The digital world today relies on complex and interconnected network infrastructures. Whether accessing a web page, sending an email, or using cloud services, computer networks are ubiquitous. This is why networking skills have become essential in IT, cybersecurity, cloud computing, and IT infrastructure professions.
The CCNA (Cisco Certified Network Associate) training is a globally recognized certification that allows you to gain an in-depth understanding of how computer networks work, from their architecture to their administration. This course is suitable for both beginners and professionals seeking a career change who want to build a solid technical foundation.
CCNA training learning objectives
This program will allow you to:
- Understanding the fundamental principles of computer networks Learn how data travels through different communication media, the types of transmission (unicast, multicast, broadcast) and the protocols used.
- Identify the essential components of a network : Discover the role of equipment such as switches, routers, firewalls, servers, Wi-Fi access points, etc., and their contribution to the overall infrastructure.
- Differentiate between network types and their topologies Learn to distinguish between LAN, WAN, MAN, and WLAN networks, and understand client-server, peer-to-peer, and hybrid cloud environments.
- Mastering OSI and TCP/IP network communication models : Each layer of the model (physical, data link, network, transport, session, presentation, application) will be analyzed, with the corresponding protocols (Ethernet, IP, TCP, UDP, HTTP, etc.).
- Implement network configurations through hands-on labs : Using Packet Tracer and simulated Cisco equipment, you will learn how to configure routers, switches, create VLANs, set up ACLs, and more.
- Manipulating IP addresses and subnetting You will understand IP address classes, subnet masks, CIDR, and will know how to create an addressing plan suitable for any type of network.
- Delve deeper into layer 3 and 4 protocols and services : Study in detail TCP, UDP, as well as application layer services such as DNS, DHCP, HTTP/HTTPS, and their configuration in a network environment.
- Initiate a discussion on network security and troubleshooting tools Learn to identify common threats, secure network access, and use tools such as Ping, Traceroute, or Wireshark to diagnose problems.
