The fundamentals of CCNA (Cisco Certified Network Associate) networking cover a broad range of networking concepts and technologies. Here are some key fundamentals in brief:
Network Basics: Understanding the basics of networking, including the OSI (Open Systems Interconnection) and TCP/IP models, IP addressing, subnetting, and network topologies.
Switching: Learning about Ethernet switching, VLANs, trunking, spanning tree protocols (STP), and virtual LAN trunks (VTP).
Routing: Exploring routing protocols such as Routing Information Protocol (RIP), Enhanced Interior Gateway Routing Protocol (EIGRP), and Open Shortest Path First (OSPF). Understanding static routing and dynamic routing principles.
IP Addressing: Mastering IP addressing concepts, including IPv4 and IPv6 addressing, subnet masks, and subnetting techniques.
Network Services: Understanding common network services such as Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), Network Address Translation (NAT), and Network Time Protocol (NTP).
