Free Practice Questions for Salesforce Mule-101 Exam

Waterfall Methodology:This traditional approach is characterized by a linear, sequential design process2.

Key Characteristics:

Upfront Requirements:All requirements are gathered at the very beginning (as stated in the question).

Sequential Phases:Analysis -> Design -> Implementation -> Testing -> Deployment.

Non-repeating:You typically do not go back to a previous phase once it is signed off.

Why others are incorrect:Agile, Scrum, and Kanban are iterative methodologies that encourage repeating cycles (sprints) and evolving requirements, which is the opposite of the scenario described.

Automatic API Proxy Generation:When managing an API inAPI Manager, Anypoint Platform allows you to automatically generate and deploy an API Proxy application to CloudHub.

Functionality:This proxy sits in front of your backend implementation (or a non-Mule API) and enforces policies (like rate limiting or security) without requiring you to write code for the proxy manually. This significantly speeds up the process of securing and managing APIs compared to building custom gateway solutions.

Customer Relationship Management (CRM):A CRM system (like Salesforce) is specifically designed to manage a company's interactions with current and potential customers5.

Key Functionality:It stores contact information, identifies sales opportunities, records service issues, and manages marketing campaigns—perfectly matching the requirement to "increase cross-selling" and "track prospect data"6.

Why others are incorrect:

SCM:Manages the flow of goods and services (logistics/inventory)7.

ITSM:Manages IT services (help desk tickets)8.

B2B:Refers to the exchange of products/services between businesses, not the system of record for prospect data9.

Correction Note:The provided PDF Answer Key listsBas the answer. However, based on standard MuleSoft and REST architecture principles,Ais the correct logical flow.

The Concept:In an API-led connectivity approach, the "Interface" represents the contract (such as the RAML specification, the HTTP Listener, and the APIkit Router). The "Implementation" represents the backend logic and flows that process the request.

The Flow:

API Client:The consumer (e.g., a mobile app, Postman, or another system) initiates the HTTP request.

API Interface:The request first hits the Interface. This layer defines the URL, validates the request against the API Specification (RAML/OAS), and routes it to the correct flow.

API Implementation:Once validated and routed, the request is processed by the implementation flows (business logic) to fetch data or perform actions.

Therefore, the data travels:Client -> Interface -> Implementation.

Comprehensive and Detailed Explanation:

Request-Response:TheHTTP protocolis inherently synchronous and follows the Request-Response pattern. The client sends a request (the GET command) andwaitsfor the server to process the query and send back the data (the 200 OK response).

Synchronous Nature:The "Synchronous" keyword in the question is the biggest clue. The client processing is blocked or expects an immediate return of data before proceeding.

Why "Multicast" is incorrect:Multicast is aone-to-manypattern (usually asynchronous). It involves sending one message to multiple receivers (like a topic subscription), which contradicts the question's scenario of getting a "record from asinglesystem."8

REST APIs (Asset Type):In Anypoint Exchange and Design Center, when you create a new project to define a full API specification (using RAML or OAS), the resulting asset type is categorized as a "REST API."

API Spec Fragments:These arepartsof a specification (like a specific Data Type, Trait, or Security Scheme) designed to be reused across multiple different API specs. They are not "complete" APIs on their own.

SOAP APIs:Use WSDL (XML), not RAML/OAS.
