storeld and department name?
A)

B)

C)

D)

• A. Option A
• B. Option B
• C. Option C
• D. Option D

Question 9

An API instance of type API endpoint with API proxy is created in API manager using an API
specification from Anypoint Exchange. The API instance is also configured with an API proxy that is
deployed and running in CloudHub.
