An organization is deploying their new implementation of the OrderStatus System API to multiple workers in CloudHub. This API fronts the organization's on-premises Order Management System, which is accessed by the API implementation over an IPsec tunnel.
What type of error typically does NOT result in a service outage of the OrderStatus System API?

• A.API Manager has an extended outage during the initial deployment of the API implementation
• B.The Order Management System is Inaccessible due to a network outage in the organization's on-premises data center
• C.The AWS region goes offline with a major network failure to the relevant AWS data centers
• D.A CloudHub worker fails with an out-of-memory exception

A large organization with an experienced central IT department is getting started using MuleSoft. There is a project to connect a siloed back-end system to a new Customer Relationship Management (CRM) system. The Center for Enablement is coaching them to use API-led connectivity.
What action would support the creation of an application network using API-led connectivity?

• A.Invite the business analyst to create a business process model to specify the canonical data model between the two systems

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

• A.The API producer should be requested to run the old version in parallel with the new one
• B.The API clients need to update the code on their side and need to do full regression
• C.The API client code only needs to be changed if it needs to take advantage of the new features
• D.The API producer should be contacted to understand the change to existing functionality
