# Knowledge Check: Welcome to ROOT_

---

**1. If your Lab environment is recreated, what happens to a file you saved inside it, and
what happens to your completed Labs so far?**

*Answer:* The file disappears — nothing inside the Lab persists across a recreation. Your
completed Labs and course progress are unaffected — those are stored on RootNode's servers, not
in the Lab, and survive regardless of what happens to any Lab environment.

**2. A Lab task fails your validation check. What should that tell you?**

*Answer:* Specifically what isn't correct yet, based on the real current state of your
environment — it's diagnostic information to act on, not a penalty.

**3. Name one thing to try before assuming a Lab is "just broken."**

*Answer:* Check the available hints (revealed one at a time), and if the environment itself
genuinely seems broken rather than the task being hard, use Reset Scenario & Environment to
rebuild it cleanly.

## Instructor Notes

**Facilitation:** This is a good moment to actually demonstrate a Lab reset live if you have
time — students remember "I saw it happen and nothing bad occurred" far better than being told
it's safe.

**Approximate timing:** 3 minutes.
