SNOW-CAD Working with Data Practice Question
Which THREE are best practices when working with data imports via Import Sets? (Choose three.)
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
✓
Ensure all target fields are mapped to avoid missing data.
Options A, B, and D are correct. Ensuring all target fields are mapped avoids missing data. Using the coalesce field prevents duplicate records. Using a staging table allows data validation before transforming. Option C is wrong because mapping import set rows directly to the target table without a transform is not a best practice; transforms allow data manipulation and cleansing. Option E is wrong because skipping the transform map would bypass necessary transformations and validations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ensure all target fields are mapped to avoid missing data.
Why this is correct
Complete mapping prevents data loss.
- ✓
Use the 'Coalese' field to prevent duplicate records.
Why this is correct
Coalesce helps in updating existing records instead of creating duplicates.
- ✗
Map import set rows directly to the target table columns without using a transform.
Why it's wrong here
Direct mapping without transform bypasses field transformations and scripts.
- ✓
Use a staging table to validate data before transforming.
Why this is correct
Staging allows data validation before target insertion.
- ✗
Skip creating a transform map to speed up the import.
Why it's wrong here
Transform maps are essential for mapping and data manipulation.
