What is the best way to decompose one end-to-end business process into a collaboration of Experience, Process, and System APIs?
A) Handle customizations for the end-user application at the Process API level rather than the Experience API level
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 3 layers (Experience, Process and System APIs)
D) Use a Process API to orchestrate calls to multiple System APIs, but NOT to other Process APIs


A. Option A


B. Option B


C. Option C


D. Option D





B.   Option B

Explanation:
Correct Answer: Allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs.

  • All customizations for the end-user application should be handled in "Experience API" only. Not in Process API
  • We should use tiered approach but NOT always by creating exactly one API for each of the 3 layers. Experience APIs might be one but Process APIs and System APIs are often more than one. System APIs for sure will be more than one all the time as they are the smallest modular APIs built in front of end systems.
  • Process APIs can call System APIs as well as other Process APIs. There is no such anti-design pattern in API-Led connectivity saying Process APIs should not call other Process APIs.
So, the right answer in the given set of options that makes sense as per API-Led connectivity principles is to allow System APIs to return data that is NOT currently required by the identified Process or Experience APIs. This way, some future Process APIs can make use of that data from System APIs and we need NOT touch the System layer APIs again and again.

When can CloudHub Object Store v2 be used?


A. To store an unlimited number of key-value pairs


B. To store payloads with an average size greater than 15MB


C. To store information in Mule 4 Object Store v1


D. To store key-value pairs with keys up to 300 characters





D.   To store key-value pairs with keys up to 300 characters

Explanation: CloudHub Object Store v2 is a managed key-value store provided by MuleSoft to support various use cases where temporary data storage is required. Here’s why Option D is correct:
Key Length Support: Object Store v2 allows storage of keys with a length of up to 300 characters, making it suitable for applications needing flexible and descriptive keys.
Limitations on Size:
Key-Value Limits: Object Store v2 is designed for moderate, transient storage needs, and does not support unlimited storage. Thus, Option A is incorrect.
Backward Compatibility: Object Store v2 does not support Mule 4 applications running Object Store v1. Option C is incorrect as Object Store v1 and v2 are distinct.

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


A.

When the API implementation changes the structure of the request or response messages


B.

When the API implementation changes from interacting with a legacy backend system deployed on-premises to a modern, cloud-based (SaaS) system


C.

When the API implementation is migrated from an older to a newer version of the Mule runtime


D.

When the API implementation is optimized to improve its average response time





A.   

When the API implementation changes the structure of the request or response messages



Explanation: Explanation
Correct Answer: When the API implementation changes the structure of the request or
response messages
*****************************************
>> RAML definition usually needs to be touched only when there are changes in the
request/response schemas or in any traits on API.
>> It need not be modified for any internal changes in API implementation like performance
tuning, backend system migrations etc

A TemperatureSensors API instance is defined in API Manager in the PROD environment of the CAR_FACTORY business group. An AcmelemperatureSensors Mule application implements this API instance and is deployed from Runtime Manager to the PROD environment of the CAR_FACTORY business group. A policy that requires a valid client ID and client secret is applied in API Manager to the API instance.
Where can an API consumer obtain a valid client ID and client secret to call the AcmeTemperatureSensors Mule application?


A. In secrets manager, request access to the Shared Secret static username/password


B. In API Manager, from the PROD environment of the CAR_FACTORY business group


C. In access management, from the PROD environment of the CAR_FACTORY business group


D. In Anypoint Exchange, from an API client application that has been approved for the TemperatureSensors API instance





D.   In Anypoint Exchange, from an API client application that has been approved for the TemperatureSensors API instance

Explanation:
When an API policy requiring a client ID and client secret is applied to an API instance in API Manager, API consumers must obtain these credentials through a registered client application. Here’s how it works:

  • Anypoint Exchange and Client Applications:
  • Why Option D is Correct:
  • Explanation of Incorrect Options:

An established communications company is beginning its API-led connectivity journey, The company has been using a successful Enterprise Data Model for many years. The company has identified a self-service account management app as the first effort for APIled, and it has identified the following APIs.

  • Experience layer: Mobile Account Management EAPI, Browser Account Management EAPI
  • Process layer: Customer Lookup PAPI, Service Lookup PAPI, Account Lookup PAPI
  • System layer: Customer SAPI, Account SAPI, Product SAPI, Service SAPI
According to MuleSoft's API-led connectivity approach, which API would not be served by the Enterprise Data Model?


A. Customer SAPI


B. Customer Lookup PAPI


C. Mobile Account Management EAPI


D. Service SAPI





C.   Mobile Account Management EAPI

Explanation: In the API-led connectivity approach, APIs are categorized into Experience, Process, and System layers:

A customer wants to host their MuleSoft applications in CloudHub 1.0, and these applications should be available at the domain https://api.acmecorp.com.
After creating a dedicated load balancer (DLB) called acme-dib-prod, which further action must the customer take to complete the configuration?


A. Configure the DLB with a TLS certificate for api.acmecorp.com and create an A record for api.acmecorp.com to the public IP addresses associated with their DLB


B. Configure the DLB with a TLS certificate for api.acmecorp.com and create a CNAME record from api.acmecorp.com to acme-dib-prod.|lb.anypointdns.net


C. Configure the DLB with a TLS certificate for acme-dib-prod.Jb.anypointdns.net and create a CNAME record from api.acmecorp:com to acme-dlb-prod.lb.anypointdns.net


D. Configure the DLB with a TLS certificate for aplacmecorp.com and create a CNAME record from api.aomecorp.com to acme-dib-prod.ei.cloubhub.io





B.   Configure the DLB with a TLS certificate for api.acmecorp.com and create a CNAME record from api.acmecorp.com to acme-dib-prod.|lb.anypointdns.net

Explanation:
When setting up a custom domain for MuleSoft applications hosted on CloudHub 1.0 using a Dedicated Load Balancer (DLB), follow these steps:
Set Up the TLS Certificate: Configure the DLB (acme-dib-prod) with a TLS certificate that covers the custom domain api.acmecorp.com. This certificate will allow HTTPS traffic to be securely directed through the DLB to your Mule applications.

  • Why Option B is Correct:
  • Explanation of Incorrect Options:

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 application scalability threshold is five requests per second regardless of the horizontal scaling


B. The total process execution time is now 100 milliseconds (.1 seconds)


C. The application scalability threshold is now 10 requests per second


D. Horizontal scaling cannot be applied to an already-running application





A.   The application scalability threshold is five requests per second regardless of the horizontal scaling

Explanation:
Given that the application is designed to handle only one process at a time to maintain data consistency, here’s why horizontal scaling won’t increase the processing limit:
