質問 1：
Which of the following best fits the definition of API-led connectivity?
A. API-led connectivity is a technology which enabled us to implement Experience, Process and System layer based APIs
B. API-led connectivity is a 3-layered architecture covering Experience, Process and System layers

質問 3：
When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?
A. The number of DNS entries allocated to the API implementation
B. The assignment of each HTTP request to a particular CloudHub worker
C. The SSL certificates used by the API implementation to expose HTTPS endpoints
D. The logging configuration that enables log entries to be visible in Runtime Manager

質問 4：
An organization has created an API-led architecture that uses various API layers to integrate mobile clients with a backend system. The backend system consists of a number of specialized components and can be accessed via a REST API. The process and experience APIs share the same bounded-context model that is different from the backend data model. What additional canonical models, bounded-context models, or anti-corruption layers are best added to this architecture to help process data consumed from the backend system?
A. Create a canonical model that combines the backend and API-led models to simplify and unify data models, and minimize data transformations.
B. Create an anti-corruption layer for every API to perform transformation for every data model to match each other, and let data simply travel between APIs to avoid the complexity and overhead of building canonical models
C. Create a bounded-context model for the system layer to closely match the backend data model, and add an anti-corruption layer to let the different bounded contexts cooperate across the system and process layers
D. Create a bounded-context model for every layer and overlap them when the boundary contexts overlap, letting API developers know about the differences between upstream and downstream data models

質問 5：
An API implementation is updated. When must the RAML definition of the API also be updated?
A. When the API implementation changes the structure of the request or response messages
B. When the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system
C. When the API implementation is migrated from an older to a newer version of the Mule runtime
D. When the API implementation is optimized to improve its average response time

質問 6：
When could the API data model of a System API reasonably mimic the data model exposed by the corresponding backend system, with minimal improvements over the backend system's data model?
A. When the System API can be assigned to a bounded context with a corresponding data model
B. When a pragmatic approach with only limited isolation from the backend system is deemed appropriate
C. When there is an existing Enterprise Data Model widely used across the organization
D. When the corresponding backend system is expected to be replaced in the near future

質問 7：
A retail company with thousands of stores has an API to receive data about purchases and insert it into a single database. Each individual store sends a batch of purchase data to the API about every 30 minutes. The API implementation uses a database bulk insert command to submit all the purchase data to a database using a custom JDBC driver provided by a data analytics solution provider. The API implementation is deployed to a single CloudHub worker. The JDBC driver processes the data into a set of several temporary disk files on the CloudHub worker, and then the data is sent to an analytics engine using a proprietary protocol. This process usually takes less than a few minutes. Sometimes a request fails. In this case, the logs show a message from the JDBC driver indicating an out-of-file-space message. When the request is resubmitted, it is successful.
What is the best way to try to resolve this throughput issue?
A. Increase the number of CloudHub workers
B. se a CloudHub autoscaling policy to add CloudHub workers
C. Increase the size of the CloudHub worker(s)
D. Use a CloudHub autoscaling policy to increase the size of the CloudHub worker
正解：A

質問 8：
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

質問 9：
Refer to the exhibit.

what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?
A. The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes
B. Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications
C. Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure
D. API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane
