- A
Step 1: Run 'crontab -e' to open the crontab editor. Step 2: Add the line '0 2 * * * /path/to/script'. Step 3: Save and exit the editor. Step 4: Run 'crontab -l' to verify the job is scheduled.
This is the correct sequence. First, you open the crontab file for editing. Then you add the cron expression with correct time fields (minute 0, hour 2, then asterisks for day, month, weekday). After saving, you verify the job exists.
- B
Step 1: Add the line '0 2 * * * /path/to/script' directly to the crontab. Step 2: Run 'crontab -e' to open the editor. Step 3: Save and exit the editor. Step 4: Run 'crontab -l' to verify.
Why wrong: This is incorrect because you cannot add a line to the crontab without first opening it for editing. The crontab -e command must be run before any line addition.
- C
Step 1: Run 'crontab -e' to open the editor. Step 2: Save and exit the editor immediately. Step 3: Add the line '0 2 * * * /path/to/script'. Step 4: Run 'crontab -l' to verify.
Why wrong: This is incorrect because saving before adding the cron line means no job was added. You must add the line before saving.
- D
Step 1: Run 'crontab -l' to verify existing jobs. Step 2: Run 'crontab -e' to open the editor. Step 3: Add the line '0 2 * * * /path/to/script'. Step 4: Save and exit.
Why wrong: This is incorrect because verifying jobs before editing is not necessary and does not affect the configuration. The correct order is to edit first, then verify after saving.
LFCS Storage Management Practice Question
This LFCS practice question tests your understanding of storage 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.
Order the steps to configure a cron job that runs a script every day at 2 AM.

Correct answer & explanation
Step 1: Run 'crontab -e' to open the crontab editor. Step 2: Add the line '0 2 * * * /path/to/script'. Step 3: Save and exit the editor. Step 4: Run 'crontab -l' to verify the job is scheduled.
The correct order to configure a cron job is: open the crontab file with 'crontab -e', add the cron expression with the correct time fields (minute, hour, day, month, weekday) and the script path, save the file, and then verify with 'crontab -l'. Common mistakes include adding the line before opening the editor, saving before adding, or verifying before editing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Command / output trap
This is incorrect because you cannot add a line to the crontab without first opening it for editing. The crontab -e command must be run before any line addition.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
