Which programming protocols are used for Cisco SD-WAN Programmability?

The correct choice highlights the protocols that are specifically designed for network automation and programmability in a Cisco SD-WAN environment. NETCONF and REST APIs are pivotal in this context because they allow for more dynamic and flexible configurations, facilitating the management of network devices through programmatic interfaces.

NETCONF is a network management protocol that leverages XML to provide a standardized mechanism for configuring and monitoring network devices. It allows for transactional operations, meaning it can apply changes, retrieve data, and ensure that modifications do not result in inconsistent configurations.

REST APIs, on the other hand, utilize standard web protocols to enable communication with network devices, making it easier to integrate with various applications and services. They allow developers to interact with Cisco SD-WAN orchestrators in a straightforward and modern way, catering to the growing trend of software-defined networking and service integration through web technologies.

These protocols together aid in automating tasks, enhancing scalability, and facilitating real-time management of network resources in an SD-WAN setup, ultimately leading to improved efficiency and responsiveness in network operations.
