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.
Exhibit
Refer to the exhibit.
$ dpkg -l | grep -E '^ii|^rc'
ii curl 7.68.0-1ubuntu2 amd64 command line tool for transferring data
rc ftp 0.17-34 amd64 classic FTP client
ii wget 1.20.3-1ubuntu1 amd64 non-interactive network downloader
Refer to the exhibit. Based on the dpkg output, what is the status of the 'ftp' package?

A
Removed but configuration files remain.
The 'rc' status indicates removed with config files.
B
Half-configured.
Why wrong: That would be 'iF' or similar.
C
Installed and up-to-date.
Why wrong: That would be 'ii'.
D
Not installed at all.
Why wrong: If not installed, it would not appear in this grep.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Removed but configuration files remain.
The 'dpkg' output shows 'rc' in the status field, which stands for 'removed' (the package has been deleted) but 'config-files' remain. This means the package was removed using 'dpkg --purge' or 'apt-get remove' without the '--purge' option, leaving behind configuration files in /etc.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
LPI often tests the distinction between 'removed' (package binary gone) and 'purged' (everything gone), where candidates mistakenly think 'rc' means the package is still installed or that config files are automatically removed.

That would be 'iF' or similar.
Detailed technical explanation
How to think about this question
The dpkg status field uses a two-character code: the first character indicates the desired action (e.g., 'r' for remove, 'i' for install) and the second character indicates the actual state (e.g., 'c' for config-files, 'i' for installed). The 'rc' status is a common leftover after a standard 'apt-get remove' (which does not purge configs), and can be cleaned up with 'dpkg --purge' or 'apt-get purge'. In real-world scenarios, leftover config files can cause conflicts if the package is reinstalled, as the old configuration may override defaults.
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.
