I'll choose these: Centralized distribution of policies throughout the network. Operates over DTLS/TLS authenticated and secured tunnels. Provides flexibility and scalability through a hub and spoke architecture.

given answer is incorrect Cisco SD-WAN Characteristics: - centralized distribution of policies throughout the network - operates over DTLS/TLS authenticated and secured tunnels - provides flexibility and scalability through a hub and spoke architecture

I think answer is : 1. Uses unique per device feature templates 2. Centralized distribution of policies throughout the network. 3. Operates over DTLS/TLS authenticated and secured tunnels.

Uses unique per device feature templates: This is true. Cisco SD-WAN allows for the creation of feature templates that define the configuration for different device types, streamlining the process. Centralized distribution of policies throughout the network: Cisco SD-WAN is known for centralized policy management, which means policies are distributed from a central controller to the entire network. Operates over DTLS/TLS authenticated and secured tunnels: Cisco SD-WAN secures data transport over the network using encrypted tunnels, typically DTLS or TLS.

IMO: -Centralized distribution of policies throughout the network. -Operates over DTLS/TLS authenticated and secured tunnels. -Control plane connections between routers Default behavior is full mesh: "In a Cisco SD-WAN network, vEdge routers build a full-mesh topology with vEdge routers in other sites. This is the default behavior, and it means that all devices within a service VPN can communicate with each other." "Control plane connections: Each Cisco SD-WAN Controller establishes and maintains a control plane connection with each edge router in the overlay network" - https://networklessons.com/cisco/cisco-sd-wan/cisco-sd-wan-hub-and-spoke-topology#:~:text=In%20a%20Cisco%20SD%2DWAN,can%20communicate%20with%20each%20other. -https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/sdwan-xe-gs-book/system-overview.html#:~:text=The%20major%20components%20of%20the,router%20in%20the%20overlay%20network.
