An automation engineer needs to write scripts to automate the steps of the API lifecycle, including steps to create, publish, deploy and manage APIs and their implementations in Anypoint Platform. What Anypoint Platform feature can be used to automate the execution of all these actions in scripts in the easiest way without needing to directly invoke the Anypoint Platform REST APIs?
A. Automated Policies in API Manager
B. Runtime Manager agent
C. The Mule Maven Plugin
D. Anypoint CLI
Explanation
Anypoint Platform provides a scripting and command-line tool for both Anypoint Platform and Anypoint Platform Private Cloud Edition (Anypoint Platform PCE). The command-line interface (CLI) supports both the interactive shell and standard CLI modes and works with: Anypoint Exchange Access management Anypoint Runtime Manager
In a Mule Application, a flow contains two (2) JMS consume operations that are used to connect to a JMS broker and consume messages from two(2) JMS destination. The Mule application then joins the two JMS messages together. The JMS broker does not implement high availability (HA) and periodically experiences scheduled outages of upto 10 mins for routine maintenance. What is the most idiomatic (used for its intented purpose) way to build the mule flow so it can best recover from the expected outages?
A. Configure a reconnection strategy for the JMS connector
B. Enclose the two(2) JMS operation in an Until Successful scope
C. Consider a transaction for the JMS connector
D. Enclose the two(2) JMS operations in a Try scope with an Error Continue error handler
Explanation
When an operation in a Mule application fails to connect to an external server, the default behavior is for the operation to fail immediately and return a connectivity error. You can modify this default behavior by configuring a reconnection strategy for the operation. You can configure a reconnection strategy for an operation either by modifying the operation properties or by modifying the configuration of the global element for the operation. The following are the available reconnection strategies and their behaviors: None Is the default behavior, which immediately returns a connectivity error if the attempt to connect is unsuccessful Standard (reconnect) Sets the number of reconnection attempts and the interval at which to execute them before returning a connectivity error Forever (reconnect-forever) Attempts to reconnect continually at a given interval
According to MuleSoft, which major benefit does a Center for Enablement (C4E) provide for an enterprise and its lines of business?
A. Enabling Edge security between the lines of business and public devices
B. Centralizing project management across the lines of business
C. Centrally managing return on investment (ROI) reporting from lines of business to leadership
D. Accelerating self-service by the lines of business
Explanation:
A Center for Enablement (C4E) provides significant benefits to an enterprise and its lines of business by accelerating self-service capabilities. A C4E is a cross-functional team that promotes the use of best practices, reusable assets, and consistent methodologies across the organization. By enabling lines of business to access and use shared resources, tools, and knowledge independently, a C4E empowers these units to deliver projects faster and more efficiently. This self-service model reduces reliance on central IT for every initiative, fosters innovation, and enhances the overall agility of the organization.

Best Practices for Implementing a C4E on Anypoint Platform
A Center for Enablement (C4E) provides significant benefits by accelerating self-service
capabilities for lines of business. Here’s how:
Self-Service Enablement: C4E empowers lines of business to access, use, and create integrations and APIs independently, without relying heavily on central IT teams.
Guidelines and Standards: The C4E establishes best practices, standards, and reusable frameworks, ensuring that lines of business can develop solutions efficiently and consistently.
Faster Time-to-Market: By enabling self-service, lines of business can rapidly develop and deploy solutions to meet their specific needs, resulting in faster time-to-market for new initiatives.
Reduced Bottlenecks: Self-service reduces dependency on central IT, alleviating potential bottlenecks and allowing IT to focus on governance, security, and strategic projects.
The C4E model thus accelerates innovation and responsiveness within the enterprise.

When using Anypoint Platform across various lines of business with their own Anypoint Platform business groups, what configuration of Anypoint Platform is always performed at the organization level as opposed to at the business group level?
A. Environment setup
B. Identity management setup
C. Role and permission setup
D. Dedicated Load Balancer setup
Explanation
* Roles are business group specific. Configure identity management in the Anypoint Platform master organization. As the Anypoint Platform organization administrator, you can configure identity management in Anypoint Platform to set up users for single sign-on (SSO). * Roles and permissions can be set up at business group and organization level also. But Identity Management setup is only done at Organization level * Business groups are self-contained resource groups that contain Anypoint Platform resources such as applications and APIs. Business groups provide a way to separate and control access to Anypoint Platform resources because users have access only to the busine
A Mule application is built to support a local transaction for a series of operations on a single database. The mule application has a Scatter-Gather scope that participates in the local transaction. What is the behavior of the Scatter-Gather when running within this local transaction?
A. Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations
B. Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back
C. Execution of all routes within Scatter-Gather occurs sequentially Any error that occurs inside Scatter-Gather will result in a roll back of all the database operations
D. Execution of all routes within Scatter-Gather occurs in parallel Any error that occurs inside Scatter-Gather will be handled by error handler and will not result in roll back

As a part of project requirement, client will send a stream of data to mule application. Payload size can vary between 10mb to 5GB. Mule application is required to transform the data and send across multiple sftp servers. Due to the cost cuttings in the organization, mule application can only be allocated one worker with size of 0.2 vCore. As an integration architect , which streaming strategy you would suggest to handle this scenario?
A. In-memory non repeatable stream
B. File based non-repeatable stream
C. In-memory repeatable stream
D. File based repeatable storage
Explanation
As the question says that data needs to be sent across multiple sftp serves , we cannot use non-repeatable streams. The non-repeatable strategy disables repeatable streams, which enables you to read an input stream only once.
You cant use in memory storage because with 0.2 vcore you will get only 1 GB of heap memory. Hence application will error out for file more than 1 GB.
Hence the correct option is file base repeatable stream
An organization is successfully using API led connectivity, however, as the application network grows, all the manually performed tasks to publish share and discover, register, apply policies to, and deploy an API are becoming repetitive pictures driving the organization to automate this process using efficient CI/'CD pipeline. Considering Anypoint platforms capabilities how should the organization approach automating is API lifecycle?
A. Use runtime manager rest apis for API management and mavenforAPI deployment
B. Use Maven with a custom configuration required for the API lifecycle
C. Use Anypoint CLI or Anypoint Platform REST apis with scripting language such as groovy
D. Use Exchange rest api's for API management and MavenforAPI deployment
Explanation:
To automate the API lifecycle in a CI/CD pipeline efficiently, leveraging Anypoint Platform's capabilities is crucial. Anypoint CLI (Command Line Interface) and Anypoint Platform REST APIs provide robust tools for managing various aspects of the API lifecycle, such as publishing, sharing, discovering, registering, applying policies, and deploying APIs. By using these tools with a scripting language like Groovy, you can script and automate these tasks to reduce manual intervention, ensuring consistency and efficiency.
Anypoint CLI allows you to interact with the Anypoint Platform from the command line, enabling automated deployments, management of APIs, and configuration of policies. The Anypoint Platform REST APIs provide comprehensive programmatic access to the platform’s functionalities, allowing for seamless integration into CI/CD pipelines. By combining these with a scripting language, you can create scripts that automate repetitive tasks, streamline processes, and ensure that your API lifecycle management is both efficient and reliable.

In which order are the API Client, API Implementation, and API interface components called in a typical REST request?
A. API Client > API implementation > API Interface
B. API interface > API Client > API Implementation
C. API Client > API Interface > API implementation
D. API Implementation > API Interface > API Client
Explanation:
In a typical REST request, the order of interaction is:
API Client: The client initiates the request to access data or functionality exposed by the API.
API Interface: This represents the contract or the definition of the API, often specified in OpenAPI or RAML. It defines the endpoints, request/response formats, and other API details.
API Implementation: This is the actual backend logic that processes the request and returns the response. It interacts with databases, other services, or performs business logic to fulfill the request.

Insurance organization is planning to deploy Mule application in MuleSoft Hosted runtime plane. As a part of requirement , application should be scalable . highly available. It also has regulatory requirement which demands logs to be retained for at least 2 years. As an Integration Architect what step you will recommend in order to achieve this?
A. It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required.
B. When deploying an application to CloudHub , logs retention period should be selected as 2 years
C. When deploying an application to CloudHub, worker size should be sufficient to store 2 years data
D. Logging strategy should be configured accordingly in log4j file deployed with the application.
Explanation
Correct answer is It is not possible to store logs for 2 years in CloudHub deployment. External log management system is required. CloudHub has a specific log retention policy, as described in the documentation: the platform stores logs of up to 100 MB per app & per worker or for up to 30 days, whichever limit is hit first. Once this limit has been reached, the oldest log information is deleted in chunks and is irretrievably lost. The recommended approach is to persist your logs to a external logging system of your choice (such as Splunk, for instance) using a log appender. Please note that this solution results in the logs no longer being stored on our platform, so any support cases you lodge will require for you to provide the appropriate logs for review and case resolution
A Mule application name Pub uses a persistence object store. The Pub Mule application is deployed to Cloudhub and it configured to use Object Store v2. Another Mule application name sub is being developed to retrieve values from the Pub Mule application persistence object Store and will also be deployed to cloudhub. What is the most direct way for the Sub Mule application to retrieve values from the Pub Mule application persistence object store with the least latency?
A. Use an object store connector configured to access the Pub Mule application persistence object store
B. Use a VM connector configured to directly access the persistence queue of the Pub Mule application persistence object store.
C. Use an Anypoint MQ connector configured to directly access the Pub Mule application persistence object store
D. Use the Object store v2 REST API configured to access the Pub Mule application persistence object store.
Explanation
* The Object Store V2 API enables API access to Anypoint Platform Object Store v2.
* You can configure a Mule app to use the Object Store REST API to store and retrieve values from an object store in another Mule app. However, Object Store v2 is not designed for app-to-app communication. To share data between two Mule4 apps, use a queue in Anypoint MQ.
* The Object Store v2 APIs enable you to use REST to perform the following:
- Retrieve a list of object stores and keys associated with an application.
- Store and retrieve key-value pairs in an object store.
- Delete key-value pairs from an object store.
- Retrieve Object Store usage statistics for your organization.
- Object Store provides these APIs:
Object Store API
Object Store Stats API
