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.
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.
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
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"

Disregard ^^^^
reading further into the Network Lessons link "a full mesh topology is not always required, and with many vEdge routers, it can even become a scalability issue. This lesson will explain how you can use a centralized policy to configure a hub and spoke topology."
The answers below mine appear correct:
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.
but the hub and spoke architecture is an option, you can deploy using fulll-mesh, the idea of SD-WAN is been flexible always
