The CCNA certification covers a broad range of networking topics and validates the following skills:
Network Fundamentals: Understanding basic networking concepts and technologies.
Network Access: Configuring and managing network devices, such as routers and switches.
IP Connectivity: Understanding and configuring IP addressing, subnetting, and routing.
IP Services: Configuring network services, including DHCP, NAT, and ACLs.
Security Fundamentals: Implementing basic network security measures.
Automation and Programmability: Introduction to network automation and programmability using tools like Python and REST APIs.
The CCNA certification underwent a significant update in 2020, consolidating various CCNA tracks into a single, comprehensive certification. This update ensures that CCNA holders have a well-rounded understanding of networking technologies.
To earn the CCNA certification, candidates need to pass one exam, which covers the above topics. Cisco provides official training materials, including books and online courses, to help candidates prepare for the exam. There are also many authorized Cisco Learning Partners that offer instructor-led training for the CCNA. As certification details can change, it’s recommended to check the official Cisco website for the most up-to-date information on the CCNA certification program.
