Cisco made significant changes to its exam structure on Feb. 24, 2020, putting a focus on simplifying it and making it more flexible. It also attempted to align the exam more closely with modern industry needs. The latest update consolidated those offerings into one CCNA certification, which is now the foundational certification for all Cisco-based career paths.
