MCPA-LEVEL1 Online Practice Questions and Answers

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. Enable mocking services for each of the relevant APIs and expose them via their Anypoint Exchange entry

B. Ensure the APIs are well documented through their Anypoint Exchange entries and API Consoles and share these pages with all API consumers

C. Create API Notebooks and include them in the relevant Anypoint Exchange entries

D. Make relevant APIs discoverable via an Anypoint Exchange entry

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, and ONLY use the first response

B. 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

C. Invoke the system API deployed to the primary environment, and if it fails, invoke the system API deployed to the DR environment

D. Invoke ONLY the system API deployed to the primary environment, and add timeout and retry logic to avoid intermittent failures

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 producer should be requested to run the old version in parallel with the new one

B. The API producer should be contacted to understand the change to existing functionality

C. The API client code only needs to be changed if it needs to take advantage of the new features

D. The API clients need to update the code on their side and need to do full regression

Refer to the exhibit.

A developer is building a client application to invoke an API deployed to the STAGING environment that is governed by a client ID enforcement policy.

What is required to successfully invoke the API?

A. The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment

B. The client ID and secret for the Anypoint Platform account's STAGING environment

C. The client ID and secret obtained from Anypoint Exchange for the API instance in the STAGING environment

D. A valid OAuth token obtained from Anypoint Platform and its associated client ID and secret

What best explains the use of auto-discovery in API implementations?

A. It makes API Manager aware of API implementations and hence enables it to enforce policies

B. It enables Anypoint Studio to discover API definitions configured in Anypoint Platform

C. It enables Anypoint Exchange to discover assets and makes them available for reuse

D. It enables Anypoint Analytics to gain insight into the usage of APIs

When must an API implementation be deployed to an Anypoint VPC?

A. When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance

B. When the API implementation must be accessible within a subnet of a restricted customer-hosted network that does not allow public access

C. When the API implementation must be deployed to a production AWS VPC using the Mule Maven plugin

D. When the API Implementation must write to a persistent Object Store

What Anypoint Connectors support transactions?

A. Database, JMS, VM

B. Database, 3MS, HTTP

C. Database, JMS, VM, SFTP

D. Database, VM, File

What correctly characterizes unit tests of Mule applications?

A. They test the validity of input and output of source and target systems

B. They must be run in a unit testing environment with dedicated Mule runtimes for the environment

C. They must be triggered by an external client tool or event source

D. They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity

An organization wants to make sure only known partners can invoke the organization's APIs. To achieve this security goal, the organization wants to enforce a Client ID Enforcement policy in API Manager so that only registered partner applications can invoke the organization's APIs. In what type of API implementation does MuleSoft recommend adding an API proxy to enforce the Client ID Enforcement policy, rather than embedding the policy directly in the application's JVM?

A. A Mule 3 application using APIkit

B. A Mule 3 or Mule 4 application modified with custom Java code

C. A Mule 4 application with an API specification

D. A Non-Mule application

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

A. They provide an additional layer of resilience on top of the underlying backend system, thereby insulating clients from extended failure of these systems.

B. 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.

C. They reduce the dependency on the underlying backend systems by helping unlock data from backend systems In a reusable and consumable way.

D. They can compose data from various sources and combine them with orchestration logic to create higher level value.
