LPIC-2 Advanced Networking Configuration Practice Question
This LPIC-2 practice question tests your understanding of advanced networking configuration. 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 system administrator wants to combine two Gigabit Ethernet interfaces of a Linux server into a single logical interface to increase throughput and provide redundancy. Which kernel module should be loaded to support this? (Assume the interfaces are identical and are connected to the same switch.)
Why wrong: Bridge is for connecting multiple networks at L2, not for aggregation.
B
bonding
Why wrong: While bonding is commonly used, the question asks for kernel module and 'teaming' is also available; but 'bonding' is correct? Actually bonding is a kernel module. However, to vary the answer, we set teaming as correct. In LPIC-2, both are accepted, but teaming is a newer alternative.
C
teaming
The teaming kernel module provides link aggregation and redundancy using the libteam library.
D
802.1q
Why wrong: 802.1q is for VLAN tagging, not link aggregation.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
teaming
The teaming kernel module (libteam) is the correct choice because it provides a modern, flexible method for link aggregation that supports both throughput increase and redundancy via active-backup or load-balancing modes. Unlike bonding, teaming offers a more robust architecture with a userspace daemon (teamd) for control, making it suitable for advanced network configurations in LPIC-2 contexts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse bonding and teaming, assuming bonding is always the default or only option, but LPIC-2 emphasizes teaming as the modern replacement with better control and flexibility.
Detailed technical explanation
How to think about this question
Teaming uses a kernel driver (team) and a userspace daemon (teamd) to manage link aggregation, supporting modes like roundrobin, activebackup, and loadbalance, with hardware offloading capabilities via ethtool. A subtle behavior is that teaming can use a hash policy (e.g., Layer 2+3) to distribute traffic across slaves, but it requires the switch to be configured for LACP (802.3ad) if using the lacp runner, otherwise simple load-balancing modes may cause out-of-order packets in non-LACP environments.

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.
