SD-WAN is a software-defined approach to managing the WAN that offers several capabilities, such as:
The separation of management plane, control plane and data plane to enable horizontal scaling. This means that the SD-WAN solution can decouple the network functions from the underlying hardware and distribute them across different layers and locations. This allows for greater flexibility, scalability, and resilience of the network12
Cloud hosted or on-premise fully redundant management and control plane functions. This means that the SD-WAN solution can provide centralized and cloud-based management and control of the network, as well as the option to deploy them on-premise for more control and security. This enables the SD-WAN solution to offer consistent policies, visibility, and analytics across the network, as well as the ability to automate network operations and orchestration13
The other options are not SD-WAN solution capabilities, but rather features or benefits of specific SD-WAN solutions, such as:
Trust roll branch turn up for easy provisioning and new installations. This is a feature of Cisco Catalyst SD-WAN, which enables zero-touch provisioning and automated configuration of branch devices, as well as the ability to trust the identity and security posture of the devices3
Ability to provide and integrate security with complementary products and applications. This is a benefit of Cisco Catalyst SD-WAN, which offers integrated security capabilities, such as full-stack multilayer security, cloud-delivered security, and SASE-enabled architecture. This enables the SD-WAN solution to provide real-time threat protection and compliance across the network3
