LPIC-2 Network Client Management Practice Question
This LPIC-2 practice question tests your understanding of network client management. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
What is the recommended way to configure a Linux host to obtain an IP address automatically via DHCP on the eth0 interface?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set 'BOOTPROTO=dhcp' in /etc/sysconfig/network-scripts/ifcfg-eth0.
Option D is correct because on Red Hat-based Linux distributions, the recommended way to configure an interface for DHCP is to set 'BOOTPROTO=dhcp' in the interface configuration file /etc/sysconfig/network-scripts/ifcfg-eth0. This instructs the network service to use the DHCP protocol to obtain an IP address automatically from a DHCP server. The value 'dhcp' is the standard keyword recognized by the ifcfg scripts, not 'dhclient'.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Set 'BOOTPROTO=dhclient' in /etc/sysconfig/network-scripts/ifcfg-eth0.
Set 'BOOTPROTO=dhcp' in /etc/sysconfig/network-scripts/ifcfg-eth0.
Why this is correct
Standard for network-scripts.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the DHCP client configuration keyword 'dhcp' with the client program name 'dhclient', or mistakenly think that editing the DHCP server configuration file is the correct way to configure a client to obtain an IP automatically.
Detailed technical explanation
How to think about this question
When BOOTPROTO=dhcp is set, the ifup script runs dhclient (or dhcpcd, depending on the distribution) to send a DHCPDISCOVER broadcast, receive a DHCPOFFER, and then request the offered IP via DHCPREQUEST. The DHCP client then manages the lease renewal and release, and the interface configuration is updated dynamically. In real-world scenarios, this method is preferred for servers that need a dynamic IP but may also use DHCP reservations on the server side for consistency.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the LPIC-2 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
