질문 # 16
Mule application A is deployed to CloudHub and is using Object Store v2. Mule application B is also deployed to CloudHub.
Which approach can Mule application B use to remove values from Mule application A's Object Store?
정답：A
설명：
Object Store Connector provides Mule operations for interacting with object stores associated with the application in which the connector executes. It is not the mechanism for one independently deployed CloudHub application to directly operate on another application's Object Store v2 data.
For cross-application administration and access, MuleSoft provides the Object Store v2 REST APIs. These APIs support listing object stores and keys, storing and retrieving key-value pairs, and explicitly deleting keys and their values. Calls are authenticated with an Anypoint Platform bearer token and address the required organization, environment, store, partition, and key. MuleSoft's documented DELETE operation removes a specified key-value pair from the targeted Object Store v2 partition.
The CloudHub REST API manages CloudHub resources and deployments rather than application Object Store entries. The CloudHub Connector likewise does not provide the direct cross-application Object Store v2 deletion capability described here.
Therefore, application B can invoke the Object Store v2 REST API, subject to appropriate authorization and identification of application A's relevant Object Store resources, to remove values from that store.
Reference topics: Object Store v2; Object Store v2 REST APIs; partitions and keys; DELETE operations; CloudHub persistence.

Refer to the exhibit.
What required changes can be made to give a partial successful response in case the United Airlines API returns with a timeout?
Exhibit:
정답：C
설명：
Scatter-Gather normally expects all routes to complete successfully before combining their results. If the United Airlines route times out and that error escapes the route, Scatter-Gather raises a MULE:
COMPOSITE_ROUTING error instead of continuing normally to the downstream Transform Message. That behavior prevents the required partial-success response.
The correct design is to handle failure inside the affected Scatter-Gather route. Each Flow Reference can be wrapped in a Try scope, with the timeout or relevant connector error handled using On Error Continue. The handler can replace the failed route's payload with a neutral/default value such as an empty string. The route is then considered successfully handled, allowing Scatter-Gather to consolidate the successful Delta response and the default United value and proceed to the concatenation step.
MuleSoft documents this exact Scatter-Gather behavior: when a route's Try scope successfully handles an error with on-error-continue, Scatter-Gather completes and passes the combined events onward. If on-error- propagate is used, the route remains failed and Scatter-Gather produces a composite-routing error.
Reference topics: Scatter-Gather Router; Try Scope; On Error Continue; partial results; MULE:
COMPOSITE_ROUTING.

질문 # 18
An order processing system is composed of multiple Mule applications responsible for warehouse, sales, and shipping. Each application communicates using Anypoint MQ. Each message must be correlated against the original order ID for observability and tracing.
How should a developer propagate the order ID as the correlation ID across each message?
정답：D
설명：
This answer requires an important correction to the selection shown in the supplied material. MuleSoft's current Anypoint MQ documentation explicitly states that Anypoint MQ does not propagate Mule correlationId from publisher to subscriber in the same way that APIs propagate correlation IDs between layers. MuleSoft instructs developers to place the required identifier in an Anypoint MQ user property and consume that value in the receiving application.
Therefore, the publishing application should include the original orderId as a custom message property. When another Mule application consumes the MQ message, it extracts that property and establishes the appropriate correlation context for its processing. The Tracing Module's With CorrelationID scope can then be used within that receiving application if the event correlation ID needs to be changed to the supplied order ID.
MuleSoft confirms that With CorrelationID temporarily modifies the Mule event's correlation ID for processors inside the scope.
Wrapping only the publisher in With CorrelationID does not make Anypoint MQ transport that Mule event correlation ID automatically. Option D is explicitly contradicted by MuleSoft's MQ documentation.
Reference topics: Anypoint MQ user properties; correlation propagation; Tracing Module; With CorrelationID; distributed observability.

질문 # 19
Two APIs are deployed to a two-node on-prem cluster. Due to a requirements change, the two APIs must communicate to exchange data asynchronously.
How can this be solved?
정답：B
설명：
VM Connector supports both intra-application and inter-application asynchronous communication. MuleSoft specifically documents that two different Mule applications can publish to and consume from the same VM queue when both applications are part of the same Mule domain and reference the shared VM configuration.
The fact that the applications are deployed to a two-node Mule cluster does not prevent use of VM Connector.
In cluster mode, VM queues are cluster-wide resources. Mule's cluster synchronizes access, and messages placed on a VM queue can be processed by another node in the cluster. MuleSoft identifies this as a supported mechanism for distributing asynchronous work across clustered runtime instances.
Therefore, option B is incorrect: each node does not operate an entirely isolated VM queue namespace for a shared clustered configuration. Option D also contradicts VM Connector's documented inter-application use case.
The required architectural condition is that both applications use the same domain/shared VM configuration so they can reference the same queue. The publisher can then send asynchronously while the second API consumes from the shared VM queue.
Reference topics: VM Connector; Mule domains; inter-application communication; persistent/transient queues; Mule HA clustering.

질문 # 20
Refer to the exhibit.
A Mute Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.
What is the result of the flow if processing between os'store and os:retrieve takes 10 seconds?
정답：C
설명：
The result of the flow is nullPayload if processing between os:store and os:retrieve takes 10 seconds. This is because the entry TTL of the object store is one second, which means that any stored value expires after one second and is removed from the object store. The expiration interval of 30 seconds only determines how often the object store checks for expired values, but it does not affect the TTL. Therefore, when os:retrieve tries to get the value after 10 seconds, it returns nullPayload because the value has already expired and been removed.
