Match each Linux DHCP artifact or tool to its corresponding role: Items: 1. /etc/dhcp/dhcpd.conf 2. /var/lib/dhcpd/dhcpd.leases 3. journalctl -u dhcpd 4. dhcp-server Roles: A. Main configuration file defining subnets and daemon parameters B. Database file recording active client address assignments C. Command used to view DHCP service logs D. Package installed via dnf to provide the DHCP server daemon

Each item has a distinct role in the Linux DHCP workflow. `/etc/dhcp/dhcpd.conf` contains configuration, and `/var/lib/dhcpd/dhcpd.leases` holds lease records that can help verify client assignments. `journalctl -u dhcpd` is a way to inspect logs for the DHCP service, while `dhcp-server` is the package installed with `dnf`. Confusing these artifacts can waste troubleshooting time—for example, lease records will not reveal a typo in the main configuration as directly as configuration review and service logs. **Key takeaway:** Identify whether you need configuration, lease state, package management, or service logs before choosing a file or command.\n\n**Glossary:** **Lease record**: Stored information about an address assignment.
