Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Create a separate sandbox environment that is isolated from production and uses mock endpoints for RFC calls.
Why this is correct
Isolation prevents unintended effects on production.
- ✗
Use the same RFC destinations as production but disable the external system.
Why it's wrong here
Disabling external system may cause errors; better to mock.
- ✗
Set up a VPN between the sandbox and the external system to test real connectivity.
Why it's wrong here
Exposes external system to test traffic; not isolated.
- ✗
Configure the sandbox to use the production RFC endpoints but with read-only access.
Why it's wrong here
Read-only may not be supported; risk of data modification.
