NEW QUESTION # 94
An organization is migrating all its Mule applications to Runtime Fabric (RTF). None of the Mule applications use Mule domain projects.
Currently, all the Mule applications have been manually deployed to a server group among several customer- hosted Mule runtimes. Port conflicts between these Mule application deployments are currently managed by the DevOps team who carefully manage Mule application properties files.
When the Mule applications are migrated from the current customer-hosted server group to Runtime Fabric (RTF), do the Mule applications need to be rewritten, and what DevOps port configuration responsibilities change or stay the same?
- A. YES, the Mule applications MUST be rewritten
DevOps NO LONGER needs to manage port conflicts between the Mule applications - B. NO, the Mule applications do NOT need to be rewritten
DevOps MUST STILL manage port conflicts - C. YES, the Mule applications MUST be rewritten
DevOps MUST STILL manage port conflicts - D. NO, the Mule applications do NOT need to be rewritten
DevOps NO LONGER needs to manage port conflicts between the Mule applications
Answer: A
NEW QUESTION # 95
An integration Mule application is being designed to process orders by submitting them to a backend system for offline processing. Each order will be received by the Mule application through an HTTPS POST and must be acknowledged immediately. Once acknowledged, the order will be submitted to a backend system. Orders that cannot be successfully submitted due to rejections from the backend system will need to be processed manually (outside the backend system).
The Mule application will be deployed to a customer-hosted runtime and is able to use an existing ActiveMQ broker if needed.
The backend system has a track record of unreliability both due to minor network connectivity issues and longer outages.
What idiomatic (used for their intended purposes) combination of Mule application components and ActiveMQ queues are required to ensure automatic submission of orders to the backend system, while minimizing manual order processing?
- A. Until Successful component
ActiveMQ long retry Queue
ActiveMQ Dead Letter Queue for manual processing - B. An On Error scope
Non-persistent VM
ActiveMQ Dead Letter Queue for manual processing - C. An On Error scope
MuleSoft Object Store
ActiveMQ Dead Letter Queue for manual processing - D. Until Successful component
MuleSoft Object Store
ActiveMQ is NOT needed or used
Answer: B
NEW QUESTION # 96
A rale limiting policy has been applied to a soap VI.2 API published in Clondhub. The API implementation catches errors in a global error handler on error propagate in the main flow for HTTP: RETRY_EXHAUSTED with HTTP status set to 429 and any with the HTTP status set to 500.
What is the expected H1TP status when the client exceeds the quota of the API calls?
- A. HTTP status 429 as defined in the HTTP:RETRY EXHAUSTED error handler in the API
- B. HTTP status 400 from the rate-limiting policy violation since the call does not reach the back-end
- C. HTTP status 401 unauthorized for policy violation
- D. HTTP status 500 as defined in the ANY error handler in the API since an API:RETRY_EXHAUSTED will be generated
Answer: A
Explanation:
In the given scenario, a rate limiting policy has been applied to the SOAP API and a global error handler is configured to handle HTTP:RETRY_EXHAUSTED errors with a 429 status code. The rate limiting policy will trigger when the client exceeds the allowed quota of API calls. Since the HTTP:RETRY_EXHAUSTED error specifically catches quota exhaustion errors and the error handler is configured to return a 429 status code, the expected HTTP status returned to the client when the quota is exceeded will be 429. This error code indicates that the user has sent too many requests in a given amount of time ("rate limiting").

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. A Mule application deployed to multiple nodes runs in an isolation from the other nodes in the cluster
- C. 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.
- D. An external load balancer is required to distribute incoming requests throughout the cluster nodes
Answer: D
NEW QUESTION # 98
An organization is not meeting its growth and innovation objectives because IT cannot deliver projects last enough to keep up with the pace of change required by the business.
According to MuleSoft's IT delivery and operating model, which step should the organization lake to solve this problem?
- A. Modify IT governance and security controls so that line of business developers can have direct access to the organization's systems of record
- B. Adopt a new approach that decouples core IT projects from the innovation that happens within each line of business
- C. Switch from a design-first to a code-first approach for IT development
- D. Hire more |T developers, architects, and project managers to increase IT delivery
Answer: B
Explanation:
MuleSoft's IT delivery and operating model suggests adopting an approach that decouples core IT projects from the innovation within each line of business. This approach, often referred to as API-led connectivity, allows different lines of business to innovate and deliver projects independently by using reusable APIs that provide access to core systems and data. This decoupling enhances agility, speeds up delivery, and ensures that core IT maintains control over critical systems and data while enabling rapid innovation.

NEW QUESTION # 99
An Order microservice and a Fulfillment microservice are being designed to communicate with their dients through message-based integration (and NOT through API invocations).
The Order microservice publishes an Order message (a kind of command message) containing the details of an order to be fulfilled. The intention is that Order messages are only consumed by one Mute application, the Fulfillment microservice.
The Fulfilment microservice consumes Order messages, fulfills the order described therein, and then publishes an OrderFulfilted message (a kind of event message). Each OrderFulfilted message can be consumed by any interested Mule application, and the Order microservice is one such Mute application.
What is the most appropriate choice of message broker(s) and message destination(s) in this scenario?
- A. Order messages are sent to a JMS queueOrderFulfilled messages are sent to a JMS topicBoth microservices Interact with the same JMS provider (message broker) Instance, which must therefore scale to support the load of both microservices
- B. Order messages are sent to a JMS queueOrderFulfilled messages are sent to a JMS topic The Order microservice Interacts with one JMS provider (message broker) and the Fulfillment microservice interacts with a different JMS provider, so that both message brokers can be chosen and scaled to best support the load of each microservice
- C. Older messages are sent directly to the Fulfillment microservices
OrderFulfilled messages are sent directly to the Order microservice
The Order microserviceInteracts with one AMQP-compatible message broker and the Fulfillment microservice Interactswith a different AMQP-compatible message broker, so that both message brokers can be chosen and scaled to best support the toad each microservice - D. O Order messages are sent to an Anypoint MQ exchange
OrderFulfilted messages are sent to an Anypoint MQ queue
Both microservices interact with Anypoint MQ as the message broker, which must therefore scale to support the toad of both microservices
Answer: A

NEW QUESTION # 104
Mule application A receives a request Anypoint MQ message REQU with a payload containing a variable-length list of request objects. Application A uses the For Each scope to split the list into individual objects and sends each object as a message to an Anypoint MQ queue.
Service S listens on that queue, processes each message independently of all other messages, and sends a response message to a response queue.
Application A listens on that response queue and must in turn create and publish a response Anypoint MQ message RESP with a payload containing the list of responses sent by service S in the same order as the request objects originally sent in REQU.
Assume successful response messages are returned by service S for all request messages.
What is required so that application A can ensure that the length and order of the list of objects in RESP and REQU match, while at the same time maximizing message throughput?
- A. Keep track of the list length and all object indices in REQU, both in the For Each scope and in all communication involving service Use persistent storage when creating RESP
- B. Use an Async scope within the For Each scope and collect response messages in a second For Each scope in the order In which they arrive, then send RESP using this list of responses
- C. Use a Scatter-Gather within the For Each scope to ensure response message order Configure the Scatter-Gather with a persistent object store
- D. Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU
Answer: A
Explanation:
Correct answer is Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU Explanation : Using Anypoint MQ, you can create two types of queues: Standard queue These queues don't guarantee a specific message order. Standard queues are the best fit for applications in which messages must be delivered quickly.
FIFO (first in, first out) queue These queues ensure that your messages arrive in order. FIFO queues are the best fit for applications requiring strict message ordering and exactly-once delivery, but in which message delivery speed is of less importance Use of FIFO queue is no where in the option and also it decreased throughput. Similarly persistent object store is not the preferred solution approach when you maximizing message throughput. This rules out one of the options. Scatter Gather does not support ObjectStore. This rules out one of the options. Standard Anypoint MQ queues don't guarantee a specific message order hence using another for each block to collect response wont work as requirement here is to ensure the order. Hence considering all the above factors the feasible approach is Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU
NEW QUESTION # 105
A high-volume eCommerce retailer receives thousands of orders per hour and requires notification of its order management, warehouse, and billing system for subsequent processing within 15 minutes of order submission through its website.
Which integration technology, when used for its typical and intended purpose, meets the retailer's requirements for this use case?
- A. Managed File Transfer (MFT)
- B. Publish/Subscriber Messaging Bus (Pub/Sub)
- C. Enterprise Data Warehouse (EDW)
- D. Extract Transform Load (ETL)
Answer: B
Explanation:
The Publish/Subscriber Messaging Bus (Pub/Sub) model is well-suited for high-volume, real-time communication and notification requirements. In this scenario, the retailer needs to notify its order management, warehouse, and billing systems within 15 minutes of order submission. Pub/Sub messaging systems enable asynchronous communication where messages (orders) are published to a topic and multiple subscribers (order management, warehouse, billing systems) receive notifications simultaneously. This decouples the systems and ensures that each subscriber receives the message promptly for subsequent processing.
