LPIC-1 Essential System Services and Networking Practice Question
A DHCP server assigns IP addresses to clients, but some clients are not receiving the correct gateway. Which configuration file should be checked on the DHCP server?
⚠ Common exam trap
Watch out — candidates often confuse the DHCP server configuration file path with the older /etc/dhcpd.conf (option A) or mistakenly think the client configuration file (option B) controls server-side gateway assignment, when in fact the server's gateway is set via 'option routers' in /etc/dhcp/dhcpd.conf.

Correct answer & explanation
✓
/etc/dhcp/dhcpd.conf
The DHCP server configuration file on Linux systems is typically located at /etc/dhcp/dhcpd.conf (or /etc/dhcpd.conf on some older distributions). This file contains the subnet declarations, option definitions (such as option routers for the default gateway), and other parameters that the DHCP server uses to assign IP addresses and configuration details to clients. If clients are not receiving the correct gateway, the 'option routers' directive within this file should be checked and corrected.
