SNOW-CAD Working with Data Practice Question
A developer is designing a data architecture for a multi-tenant environment where each company's data must be isolated. Which TWO strategies can achieve this? (Choose two.)
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
✓
Implement domain separation.
Options A and E are correct. Domain separation (A) provides built-in data isolation by partitioning data based on domains, ensuring each company sees only its own data. Separate tables for each company (E) physically isolate data at the database level. Option B (ACLs) adds security but does not inherently isolate data in a multi-tenant architecture. Option C (database views) filters data but does not enforce isolation at the application layer. Option D (GlideRecord conditions) relies on developer discipline and is not a robust architectural solution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement domain separation.
Why this is correct
Domain separation natively partitions data by domain.
- ✗
Use access control lists (ACLs) on each record.
Why it's wrong here
ACLs can provide security but may not prevent all cross-tenant data access if misconfigured.
- ✗
Create database views that filter data by company.
Why it's wrong here
Views do not enforce data isolation at the application layer.
- ✗
Add a condition to every GlideRecord query to filter by company.
Why it's wrong here
Requires strict adherence by all developers; not architectural.
- ✓
Use separate tables for each company.
Why this is correct
Physical separation ensures data is completely isolated.
