SNOW-CAD Practice Question: Application development using ServiceNow Studio
A developer is building an application in ServiceNow Studio. Which three of the following are correct practices when using Studio? (Choose three.)
⚠ Common exam trap
Watch out — candidates often think manually setting the version number is harmless or necessary for release management, but ServiceNow's automatic versioning is tied to the application's publish lifecycle and update set tracking, making manual edits a source of synchronization errors.

Correct answer & explanation
✓
Utilize the Studio Debugger to test business rules and script includes.
The Studio Debugger allows developers to set breakpoints and step through business rules and script includes in real time, enabling precise testing of server-side logic within the scoped application context. This is essential for validating script behavior without deploying to a separate test instance.

- ✓
Utilize the Studio Debugger to test business rules and script includes.
Why this is correct
