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.
A laptop user frequently moves between different networks. The administrator wants the DNS configuration to update automatically when the laptop connects to a new network via DHCP. Which service or tool is most appropriate for this task?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
NetworkManager
NetworkManager is the most appropriate tool because it is designed to manage network connections on modern Linux systems, automatically detecting network changes and reconfiguring DNS settings based on DHCP-provided information. It integrates with various backends (e.g., systemd-resolved, resolvconf) to update the system's DNS configuration dynamically, making it ideal for a laptop that frequently moves between networks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
NetworkManager
Why this is correct
NetworkManager handles DNS configuration dynamically when network changes occur.
Related concept
Read the scenario before looking for a memorised answer.
✗
systemd-resolved
Why it's wrong here
systemd-resolved provides DNS resolution but does not interact directly with DHCP on its own.
✗
dhcpcd
Why it's wrong here
dhcpcd can update resolv.conf directly, but it is not as comprehensive as NetworkManager for laptop users.
✗
resolvconf
Why it's wrong here
resolvconf is a utility to manage resolv.conf, but it typically requires integration with a DHCP client.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse systemd-resolved as a standalone solution for dynamic DNS updates, but it requires a network manager like NetworkManager to trigger the reconfiguration when the network changes.
Detailed technical explanation
How to think about this question
NetworkManager uses a plugin-based architecture, where the 'keyfile' plugin stores connection profiles, and it can delegate DNS configuration to systemd-resolved via the 'dns=systemd-resolved' setting in /etc/NetworkManager/NetworkManager.conf. In a real-world scenario, when a laptop connects to a new Wi-Fi network, NetworkManager receives DHCP lease information, updates the DNS servers, and optionally flushes the DNS cache to ensure immediate resolution of new domain names.
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.
