Question

A network engineer is configuring a Cisco Catalyst SD-WAN application-aware routing (AAR) policy for a company's north/south traffic toward a critical cloud-hosted ERP application. The requirement states that ERP traffic must only use transport tunnels that meet a maximum of 2% packet loss and 150 ms latency; if no tunnel meets the SLA, traffic should still be forwarded rather than dropped. Which combination of AAR policy elements achieves this behavior?

Accepted Answer

Define an SLA class with loss 2% and latency 150 ms, apply it to the ERP sequence, and enable the 'backup-sla-preferred-color' or default fallback so traffic still forwards when no tunnel meets the SLA

Answer

Define an SLA class with loss 2% and latency 150 ms and configure a strict SLA action so traffic is dropped when no tunnel qualifies

Answer

Apply a centralized control policy with TLOC lists instead of an SLA class, since AAR cannot measure loss and latency

Answer

Configure a data policy with a set local-tloc-list action referencing the ERP prefix, which enforces loss and latency thresholds automatically
