Why study this course

The Designing Cisco Enterprise Networks (ENSLD) v1.0 course gives you the knowledge, skills and best practices you need to design an enterprise network.

This course serves as a deep dive into enterprise network design and expands on the topics covered in the Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) course. Topics include advanced addressing and routing solutions, advanced enterprise campus networks, WAN, security services, network services, and software-defined access SDA.

This course also helps you prepare to take the exam 300-420 (ENSLD), which is part of the CCNP Enterprise and Cisco Certified Specialist – Enterprise Design certifications.

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.
