Salesforce Certified MuleSoft Integration Architect I

Refer to the exhibits.
An Order microservice and a Fulfillment microservice are being designed to communicate with their clients through message-based integration (and NOT through API invocations).
The Order microservice publishes an Order message (a kind of command message) containing the details of an order to be filled. The intent is that Order messages are only consumed by one Mule application: the Fulfillment microservice.
The Fulfillment microservice consumes Order messages, fills the orders described therein, and then publishes a Fulfillment message (a kind of event message). Each Fulfillment message can be consumed by any interested Mule application, and the Order microservice is one such Mule application.
What is the recommended choice of message broker(s) and message destination(s) in this scenario?

Why would an Enterprise Architect use a single enterprise-wide canonical data model (CDM) when designing an integration solution using Anypoint Platform?

An application deployed in CloudHub production environment is throwing intermittent exceptions. To troubleshoot the issue, a developer wants to enable DEBUG level logging in production for the org.apache.cxf package in the deployment Mule application.

Following MuleSoft’s recommended best practices for API governance and API policies, a project team has used RAML specifications to document and publish functional requirements and detailed design definitions of its APIs. These API specifications have been used by various stakeholders to implement APIs.
Later, the project team requires all API specifications to be augmented with an additional non-functional requirement (NFR) to protect the backend services from a high rate of requests, according to defined service-level agreements (SLAs). The NFR’s SLAs are based on a new tiered subscription level “Gold”, “Silver”, or “Platinum” that must be tied to a new parameter that is being added to the Accounts object in their enterprise data model.
Following MuleSoft’s recommended best practices, how should the project team now convey the necessary non-functional requirement to stakeholders?
