- A
userdel contractor1
Why wrong: Deletes the user but leaves the home directory.
- B
passwd -d contractor1
Why wrong: Deletes the password, not the account.
- C
userdel -r contractor1
Removes the user and their home directory (-r).
- D
deluser --remove-home contractor1
Why wrong: deluser is Debian-specific; the question is distribution-agnostic for LFCS, so userdel is the standard command.

LFCS User and Group Management Practice Question
This LFCS practice question tests your understanding of user and group management. 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.
A temporary contractor 'contractor1' has left the company. The administrator needs to remove the user account and all associated files in the home directory. Which command accomplishes this?
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.
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
✓
userdel -r contractor1
Option C is correct because the `userdel -r contractor1` command removes the user account and, with the `-r` flag, also deletes the user's home directory and mail spool. This is the standard Linux command to completely remove a user and their associated files, as required by the scenario.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
deluser is Debian-specific; the question is distribution-agnostic for LFCS, so userdel is the standard command.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may choose Option A, thinking `userdel` alone removes everything, or Option D, assuming `deluser` is universally available, when the LFCS exam tests the standard `userdel -r` command that works across all major Linux distributions.
Trap categories for this question
Command / output trap
deluser is Debian-specific; the question is distribution-agnostic for LFCS, so userdel is the standard command.
Detailed technical explanation
How to think about this question
The `userdel -r` command removes the user's entry from `/etc/passwd`, `/etc/shadow`, and `/etc/group`, and deletes the home directory (typically `/home/contractor1`) and the user's mail spool (`/var/mail/contractor1`). Without the `-r` flag, the home directory becomes an orphan, which can lead to security risks or disk space waste. In real-world scenarios, administrators often combine `userdel -r` with `find / -user contractor1` to catch any files outside the home directory, though the exam focuses on the standard behavior.
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 LFCS 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.
