This LPIC-1 practice question tests your understanding of administrative tasks. 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.
0 * * * 1-6 /script.sh
Refer to the exhibit. The job runs every hour but the administrator notices that it does not execute on Sundays. Which cron syntax element is responsible?
0 * * * 1-6 /script.sh
The minute field
Why wrong: Minute is 0, so top of each hour.
The hour field
Why wrong: Hour is *, so every hour.
The month field
Why wrong: Month is *, so all months.
The day-of-week field
Correct: 1-6 excludes Sunday.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The day-of-week field
The day-of-week field (the 5th field in a cron expression) controls which days of the week the job runs. If this field is set to 1-6 (Monday–Saturday) or explicitly excludes 0/7 (Sunday), the job will not execute on Sundays. Since the job runs every hour but not on Sundays, the day-of-week field is responsible.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
The trap here is that candidates often confuse the day-of-month field (3rd field) with the day-of-week field (5th field), or assume the hour field controls daily execution, when in fact the day-of-week field is the only one that can selectively exclude a specific weekday like Sunday.
Detailed technical explanation
In cron, the day-of-week field accepts values 0-7 (where both 0 and 7 represent Sunday) and can use ranges, lists, or step values. A common configuration to exclude Sundays is to set this field to '1-6' or 'MON-SAT'. The cron daemon evaluates all time fields as logical AND conditions, so if the day-of-week field does not match Sunday, the job is skipped regardless of other fields.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
