A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-5Security Operations

An analyst schedules a nightly enrichment script with this crontab entry:

0 2 * * 1 /opt/soc/enrich.sh

When does it actually run?

At 02:00 dailyDaily execution would need the day-of-week field left as an asterisk.
Hourly on MondaysHourly runs would need an asterisk in the hour field.
At 02:00 each MondayCorrect · your answerCorrect: minute 0, hour 2, day-of-week 1 is 02:00 each Monday.
At 02:00 on the month's first dayMonth-day scheduling uses the third field, which is an asterisk here.

Correct.

Concept

Scheduled automation lives or dies on the field order of the schedule format. Reading positions wrong shifts a job from weekly to daily, and the mistake only surfaces when the output gap is noticed.

Why C

The fields run minute, hour, day of month, month, day of week. Here minute 0, hour 2, and day-of-week 1 restrict the run to 02:00 on Mondays, with the day-of-month and month fields wide open.
