Why study this course

The Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) v1.2 course gives you the knowledge and skills needed to configure, troubleshoot, and manage enterprise wired and wireless networks. You’ll also learn to implement security principles within an enterprise network and how to overlay network design by using solutions such as SD-Access and SD-WAN.

The course includes additional self-study material that can be done at your own pace after the instructor-led portion of the course.

This course, including the self-paced material, helps you prepare to take the 350-401 (ENCOR) exam, which is part of four certifications:

  • CCNP Enterprise

  • CCIE Enterprise Infrastructure

  • CCIE Enterprise Wireless

  • Cisco Certified Specialist – Enterprise Core

Digital courseware: Cisco provides students with electronic courseware for this course. Students who have a confirmed booking will be sent an email prior to the course start date, with a link to create an account via before they attend their first day of class. Please note that any electronic courseware or labs will not be available (visible) until the first day of the class.
