SNOW-CAD Working with Data Practice Question
A data source is configured to import XML files from a REST endpoint. The XML contains nested elements. To properly map the data, which transform map feature is most useful?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Scripted transform with GlideRecord queries.
Scripted transforms allow custom JavaScript to parse and map nested XML elements using GlideRecord or other APIs, providing full flexibility when dot-walk notation is insufficient or not supported. Option A is incorrect because field mapping with dot-walk notation may not handle complex nested structures or special cases, and the reference to 'setEngine(false)' is invalid. Option B is incorrect because adjusting XML parsing settings affects parsing but not mapping. Option C is incorrect because choice mapping is for choice fields, not for nested data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Field mapping using dot-walk notation in 'Field name to map to' column.
Why it's wrong here
Field mapping using dot-walk notation is a basic feature but may not handle all nested XML structures without scripting; it is less flexible than scripted transforms.
- ✗
Adjust the data source's 'XML parsing' settings.
Why it's wrong here
Adjusting XML parsing settings affects how the XML is parsed, not how nested elements are mapped to fields.
- ✗
Use 'Choice mapping' to map nested values.
Why it's wrong here
Choice mapping is used to map values to choice lists, not for mapping nested XML elements.
- ✓
Scripted transform with GlideRecord queries.
Why this is correct
Scripted transforms provide full control to parse and map nested XML elements using JavaScript, making them the most useful for complex data structures.
