Description

Network Programmability for the Data Center (NPDC) v1.0 is a four-day instructor led course. This course teaches how to automate an end-to-end Cisco Data Center consisting of Nexus 7000 and 9000 switches. This course also includes Cisco ACI and UCS platforms using state of the art Model Driven API�s. 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.

Objectives

Upon completing this course, the learner will be able to meet these overall objectives:
