Which steps or checks are appropriate when troubleshooting a Linux DHCP deployment described in the course? Select ALL that apply.

The first four actions examine distinct parts of a Linux DHCP deployment: configuration, service logs, firewall access, and recorded leases. Each can help locate a different class of problem. A malformed configuration may prevent startup; logs may report service errors; a firewall may block DHCP communication; and the lease file can show whether assignments have been recorded. The final option is incorrect because the material identifies `dhcpd` as the Linux DHCP service. **Key takeaway:** Troubleshoot configuration, service operation, network access, and lease records as separate but connected layers.\n\n**Glossary:** **Firewall**: A network traffic control mechanism that may allow or block DHCP communication.
