CCNA (Cisco Certified Network Associate)
The Cisco Certified Network Associate (CCNA) is a globally recognized IT certification offered by Cisco Systems. It is designed for individuals looking to build foundational knowledge and skills in networking and to kickstart a career in the field of computer networking and IT infrastructure.
The CCNA certification provides a solid understanding of networking concepts, including how networks operate, how to install, configure, and troubleshoot routers and switches, and how to implement basic network security. It also introduces key concepts related to IP addressing, subnetting, routing protocols (like OSPF and EIGRP), VLANs, access control lists (ACLs), network automation, and wireless networking.
The current CCNA (200-301) exam covers a wide range of topics including:
1.Network Fundamentals
2.IP Connectivity and IP Services
3..Security Fundamentals
4.Automation and Programmability
5.LAN/WAN Technologies
6.Routing and Switching
CCNA is ideal for aspiring network engineers, support engineers, and system administrators. Earning this certification not only improves technical knowledge but also increases job opportunities and salary potential in the IT industry.
Whether you are a beginner or transitioning into networking from another IT field, CCNA offers the skills necessary to understand and manage modern network environments.
