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 contacted to understand the change to existing functionality.
• C.The API producer should be requested to run the old version in parallel with the new one.
• D.The API client code ONLY needs to be changed if it needs to take advantage of new features.

Correct Answer: D

* Semantic Versioning is a 3-component number in the format of X.Y.Z, where :
X stands for a major version.
Y stands for a minor version:
Z stands for a patch.
So, SemVer is of the form Major.Minor.Patch Coming to our question , minor version of the API has been changed which is backward compatible. Hence there is no change required on API client end. If they want to make use of new featured that have been added as a part of minor version change they may need to change code at their end. Hence correct answer is The API client code ONLY needs to be changed if it needs to take advantage of new features.

An external REST client periodically sends an array of records in a single POST request to a Mule application API endpoint.
The Mule application must validate each record of the request against a JSON schema before sending it to a downstream system in the same order that it was received in the array Record processing will take place inside a router or scope that calls a child flow. The child flow has its own error handling defined. Any validation or communication failures should not prevent further processing of the remaining records.
To best address these requirements what is the most idiomatic(used for it intended purpose) router or scope to used in the parent flow, and what type of error handler should be used in the child flow?

• A.Until Successful router in the parent flow
  On Error Propagate error handler in the child flow
• B.First Successful router in the parent flow
  On Error Continue error handler in the child flow
• C.Parallel For Each scope in the parent flow
  On Error Propagate error handler in the child flow
• D.For Each scope in the parent flow
  On Error Continue error handler in the child flow

An Organization has previously provisioned its own AWS VPC hosting various servers. The organization now needs to use Cloudhub to host a Mule application that will implement a REST API once deployed to Cloudhub, this Mule application must be able to communicate securely with the customer-provisioned AWS VPC resources within the same region, without being interceptable on the public internet.
What Anypoint Platform features should be used to meet these network communication requirements between Cloudhub and the existing customer-provisioned AWS VPC?

• A.Add a Mulesoft hosted Anypoint VPC configured and with VPC Peering to the AWS VPC
• B.Configure an external identity provider (IDP) in Anypoint Platform with certificates from the customer provisioned AWS VPC
• C.Add a default API Whitelisting policy to API Manager to automatically whitelist the customer provisioned AWS VPC IP ranges needed by the Mule applicaton
• D.Use VM queues in the Mule application to allow any non-mule assets within the customer provisioned AWS VPC to subscribed to and receive messages
