MuleSoft Integration Foundations Practice Exam 2025: Latest Questions

An API team is reviewing a new integration project. Which statement best describes what an API specification (for example, RAML or OAS) is used for?

A company wants to expose data from multiple back-end systems through a single, consistent interface for mobile and web apps. Which API-led connectivity layer is primarily responsible for orchestrating and composing data from multiple systems for a specific business process?

A developer wants to publish an API for discovery and reuse across teams, including documentation and versioned assets. Which MuleSoft component is designed for this purpose?

An integration must send a request to a downstream system and wait for an immediate response within the same user interaction. Which integration style is most appropriate?

An API is placed behind Anypoint API Manager policies, but consumers report inconsistent access when calling it. The API is deployed to Mule runtime, and the team suspects the API instance is not being correctly tracked by the platform. What is the most likely missing step?

A team needs to integrate Salesforce with an ERP system. The ERP can only handle 50 requests per second, but Salesforce events can spike far above that rate. Which approach best helps protect the ERP from bursts while still processing all events?

A company is building a reusable integration layer. Multiple channels (mobile app, partner portal, internal web app) need different shapes of the same customer data, but all data ultimately comes from the same CRM. Which API-led approach is the best fit?

A Mule application processes incoming orders and occasionally fails when calling a downstream inventory service. The business requires that failed orders be retried a few times and then sent to a separate handling path for manual review without blocking other orders. Which design best meets this requirement?

A team plans to deploy the same Mule application to dev, test, and prod. They want to avoid hardcoding environment-specific values like endpoints and credentials and follow best practices for configuration management. What is the recommended approach?

A company wants to implement an enterprise integration strategy that maximizes reuse, reduces point-to-point dependencies, and supports independent evolution of systems and consumer experiences. Which architectural approach best aligns with these goals?

An operations team wants a central location to discover, document, and reuse APIs across multiple projects. Which MuleSoft component best supports this need?

A team is choosing between orchestration and choreography for a new integration. They want a single integration layer to coordinate calls to multiple systems and enforce consistent error handling. Which approach best fits?

A client application calls a REST API and receives an HTTP 401 response. What is the most likely meaning of this status code?

A retailer wants to implement API-led connectivity for order processing. They need a stable API that represents core business objects (Orders, Customers) and can be reused by multiple channels. Which API layer is the best fit?

A team is designing an API contract and wants strong, standardized documentation, data types, and examples to align developers and consumers. Which artifact is typically used for this in MuleSoft?

A Mule application deployed to CloudHub is intermittently failing during peak traffic due to limited capacity. The team wants to improve performance without changing application logic. What is the most appropriate first step?

A Mule flow calls three downstream systems. If any system is slow, the overall response time becomes unacceptable. Which integration approach best reduces user-perceived latency by decoupling the request from downstream processing?

A developer is troubleshooting a Mule flow where a DataWeave transformation fails at runtime due to unexpected input structure. What is the best tool/feature to inspect the payload at each step during debugging?

A company wants to apply an API policy so that only approved client applications can call an API, using a client ID and client secret. Which policy most directly supports this requirement?

A Mule application processes customer updates. If the same message is delivered twice, it must not create duplicate updates in the target system. Which design principle/pattern best addresses this requirement?

A team wants to enforce consistent, reusable security policies (for example, client ID enforcement, rate limiting, and IP allowlisting) across multiple APIs without changing each API implementation. Which MuleSoft capability should they use?

A retail company needs to notify multiple downstream systems (inventory, shipping, and analytics) whenever an order is placed. The downstream systems can process the event asynchronously, and the order system must not be slowed down by each consumer. Which integration approach best fits this requirement?

A Mule application is deployed to CloudHub and begins failing only under higher load. Logs show intermittent connection failures to a backend database. Which action is most likely to improve reliability without changing business logic?

An organization follows API-led connectivity and is building a new Process API that combines customer data from Salesforce and an on-prem ERP System API. The Process API must provide a consistent canonical customer representation even if either source changes its field names. Where should the transformation to the canonical model primarily occur?

A developer reports that API consumers receive HTTP 404 errors when calling an API that is deployed and running. The Mule app includes an HTTP Listener and flows appear started. Which is the most likely cause to check first?
