Lab Question 1: What are the key components of a network infrastructure?

Answer: A network infrastructure consists of various components, including:

  • Switches: These devices connect network devices and facilitate data transmission within a Local Area Network (LAN).
  • Routers: Routers are responsible for connecting different networks and enabling communication between them.
  • Firewalls: These security devices protect networks from unauthorized access and ensure data integrity.
  • Network Cables: These cables are used to establish physical connections between devices.
  • Network Protocols: Protocols like TCP/IP enable network communication and ensure data routing.

Lab Question 2: How can you troubleshoot a network connectivity issue?

Answer: Network connectivity issues can be diagnosed and resolved through the following steps:

  1. Check physical connections: Ensure all cables are securely connected, and devices have power.
  2. Verify IP configurations: Check if devices have valid IP addresses and are on the correct subnet.
  3. Test connectivity with loopback addresses: Use loopback addresses to verify if network interfaces are functioning correctly.
  4. Use network diagnostic tools: Tools like ping, traceroute, and Wireshark can help identify and analyze network issues.
  5. Inspect network device configurations: Check device settings, routing tables, and access control lists for any misconfigurations.
  6. Replace faulty hardware or cables: If all else fails, faulty hardware or cables might be the cause, requiring replacement.

These are just a few examples of the CCNA lab questions covered in our comprehensive guide. By practicing these questions,
you will strengthen your understanding of networking concepts and be better prepared for the CCNA exam.

Remember, hands-on practice in real or simulated lab environments is crucial for gaining practical knowledge and confidence
in network administration. The CCNA certification is highly valued in the industry and can open doors to exciting career
opportunities.
