• A.When there are a large number of existing common assets shared by development teams
• B.When various teams responsible for creating APIs are new to integration and hence need extensive training

An application updates an inventory running only one process at any given time to keep the inventory consistent. This process takes 200 milliseconds (.2 seconds) to execute; therefore, the scalability threshold of the application is five requests per second.
What is the impact on the application if horizontal scaling is applied, thereby increasing the number of Mule workers?

• A.The application scalability threshold is five requests per second regardless of the horizontal scaling
• B.The total process execution time is now 100 milliseconds (.1 seconds)
• C.The application scalability threshold is now 10 requests per second
• D.Horizontal scaling cannot be applied to an already-running application
