-path selection and failover when thresholds are breached. Static routes, BGP timers, and ECMP cannot react to application-level performance, so they do not satisfy the requirement.
Exam trap
The trap here is confusing link-state failover with performance-based steering, when SD-WAN policies must evaluate latency and jitter to meet application SLAs.
