A Mule application includes a subflow containing a Scatter-Gather scope. Within each leg of the Scatter- Gather, an HTTP connector calls a PUT endpoint to modify records in different upstream systems. The subflow is called from inside an Until Successful scope to retry if a transient exception is raised.
A technical spike is being performed to increase reliability of the Mule application.
Which steps should be performed within the Mule flow above to ensure idempotent behavior?

• A. None; the flow already exhibits idempotent behavior
• B. Ensure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails
• C. Remove the PUT requests from the Scatter-Gather and perform them sequentially
• D. Change the PUT requests inside the Scatter-Gather to POST requests

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:

• A. Import RAML from local file
• B. Import a published API
• C. Download RAML from Design Center
• D. Generate a local RAML from Anypoint Studio

A developer deploys an API to CloudHub and applies an OAuth API policy in API Manager. During testing, the API response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policy is applied first, and the OAuth API policy is applied second.
What will happen when an HTTP request is received?

• A. In case of a cache miss, both the OAuth and HTTP Caching policies are evaluated; then the API retrieves the data from the API implementation, and the policy does not store the data in Object Store
• B. In case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data from the API implementation, and the policy stores the data to be cached in Object Store
• C. In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller
• D. In case of a cache hit, only the HTTP Caching policy is evaluated; then the cached response is returned to the caller

An organization uses CloudHub to deploy all of its applications.
How can a common-global-error-handler flow be configured so that it can be reused across all of the organization's deployed applications?

• A. Create a common-global-error-handler flow in all Mule applications. Refer to it via flow-ref wherever needed.
• B. Create a Mule domain project. Create a common-global-error-handler flow inside the domain project.
  Use this domain project as a dependency.
• C. Create a Mule plugin project. Create a common-global-error-handler flow inside the plugin project. Use this plugin as a dependency in all Mule applications. Import that configuration file in Mule applications.
• D. Create a Mule plugin project. Create a common-global-error-handler flow inside the plugin project. Use this plugin as a dependency in all Mule applications.

A Mule application defines an SSL/TLS keystore property "tls.keystore.keyPassword" as secure.
How can this property be referenced to access its value within the application?

• A. #[secure::tls.keystore.keyPassword]
• B. p(secure::tls.keystore.keyPassword)
• C. ${secure::tls.keystore.keyPassword}
• D. $(secure::tls.keystore.keyPassword)
