Answer: C

Explanation:

The Appian cloud instance needs to be able to access the REST API endpoint within the customer’s internal network. By adding the IP address ranges of the Appian cloud to the allowed list, you ensure network-level access to this API from the Appian cloud instance.

Options A (exposing the API as a SOAP-based web service) and B (deploying the API/service into Appian Cloud) both involve changing the format or location of the API, which may not align with the customer’s needs or policies.

Option D (setting up a VPN tunnel) is also a viable solution but is typically more complex than simply adding IP addresses to an allow list, requiring more configuration and maintenance.
