LPIC-1 Linux Installation and Package Management Practice Question
This LPIC-1 practice question tests your understanding of linux installation and package management. 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.
An RPM-based system has a package 'example-1.0' installed, but a newer version 'example-2.0' is available in a repository. Which command will upgrade the package?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "which command"
Why it matters: Tests specific CLI syntax. Recall the exact command and its required context — near-synonyms and partial matches are common distractors.
Why wrong: This requires downloading the .rpm file first; the question implies using the repository.
B
yum update example
yum update updates the specified package from the repository.
C
yum check-update example
Why wrong: This only checks for available updates, does not perform install.
D
yum install example
Why wrong: This would install the latest version, but if the package is already installed, it will attempt a reinstall or upgrade; however, 'update' is the standard command for upgrades.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
yum update example
Option B is correct because 'yum update example' is the standard command to upgrade a specific package to the latest available version from configured repositories. YUM automatically resolves dependencies and retrieves the newer package from the repository, making it the appropriate tool for upgrading from a repository source.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
rpm -Uvh example-2.0.rpm
Why it's wrong here
This requires downloading the .rpm file first; the question implies using the repository.
✓
yum update example
Why this is correct
yum update updates the specified package from the repository.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'yum install' (which installs a new package or upgrades if already installed but is not the standard upgrade command) with 'yum update' (the explicit command for upgrading installed packages), or they mistakenly think 'rpm -Uvh' works with repository packages without a local file.

Command / output trap
This would install the latest version, but if the package is already installed, it will attempt a reinstall or upgrade; however, 'update' is the standard command for upgrades.
Detailed technical explanation
How to think about this question
Under the hood, YUM uses repository metadata (repomd.xml and primary.xml.gz) to compare the installed package version with the latest available version. The 'update' command triggers a transaction that downloads the new RPM, runs pre/post scriptlets, and updates the RPM database. In real-world scenarios, using 'yum update' ensures that dependency changes between versions are handled automatically, whereas 'rpm -Uvh' on a local file can lead to dependency hell if the new version requires updated libraries.
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-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.
