MuleSoft MCPA-Level-1 問題集

質問 1：
A Platform Architect inherits a legacy monolithic SOAP-based web service that performs a number of tasks, including showing all policies belonging to a client. The service connects to two back-end systems - a life- insurance administration system and a general-insurance administration system - and then queries for insurance policy information within each system, aggregates the results, and presents a SOAP-based response to a user interface (UI).
The architect wants to break up the monolithic web service to follow API-led conventions.
Which part of the service should be put into the process layer?
A. Querying the data from the administration systems
B. Authenticating and maintaining connections to each of the back-end administration systems
C. Presenting the SOAP-based response to the UI
D. Combining the insurance policy information from the administration systems

質問 2：
Version 3.0.1 of a REST API implementation represents time values in PST time using ISO 8601 hh:mm:ss format. The API implementation needs to be changed to instead represent time values in CEST time using ISO 8601 hh:mm:ss format. When following the semver.org semantic versioning specification, what version should be assigned to the updated API implementation?
A. 4.0.0
B. 3.1.0
C. 3.0.1
D. 3.0.2

質問 3：
The implementation of a Process API must change.
What is a valid approach that minimizes the impact of this change on API clients?
A. Implement the Process API changes in a new API implementation, and have the old API implementation return an HTTP status code 301 - Moved Permanently to inform API clients they should be calling the new API implementation
B. Postpone changes until API consumers acknowledge they are ready to migrate to a new Process API or API version
C. Implement required changes to the Process API implementation so that whenever possible, the Process API's RAML definition remains unchanged
D. Update the RAML definition of the current Process API and notify API client developers by sending them links to the updated RAML definition

質問 4：
What best explains the use of auto-discovery in API implementations?
A. It enables Anypoint Studio to discover API definitions configured in Anypoint Platform
B. It enables Anypoint Analytics to gain insight into the usage of APIs
C. It enables Anypoint Exchange to discover assets and makes them available for reuse
D. It makes API Manager aware of API implementations and hence enables it to enforce policies

質問 5：
What is a key performance indicator (KPI) that measures the success of a typical C4E that is immediately apparent in responses from the Anypoint Platform APIs?
A. The number of production outage incidents reported in the last 24 hours
B. The fraction of API implementations deployed manually relative to those deployed using a CI/CD tool
C. The number of API implementations that have a publicly accessible HTTP endpoint and are being managed by Anypoint Platform
D. The number of API specifications in RAML or OAS format published to Anypoint Exchange

質問 6：
A large company wants to implement IT infrastructure in its own data center, based on the corporate IT policy requirements that data and metadata reside locally.
Which combination of Mule control plane and Mule runtime plane(s) meets the requirements?
A. Anypoint Platform Private Cloud Edition for the control plane and customer-hosted Mule runtimes for the runtime plane
B. The MuleSoft-hosted control plane and Anypoint Runtime Fabric for the runtime plane
C. Anypoint Platform Private Cloud Edition for the control plane and the MuleSoft-hosted runtime plane
D. The MuleSoft-hosted control plane and customer-hosted Mule runtimes for the runtime plane

質問 7：
Refer to the exhibit.

A RAML definition has been proposed for a new Promotions Process API, and has been published to Anypoint Exchange.
The Marketing Department, who will be an important consumer of the Promotions API, has important requirements and expectations that must be met.
What is the most effective way to use Anypoint Platform features to involve the Marketing Department in this early API design phase?
A) Ask the Marketing Department to interact with a mocking implementation of the API using the automatically generated API Console

B) Organize a design workshop with the DBAs of the Marketing Department in which the database schema of the Marketing IT systems is translated into RAML C) Use Anypoint Studio to Implement the API as a Mule application, then deploy that API implementation to CloudHub and ask the Marketing Department to interact with it D) Export an integration test suite from API designer and have the Marketing Department execute the tests In that suite to ensure they pass

質問 9：
A system API has a guaranteed SLA of 100 ms per request. The system API is deployed to a primary environment as well as to a disaster recovery (DR) environment, with different DNS names in each environment. An upstream process API invokes the system API and the main goal of this process API is to respond to client requests in the least possible time. In what order should the system APIs be invoked, and what changes should be made in order to speed up the response time for requests from the process API?
A. In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment using a scatter-gather configured with a timeout, and then merge the responses
B. Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures
C. Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment
D. In parallel, invoke the system API deployed to the primary environment and the system API deployed to the DR environment, and ONLY use the first response
