How should the consultant recommend testing be conducted?
A . Create a new Sandbox, populate it with data, and ask volunteers to test it with use cases.
B . Create test Accounts and Opportunities in Production and ask volunteers to test it with use cases.
C . Create a new Developer Edition org, populate it with data, and ask volunteers to test it with use cases.
D . Create a new Sandbox and ask volunteers to test it with use cases.

Answer: A

Explanation:

To test the changes and updates before go-live, the consultant should recommend creating a new Sandbox, populating it with data, and asking volunteers to test it with use cases. A Sandbox is a copy of the production org that can be used for development, testing, and training purposes. A Sandbox allows the consultant to test the changes in a safe and isolated environment without affecting the live data and users. A Sandbox can also be refreshed to get the latest data and metadata from the production org.
