Good MCPA-Level 1 Maintenance Exam Questions Help You Prepare Well

1. Refer to the exhibit.





An organization uses one specific CloudHub (AWS) region for all CloudHub deployments.

How are CloudHub workers assigned to availability zones (AZs) when the organization's Mule applications are deployed to CloudHub in that region?

2. A set of tests must be performed prior to deploying API implementations to a staging environment. Due to data security and access restrictions, untested APIs cannot be granted access to the backend systems, so instead mocked data must be used for these tests. The amount of available mocked data and its contents is sufficient to entirely test the API implementations with no active connections to the backend systems.

What type of tests should be used to incorporate this mocked data?

3. An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft).

What best describes each modern API in relation to this new IT operating model?

4. What CANNOT be effectively enforced using an API policy in Anypoint Platform?

5. What is the main change to the IT operating model that MuleSoft recommends to organizations to improve innovation and clock speed?

6. Refer to the exhibit.





what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

7. Refer to the exhibit.





Three business processes need to be implemented, and the implementations need to communicate with several different SaaS applications.

These processes are owned by separate (siloed) LOBs and are mainly independent of each other, but do share a few business entities. Each LOB has one development team and their own budget

In this organizational context, what is the most effective approach to choose the API data models for the APIs that will implement these business processes with minimal redundancy of the data models?

A) Build several Bounded Context Data Models that align with coherent parts of the business processes and the definitions of associated business entities





B) Build distinct data models for each API to follow established micro-services and Agile API-centric practices





C) Build all API data models using XML schema to drive consistency and reuse across the organization





D) Build one centralized Canonical Data Model (Enterprise Data Model) that unifies all the data types from all three business processes, ensuring the data model is consistent and non-redundant

8. An organization is deploying their new implementation of the OrderStatus System API to multiple workers in CloudHub. This API fronts the organization's on-premises Order Management System, which is accessed by the API implementation over an IPsec tunnel.

What type of error typically does NOT result in a service outage of the OrderStatus System API?

9. 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?

10. 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?

11. 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 API's public portal.

The API endpoint does NOT change in the new version.

How should the developer of an API client respond to this change?

12. What are 4 important Platform Capabilities offered by Anypoint Platform?

13. Refer to the exhibit.





What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?

A) Handle customizations for the end-user application at the Process API level rather than the Experience API level





B) Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs





C) Always use a tiered approach by creating exactly one API for each of the 3 layers (Experience, Process and System APIs)





D) Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs

14. What is true about automating interactions with Anypoint Platform using tools such as Anypoint Platform REST APIs, Anypoint CU, or the Mule Maven plugin?

15. A retail company is using an Order API to accept new orders. The Order API uses a JMS queue to submit orders to a backend order management service. The normal load for orders is being handled using two (2) CloudHub workers, each configured with 0.2 vCore. The CPU load of each CloudHub worker normally runs well below 70%. However, several times during the year the Order API gets four times (4x) the average number of orders. This causes the CloudHub worker CPU load to exceed 90% and the order submission time to exceed 30 seconds. The cause, however, is NOT the backend order management service, which still responds fast enough to meet the response SLA for the Order API.

What is the MOST resource-efficient way to configure the Mule application's CloudHub deployment to help the company cope with this performance challenge?

16. Which layer in the API-led connectivity focuses on unlocking key systems, legacy systems, data sources etc and exposes the functionality?

17. What is the most performant out-of-the-box solution in Anypoint Platform to track transaction state in an asynchronously executing long-running process implemented as a Mule application deployed to multiple CloudHub workers?

18. 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.

19. What Mule application can have API policies applied by

Anypoint Platform to the endpoint exposed by that Mule application?

A) A Mule application that accepts requests over HTTP/1.x





B) A Mule application that accepts JSON requests over TCP but is NOT required to provide a response





C) A Mute application that accepts JSON requests over WebSocket





D) A Mule application that accepts gRPC requests over HTTP/2

20. 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?

21. Question 10: Skipped

An API implementation returns three X-RateLimit-* HTTP response headers to a requesting API client.

What type of information do these response headers indicate to the API client?

22. A System API is designed to retrieve data from a backend system that has scalability challenges.

What API policy can best safeguard the backend system?

23. What is typically NOT a function of the APIs created within the framework called API-led connectivity?

24. Traffic is routed through an API proxy to an API implementation. The API proxy is managed by API Manager and the API implementation is deployed to a CloudHub VPC using Runtime Manager. API policies have been applied to this API.

In this deployment scenario, at what point are the API policies enforced on incoming API client requests?

25. When using CloudHub with the Shared Load Balancer, what is managed EXCLUSIVELY by the API implementation (the Mule application) and NOT by Anypoint Platform?

26. The application network is recomposable: it is built for change because it "bends but does not break"

27. What is a best practice when building System APIs?

28. 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?

29. A new upstream API Is being designed to offer an SLA of 500 ms median and 800 ms maximum (99th percentile) response time. The corresponding API implementation needs to sequentially invoke 3 downstream APIs of very similar complexity.

The first of these downstream APIs offers the following SLA for its response time: median:

100 ms, 80th percentile: 500 ms, 95th percentile: 1000 ms.

If possible, how can a timeout be set in the upstream API for the invocation of the first downstream API to meet the new upstream API's desired SLA?

30. How can the application of a rate limiting API policy be accurately reflected in the RAML definition of an API?

31. An API experiences a high rate of client requests (TPS) vwth small message paytoads.

How can usage limits be imposed on the API based on the type of client application?
