What correctly characterizes unit tests of Mule applications?

• A.They test the validity of input and output of source and target systems
• B.They must be run in a unit testing environment with dedicated Mule runtimes for the environment
• C.They must be triggered by an external client tool or event source
• D.They are typically written using MUnit to run in an embedded Mule runtime that does not require external connectivity

An API implementation is deployed on a single worker on CloudHub and invoked by external API clients (outside of CloudHub). How can an alert be set up that is guaranteed to trigger AS SOON AS that API implementation stops responding to API invocations?

• A.Create an alert for when the API receives no requests within a specified time period
• B.Handle API invocation exceptions within the calling API client and raise an alert from that API client when the API Is unavailable
• C.Implement a heartbeat/health check within the API and invoke it from outside the Anypoint Platform and alert when the heartbeat does not respond
• D.Configure a "worker not responding" alert in Anypoint Runtime Manager

How can the application of a rate limiting API policy be accurately reflected in the RAML definition of an API?

• A.By refining the request definitions by adding a remaining Requests query parameter with description, type, and example
• B.By refining the resource definitions by adding a description of the rate limiting policy behavior
• C.By refining the response definitions by adding the out-of-the-box Anypoint Platform rate-limit-enforcement securityScheme with description, type, and example
• D.By refining the response definitions by adding the x-ratelimit-* response headers with description, type, and example

An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to 3.2.0 following accepted semantic versioning practices and the changes have been communicated via the API's public portal.
The API endpoint does NOT change in the new version.
How should the developer of an API client respond to this change?

• A.The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run
• B.The API producer should be requested to run the old version in parallel with the new one
• C.The API client code ONLY needs to be changed if it needs to take advantage of new features
• D.The API producer should be contacted to understand the change to existing functionality

Refer to the exhibit.

what is true when using customer-hosted Mule runtimes with the MuleSoft-hosted Anypoint Platform control plane (hybrid deployment)?

• A.API implementations can run successfully in customer-hosted Mule runtimes, even when they are unable to communicate with the control plane
• B.Anypoint Runtime Manager automatically ensures HA in the control plane by creating a new Mule runtime instance in case of a node failure
• C.The MuleSoft-hosted Shared Load Balancer can be used to load balance API invocations to the Mule runtimes
• D.Anypoint Runtime Manager initiates a network connection to a Mule runtime in order to deploy Mule applications
