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

Refer to the exhibits.

Which architectural constraint is compatible with the API-led connectivity architectural style?

• A.Handle customizations for the end-user application at the Process layer rather than at the Experience layer
• B.Allow System APIs to return data that is not currently required by the identified Process or Experience APIs
  
• C.Always use a tiered approach by creating exactly one API for each of the three layers (Experience, Process, and System)
  
• D.Use a Process API to-orchestrate calls to multiple System APIs but not to other Process APIs:

A circuit breaker strategy is planned in order to meet the goal of improved response time and demand on a downstream API.
* Circuit Open: More than 10 errors per minute for three minutes
* Circuit Half-Open: One error per minute
* Circuit Closed: Less than one error per minute for five minutes
Out of several proposals from the engineering team, which option will meet this goal?

• A.Implement the strategy in a Mule application, and provide the settings in the YAML configuration
• B.Create a custom policy that implements the circuit breaker and includes policy template expressions for the required settings
• C.Add the Circuit Breaker policy to the API instance, and configure the required settings
• D.Create Anypoint Monitoring alerts for Circuit Open/Closed configurations, and then implement a retry strategy for Circuit Half-Open configuration

What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?

• A.The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
• B.A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
• C.The FQDNs are determined by the application name, but can be modified by an administrator after deployment
• D.The FQDNs are determined by both the application name and the Anypoint Platform organization

An enterprise is embarking on the API-led digital transformation journey, and the central IT team has started to define System APIs. Currently there is no Enterprise Data Model being defined within the enterprise, and the definition of a clean Bounded Context Data Model requires too much effort.
According to MuleSoft's recommended guidelines, how should the System API data model be defined?

• A.The data model of the System APIs should make use of data types that approximately mirror those from the back-end systems
• B.The System APIs should expose all back-end system fields
• C.The data model should define its own naming convention, and not follow the same naming as the back- end systems
• D.If there are misspellings of the data fields in the back-end system, Systerm APIs should not correct it, and expose it as-is to mirror the back-end systems
