Video description

This course is an intensive path to CompTIA Network+ certification, offering a complete dive into essential networking skills. Begin with foundational topics like network types, classifications, and topologies, then move into the OSI model and core protocols crucial for network design and management. Hands-on sessions deepen your understanding of Ethernet, MAC addressing, routers, and VLANs, helping you to develop practical, ready-to-use skills.

As you progress, the course explores IP addressing (IPv4 and IPv6), subnetting, and routing, providing clarity on these often challenging areas. You'll also cover security essentials, including network hardening, access control, and encryption, preparing you for real-world scenarios involving common attacks like DoS and VLAN hopping. This in-depth security training ensures you're ready to identify and mitigate potential threats effectively.

The course concludes with advanced topics in troubleshooting, monitoring, and disaster recovery, plus a focus on cloud technologies like NFV and VPCs. With exam preparation strategies and practical exercises, you'll finish with the confidence and skill set needed for the CompTIA Network+ exam and to succeed in your networking career.

What you will learn

  • Explain OSI model layers and key network protocols effectively
  • Configure and manage network devices, VLANs, and topologies
  • Differentiate IPv4 and IPv6 addressing and perform subnetting
  • Apply secure network practices and implement access controls
  • Troubleshoot network performance and connectivity issues
  • Prepare confidently for the CompTIA Network+ certification exam

Audience

This course is designed for aspiring network administrators, IT support technicians, and anyone pursuing the CompTIA Network+ certification. Prior foundational knowledge in basic computer operations and network concepts is recommended but not required, as the course begins with fundamentals before advancing to complex topics.
