A developer has created the first version of an API designed for business partners to work commodity prices.
What should developer do to allow more than one major version of the same API to be exposed by the implementation?

• A.In Design Center, open the RAML and modify baseUn to include a variable that indicates the version number
• B.In Anypoint Studio, generate scaffolding from the RAML, and the modify the <http:listerner> in the generated flows to include a parameter to replace the version number
• C.In Design Center, open the RAML and modify each operation to include the major version number
• D.In Anypoint Studio, generate scaffolding from the RAML, and then modify the flow names generated by APIKit to include a variable with the major version number

Which statement is true when using XML SDK for creating custom message processors?

• A.Operations can be reused in recursive calls
• B.Properties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used
• C.An XML SDK provides both inbound and outbound operations
• D.All operations are public

A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production.
Which approach should be used to test that the payment API is working in production?

• A.Configure the application to send health data to an external system
• B.Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
• C.Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
• D.Monitor the Payment API directly sending real customer payment data

The Center for Enablement team published a common application as a reusable module to the central Nexus repository.
How can the common application be included in all API implementations?

• A.Download the common application from Naxus and copy it to the src/main/resources folder in the API
• B.Add a Maven dependency in the POM file with jar as <classifier>
• C.Add a Maven dependency in the PCM file with multiple-plugin as <classifier>
• D.Copy the common application's source XML file and out it in a new flow file in the src/main/mule folder

A developer deploys an API to CloudHub and applies an OAuth policy on 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 it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller
• B.In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller
• C.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
• D.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
