MuleSoft MCPA-Level-1 問題集

質問 1：
An API with multiple API implementations (Mule applications) is deployed to both CloudHub and customer- hosted Mule runtimes. All the deployments are managed by the MuleSoft-hosted control plane. An alert needs to be triggered whenever an API implementation stops responding to API requests, even if no API clients have called the API implementation for some time.
What is the most effective out-of-the-box solution to create these alerts to monitor the API implementations?
A. Handle API invocation exceptions within the calling API client and raise an alert from that API client when such an exception is thrown
B. Configure one Worker Not Responding alert.in Anypoint Runtime Manager for all API implementations that will then monitor every API implementation
C. Create monitors in Anypoint Functional Monitoring for the API implementations, where each monitor repeatedly invokes an API implementation endpoint
D. Add code to each API client to send an Anypoint Platform REST API request to generate a custom alert in Anypoint Platform when an API invocation times out

質問 2：
Which out-of-the-box key performance indicator measures the success of a typical Center for Enablement and is immediately available in responses from Anypoint Platform APIs?
A. Per published API, the number of developers that downloaded s version of the API specification
B. Per business group, the ratio of the number of production APT implementations deployed using a C1
/CD pipeline to the number of production API implementations deployed manually
C. Per published API, the number of consumers that requested access to the API and have been approved in the Production environment
D. Per deployed API implementation, the amount of bandwidth consumed each day

質問 3：
A developer from the Central IT team has created an initial version of the RAML definition in Design Center for an OAuth 2.0-protected System API and published it to Exchange. Another developer from LoB IT discovered the System API in Exchange and would like to leverage it in the Process API.
What is the MuleSoft-recommended approach for Process API to invoke the System API?
A. The Process API manually updates the Process API POM file to include the System API as a dependency
B. The Process APL uses the REST Connect Connector autogenerated in Exchange for the System API
C. The Process API uses property YAML files to store the System API URLs and uses the HTTP Request Connector to invoke the Systerm API
D. The Process API needs to import an CAuth 2.0 module from Exchange first and update it with OAuth
2.0 credentials before the System API can be invoked

質問 4：
What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, or the Mule Maven plugin?
A. Anypoint Platform APIs can ONLY automate interactions with CloudHub, while the Mule Maven plugin is required for deployment to customer-hosted Mule runtimes
B. API policies can be applied to the Anypoint Platform APIs so that ONLY certain LOBs have access to specific functions
C. By default, the Anypoint CLI and Mule Maven plugin are NOT included in the Mule runtime, so are NOT available to be used by deployed Mule applications
D. Access to Anypoint Platform APIs and Anypoint CU can be controlled separately through the roles and permissions in Anypoint Platform, so that specific users can get access to Anypoint CLI white others get access to the platform APIs

質問 5：
A company requires Mule applications deployed to CloudHub to be isolated between non-production and production environments. This is so Mule applications deployed to non-production environments can only access backend systems running in their customer-hosted non-production environment, and so Mule applications deployed to production environments can only access backend systems running in their customer- hosted production environment. How does MuleSoft recommend modifying Mule applications, configuring environments, or changing infrastructure to support this type of per-environment isolation between Mule applications and backend systems?
A. Create separate Anypoint VPCs for non-production and production environments, then configure connections to the backend systems in the corresponding customer-hosted environments
B. Modify properties of Mule applications deployed to the production Anypoint Platform environments to prevent access from non-production Mule applications
C. Configure firewall rules in the infrastructure inside each customer-hosted environment so that only IP addresses from the corresponding Anypoint Platform environments are allowed to communicate with corresponding backend systems
D. Create non-production and production environments in different Anypoint Platform business groups

C. API Consumer requests access to API >> API Client implementes logic to call an API >> API routes the request to >> API Implementation
D. API Client implementes logic to call an API >> API Consumer requests access to API >> API routes the request to >> API Implementation

質問 7：
How can the application of a rate limiting API policy be accurately reflected in the RAML definition of an API?
A. By refining the request definitions by adding a remaining Requests query parameter with description, type, and example
B. By refining the resource definitions by adding a description of the rate limiting policy behavior
C. By refining the response definitions by adding the x-ratelimit-* response headers with description, type, and example
D. By refining the response definitions by adding the out-of-the-box Anypoint Platform rate-limit- enforcement securityScheme with description, type, and example

質問 8：
Mule applications that implement a number of REST APIs are deployed to their own subnet that is inaccessible from outside the organization.
External business-partners need to access these APIs, which are only allowed to be invoked from a separate subnet dedicated to partners - called Partner-subnet. This subnet is accessible from the public internet, which allows these external partners to reach it.
Anypoint Platform and Mule runtimes are already deployed in Partner-subnet. These Mule runtimes can already access the APIs.
What is the most resource-efficient solution to comply with these requirements, while having the least impact on other applications that are currently using the APIs?
A. Implement (or generate) an API proxy Mule application for each of the APIs, then deploy the API proxies to the Mule runtimes
B. Duplicate the APIs as Mule applications, then deploy them to the Mule runtimes
C. Redeploy the API implementations to the same servers running the Mule runtimes
D. Add an additional endpoint to each API for partner-enablement consumption
正解：A

質問 9：
True or False. We should always make sure that the APIs being designed and developed are self-servable even if it needs more man-day effort and resources.
A. FALSE
B. TRUE
正解：B
