Mule-101 Exam Questions and Answers

QUESTION: 9

According to MuleSoft, which principle is common to both Service Oriented Architecture (SOA) and API-led connectivity approaches? 11

Service statefulness
Service reusability
Service centralization
Service interdependence

Answer(s): B

Explanation:

Comprehensive and Detailed Explanation;
The Shared Goal: Both SOA (an older architectural style) and API-led Connectivity (MuleSoft's modern approach) aim to solve the problem of "Spaghetti Code" by breaking monolithic applications into smaller pieces.
Reusability: The core promise of both is Reusability. SOA: Aimed to create reusable web services (often SOAP). API-led: Focuses on creating reusable Assets (System, Process, and Experience APIs) that can be discovered and self-served by other teams.
The Difference: While the goal (Reuse) is the same, SOA often failed due to heavy governance and lack of discoverability. API-led connectivity improves on this by emphasizing consumption and self- service via the Anypoint Exchange.

QUESTION: 10

A developer is examining the responses from a RESTful web service that is compliant with the Hypertext Transfer Protocol (HTTP/1.1) as defined by the Internet Engineering Task Force (IETF). 13 (The question asks to identify the code class for success)

5xx
2xx
4xx
3xx

Answer(s): B

Explanation:

Comprehensive and Detailed Explanation;
HTTP Status Codes: Understanding these is fundamental to MuleSoft integration. 2xx (Success - Answer B): The request was received, understood, and accepted. (e.g., 200 OK, 201

Created, 202 Accepted).
3xx (Redirection): Further action needs to be taken to complete the request (e.g., 301 Moved Permanently).
4xx (Client Error): The request contains bad syntax or cannot be fulfilled (e.g., 400 Bad Request, 401 Unauthorized, 404 Not Found).
5xx (Server Error): The server failed to fulfill an apparently valid request (e.g., 500 Internal Server Error, 502 Bad Gateway).
Context: When a Mule flow makes an HTTP Request, it checks these status codes to determine if the On Error scope should be triggered. By default, 4xx and 5xx trigger errors; 2xx indicates success.

QUESTION: 11

What is a defining characteristic of an Integration-Platform-as-a-Service (IPaaS)?

Code-first
Cloud-based
On-premises
No-code

Answer(s): B

Explanation:

Definition of iPaaS: Gartner and MuleSoft define iPaaS (Integration Platform as a Service) as a suite of cloud services enabling the development, execution, and governance of integration flows connecting any combination of on-premises and cloud-based processes, services, applications, and data within individual or across multiple organizations.
The Key Characteristic: The "as a Service" suffix explicitly denotes a Cloud-based delivery model111111111.
MuleSoft Context: CloudHub is the iPaaS component of the Anypoint Platform. It is a fully managed, multi-tenant, cloud-based integration platform where you deploy API implementations without managing the underlying hardware.

QUESTION: 12

An organization is not meeting its growth and innovation objectives because IT cannot deliver projects fast enough to keep up with the pace of change required by the business.

Adopt a new approach that decouples core IT projects from the innovation that happens within each line of business
Hire more IT developers, architects, and project managers to increase IT delivery
Modify IT governance and security controls so that line of business developers can have direct access to the organization's systems of record
Switch from a design-first to a code-first approach for IT development

Answer(s): A

Explanation:

The IT Delivery Gap: This question addresses the "IT Delivery Gap"--the widening gap between business demands and IT's capacity to deliver.
The Solution (New Operating Model): MuleSoft recommends shifting from a centralized factory model to an Asset-Based consumption model.
Decoupling (Option A): By using API-led Connectivity:
Central IT builds reusable System APIs (unlocking core assets/systems of record) and governs them. Lines of Business (LOB) consume these assets to build their own Process and Experience APIs (Innovation)2.
Why others fail:
(B) Hiring doesn't scale linearly with exponential demand. (C) Removing governance creates security risks ("Shadow IT"). (D) Code-first ignores reuse and leads to technical debt.

QUESTION: 13

Which component of Anypoint Platform belongs to the platform control plane?

Runtime Replica
Runtime Fabric
Anypoint Connectors
API Manager

Answer(s): D

Explanation:

Control Plane vs. Runtime Plane:
Control Plane: The set of components that manage, monitor, and design APIs and applications. This includes API Manager, Runtime Manager (the console), Anypoint Exchange, and Design Center3. Runtime Plane: The infrastructure where the applications actually run (execute). This includes the Mule Runtime engine, Runtime Fabric, and CloudHub workers. API Manager: It sits in the Control Plane and pushes policies (governance) down to the runtime engines (gateways).

QUESTION: 14

An API client makes an HTTP request to an API gateway with an Accept header containing the value "application/json".

status: healthy
{"status": "healthy"}
status>healthy</status>
status('healthy')

Answer(s): B

Explanation:

Content Negotiation: The HTTP Accept header is used by the client to tell the server what media type (format) it expects in the response4444.
application/json: This MIME type explicitly requests JSON (JavaScript Object Notation).
Analyzing the Options:
(B) {"status": "healthy"} is valid JSON format (Key-Value pair wrapped in braces).
(C) status>healthy</status> is XML.
(A) is YAML or Plain Text.

QUESTION: 15

An integration architect is designing an API that must accept requests from API clients for both XML and JSON content over HTTP/1.1 by default.

REST
GraphQL
gRPC
SOAP

Answer(s): A

Explanation:

REST (Representational State Transfer): REST is an architectural style that allows resources to be represented in multiple formats (Media Types)5555.

Versatility: Unlike SOAP (which is strictly XML), a RESTful API can easily support both JSON and XML representations of the same resource, often determined by the Accept or Content-Type headers.
Why others are incorrect:
SOAP: Strictly uses XML.
GraphQL: Typically uses JSON for both queries and responses. gRPC: Uses Protocol Buffers (binary), not human-readable JSON/XML by default.

QUESTION: 16

A system administrator needs to determine when permissions were last changed for an Anypoint

Platform user.

Audit Logging
Mule Stack Traces
Anypoint Monitoring
Anypoint Studio

Answer(s): A

Explanation:

Audit Logging: This feature in Anypoint Platform provides a searchable history of actions performed within the platform. It is designed specifically for governance and security compliance.
What it tracks: It records "who did what and when." This includes changes to:
User permissions and roles (Access Management).
Environment configurations.
API Manager policies.
Why others are incorrect:
Anypoint Monitoring: Focuses on application performance (CPU, Memory, API analytics), not administrative actions.
Stack Traces: Are used for debugging runtime application errors, not auditing user permissions.
