LPIC-1 Linux Installation and Package Management Practice Question
A system has multiple APT repositories configured. The administrator needs to ensure that for a specific package, the version from a particular repository is always preferred over others, regardless of version number. Which configuration would achieve this?
⚠ Common exam trap
It's easy for candidates to confuse apt-mark hold (which only freezes the installed version) with APT pinning (which controls version selection from repositories), leading them to choose option B instead of the correct pinning configuration.
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
✓
Creating a file in /etc/apt/preferences.d/ with a high Pin-Priority for that package and origin
APT's pinning mechanism, configured via files in /etc/apt/preferences.d/, allows an administrator to assign a high Pin-Priority to a specific package from a particular origin (repository). This ensures that version is always preferred during dependency resolution and upgrades, overriding the default version comparison logic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Editing /etc/apt/sources.list and setting the release in sources.list
Why it's wrong here
Does not pin a specific package.
- ✗
Using apt-mark hold on the package after installing from desired repository
Why it's wrong here
Prevents upgrade but does not preference selection.
- ✓
Creating a file in /etc/apt/preferences.d/ with a high Pin-Priority for that package and origin
Why this is correct
APT pinning allows persistent preference.
- ✗
Adding the repository and using apt-get install -t release package
Why it's wrong here
Only works for installation, not ongoing preference.
