質問 1：
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. Expose to API clients all technical details of the API implementation's interaction wifch the backend system
D. Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs
正解：B

質問 2：
What is typically NOT a function of the APIs created within the framework called API-led connectivity?
A. They allow for innovation at the user Interface level by consuming the underlying assets without being aware of how data Is being extracted from backend systems.
B. They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.
C. They can compose data from various sources and combine them with orchestration logic to create higher level value.
D. They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

質問 3：
A code-centric API documentation environment should allow API consumers to investigate and execute API client source code that demonstrates invoking one or more APIs as part of representative scenarios.
What is the most effective way to provide this type of code-centric API documentation environment using Anypoint Platform?
A. Ensure the APIs are well documented through their Anypoint Exchange entries and API Consoles and share these pages with all API consumers
B. Enable mocking services for each of the relevant APIs and expose them via their Anypoint Exchange entry
C. Create API Notebooks and include them in the relevant Anypoint Exchange entries
D. Make relevant APIs discoverable via an Anypoint Exchange entry

質問 4：
Say, there is a legacy CRM system called CRM-Z which is offering below functions:
1. Customer creation
2. Amend details of an existing customer
3. Retrieve details of a customer
4. Suspend a customer
A. Implement different system APIs named createCustomerInCRMZ, amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as they are modular and has seperation of concerns
B. Implement a system API named customerManagement which has all the functionalities wrapped in it as various operations/resources
C. Implement different system APIs named createCustomer, amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns

A. IPwhitelist
B. Auth 2 token enforcement
C. Client ID enforcement
D. SLA-based rate limiting
正解：D

質問 6：
An API has been updated in Anypoint exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the APIs public portal.
The API endpoint does NOT change in the new version. How should the developer of an API client respond to this change?
A. The API client code only needs to be changed if it needs to take advantage of the new features
B. The API clients need to update the code on their side and need to do full regression
C. The API producer should be requested to run the old version in parallel with the new one
D. The API producer should be contacted to understand the change to existing functionality
正解：A

質問 7：
What is true about where an API policy is defined in Anypoint Platform and how it is then applied to API instances?
A. The API policy is defined in API Manager, and then applied to ALL API instances in the specified environment
B. The API policy Is defined In API Manager for a specific API Instance, and then ONLY applied to the specific API instance
C. The API policy Is defined in API Manager and then automatically applied to ALL API instances
D. The API policy Is defined In Runtime Manager as part of the API deployment to a Mule runtime, and then ONLY applied to the specific API Instance
