Which Cisco SD-WAN capability allows centralized management of application-aware QoS policies?

• A. Native VLAN mapping
• B. STP root balancing
• C. VTP synchronization
• D. Centralized policy framework

Answer: (D)

The capability being tested is a centralized policy framework. In Cisco SD-WAN, you define application-aware QoS policies once in a central controller and push them out to all edge devices. This lets the network recognize different applications, assign appropriate classes of service, and apply priorities, bandwidth limits, or shaping rules consistently across the entire WAN. Because policies are managed centrally, changes propagate automatically, giving you uniform QoS behavior at every site and simplifying management compared with configuring QoS separately at each device.

The other options don’t address centralized QoS policy management in SD-WAN. Native VLAN mapping deals with mapping VLAN IDs at Layer 2, STP root balancing concerns spanning-tree root selection, and VTP synchronization handles VLAN database distribution among switches. None of these provide application-aware QoS policy management across the network.
