An Order API triggers a sequence of other API calls to look up details of an order's items in a back-end inventory database. The Order API calls the OrderItems process API, which calls the Inventory system API. The Inventory system API performs database operations in the back-end inventory database.
The network connection between the Inventory system API and the database is known to be unreliable and hang at unpredictable times.
Where should a two-second timeout be configured in the API processing sequence so that the Order API never waits more than two seconds for a response from the Orderltems process API?


A. In the Orderltems process API implementation


B. In the Order API implementation


C. In the Inventory system API implementation


D. In the inventory database





A.
  In the Orderltems process API implementation

A Mule 4 API has been deployed to CloudHub and a Basic Authentication - Simple policy has been applied to all API methods and resources. However, the API is still accessible by clients without using authentication. How is this possible?


A. The APE Router component is pointing to the incorrect Exchange version of the APT


B. The Autodiscovery element is not present, in the deployed Mule application


C. No… for client applications have been created of this API


D. One of the application’s CloudHub workers restarted





B.
  The Autodiscovery element is not present, in the deployed Mule application

Explanation:
When a Basic Authentication policy is applied to an API on CloudHub but clients can still access the API without authentication, the likely cause is a missing Autodiscovery element. Here’s how this affects API security:

  • Autodiscovery in MuleSoft:
  • Why Option B is Correct:
  • Explanation of Incorrect Options:
References:
Refer to MuleSoft documentation on Autodiscovery configuration and linking API Manager policies for additional information on setting up secure API policies.

Which of the following sequence is correct?


A.

API Client implementes logic to call an API >> API Consumer requests access to API >>
API Implementation routes the request to >> API


B.

API Consumer requests access to API >> API Client implementes logic to call an API >>
API routes the request to >> API Implementation


C.

API Consumer implementes logic to call an API >> API Client requests access to API >>
API Implementation routes the request to >> API


D.

API Client implementes logic to call an API >> API Consumer requests access to API >>
API routes the request to >> API Implementation





B.
  

API Consumer requests access to API >> API Client implementes logic to call an API >>
API routes the request to >> API Implementation



Explanation: Explanation
Correct Answer: API Consumer requests access to API >> API Client implementes logic to
call an API >> API routes the request to >> API Implementation
*****************************************
>> API consumer does not implement any logic to invoke APIs. It is just a role. So, the
option stating "API Consumer implementes logic to call an API" is INVALID.
>> API Implementation does not route any requests. It is a final piece of logic where
functionality of target systems is exposed. So, the requests should be routed to the API
implementation by some other entity. So, the options stating "API Implementation routes
the request to >> API" is INVALID
>> The statements in one of the options are correct but sequence is wrong. The sequence
is given as "API Client implementes logic to call an API >> API Consumer requests access
to API >> API routes the request to >> API Implementation". Here, the statements in the
options are VALID but sequence is WRONG.
>> Right option and sequence is the one where API consumer first requests access to API
on Anypoint Exchange and obtains client credentials. API client then writes logic to call an
API by using the access client credentials requested by API consumer and the requests will
be routed to API implementation via the API which is managed by API Manager

A large company wants to implement IT infrastructure in its own data center, based on the corporate IT policy requirements that data and metadata reside locally. Which combination of Mule control plane and Mule runtime plane(s) meets the requirements?


A. Anypoint Platform Private Cloud Edition for the control plane and the MuleSoft-hosted runtime plane


B. The MuleSoft-hosted control plane and Anypoint Runtime Fabric for the runtime plane


C. The MuleSoft-hosted control plane and customer-hosted Mule runtimes for the runtime plane


D. Anypoint Platform Private Cloud Edition for the control plane and customer-hosted Mule runtimes for the runtime plane





D.
  Anypoint Platform Private Cloud Edition for the control plane and customer-hosted Mule runtimes for the runtime plane

Explanation:

  • Understanding Control and Runtime Planes
  • Evaluating the Options
Conclusion:
Refer to MuleSoft's documentation on Private Cloud Edition deployment and on-premise runtime configurations for further details.

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 request definitions by adding a remaining Requests query parameter with description, type, and example


C.

By refining the response definitions by adding the out-of-the-box Anypoint Platform ratelimit-
enforcement securityScheme with description, type, and example


D.

By refining the response definitions by adding the x-ratelimit-* response headers with
description, type, and example





D.
  

By refining the response definitions by adding the x-ratelimit-* response headers with
description, type, and example



Explanation: Explanation
Correct Answer: By refining the response definitions by adding the x-ratelimit-* response
headers with description, type, and example
*****************************************

A business process is being implemented within an organization's application network. The architecture group proposes using a more coarse-grained application network design with relatively fewer APIs deployed to the application network compared to a more fine-grained design. Overall, which factor typically increases with a more coarse-grained design for this business process implementation and deployment compared with using a more finegrained design?


A. The complexity of each API implementation


B. The number of discoverable assets related to APIs deployed in the application network


C. The number of possible connections between API implementations in the application network


D. The usage of network infrastructure resources by the application network





A.
  The complexity of each API implementation

An operations team is analyzing the effort needed to set up monitoring of their application network. They are looking at which API invocation metrics can be used to identify and predict trouble without having to write custom scripts or install additional analytics software or tools. Which type of metrics can satisfy this goal of directly identifying and predicting failures?


A. The number and types of API policy violations per day


B. The effectiveness of the application network based on the level of reuse


C. The number and types of past API invocations across the application network


D. The ROI from each APT invocation





A.
  The number and types of API policy violations per day

Explanation:
To monitor an application network and predict issues without custom scripts, policy violation metrics are critical. They provide insights into potential problems by tracking instances where API usage does not conform to defined policies. Here’s why this approach is suitable:

  • Predictive Monitoring:
  • No Custom Scripting Needed:
  • Explanation of Incorrect Options:

A REST API is being designed to implement a Mule application.
What standard interface definition language can be used to define REST APIs?


A.

Web Service Definition Language(WSDL)


B.

OpenAPI Specification (OAS)


C.

YAML


D.

AsyncAPI Specification





B.
  

OpenAPI Specification (OAS)
