A developer is building a client application to invoke an API deployed to the STAGING
environment that is governed by a client ID enforcement policy.
What is required to successfully invoke the API?


A.

The client ID and secret for the Anypoint Platform account owning the API in the STAGING environment


B.

The client ID and secret for the Anypoint Platform account's STAGING environment


C.

The client ID and secret obtained from Anypoint Exchange for the API instance in the
STAGING environment


D.

A valid OAuth token obtained from Anypoint Platform and its associated client ID and
secret





C.   

The client ID and secret obtained from Anypoint Exchange for the API instance in the
STAGING environment



Explanation: Explanation
Correct Answer: The client ID and secret obtained from Anypoint Exchange for the API
instance in the STAGING environment
*****************************************
>> We CANNOT use the client ID and secret of Anypoint Platform account or any individual
environments for accessing the APIs
>> As the type of policy that is enforced on the API in question is "Client ID Enforcment
Policy", OAuth token based access won't work.
Right way to access the API is to use the client ID and secret obtained from Anypoint
Exchange for the API instance in a particular environment we want to work on.

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

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.

  • DNS Configuration with CNAME:
  • Why Option B is Correct:
  • Explanation of Incorrect Options:

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

4A developer for a transportation organization is implementing exactly one processing functionality in a Reservation Mule application to process and store passenger records. This Reservation application will be deployed to multiple CloudHub workers/replicas. It is possible that several external systems could send duplicate passenger records to the Reservation application.
An appropriate storage mechanism must be selected to help the Reservation application process each passenger record exactly once as much as possible. The selected storage mechanism must be shared by all the CloudHub workers/replicas in order to synchronize the state information to assist attempting exactly once processing of each passenger record by the deployed Reservation Mule application.
Which type of simple storage mechanism in Anypoint Platform allows the Reservation Mule application to update and share data between the CloudHub workers/replicas exactly once, with minimal development effort?


A. Persistent Object Store


B. Runtime Fabric Object Store


C. Non-persistent Object Store


D. In-memory Mule Object Store





A.   Persistent Object Store


What Mule application deployment scenario requires using Anypoint Platform Private Cloud Edition or Anypoint Platform for Pivotal Cloud Foundry?


A.

When it Is required to make ALL applications highly available across multiple data centers


B.

When it is required that ALL APIs are private and NOT exposed to the public cloud


C.

When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data


D.

When ALL backend systems in the application network are deployed in the
organization's intranet





C.   

When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data



Explanation: Explanation
Correct Answer: When regulatory requirements mandate on-premises processing of EVERY data item, including meta-data.
*****************************************
We need NOT require to use Anypoint Platform PCE or PCF for the below. So these
options are OUT.
>> We can make ALL applications highly available across multiple data centers using
CloudHub too.
>> We can use Anypoint VPN and tunneling from CloudHub to connect to ALL backend
systems in the application network that are deployed in the organization's intranet.
>> We can use Anypoint VPC and Firewall Rules to make ALL APIs private and NOT
exposed to the public cloud.
Only valid reason in the given options that requires to use Anypoint Platform PCE/ PCF is -
When regulatory requirements mandate on-premises processing of EVERY data item,
including meta-data

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)



A company has created a successful enterprise data model (EDM). The company is
committed to building an application network by adopting modern APIs as a core enabler of
the company's IT operating model. At what API tiers (experience, process, system) should
the company require reusing the EDM when designing modern API data models?


A.

At the experience and process tiers


B.

At the experience and system tiers


C.

At the process and system tiers


D.

At the experience, process, and system tiers





C.   

At the process and system tiers



Explanation: Explanation Correct Answer: At the process and system tiers
*****************************************
>> Experience Layer APIs are modeled and designed exclusively for the end user's
experience. So, the data models of experience layer vary based on the nature and type of
such API consumer. For example, Mobile consumers will need light-weight data models to
transfer with ease on the wire, where as web-based consumers will need detailed data
models to render most of the info on web pages, so on. So, enterprise data models fit for
the purpose of canonical models but not of good use for experience APIs.
>> That is why, EDMs should be used extensively in process and system tiers but NOT in
experience tier.
