How an automation starts (schedule, file drop or trigger), why its schedule must fit its duration, what happens to a run that is due while another is still going, how Pause, Skip and Stop differ, and how file drop folders, file name patterns and queuing decide whether a dropped file starts a run.

**Official exam objective:**

> Given a customer scenario, build the appropriate Automation Studio solution.

## What the exam expects

- Choose a scheduled, file drop or trigger starting source from how the automation must start.
- Align a schedule's frequency with the automation's run duration, and predict what happens to a run that is due while another run is still going.
- Choose among Pause, Skip and Stop given what must happen to the current run and to future runs.
- Configure a file drop automation with a folder or a file name pattern, decide whether queuing stays on, and diagnose why a dropped file didn't start a run.
- Key terms: **starting source** (what starts an automation); **file drop automation** (starts when a file reaches the Enhanced FTP); **file name pattern** (the name rule a dropped file must match); **queuing** (holding extra files to start later runs); **Run Log** (the automation's record of runs, including skipped ones).

## Check yourself

- Why doesn't a newly scheduled automation run after you save its schedule?
- Where do you find scheduled runs skipped because wait activities created overlapping times?
- When does a file drop automation randomly pick which automation runs?
- Which starting source reads file extensions?
