This LPIC-1 practice question tests your understanding of devices, filesystems and fhs. 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.
According to the Filesystem Hierarchy Standard (FHS), in which directory should third-party static libraries be installed?
/lib
Why wrong: /lib is for libraries required by binaries in /bin and /sbin for booting.
/usr/local/lib
Why wrong: /usr/local is for locally installed software, not third-party distribution packages.
/opt/lib
Why wrong: /opt is for self-contained packages; libraries are usually placed under the package's own directory within /opt.
/usr/lib
Third-party libraries that are not part of the base system should go in /usr/lib.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
/usr/lib
The Filesystem Hierarchy Standard (FHS) specifies that /usr/lib is the correct directory for third-party static libraries that are part of the system's package management. This directory holds libraries that are not dynamically linked and are required by programs in /usr/bin and /usr/sbin, ensuring consistency across the system.
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.
/lib
Why it's wrong here
/lib is for libraries required by binaries in /bin and /sbin for booting.
/usr/local/lib
Why it's wrong here
/usr/local is for locally installed software, not third-party distribution packages.
/opt/lib
Why it's wrong here
/opt is for self-contained packages; libraries are usually placed under the package's own directory within /opt.
/usr/lib
Why this is correct
Third-party libraries that are not part of the base system should go in /usr/lib.

Common exam traps
The trap here is that candidates often confuse /usr/local/lib with the correct location for system-managed third-party libraries, mistakenly thinking 'local' implies any locally installed third-party software, when in fact /usr/local is for site-specific, non-package-manager software.
Detailed technical explanation
Static libraries (with .a extension) are linked into executables at compile time, unlike shared libraries (.so) which are loaded at runtime. The FHS distinguishes between /usr/lib (for distribution-managed static libraries) and /usr/local/lib (for locally built software), ensuring that package managers like dpkg or rpm can track and update libraries without conflicts. A real-world scenario: installing a static library via apt on Debian places it in /usr/lib, while compiling from source with --prefix=/usr/local puts it in /usr/local/lib.
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-1 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.
