when should the full copy sandbox be refreshed?

At Universal Containers, each admin and developer use a separate developer pro sandbox. Configuration and code are then migrated to a partial data sandbox for combination and initial testing. Once approved the configuration and code are then migrated to a full copy sandbox for final load and regression testing before going to production.

when should the full copy sandbox be refreshed?
A . After each push from the partial data sandbox.
B . After user acceptance testing is complete.
C . After each major release to production.
D . After a new user is added to production.

Answer: C

Explanation:

This answer is correct because it is a recommended time to refresh the full copy sandbox. Refreshing the full copy sandbox after each major release to production can help ensure that the sandbox has the most updated data and metadata from production, which can facilitate testing and development activities. Refreshing the full copy sandbox too frequently can be costly and time-consuming, as it consumes a lot of storage space and requires data masking or anonymization.
