Questions for the MULE-101 were updated on : Dec 20 ,2025
According to MuleSoft, which major benefit does a Center for Enablement (C4E) provide for an
enterprise and its lines of business?
B
Explanation:
Center for Enablement (C4E): Unlike a Center of Excellence (CoE) which centralizes work, a C4E
focuses on enablement.
Self-Service: The primary goal is to harvest reusable assets and best practices so that the Lines of
Business (LOB) can build their own projects using these assets. This accelerates self-service and
removes Central IT as the bottleneck13.
Why others are incorrect:
Centralizing Project Management (D): C4E promotes decentralized delivery (federation), not
centralized management.
According to the Internet Engineering Task Force (IETF), which supporting protocol does File Transfer
Protocol (FTP) use for reliable communication?
B
Explanation:
TCP (Transmission Control Protocol): FTP is an application-layer protocol that relies on TCP at the
transport layer to ensure reliable, ordered, and error-checked delivery of a stream of bytes12.
Mechanism: FTP establishes two TCP connections: one for control (commands) and one for data
transfer.
Why others are incorrect:
UDP: Is unreliable (best effort).
HTTP: Is an alternative application protocol, not the transport layer for FTP.
LDAP: Is for directories.
According to MuleSoft's API development best practices, which type of API development approach
starts with writing and approving an API contract?
C
Explanation:
Design-First: This approach dictates that the API Contract (the Specification, e.g., RAML/OAS) must
be written, reviewed, and approved before any implementation code is written11.
The Contract: The "Contract" serves as the agreement between the API provider and the consumer.
Why others are incorrect:
Implement-first: You write the code (Mule flows) first, and the contract is generated from the code
(or ignored).
Catalyst: Is a broader delivery methodology, not specifically the "Contract-first" technical approach.
What is an example of data confidentiality?
A
Explanation:
Confidentiality: This security concept ensures that information is not made available or disclosed to
unauthorized individuals, entities, or processes.
Encryption (Option A): Transforming readable data (plaintext) into unreadable data (ciphertext) is the
primary technical control for confidentiality. 7If a file with PII is stolen but encrypted, the
confidentiality is maintained89.10
Why others are incorrect:
Signing (C): Ensures Integrity (proving the data hasn't changed), not confidentiality (the data is still
readable).
De-masking (B): Removes protection.
Providing Private Key (D): This is a severe security breach, not a protection mechanism.
Which Exchange asset type represents configuration modules that extend the functionality of an API
and enforce capabilities such as security?
C
Explanation:
Policies: In Anypoint Platform, a Policy is a configuration module that intercepts requests and
responses to enforce specific behaviors, such as security (OAuth, Basic Auth), traffic control (Rate
Limiting), or compliance6.
Exchange Asset: Policies (both out-of-the-box and custom policies built in XML) are stored as assets
in Anypoint Exchange.
Why others are incorrect:
Rulesets: Usually refer to API governance rules (linting RAML).
Connectors: Used to connect to external systems (Salesforce, DB), not to enforce security on the API
itself.
A team has completed the build and test activities for a Mule application that implements a System
API for its application network. Which Anypoint Platform component should the team now use to
both deploy and monitor the System API implementation?
B
Explanation:
Runtime Manager: This is the interface within the Anypoint Control Plane used to manage the
lifecycle of deployments5.
Capabilities:
Deploy: You upload the JAR file here to deploy it to CloudHub, Runtime Fabric, or On-Prem servers.
Monitor: Once deployed, it provides dashboards for CPU usage, Memory usage, and status
(Started/Stopped).
Why others are incorrect:
API Manager: Manages policies (security) and gateways, not the deployment of the application
artifact itself.
Design Center: For creating the app, not deploying it.
According to MuleSoft's recommended REST conventions, which HTTP method should an API use to
specify how API clients can request data from a specified resource?
A
Explanation:
HTTP GET: The GET method is used to retrieve (read) a representation of a resource4. It is safe and
idempotent, meaning it does not alter the state of the server.
Usage: If you want to "request data" (e.g., Get Customer Details), GET is the standard method.
Why others are incorrect:
POST: Used to create a new resource.
PUT: Used to replace (update) an entire resource.
PATCH: Used to partially update a resource.
An integration team uses Anypoint Platform and follows MuleSoft's recommended approach to full
lifecycle API development. Which step should the team's API designer take before the API developers
implement the API specification?
A
Explanation:
Design-First Feedback Loop: In the MuleSoft API Lifecycle, after designing the API specification
(RAML/OAS) in Design Center, the critical next step is to Publish to Exchange3.
Mocking & Validation: Once in Exchange, the API creates a "Mocking Service." This allows potential
consumers (frontend devs, mobile devs) to make test calls against the design before any backend
code is written.
Purpose: This solicits feedback to ensure the design meets business needs. If changes are needed,
they are made to the spec cheap and fast, rather than rewriting complex code later (Implementation
phase).
An IT integration delivery team begins a project by gathering all of the requirements, and proceeds
to execute the remaining project activities as sequential, non-repeating phases. Which IT project
delivery methodology is this team following?
C
Explanation:
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.
Refer to the exhibit. What is the type of data format shown in the exhibit?
YAML
text
traits:
error-responses: traits/error-responses.raml
jwt-required:
headers:
x-jwt:
type: string
description: JWT token string
C
Explanation:
YAML (YAML Ain't Markup Language): The snippet provided uses indentation (whitespace) to denote
structure and colons to separate keys from values. This is the signature syntax of YAML.
RAML Context: MuleSoft's RAML (RESTful API Modeling Language) is built on top of YAML1.
Therefore, any RAML specification is technically a YAML file.
Why others are incorrect:
JSON: Uses curly braces {} and quotes "" strictly.
XML: Uses angle brackets <tag></tag>.
CSV: Uses comma-separated values.
According to MuleSoft, what action should an IT organization take regarding its technology assets in
order to close the IT delivery gap?
B
Explanation:
The Key to Speed: You cannot close the delivery gap by working harder (hiring more staff) or by
creating custom code for every project (custom assets). You must leverage Reuse.
Discoverability is Critical: Reuse is impossible if developers don't know that an asset exists.
Anypoint Exchange: By publishing assets (APIs, connectors, fragments) to a central repository
(Exchange) and making them searchable and documented, organizations enable "Self-Service."
Developers can find what they need instantly, drastically reducing the time to deliver new projects.
What is an ad8vantage that Anypoint Platf9orm offers by providing universal API management and
Integration-Platform-as-a-Service (iPaaS) capabilities in a unified platform?
D
Explanation:
Unified Platform: Many vendors offer either API Management (APIM) or Integration (iPaaS) as
separate tools. Anypoint Platform combines them.
Single Control Plane: The primary advantage is having a single interface (The Anypoint Control Plane)
where you can do everything: design APIs, build integrations, deploy them, govern them with
policies, and monitor them.
Impact: This reduces complexity, lowers costs (no need to buy two separate stacks), and streamlines
the workflow from development to operations.
Which type of communication is managed by a service mesh in a microservices architecture?
C
Explanation:
Service Mesh Definition: A service mesh is a dedicated infrastructure layer for handling service-to-
service communication.
East-West Traffic: It is specifically designed to manage East-West traffic, which is the network traffic
flowing inside the data center or cluster between different microservices.
Capabilities: It handles things like mutual TLS (mTLS) for security, retries, load balancing, and traffic
control between these services without requiring changes to the application code itself.
A DevOps team has adequate observability of individual system behavior and performance, but it
struggles to track the entire lifecycle of each request across different microservices. Which additional
observability approach should this team consider adopting?
D
Explanation:
The Challenge: In a microservices architecture, a single user request might traverse dozens of
different services. If an error occurs or latency is high, looking at the logs of just one service isn't
enough.
Distributed Tracing: This is the specific technology used to track a request as it hops between
services.
How it works: It assigns a unique Trace ID (Correlation ID) to the request at the entry point. This ID is
passed to every downstream service. Tracing tools (like Anypoint Monitoring's Telemetry or Jaeger)
verify the full path, showing exactly how long the request spent in each hop.
According to MuleSoft's IT delivery and operating model, which approach can an organization adopt
in order to reduce the frequency of IT project delivery failures?
C
Explanation:
The Problem (IT Delivery Gap): Traditional IT operating models often treat IT as a centralized factory,
which becomes a bottleneck. The business demands change faster than Central IT can deliver,
leading to project failures or delays.
The Solution (Decoupling): MuleSoft advocates for a new operating model (C4E) where Central IT
produces reusable assets (System APIs) and then "gets out of the way."
Innovation at the Edge: By decoupling core IT from the Line of Business (LOB), the LOB developers
can self-serve those assets to build their own Process and Experience APIs. This allows innovation to
happen in parallel across the organization, rather than waiting in a single queue, thus reducing failure
rates associated with bottlenecks. 1111
