NEW QUESTION # 45
Which configurations are required for HTTP Listener to enable mTLS authentication?
Answer: A
Explanation:
To enable mTLS authentication for HTTP Listener, the developer needs to set an appropriate keystore and truststore configuration for the listener. The keystore contains the certificate and private key of the Mule application that are used to prove its identity to clients. The truststore contains the certificates of trusted clients that are allowed to access the Mule application. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#mutual-authentication
NEW QUESTION # 46
Refer to the exhibits.
A Mule application's pom.xml configures the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory.
Which configuration of this plugin achieves a successful build?
Exhibits - Options A and B:
Exhibits - Options C and D:
Answer: A
Explanation:
Resource filtering is designed primarily for textual resources in which Maven substitutes property expressions. Binary files such as PKCS#12 keystores and certificate files must not be passed through text filtering because filtering can corrupt their binary representation.
The Maven Resources Plugin provides the dedicated configuration element nonFilteredFileExtensions. Each additional extension is declared using a nested nonFilteredFileExtension. The plugin documentation specifically defines this parameter as the list of additional file extensions to which filtering must not be applied.
Option C correctly uses the documented structure:
< nonFilteredFileExtensions >
< nonFilteredFileExtension > p12 < /nonFilteredFileExtension >
< nonFilteredFileExtension > crt < /nonFilteredFileExtension >
< nonFilteredFileExtension > pem < /nonFilteredFileExtension >
< /nonFilteredFileExtensions >
This is important because the application's normal resource configuration can still use < filtering > true <
/filtering > for textual files while Maven leaves the listed certificate/keystore formats untouched.
The alternative constructs visible in the other exhibits, such as excludeFileExtensions or excludeBinaryFiles, are not the Maven Resources Plugin parameter used for this purpose.
Reference topics: Maven Resources Plugin; resource filtering; binary resources; nonFilteredFileExtensions; Mule Maven builds.

NEW QUESTION # 47
A developer is working on a project that requires encrypting all data before sending it to a backend application. To accomplish this, the developer will use PGP encryption in the Mule 4 Cryptography module.
What is required to encrypt the data before sending it to the backend application?
Answer: D
Explanation:
To encrypt the data before sending it to the backend application using PGP encryption, the application needs the public key from the backend service. PGP encryption uses a public-key cryptography system, which means that each party has a pair of keys: a public key and a private key. The public key is used to encrypt data, and the private key is used to decrypt data. Therefore, to encrypt data for a specific recipient (the backend service), the application needs to use the recipient's public key. The recipient can then use its own private key to decrypt the data.

NEW QUESTION # 48
A developer has created the first version of an API designed for business partners to work with commodity prices.
What should the developer do to allow more than one major version of the same API to be exposed by the implementation?
Answer: A
Explanation:
Major API versions should be distinguishable at the API's external URI rather than being encoded independently into every resource operation or into internal Mule flow names. MuleSoft recommends including the consumer-facing API version in the application URL, for example /v1/..., so clients can explicitly select the major API contract they intend to consume.
RAML supports this cleanly through the baseUri. A version variable can be included in the base URI, for example baseUri: https://api.example.com/v{version}, with the corresponding version or base URI parameter defined in the specification. This keeps the versioning concern at the API contract and endpoint-addressing level.
Changing every operation would unnecessarily duplicate version information. Modifying generated APIkit flow names affects Mule implementation internals but does not provide distinct public API addresses.
Similarly, manually changing generated HTTP listeners after scaffolding makes the implementation diverge from the API specification and weakens API-led lifecycle management.
MuleSoft's versioning guidance explicitly recommends exposing the major version in the API URL and using simple major identifiers such as v1, v2, and so forth.
Reference topics: API Versioning; RAML baseUri; Base URI Parameters; Major API Versions.

NEW QUESTION # 49
In a Mule project, Flow-1 contains a flow-ref to Flow-2. Flow-2 depends on data from Flow-1 to execute successfully.
Which action ensures the test suites and test cases written for Flow-1 and Flow-2 will execute successfully?
Answer: C
Explanation:
MUnit test cases should be independent and deterministic. A test for Flow-2 should not depend on another test case for Flow-1 executing first and leaving data behind. Such sequencing creates inter-test coupling, making test results dependent on execution order and complicating parallel execution, maintenance, and failure isolation.
The appropriate technique is to use Set Event in the Flow-2 test to construct the Mule Event that Flow-2 requires as input. MuleSoft documents Set Event as the processor normally placed at the start of an MUnit test to define the initial event sent to the flow being tested. It can independently define the payload, message attributes, and event variables.
Consequently, the Flow-2 tests can explicitly reproduce the payload or variables that Flow-1 would normally provide in production without requiring the Flow-1 test suite to execute first.
Before Test Case and After Test Case hooks are useful for setup and cleanup but should not be used to transfer output between otherwise separate unit tests. Chaining test suites similarly creates avoidable dependencies between tests.
Reference topics: MUnit; Set Event; independent unit tests; payload and variable initialization; deterministic testing.
