B. Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:
%dw 2.0
Import.json-moduls

C. Add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema

問題6

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, 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

D. 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
