LPIC-2 Linux Kernel and System Startup Practice Question
This LPIC-2 practice question tests your understanding of linux kernel and system startup. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 THREE of the following are standard steps in compiling and installing a custom Linux kernel from source? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
make menuconfig
Option B is correct because `make menuconfig` is a standard step that launches a text-based menu-driven interface for configuring kernel options before compilation. This step allows the user to select which features, drivers, and modules to include in the kernel build, generating the `.config` file that guides the subsequent compilation.
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.
✗
make modules_install
Why it's wrong here
This installs the compiled modules, but it is typically run as part of 'make install', so it is not always a separate step.
✓
make menuconfig
Why this is correct
This step configures the kernel features and modules before compilation.

✓
make install
Why this is correct
This installs the kernel, runs modules_install, and updates the bootloader.

✓
make
Why this is correct
This compiles the kernel image and modules.

✗
make oldconfig
Why it's wrong here
This is used to update an existing .config file for a new kernel version, not a standard step for a fresh compilation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse `make modules_install` as a core compilation step rather than a post-compilation installation step, and may overlook that `make install` is the standard step for installing the kernel image itself, while `make oldconfig` is a configuration update tool, not a standard step in a fresh build.
Detailed technical explanation
How to think about this question
The standard sequence for compiling and installing a custom Linux kernel from source is: `make menuconfig` (or equivalent configuration target), `make` (to compile the kernel and modules), `make modules_install` (to install modules), and `make install` (to copy the kernel image and System.map to `/boot` and update the bootloader). The `make` step invokes the top-level Makefile, which reads `.config` and compiles the kernel image (e.g., `vmlinuz`) and all selected modules. A common real-world scenario is building a minimal kernel for an embedded system, where omitting `make modules_install` would leave modules uninstalled, causing driver failures at boot.
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.
