Cisco is a giant in IT Networking Industry which has its products distributed in every corner of the world. Cisco introduced its Certifications to provide the skills and techniques to Network Engineers to configure, support and troubleshoot these products in its organizations.

These certifications are one of the most prestigious IT certifications known.

The Certifications are divided into various domains into 3 major levels.

  1. CCNA
  2. CCNP
  3. CCIE

It is the higher level of Cisco Certification. Like CCNA, one learns to do the installation, configuration, and troubleshooting but on a much larger scale. CCNP Certification gives you the firm understanding of various networks, how they work together, their advanced security and video and wireless solutions. The troubleshooting skills of CCNP Certified are much on much higher level than of CCNA. CCNP Certified Networkers have profound knowledge and exposure.

The CCNA Certification can be done in

  1. Routing and Switching
  2. Service Provider
  3. Collaboration
  4. Data Centre
  5. Wireless
  6. Security
  7. Cloud
