CCNA Certification details are available in this article. CCNA stands for Cisco Certified Network Assiocate is an Information Technology certification from CISCO.CCNA Certification is an associate-level Cisco Career Certification. Cisco created the CCNA to recognize basic competency in installation and support of medium-sized networks.

The Cisco Certified Network Associate (CCNA) Certification is the second level of Cisco’s five-level career certification process. A CCNA certification certifies a technician’s ability to install, set up, configure, troubleshoot and operate a medium-sized routed and switched computer network. This also includes implementing and verifying connections to a wide area network (WAN).

Types of CCNA Certifications

Cisco expanded the program to cover many other facets of computer networking and network administration, offering certifications at five increasingly demanding levels:

• Entry, Associate,
• Professional, Expert, and

Currently, the CCNA Specialized Certifications are listed below ,Please have a look over it

• CCNA Cloud
• CCNA Collaboration
• CCNA Cyber Ops
• CCNA Data Center
• CCNA Industrial
• CCNA Routing and Switching
• CCNA Security
• CCNA Service Provider
• CCNA Wireless

The CCNA Certification validates a firm foundation of networking skills that include fundamentals like the OSI Reference Model, Networking Protocols, Layer 2 Switching Concepts and Protocols, Routing Concepts and Protocols, and Wide-Area Networking (WAN) Connectivity. Thus a person who is aiming to qualify for the CCNA certification should be proficient in their abilities to provide basic network installations and troubleshooting.

CCNA Routing and Switching, has served as the most important starting point in the Cisco certification world for decades.There are no prerequisites for the entry level certification.

To achieve CCNA certification one must pass either

• The ICND1 Exam(100-105) and the ICND2 Exam(200-105)
• The Combined CCNA Exam(200-125)

CCENT Cisco Certified Entry Network Technician is the entry level exam to get the CCNA Certification later .
