Explanation

Application-aware routing (AAR) configurations are central to SD-WAN policy because SD-WAN's core value proposition is steering traffic based on application identity and real-time path performance - AAR policies define how applications map to SLAs and which WAN transport paths they should use, making them the primary target when diagnosing policy misbehavior.

Why the distractors are wrong:

  • A (VPN tunnel status) - Tunnel health is a connectivity concern, not a policy concern; tunnels can be up while policy is misconfigured.
  • B (User permissions) - SD-WAN policy operates at the network/transport layer and is not governed by user-level permissions.
  • D (OSPF cost metrics) - SD-WAN uses its own overlay routing and SLA metrics, not traditional OSPF cost; OSPF may exist in the underlay but is not where SD-WAN policy decisions live.

Memory tip: Think "SD-WAN = Application DNA" - the whole point of SD-WAN over traditional WAN is application awareness, so when something goes wrong with policy, you always start with AAR configs.
