Cisco Certified Network Associate (200-125)

The Cisco Certified Network Associate (CCNA) Routing and Switching composite exam (200-125) is a 90-minute, 60–70 question assessment that is associated with the CCNA Routing and Switching certification. This exam tests a candidate’s knowledge and skills related to network fundamentals, LAN switching technologies, IPv4 and IPv6 routing technologies, WAN technologies, infrastructure services, infrastructure security, and infrastructure management.
