How can the application of a rate limiting API policy be accurately reflected in the RAML definition of an API?

• A.By refining the resource definitions by adding a description of the rate limiting policy behavior
• B.By refining the response definitions by adding the x-ratelimit-* response headers with description, type, and example
• C.By refining the request definitions by adding a remaining Requests query parameter with description, type, and example
• D.By refining the response definitions by adding the out-of-the-box Anypoint Platform rate-limit- enforcement securityScheme with description, type, and example

Refer to the exhibit. An organization needs to enable access to their customer data from both a mobile app and a web application, which each need access to common fields as well as certain unique fields.
The data is available partially in a database and partially in a 3rd-party CRM system.
What APIs should be created to best fit these design requirements?

A) A Process API that contains the data required by both the web and mobile apps, allowing these applications to invoke it directly and access the data they need thereby providing the flexibility to add more fields in the future without needing API changes B) One set of APIs (Experience API, Process API, and System API) for the web app, and another set for the mobile app C) Separate Experience APIs for the mobile and web app, but a common Process API that invokes separate System APIs created for the database and CRM system

D) A common Experience API used by both the web and mobile apps, but separate Process APIs for the web and mobile apps that interact with the database and the CRM System

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

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

An API implementation is updated. When must the RAML definition of the API also be updated?

• A.When the API implementation changes from interacting with a legacy backend system deployed on- premises to a modern, cloud-based (SaaS) system
• B.When the API implementation is optimized to improve its average response time
• C.When the API implementation changes the structure of the request or response messages
• D.When the API implementation is migrated from an older to a newer version of the Mule runtime

An organization has built an application network following the API-led connectivity approach recommended by MuleSoft. To protect the application network against attacks from malicious external API clients, the organization plans to apply JSON Threat Protection policies.
To which API-led connectivity layer should the JSON Threat Protection policies most commonly be applied?

• A.Process layer
• B.All layers
• C.System layer
• D.Experience layer
