How to prepare for Cisco DNA
Cisco Digital Network Architecture (DNA) is an open extensible software-driven architecture that simplifies enterprise network operations. It is part of an SDN approach that includes SD-WAN, SD-Access, intent-based networks as well as existing traditional networks.
Cisco DNA is included in some of the Cisco certification exams as a topic. Unfortunately, DNA is a difficult thing to emulate, and in most cases you need to have the real thing to practice with it. But keep in mind that Cisco knows that, so it’s not necessarily obligatory to have hands-on experience to obtain the certifications.
