CCNA Switching, Routing and Wireless Essentials we teach you to configure and troubleshoot routers and switches in small-to-medium networks, build and secure wireless LANs (WLANs), and understand core network security concepts. This course is the second in a three-part series and provides the practical skills needed for roles like Network Administrator or Engineer, and prepares you for the CCNA certification exam.

• Switching:
  • Configure initial switch settings, switch ports, and secure remote access.
  • Understand and configure VLANs, VLAN trunks, and dynamic trunking protocols.
  • Configure and troubleshoot switch redundancy using protocols like STP and EtherChannel.
• Routing:
  • Configure and troubleshoot routers for advanced functionality.
  • Perform and troubleshoot inter-VLAN routing using methods like "router-on-a-stick" and Layer 3 switches.
  • Verify directly connected and dynamic routing protocols.
• Wireless:
  • Understand the architecture and operation of wireless local area networks (WLANs).
  • Configure and secure a basic WLAN, including wireless security protocols like WPA2-PSK.
• Security:
  • Implement and verify Layer 2 security features, such as DHCP snooping, dynamic ARP inspection, and port security.
  • Configure and verify access control lists (ACLs).
  • Secure remote access to network devices.
  • Define key security concepts, including threats, vulnerabilities, and mitigation techniques.
• Troubleshooting:
  • Use tools like Cisco Packet Tracer to develop critical thinking and problem-solving skills.
  • Troubleshoot common issues in both IPv4 and IPv6 networks.
  • Resolve problems related to switch ports, speed, and duplex settings.
• Other essentials:
  • Learn how to support reliable networks using dynamic addressing and first-hop redundancy protocols.
  • Understand the role of intelligent and sustainable networking practices.
