NEW QUESTION # 21
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: B
NEW QUESTION # 22
Refer to the exhibit.
When creating a new project, which API implementation allows for selecting the correct API version and scaffolding the flows from the API specification?
Answer: D
Explanation:
To create a new project that selects the correct API version and scaffolds the flows from the API specification, the developer should import a published API. This option allows importing an API specification that has been published to Anypoint Exchange or Design Center, and selecting a specific version of that API specification. The developer can also choose to scaffold flows based on that API specification. Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-new-project-task
NEW QUESTION # 23
A Mule application needs to invoke an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to complete its process.
Which implementation should be used to get response data from the external API after it completes processing?
Answer: D
Explanation:
A process that can require up to 24 hours is inherently asynchronous. The initiating Mule application should not keep an HTTP connection open until the remote system completes. Instead, Mule should initiate the process, return or continue independently, and expose an HTTP callback endpoint that the external system invokes when processing finishes.
The callback URL is registered with the external system so that completion data can be pushed back to Mule.
This separates request initiation from completion notification and avoids tying up network connections or execution resources for an unpredictable duration. Callback-based processing is a standard asynchronous integration mechanism; MuleSoft documentation uses callback endpoints extensively where a remote system must later contact a Mule application.
Polling every minute is inefficient over a possible 24-hour interval and can generate large volumes of unnecessary requests. An Async scope does not transform a fundamentally synchronous HTTP request into a
24-hour callback model; the downstream HTTP connection would still be governed by response and connection timeout behavior. Waiting synchronously is even less appropriate.
Therefore, exposing a Mule HTTP callback API and registering it with the external system provides the most scalable and reliable architecture.
Reference topics: asynchronous integration; callback APIs; HTTP Listener; long-running processes; event- driven completion notification.

NEW QUESTION # 24
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:
API Autodiscovery is what pairs a Mule application with a particular API Manager instance. The apiId in the Autodiscovery configuration identifies the managed API from which the runtime obtains API configuration and policies. Therefore, using an environment-specific configuration for local development prevents the locally running application from binding to the production API instance and consequently prevents those production policies from governing local test traffic.
This is different from setting anypoint.platform.gatekeeper=disabled. Gatekeeper controls whether a managed API is blocked while policy information is unavailable or being synchronized; disabling Gatekeeper is not equivalent to disabling API Manager policies. Policies can still be downloaded and applied when the application remains paired through Autodiscovery.
Running the application unchanged is also incorrect because a locally executed Mule runtime can connect to API Manager when Autodiscovery and platform credentials are configured. MuleSoft explicitly documents local Autodiscovery for policy testing. Deactivating the shared API is likewise inappropriate because it modifies centrally managed configuration rather than isolating the developer's local environment.
Reference topics: API Autodiscovery; API Instance ID; Environment-specific Configuration; Mule Gateway Gatekeeper.

NEW QUESTION # 25
A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?
Answer: A
Explanation:
To handle a permanent error response like HTTP:UNAUTHORIZED inside Until Successful, the developer should put the HTTP Request inside a try scope in Unit Successful, and use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED in the error handler. This way, the developer can avoid retrying requests that will always fail due to a permanent error, and reduce latency. On Error Continue allows the flow to continue processing after handling the error.
