An Order API must be designed that contains significant amounts of integration logic and involves the invocation of the Product API.
The power relationship between Order API and Product API is one of "Customer/Supplier", because the Product API is used heavily throughout the organization and is developed by a dedicated development team located in the office of the CTO.
What strategy should be used to deal with the API data model of the Product API within the Order API?

• A.Convince the development team of the Product API to adopt the API data model of the Order API such that the integration logic of the Order API can work with one consistent internal data model
• B.Work with the API data types of the Product API directly when implementing the integration logic of the Order API such that the Order API uses the same (unchanged) data types as the Product API
• C.Implement an anti-corruption layer in the Order API that transforms the Product API data model into internal data types of the Order API
• D.Start an organization-wide data modeling initiative that will result in an Enterprise Data Model that will then be used in both the Product API and the Order API

What is a best practice when building System APIs?

• A.Document the API using an easily consumable asset like a RAML definition
• B.Model all API resources and methods to closely mimic the operations of the backend system
• C.Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs
• D.Expose to API clients all technical details of the API implementation's interaction wifch the backend system

Refer to the exhibit. An organization is running a Mule standalone runtime and has configured Active Directory as the Anypoint Platform external Identity Provider. The organization does not have budget for other system components.

What policy should be applied to all instances of APIs in the organization to most effecuvelyKestrict access to a specific group of internal users?

• A.Apply an IP whitelist policy; only the specific users' workstations will be in the whitelist
• B.Apply a basic authentication - LDAP policy; the internal Active Directory will be configured as the LDAP source for authenticating users
• C.Apply a client ID enforcement policy; the specific group of users will configure their client applications to use their specific client credentials
• D.Apply an OAuth 2.0 access token enforcement policy; the internal Active Directory will be configured as the OAuth server

A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?

• A.When there are a large number of existing common assets shared by development teams
• B.When various teams responsible for creating APIs are new to integration and hence need extensive training
• C.When development is already organized into several independent initiatives or groups
• D.When the majority of the applications in the application network are cloud based
