A Platform Architect inherits a legacy monolithic SOAP-based web service that performs a number of tasks, including showing all policies belonging to a client. The service connects to two back-end systems — a life-insurance administration system and a general-insurance administration system — and then queries for insurance policy information within each system, aggregates the results, and presents a SOAP-based response to a user interface (UI). The architect wants to break up the monolithic web service to follow API-led conventions. Which part of the service should be put into the process layer?


A. Combining the insurance policy information from the administration systems


B. Presenting the SOAP-based response to the UI


C. Authenticating and maintaining connections to each of the back-end administration systems


D. Querying the data from the administration systems





A.
  Combining the insurance policy information from the administration systems

Explanation:
In the API-led connectivity approach, each layer (System, Process, and Experience) has a distinct purpose:

  • System APIs: These APIs connect directly to backend systems to expose and unlock data in a standardized way.
  • Process APIs: These are responsible for orchestrating and processing data across different systems, combining information where needed.
  • Experience APIs: These are designed for specific user interfaces or applications, often transforming data formats to fit the needs of each consumer application.
Why Option A is Correct:
  • Process APIs are designed to combine data from multiple systems, which aligns with the function of aggregating policy information from both the life and general insurance systems. This aggregation logic would ideally reside in the Process layer, separating data retrieval from data orchestration.
  • Moving this functionality to the Process layer enables reusability and modularity, as other Experience APIs or services could also leverage the combined policy data if needed.
Explanation of Incorrect Options:
  • Option B (Presenting the SOAP-based response) would be managed by the Experience layer, as this layer adapts data formats for specific interfaces.
  • Option C (Authenticating and maintaining backend connections) would typically be handled within the System layer, where backend integration and security handling occurs.
  • Option D (Querying data) is the function of System APIs, which access the backend systems directly and expose the raw data without additional processing.

An organization has several APIs that accept JSON data over HTTP POST. The APIs are
all publicly available and are associated with several mobile applications and web
applications.
The organization does NOT want to use any authentication or compliance policies for these
APIs, but at the same time, is worried that some bad actor could send payloads that could
somehow compromise the applications or servers running the API implementations.
What out-of-the-box Anypoint Platform policy can address exposure to this threat?


A.

Shut out bad actors by using HTTPS mutual authentication for all API invocations


B.

Apply an IP blacklist policy to all APIs; the blacklist will Include all bad actors


C.

Apply a Header injection and removal policy that detects the malicious data before it is used


D.

Apply a JSON threat protection policy to all APIs to detect potential threat vectors





D.
  

Apply a JSON threat protection policy to all APIs to detect potential threat vectors



Explanation: Explanation
Correct Answer: Apply a JSON threat protection policy to all APIs to detect potential threat
vectors
*****************************************
>> Usually, if the APIs are designed and developed for specific consumers (known
consumers/customers) then we would IP Whitelist the same to ensure that traffic only
comes from them.
>> However, as this scenario states that the APIs are publicly available and being used by
so many mobile and web applications, it is NOT possible to identify and blacklist all
possible bad actors.
>> So, JSON threat protection policy is the best chance to prevent any bad JSON payloads
from such bad actors.

An organization makes a strategic decision to move towards an IT operating model that emphasizes consumption of reusable IT assets using modern APIs (as defined by MuleSoft). What best describes each modern API in relation to this new IT operating model?


A.

Each modern API has its own software development lifecycle, which reduces the need for documentation and automation


B.

Each modem API must be treated like a product and designed for a particular target audience (for instance, mobile app developers)


C.

Each modern API must be easy to consume, so should avoid complex authentication mechanisms such as SAML or JWT D


D.

Each modern API must be REST and HTTP based





B.
  

Each modem API must be treated like a product and designed for a particular target audience (for instance, mobile app developers)



Explanation: Explanation
Correct Answers:
1. Each modern API must be treated like a product and designed for a particular target
audience (for instance mobile app developers)

The Line of Business (LoB) of an eCommerce company is requesting a process that sends automated notifications via email every time a new order is processed through the customer's mobile application or through the internal company's web application. In the future, multiple notification channels may be added: for example, text messages and push notifications. What is the most effective API-led connectivity approach for the scenario described above?


A. Create one Experience API for the web application and one for the mobile application.
Create a Process API to orchestrate and retrieve the email template from = database.
Create a System API that sends the email using the Anypoint Connector for Email.
Create one Experience API for the web application and one for the mobile application.
Create a Process API to orchestrate and retrieve the email template from = database.
Create a System API that sends the email using the Anypoint Connector for Email.


B. Create one Experience API for the web application and one for the mobile application
Create a Process API to orchestrate, retrieve the email template from a database, and send the email using the Anypoint Connector for Email.


C. Create Experience APIs for both the web application and mobile application.
Create a Process API ta orchestrate, retrieve the email template from e database, and send the email using the Anypoint Connector for Email.


D. Create Experience APIs for both the web application and mobile application.
(Create 3 Process API to orchestrate and retrieve the email template from 2 database.
Create a System API that sends the email using the Anypoint Connector for Email.





A.
  Create one Experience API for the web application and one for the mobile application.
Create a Process API to orchestrate and retrieve the email template from = database.
Create a System API that sends the email using the Anypoint Connector for Email.
Create one Experience API for the web application and one for the mobile application.
Create a Process API to orchestrate and retrieve the email template from = database.
Create a System API that sends the email using the Anypoint Connector for Email.

Explanation:
In this scenario, the best approach to satisfy the API-led connectivity principles and support future scalability is:

  • Experience APIs:
  • Process API:
  • System API:
Why Option A is Correct:
This structure aligns with API-led connectivity principles by separating concerns across Experience, Process, and System layers. It provides flexibility for future notification channels and isolates each layer’s responsibility, making it easier to maintain and scale.
Explanation of Incorrect Options:
  • Option B lacks a separate System API for sending emails, which goes against the principle of isolating back-end functionality in System APIs.
  • Option C similarly lacks a dedicated System API, reducing flexibility and reusability.
  • Option D suggests creating multiple Process APIs for database retrieval, which adds unnecessary complexity and does not adhere to the single-orchestration principle typically followed in API-led design.

In which layer of API-led connectivity, does the business logic orchestration reside?


A.

System Layer


B.

Experience Layer


C.

Process Layer





C.
  

Process Layer



Explanation: Explanation
Correct Answer: Process Layer
*****************************************
>> Experience layer is dedicated for enrichment of end user experience. This layer is to
meet the needs of different API clients/ consumers.
>> System layer is dedicated to APIs which are modular in nature and implement/ expose
various individual functionalities of backend systems
>> Process layer is the place where simple or complex business orchestration logic is
written by invoking one or many System layer modular APIs
So, Process Layer is the right answer.
