LPIC-2 Advanced Networking Configuration Practice Question
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.)
⚠ Common exam trap
The trap is that candidates may choose teaming because it is a newer technology, but LPIC-2 objectives focus on bonding as the traditional and standard method for link aggregation.
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
✓
bonding
The bonding kernel module (bonding) is the correct choice for combining two Gigabit Ethernet interfaces into a single logical interface to increase throughput and provide redundancy. Bonding is a standard Linux kernel module for link aggregation that supports various modes (e.g., active-backup, 802.3ad). On LPIC-2, bonding is the expected technology for interface bonding.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
bridge
Why it's wrong here
The bridge module is used for bridging (layer 2 switching) between interfaces, not for combining interfaces for throughput and redundancy.
- ✓
bonding
Why this is correct
Correct. The bonding module is the standard Linux kernel module for link aggregation, providing both load balancing and failover capabilities.
- ✗
teaming
Why it's wrong here
The teaming module (libteam) is a modern alternative but is not covered in LPIC-2 objectives; bonding is the expected answer.
- ✗
802.1q
Why it's wrong here
The 802.1q module is used for VLAN tagging, not for interface bonding.
