What is CCNA certification?

CCNA (Certified Cisco Networking Associate) is an Information Technology (IT) certification offered by Cisco System, a popular tech company based in the US and working internationally. Cisco is famously known as a global manufacturer and vendor of networking hardware such as switches, routers, wireless devices, and other high-tech equipment. They also provide non-networking related products like security systems, video conferencing systems and cloud computing systems to name a few.

The CCNA R&S opens up numerous possibilities for networking professionals in their career as well as in terms of knowledge and skill set. Cisco also holds a huge share of the networking market and numerous corporates use their products and services. This is why candidates who are well versed in using Cisco’s technology will always be preferred by employers over non-certificate holders.

Cisco also offers professional certifications in Cisco products at five levels- Entry level, Associate level, Professional level, Expert level and finally Architect level.

The CCNA is a foundation level certification, one level above the CCENT (Cisco Certified Entry Networking Technician) and below the CCNP (Cisco Certified Networking Professional).

The CCNA Certification validates a candidate’s abilities to install, operating and troubleshooting a small or medium-sized networking system. In keeping with the evolution of the tech industry and the newly emerging job roles, Cisco provides the Associate level certifications in nine subspecialties namely:

  1. Routing and Switching
  2. Security
  3. Service Provider
  4. Collaboration
  5. Cloud
  6. Data Centre
  7. Industrial
  8. Wireless
  9. Cyber Ops
