In a Cisco SD-WAN architecture, what is the role of the WAN Edge?

  1. It provides orchestration to assist automatic provisioning of WAN Edge routers and overlay
  2. It is the management plane responsible for centralized configuration and monitoring
  3. It is the control plane that builds and maintains network topology
  4. It is the data plane that is responsible for forwarding traffic

Answer(s): D

Which TCP Optimization feature is used by WAN Edge to prevent unnecessary retransmissions and large initial TCP window sizes to maximize throughput and achieve a better quality?

  1. SACK
  2. SEQ
  3. RTT
  4. SYN

Answer(s): A

A network administrator is configuring VRRP to avoid a traffic black hole when the transport side of the network is down on the primary device. What must be configured to get the fastest failover to standby?

  1. OMP tracking
  2. higher group ID number
  3. prefix-list tracking
  4. lower timer interval

Answer(s): C



A network administrator is tasked to make sure that an OMP peer session is closed after missing three consecutive keepalive messages in 3 minutes. Additionally, route updates must be sent every minute. If a WAN Edge router becomes unavailable, the peer must use last known information to forward packets for 12 hours.

Which set of configuration commands accomplishes this task?





Answer(s): D

function of appnav in sdwan

  • AppNav (Application Navigation) is the Cisco SD-WAN feature that provides application-level visibility and control.
  • It maintains a catalog of applications (AppIDs) with attributes (ports/protocols, categories) and classifies traffic accordingly.
  • It allows policy authors to reference apps by name in policies, enabling application-aware routing, QoS, and service chaining based on the app’s requirements.
  • The SD-WAN fabric uses AppNav data to steer traffic along the best path, improving user experience for critical apps while optimizing WAN usage.
