LFCS Networking Practice Question
A network interface eth0 is not receiving an IP address via DHCP. Which command can be used to troubleshoot the DHCP client process?
⚠ Common exam trap
Candidates often confuse the DHCP client process (dhclient) with the DHCP server process (dhcpd), leading candidates to choose options that manage or test the server instead of the client.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
dhclient -v eth0
The `dhclient -v eth0` command runs the DHCP client in verbose mode on interface eth0, which is the correct tool to troubleshoot the DHCP client process. It shows detailed messages about the DHCPDISCOVER, DHCPOFFER, DHCPREQUEST, and DHCPACK exchange, helping identify where the process fails. This directly addresses the issue of the interface not receiving an IP address via DHCP.
