Cisco’s networking certifications are highly regarded in the IT industry and provide professionals with a pathway to specialize and advance in their careers. Whether you’re looking to break into networking or elevate your current career, understanding what the CCNA certification entails, its significance, and how it fits into the broader Cisco certification structure will give you a strong foundation for making informed decisions about your career path.
Evolution of the CCNA Certification
Historically, Cisco offered a wide variety of certifications that targeted specific networking skills and technologies. These included certifications for routing, switching, security, and more. For many years, Cisco Certified Network Associates (CCNA) certifications were broken down into specialized areas such as CCNA Routing & Switching, CCNA Security, CCNA Wireless, and others, each focusing on particular networking concepts and technologies.
However, in November 2023, Cisco made a significant shift in its certification model. The traditional specialization approach, which had grown to include up to ten different CCNA exams, was consolidated into a more unified structure, simplifying the path for certification candidates. This was done to align better with modern network environments and the evolving needs of IT professionals.
This new certification structure divides Cisco certifications into five levels, starting from the most basic and moving toward expert-level qualifications. These levels are:
- Entry: Targeted at beginners or those new to the IT and networking fields.
- Associate: Designed for professionals who are looking to expand their knowledge and skills in network administration, engineering, and other foundational networking roles.
- Professional: Intended for experienced network professionals who want to specialize in more advanced and complex networking topics.
- Expert: For those who have a deep, specialized understanding of networking systems and infrastructure.
- Architect: The highest level, representing the ability to design and architect complex networks and systems.
The Associate level, which includes the CCNA certification, is now the primary certification at this level, replacing multiple specialized CCNA exams. This new structure allows professionals to focus on broader networking concepts, enabling them to adapt to various networking environments.
The Structure of Cisco’s Certification Tiers
Each of the five certification levels comes with a variety of exams that cater to different areas of specialization and professional experience.
