Cisco CCNA certification explained
The CCNA, which stands for Cisco Certified Network Associate, is Cisco's foundational certification for networking professionals.
The CCNA is a commonly required prerequisite for associate-level networking jobs such as network engineer, network administrator, network support technician or help desk technician. There used to be 10 CCNA concentrations, specific to cloud, collaboration, security, data centers, wireless, and other areas. Then, in February of 2020, Cisco combined all of its foundational networking certifications into one comprehensive CCNA certification.
