LPIC-2 Advanced Networking Configuration Practice Question
After adding a new network interface, the system assigns it the name 'enp0s3' instead of 'eth0'. Which of the following best describes the reason for this change?
⚠ Common exam trap
Test-takers frequently assume 'eth0' is the only valid naming convention and think the change is due to a fault or randomness, rather than recognizing the deliberate shift to predictable naming for stability in multi-interface environments.
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
✓
The system uses the new predictable network interface naming scheme.
The system uses the predictable network interface naming scheme (also known as Consistent Network Device Naming), introduced in systemd/udev. This scheme assigns names like 'enp0s3' based on the physical location of the device (e.g., 'en' for Ethernet, 'p0' for PCI bus 0, 's3' for slot 3), replacing the traditional 'eth0' naming that could change unpredictably across reboots or hardware additions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The system uses the new predictable network interface naming scheme.
Why this is correct
udev rules based on firmware/PCI topology generate names like enp0s3.
- ✗
The kernel assigns names randomly to avoid conflicts.
Why it's wrong here
Names are not random; they follow a predictable pattern.
- ✗
The network card is faulty, causing the kernel to rename it.
Why it's wrong here
Faulty hardware does not cause rename; it may cause failure.
- ✗
The interface is a virtual device, so it gets a non-standard name.
Why it's wrong here
Virtual devices usually have names like virbr0, not enp0s3.
