Quick Answer
The correct answers are insmod and modprobe, as both are commands used to manage kernel modules in Linux. Insmod directly inserts a module into the running kernel but does not resolve dependencies, making it suitable only when you are certain all required modules are already loaded. Modprobe, on the other hand, is the recommended tool because it automatically handles dependencies and respects configuration files in /etc/modprobe.d/, making it far more robust for routine administration. On the LPIC-2 exam, this question tests your understanding of module management fundamentals and the distinction between low-level and high-level utilities. A common trap is selecting rmmod or lsmod, which remove or list modules rather than load them, or confusing insmod with modprobe’s dependency resolution. Remember the mnemonic: “Insmod inserts, but modprobe manages the mess.”
This LPIC-2 practice question tests your understanding of linux kernel and system startup. 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.
Which TWO of the following commands are used to manage kernel modules? (Select TWO.)
lsmod
Why wrong: lsmod lists loaded modules, does not manage them.
insmod
insmod loads a single module directly.
modprobe
modprobe is used to load and unload modules with dependency resolution.
rmmod
Why wrong: rmmod removes modules, but the question asks for managing, including loading.
depmod
Why wrong: depmod generates dependency files, not manage modules directly.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
insmod
B (insmod) is correct because it directly inserts a kernel module into the running kernel, though it does not resolve dependencies automatically. C (modprobe) is correct because it is the recommended tool for managing kernel modules, as it automatically loads dependencies and handles module parameters via configuration files in /etc/modprobe.d/.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
lsmod
Why it's wrong here
lsmod lists loaded modules, does not manage them.
insmod
Why this is correct
insmod loads a single module directly.

rmmod

depmod
Why it's wrong here
depmod generates dependency files, not manage modules directly.
Common exam traps
The trap here is that candidates often confuse 'managing' modules with 'listing' or 'removing' them, and may incorrectly select lsmod or rmmod, or fail to recognize that modprobe is the primary management command while insmod is a lower-level alternative.
Detailed technical explanation
Under the hood, insmod uses the init_module() system call to load a single .ko file into kernel space, but it fails if any symbol dependencies are missing. modprobe leverages the dependency map created by depmod to load a module and all its prerequisites recursively, and it also respects blacklists and alias directives in /etc/modprobe.d/. In real-world scenarios, using insmod for a module with dependencies will result in 'Unknown symbol' errors, making modprobe the safer choice for production systems.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
