What is CCNA?
CCNA (Cisco Certified Network Associate) is a category of technical certifications offered by Cisco for early-career networking professionals. The CCNA is the second level of accreditation, one step above Cisco Certified Entry Networking Technician (CCENT) and directly below the CCNP (Cisco Certified Network Professional).
