Service Design

SD-WAN can provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud across any type of IP-based underlay transport network. Which two statements describe SD-WAN solutions?

Choose two
  • A Control and data forwarding planes are kept separate.
  • B Solutions allow for variations of commodity and specialized switching hardware.
  • C SD-WAN networks are inherently protected against slow performance.
  • D Solutions include centralized orchestration, control, and zero-touch provisioning.
  • E Improved operational efficiencies result in cost savings.
Explanation

SD-WAN architectures separate control-plane decisions from data-plane packet forwarding, allowing centralized controllers to distribute policy and routing information independently of forwarding devices. They also use centralized management and orchestration to automate site onboarding and configuration, including zero-touch provisioning. Cisco documents the separation of control and data planes and centralized controllers that manage provisioning across the overlay network.
