Multiple versions of a Vlocity Calculation Matrix can be enabled, although only one matrix will be used for the calculation.

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (A)

Calculation Matrices in OmniStudio support versioning, so you can create and enable multiple versions to support testing, staging, and rollback plans. The system lets you have several versions available, but when a calculation runs, it uses a single designated version—the one configured as the active version for that matrix. This means you can have several versions enabled in the org, yet the actual calculation is deterministic because only the chosen active version is applied. That’s why the statement is true: you can have multiple versions, but only one is used for the calculation at runtime.
