問題文
A team must manage an API that is implemented by an application they cannot modify, because it is maintained by a different vendor. Which approach lets them apply policies to it?
選択肢
- Add an autodiscovery element to the application, which requires no change to it since the element is supplied from API Manager rather than from the project.
- Apply the policies directly to the implementation from API Manager, because a managed API instance takes effect as soon as its address matches the address of a running application anywhere in the organization.
- Deploy a proxy in front of the existing implementation and manage the proxy, since nothing has to be added inside the application itself.
- Ask the vendor to enforce the rules inside their code.
