A retailer is designing a data exchange interface to be used by its suppliers. The interface must support secure communication over the public internet. The interface must also work with a wide variety of programming languages and IT systems used by suppliers.
What are suitable interface technologies for this data exchange that are secure, cross-platform, and internet friendly, assuming that Anypoint Connectors exist for these interface technologies?
A. EDJFACT XML over SFTP JSON/REST over HTTPS
B. SOAP over HTTPS HOP over TLS gRPC over HTTPS
C. XML over ActiveMQ XML over SFTP XML/REST over HTTPS
D. CSV over FTP YAML over TLS JSON over HTTPS
Explanation
* As per definition of API by Mulesoft , it is Application Programming Interface using HTTP-based protocols. Non-HTTP-based programmatic interfaces are not APIs.
* HTTP-based programmatic interfaces are APIs even if they don’t use REST or JSON. Hence implementation based on Java RMI, CORBA/IIOP, raw TCP/IP interfaces are not API's as they are not using HTTP.
* One more thing to note is FTP was not built to be secure. It is generally considered to be an insecure protocol because it relies on clear-text usernames and passwords for authentication and does not use encryption.
* Data sent via FTP is vulnerable to sniffing, spoofing, and brute force attacks, among other basic attack methods.
Considering the above points only correct option is
-XML over ActiveMQ
- XML over SFTP
- XML/REST over HTTPS
An organization has just developed a Mule application that implements a REST API. The mule application will be deployed to a cluster of customer hosted Mule runtimes. What additional infrastructure component must the customer provide in order to distribute inbound API requests across the Mule runtimes of the cluster?
A. A message broker
B. An HTTP Load Balancer
C. A database
D. An Object Store
Explanation
Correct answer is An HTTP Load Balancer.
Key thing to note here is that we are deploying application to customer hosted Mule runtime. This means we will need load balancer to route the requests to different instances of the cluster.
Rest all options are distractors and their requirement depends on project use case.
What limits if a particular Anypoint Platform user can discover an asset in Anypoint Exchange?
A. Design Center and RAML were both used to create the asset
B. The existence of a public Anypoint Exchange portal to which the asset has been published
C. The type of the asset in Anypoint Exchange
D. The business groups to which the user belongs
Explanation
* "The existence of a public Anypoint Exchange portal to which the asset has been published" - question does not mention anything about the public portal. Beside the public portal is open to the internet, to anyone. * If you cannot find an asset in the current business group scopes, search in other scopes. In the left navigation bar click All assets (assets provided by MuleSoft and your own master organization), Provided by MuleSoft, or a business group scope. User belonging to one Business Group can see assets related to his group only Reference:

Correct answer is The business groups to which the user belongs
A mule application is being designed to perform product orchestration. The Mule application needs to join together the responses from an inventory API and a Product Sales History API with the least latency. To minimize the overall latency. What is the most idiomatic (used for its intended purpose) design to call each API request in the Mule application?
A. Call each API request in a separate lookup call from Dataweave reduce operator
B. Call each API request in a separate route of a Scatter-Gather
C. Call each API request in a separate route of a Parallel For Each scope
D. Call each API request in a separate Async scope
Explanation:
Scatter-Gather sends a request message to multiple targets concurrently. It collects the responses from all routes, and aggregates them into a single message.

An organization is building out a test suite for their application using MUnit. The Integration Architect has recommended using Test Recorder in Anypoint Studio to record the processing flows and then configure unit tests based on the captured events. What Is a core consideration that must be kept In mind while using Test Recorder?
A. The Recorder supports loops where the structure of the data being tested changes inside the Iteration
B. Mocking values resulting from parallel processes are possible and will not affect theexecution of the processors that follow in the test
C. The Recorder supports mocking a message before or inside a Foreach processor
D. Tests for flows cannot be created if Mule errors are raised Inside the flows, even if the errors are handled by On-Error Continue error handlers

A project team uses RAML specifications to document API functional requirements and deliver API definitions. As per the current legal requirement, all designed API definitions to be augmented with an additional non-functional requirement to protect the services from a high rate of requests according to define service level agreements. Assuming that the project is following Mulesoft API governance and policies, how should the project team convey the necessary non-functional requirement to stakeholders?
A. Create proxies in API manager for the non functional requirement and publish to exchange
B. Add all non functional requirements as comments to RAML specification and publish to exchange
C. Create various SLA's in API manager for the non functional requirement and publish to exchange
D. Update API definitions with the fragment for the appropriate policy and publish to exchange
Explanation:
To ensure that non-functional requirements, such as rate limiting, are clearly communicated and enforced in the designed API definitions, the project team should use API fragments for the appropriate policy. Here's why option D is correct:
API Governance and Policies: Mulesoft's API governance framework allows the definition and enforcement of policies across APIs to ensure consistency and compliance with organizational standards. These policies can include security, rate limiting, logging, and more.
Policy Fragments: By updating API definitions with policy fragments, the team can encapsulate the non-functional requirements within the API specification itself. This approach ensures that these requirements are an integral part of the API design and are automatically applied whenever the API is deployed.
Publishing to Exchange: Publishing the updated API definitions with the policy fragments to Anypoint Exchange makes them available for reuse and ensures that all stakeholders have access to the latest, compliant API specifications.
Example of adding a rate limiting policy fragment to a RAML file:
#%RAML 1.0 title: Example API version: v1 baseUri: https://api.example.com/v1 ... /* Include the rate limiting policy fragment */ uses: rateLimitPolicy: !include rate-limit-policy.raml
The rate-limit-policy.raml fragment might define the specific rate limiting rules as per the service level agreements.

An architect is designing a Mule application to meet the following two requirements:
1. The application must process files asynchronously and reliably from an FTPS server to a back-end database using VM intermediary queues for
load-balancing Mule events.
2. The application must process a medium rate of records from a source to a target system using a Batch Job scope.
To make the Mule application more reliable, the Mule application will be deployed to two CloudHub 1.0 workers.
Following MuleSoft-recommended best practices, how should the Mule application deployment typically be configured in Runtime Manger to best
support the performance and reliability goals of both the Batch Job scope and the file processing VM queues?
A. Check the Persistent VM queues checkbox in the application deployment configuration
B. Check the Non-persistent VM queues checkbox in the application deployment configuration
C. In the Runtime Manager Properties tab, disable persistent VM queues for Batch Job scopes
D. In the Runtime Manager Properties tab, enable persistent VM queues for the FTPS connector

An organization designing a hybrid, load balanced, single cluster production environment. Due to performance service level agreement goals, it is looking into running the Mule applications in an active-active multi node cluster configuration. What should be considered when running its Mule applications in this type of environment?
A. All event sources, regardless of time , can be configured as the target source by the primary node in the cluster
B. An external load balancer is required to distribute incoming requests throughout the cluster nodes
C. A Mule application deployed to multiple nodes runs in an isolation from the other nodes in the cluster
D. Although the cluster environment is fully installed configured and running, it will not process any requests until an outage condition is detected by the primary node in the cluster.
Explanation:
In a hybrid, load-balanced, single cluster production environment running Mule applications in an active-active multi-node configuration, several considerations are critical for ensuring performance and reliability. The key consideration is the use of an external load balancer:

An application load balancer routes requests to a RESTful web API secured by Anypoint Flex Gateway. Which protocol is involved in the communication between the load balancer and the Gateway?
A. SFTP
B. HTTPS
C. LDAP
D. SMTP
Explanation:
An application load balancer routes requests to a RESTful web API secured by Anypoint Flex Gateway using the HTTPS protocol. HTTPS (HyperText Transfer Protocol Secure) ensures that the communication between the load balancer and the gateway is encrypted and secure, protecting the data from eavesdropping and tampering. HTTPS is the standard protocol for secure communication over the internet, especially for APIs handling sensitive data.

A set of integration Mule applications, some of which expose APIs, are being created to enable a new business process. Various stakeholders may be impacted by this. These stakeholders are a combination of semi-technical users (who understand basic integration terminology and concepts such as JSON and XML) and technically skilled potential consumers of the Mule applications and APIs. What Is an effective way for the project team responsible for the Mule applications and APIs being built to communicate with these stakeholders using Anypoint Platform and its supplied toolset?
A. Use Anypoint Design Center to implement the Mule applications and APIs and give the various stakeholders access to these Design Center projects, so they can collaborate and provide feedback
B. Create Anypoint Exchange entries with pages elaborating the integration design, including API notebooks (where applicable) to help the stakeholders understand and interact with the Mule applications and APIs at various levels of technical depth
C. Use Anypoint Exchange to register the various Mule applications and APIs and share the RAML definitions with the stakeholders, so they can be discovered
D. Capture documentation about the Mule applications and APIs inline within the Mule integration flows and use Anypoint Studio's Export Documentation feature to provide an HTML version of this documentation to the stakeholders
Explanation
As the stakeholders are semitechnical users , preferred option is Create Anypoint Exchange entries with pages elaborating the integration design, including API notebooks (where applicable) to help the stakeholders understand and interact with the Mule applications and APIs at various levels of technical depth
