Description

The Designing and Implementing Cisco Network Programmability (NPDESI) v1.0 is a 5-day instructor-led course that introduces learners to the evolving role of network engineers towards more programmability, automation and orchestration, enabling them to leverage the powerful level of abstraction provided by controller-based architectures to create real added value. The course provides knowledge and skills related to network programmability fundamentals, application programming interfaces (APIs) and automation protocols, data models, operations, and controllers.
The goal of this course is to provide learners with a foundation to get started with network programmability by learning how to minimize the amount of manual interactions (command-line interface [CLI]) with the network, and increase the use of scripts and automation tools to drive down operational inefficiencies. Within these goals, learners review network programmability fundamentals such as using Linux and Python, common automation protocols such as network configuration protocol (NETCONF) and representational state transfer (REST), how they relate to YANG data models, software-defined networking (SDN) controller northbound and southbound APIs, how to use device APIs on various Cisco platforms, and how to get started using automation tools such as Ansible and Puppet.

The course is aligned with the topics covered by the 300-550 NPDESI exam leading to the Cisco Network Programmability Design and Implementation Specialist certification.
