NEW QUESTION # 38
Which configurations are required for HTTP Listener to enable mTLS authentication?
Answer: B
Explanation:
Mutual TLS requires authentication in both directions. The Mule HTTP Listener acts as the TLS server, so it needs a keystore containing its private key and associated server certificate. This allows the listener to prove its identity to the connecting client.
For mTLS, the server must additionally authenticate the client certificate. Therefore, the TLS context also requires an appropriate truststore containing the certificate authorities or certificates that the application trusts when validating client certificates.
MuleSoft's TLS documentation provides a two-way authentication example for an HTTP Listener containing both < tls:trust-store > and < tls:key-store > inside the TLS context. MuleSoft's HTTP Listener documentation likewise states that HTTPS requires a keystore for the server and a truststore when two-way authentication is required.
Persistent connections affect HTTP connection reuse and performance, not certificate authentication. A reconnection strategy likewise does not provide the cryptographic identity material required for mTLS.
Therefore, an HTTP Listener configured for mutual TLS requires the correct keystore and truststore configuration.
Reference topics: Mule TLS Context; HTTP Listener HTTPS; keystores; truststores; mutual TLS/two-way authentication.

NEW QUESTION # 39
A Mule application deployed to multiple CloudHub 2.0 replicas needs to temporarily persist large files over
10MB between flow executions, and routinely needs to query whether the file data exists on separate executions.
How can this be achieved?
Answer: B
Explanation:
Object Store v2 is suitable for distributed key/value state that must be available across CloudHub executions and replicas, but it should not be used to hold the complete contents of files larger than its per-value limit.
MuleSoft documents that an Object Store v2 value is limited to 10 MB, while the overall store does not have a fixed aggregate size limit.
The appropriate architecture is therefore to persist the binary file itself in storage designed for large objects- for example, a durable external object/blob storage service-and store only lightweight metadata in Object Store v2. That metadata can include the object's storage key, URI/location, status, or other lookup information. Subsequent flow executions can query Object Store v2 to determine whether the object exists and then retrieve the actual file from the external storage system.
An in-memory Object Store is inappropriate because application replicas do not provide a durable shared in- memory persistence model for this requirement. Storing the entire file directly in Object Store violates the 10 MB value constraint. Local file-based storage is also unsuitable as a cross-replica CloudHub persistence mechanism.
Reference topics: Object Store v2 limits; CloudHub replicas; distributed persistence; external object storage; key/location metadata.

NEW QUESTION # 40
An API has been developed and deployed to CloudHub Among the policies applied to this API is an allowlist of IP addresses. A developer wants to run a test in Anypoint Studio and does not want any policies applied because their workstation is not included in the allowlist.
What must the developer do in order to run this test locally without the policies applied?
Answer: D
Explanation:
To run a test locally without the policies applied, the developer should create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager. This way, the developer can use different configuration properties for different environments and avoid triggering API autodiscovery when running tests locally. API autodiscovery is a mechanism that associates an API implementation with its corresponding API specification and policies in API Manager based on its API instance ID. By setting this ID to a value that does not exist in API Manager, the developer can prevent API autodiscovery from finding and applying any policies to the local test.

NEW QUESTION # 41
A Mule application deployed to a standalone Mule runtime uses VM queues to publish messages to be consumed asynchronously by another flow.
In the case of a system failure, what will happen to in-flight messages in the VM queues that have not been consumed?
Answer: D
Explanation:
VM Connector supports both transient and persistent asynchronous queues, and their recovery behavior differs fundamentally. MuleSoft specifies that transient queues provide better performance but are not reliable when the runtime or host fails. Persistent queues are slower because their content must be persisted, but they provide recovery across failures.
For a standalone Mule runtime, persistent VM queues serialize and store queued message data on disk.
Consequently, if the Mule runtime or underlying system stops before an in-flight queued message is consumed, the message can remain available and processing can resume after the runtime becomes operational again.
A transient queue stores its queued state in volatile runtime memory. A system failure destroys that state, so an unconsumed transient message cannot be assumed to survive restart.
Therefore, neither "all messages are lost" nor "all messages are recovered" accurately describes VM behavior; durability depends specifically on the queue type.
For workloads where asynchronous events must survive process or host failure in a supported standalone runtime architecture, a persistent VM queue is therefore the appropriate choice.
Reference topics: VM Connector; persistent queues; transient queues; asynchronous messaging; durability and recovery.

NEW QUESTION # 42
Refer to the exhibits.
The flow name is "implementation" with code for the MUnit test case.
When the MUnit test case is executed, what is the expected result?
Exhibit:
Answer: A
Explanation:
The significant attribute in the MUnit definition is expectedErrorType="APP:CUSTOM_ERROR". The referenced implementation flow deliberately invokes raise-error with exactly the same error type: APP:
CUSTOM_ERROR.
MUnit supports expected-error testing specifically for negative scenarios. When expectedErrorType is configured, the test is considered successful when execution produces that expected Mule error. The raised error is therefore not treated as an unexpected test failure; it satisfies the test's declared expectation.
The apparently failing assertion-testing true against equalTo(false)-does not change the result in this scenario because normal execution does not reach the validation chain after the referenced flow raises the expected error. The expected error terminates the execution path being tested and satisfies the MUnit expectation.
If the implementation generated a different error type, option B would apply. If it generated no error when an error was expected, the test would also fail. Here, however, the flow explicitly raises the exact application- defined error specified by the test.
Reference topics: MUnit Test Structure; expectedErrorType; Error Testing; Raise Error Component.
