Refer to the exhibit.
A business process involves two APIs that interact with each other asynchronously over HTTP. Each API is implemented as a Mule application. API 1 receives the initial HTTP request and invokes API 2 (in a fire and forget fashion) while API 2, upon completion of the processing, calls back into API l to notify about completion of the asynchronous process.
Each API Is deployed to multiple redundant Mule runtimes and a separate load balancer, and is deployed to a separate network zone.
In the network architecture, how must the firewall rules be configured to enable the above Interaction between API 1 and API 2?
A . To allow communication between the load balancers used by each API
B . To authorize the certificates used by both the apis
C . To enable communication from each API’s Mule runtimes and network zone to the toad balancer of the other API
D . To open direct two-way communication between the Mule runtimes of both APIs
Answer: A
