We have three versions of our Mule-Dev-301 exam questions: the PDF, Software and APP online. Because our PDF version of the learning material is available for customers to print, so that your free time is fully utilized. Everything you do will help you pass the Mule-Dev-301 Exam and get your Mule-Dev-301 certificate. Of course, the APP and PC versions are also very popular. They can simulate the actual operation of the test environment, and users can perform mock tests for a limited time.
NEW QUESTION # 54
A custom policy needs to be developed to intercept all outbound HTTP requests made by Mule applications.
Which XML element must be used to intercept outbound HTTP requests?
Answer: C
NEW QUESTION # 55
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?
Answer: C
Explanation:
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.

NEW QUESTION # 56
Refer to the exhibit.
When creating a new project, which API implementation allows for selecting the correct API version and scaffolding flows from the API specification?
Exhibit:
Answer: A
Explanation:
When an API specification has already been published as an asset, Import a published API is the appropriate project-creation path because Anypoint Studio can resolve the published asset and its version and then use that specification to generate the Mule implementation skeleton.
APIkit scaffolding creates the implementation backbone from the selected specification, including the HTTP Listener entry flow, APIkit Router, console-related configuration, and operation-specific implementation flows. MuleSoft currently documents that Studio can scaffold APIs by importing a published API from Exchange/Maven, importing a local specification, or obtaining one from Design Center. However, the distinguishing requirement in this question is selecting the correct published API version. A published Exchange asset has explicit artifact/version coordinates, allowing the intended version to be selected rather than merely working from an unmanaged local RAML file.
Importing a local RAML can generate flows, but it does not inherently provide Exchange-based artifact
/version selection. Likewise, "Generate a local RAML" is not the mechanism shown in the new-project API implementation interface.
Reference topics: APIkit for REST; API Scaffolding; Anypoint Exchange API assets; API version selection; Studio project creation.

NEW QUESTION # 57
When a client and server are exchanging messages during the mTLS handshake, what is being agreed on during the cipher suite exchange?
Answer: C
Explanation:
A cipher suite is a set of cryptographic algorithms that are used to secure the communication between a client and a server. A cipher suite consists of four components: a key exchange algorithm, an authentication algorithm, an encryption algorithm, and a message authentication code (MAC) algorithm. During the cipher suite exchange, the client and the server agree on which encryption algorithm to use for encrypting and decrypting the data.

NEW QUESTION # 58
A scatter-gather router is configured with four routes: Route A, B, C and D.
Route C fails.
Which expression allows access to the failing route so that it can be compensated?
Answer: B
Explanation:
When any route within Scatter-Gather fails, Mule raises a MULE:COMPOSITE_ROUTING error after the routes complete. The information associated with each route is retained in the error message payload. This payload contains separate collections for failures and results, indexed according to the route positions.
Routes are zero-indexed for this structure: Route A corresponds to index 0, Route B to index 1, Route C to index 2, and Route D to index 3. Because Route C failed, its failure information is therefore available from the failures structure at index 2.
Critically, this data belongs to the Mule error's errorMessage.payload; it is not simply the current event payload. Consequently, payload.failures[2] and payload[2] address the wrong structure. Likewise, error.
errorMessage.payload.results[2] refers to the successful-results collection; for a failed route, the relevant object is stored under failures.
MuleSoft's Scatter-Gather documentation demonstrates the same mechanism, accessing failed route information through expressions such as error.errorMessage.payload.failures['0'] and successful route output through the corresponding results collection.
Reference topics: Scatter-Gather Error Handling; MULE:COMPOSITE_ROUTING; Route Results and Failures; Compensation Logic.
