What is CCNA?

CCNA (Cisco Certified Network Associate) is an entry-level IT certification offered by Cisco. It validates the ability to install, configure, operate, and troubleshoot medium-sized routed and switched networks, including implementation and verification of connections to remote sites in a WAN. CCNA also covers basic security threats and mitigation, wireless networking fundamentals, and an understanding of network automation and programmability. It is commonly used to demonstrate foundational networking knowledge for entry-level network engineering or technician roles.
