## Scenario: [v1-S7] Network Interface Configuration
|
|
|
|
### Original Problem
|
|
From Practice Scenarios v1, Scenario 7:
|
|
1. Configure static IPv4 address: 192.168.1.100/24
|
|
2. Configure static IPv6 address: 2001:db8:1234:5678::100/64
|
|
3. Set hostname to 'rhcsa.example.com'
|
|
4. Configure DNS resolution using /etc/resolv.conf
|
|
5. Implement network access restrictions using firewalld zones
|
|
|
|
### Environment
|
|
- OS Version: RHEL/Rocky Linux 8.x
|
|
- Initial State: DHCP-configured network interface
|
|
- Required Outcome: Properly configured static network settings with hostname and firewall zones
|
|
|
|
### Solution Steps
|
|
1. Check Current Network Configuration
|
|
```bash
|
|
# Check network interfaces
|
|
ip addr show
|
|
|
|
# Check routing
|
|
ip route show
|
|
```
|
|
