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.<\/p>\n

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.<\/p>\n

CCNA training learning objectives<\/strong><\/h3>\n

This program will allow you to:<\/p>\n

    \n
  1. Understanding the fundamental principles of computer networks<\/strong> Learn how data travels through different communication media, the types of transmission (unicast, multicast, broadcast) and the protocols used.<\/li>\n
  2. Identify the essential components of a network<\/strong> : Discover the role of equipment such as switches, routers, firewalls, servers, Wi-Fi access points, etc., and their contribution to the overall infrastructure.<\/li>\n
  3. Differentiate between network types and their topologies<\/strong> Learn to distinguish between LAN, WAN, MAN, and WLAN networks, and understand client-server, peer-to-peer, and hybrid cloud environments.<\/li>\n
  4. Mastering OSI and TCP\/IP network communication models<\/strong> : 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.).<\/li>\n
  5. Implement network configurations through hands-on labs<\/strong> : Using Packet Tracer and simulated Cisco equipment, you will learn how to configure routers, switches, create VLANs, set up ACLs, and more.<\/li>\n
  6. Manipulating IP addresses and subnetting<\/strong> You will understand IP address classes, subnet masks, CIDR, and will know how to create an addressing plan suitable for any type of network.<\/li>\n
  7. Delve deeper into layer 3 and 4 protocols and services<\/strong> : Study in detail TCP, UDP, as well as application layer services such as DNS, DHCP, HTTP\/HTTPS, and their configuration in a network environment.<\/li>\n
  8. Initiate a discussion on network security and troubleshooting tools<\/strong> Learn to identify common threats, secure network access, and use tools such as Ping, Traceroute, or Wireshark to diagnose problems.<\/li>\n<\/ol>\n
