http:localhost:8081/vehicles.

If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP

Request operation when the flow executes?

A : The HTTP Request operation will succeed if the CA’S certificate is present in the JRE’s default keystore

B : The HTTP Request operation will succeed if the CA’s certificate is present in the JRE’s default truststore.

C : The HTTP Request operation will always succeed regardless of the CA

D : The HTTP Request operation will always fail regardless of the CA

Answer: B

Question 2

A Mule application need to invoice an API hosted by an external system to initiate a process. The external API

takes anywhere between one minute and 24 hours to compute its process.

Which implementation should be used to get response data from the external API after it completes

B : In case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returnedto the caller

C : In case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data fromthe 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 APIretrieves the data from the API implementation, and the policy does not store the data in Object Store

Answer: B
