Get Cloudy Consulting (GCC) needs an environment to onboard new hires as well as develop, implement, and test new requirements. Which type of environment should OCC use?

A Sandbox is a copy of the production org that allows development, implementation, testing, and training in an isolated environment. It does not affect live production data or users. Organizations use sandboxes specifically for the onboarding and development lifecycle described in the scenario.

Production is the live org used by real users and contains real data - using it for development or onboarding training risks corrupting or exposing production data.

A Trailhead Playground is a lightweight org designed for completing Trailhead learning modules, not for enterprise onboarding or development workflows.

Developer Edition is a free standalone Salesforce org intended for individual developers to learn and build apps, and is not connected to a company's production org.
