Network Programmability for the Enterprise (NPEN) v1.0 is a four-day instructor led course. This course teaches how to automate common Cisco enterprise platforms such as IOS-XE and IOS-XR routers as well as ASA firewalls. This course also includes coverage of the automation capabilities of the APIC Enterprise Module or “APIC-EM”. Applying CCIE-style learning methods, the course places emphasis on learning via hands-on labs and hands-on demonstrations. The terms “proof-by-Python” and “proof-by-JSON or XML” will be used frequently throughout the course.
