Your teacher or a partner breaks one thing on a working lab network. Find and fix each fault using the method above and write a ticket for each:
- Wrong subnet mask on a PC.
- Wrong default gateway.
- DNS server address typed incorrectly.
- Web service stopped on the server.
- Firewall rule blocking port 80.
- Disconnected or wrong-VLAN port.
- Disk full or stopped service on a Linux server.
Use the method: follow the "cannot reach the Internet" sequence for each fault and record it in a ticket like the sample in 9.7.
