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
Explanation:
Version 3.0.1 of a REST API implementation represents time values in PST time using ISO 8601 hh:mm:ss format. The API implementation needs to be changed to instead represent time values in CEST time using ISO 8601 hh:mm:ss format. When following the semver.org semantic versioning specification, what version should be assigned to the updated API implementation?
A.
3.0.2
B.
4.0.0
C.
3.1.0
D.
3.0.1
4.0.0
Explanation: Explanation
Correct Answer: 4.0.0
*****************************************
As per semver.org semantic versioning specification:
Given a version number MAJOR.MINOR.PATCH, increment the:
- MAJOR version when you make incompatible API changes.
- MINOR version when you add functionality in a backwards compatible manner.
- PATCH version when you make backwards compatible bug fixes.
As per the scenario given in the question, the API implementation is completely changing
its behavior. Although the format of the time is still being maintained as hh:mm:ss and there
is no change in schema w.r.t format, the API will start functioning different after this change
as the times are going to come completely different.
Example: Before the change, say, time is going as 09:00:00 representing the PST. Now on,
after the change, the same time will go as 18:00:00 as Central European Summer Time is
9 hours ahead of Pacific Time.
>> This may lead to some uncertain behavior on API clients depending on how they are
handling the times in the API response. All the API clients need to be informed that the API
functionality is going to change and will return in CEST format. So, this considered as a
MAJOR change and the version of API for this new change would be 4.0.0
What is a best practice when building System APIs?
A.
Document the API using an easily consumable asset like a RAML definition
B.
Model all API resources and methods to closely mimic the operations of the backend system
C.
Build an Enterprise Data Model (Canonical Data Model) for each backend system and apply it to System APIs
D.
Expose to API clients all technical details of the API implementation's interaction wifch
the backend system
Model all API resources and methods to closely mimic the operations of the backend system
Explanation: Explanation
Correct Answer: Model all API resources and methods to closely mimic the operations of
the backend system.
*****************************************
>> There are NO fixed and straight best practices while opting data models for APIs. They
are completly contextual and depends on number of factors. Based upon those factors, an
enterprise can choose if they have to go with Enterprise Canonical Data Model or Bounded
Context Model etc.
>> One should NEVER expose the technical details of API implementation to their API
clients. Only the API interface/ RAML is exposed to API clients.
>> It is true that the RAML definitions of APIs should be as detailed as possible and should
reflect most of the documentation. However, just that is NOT enough to call your API as
best documented API. There should be even more documentation on Anypoint Exchange
with API Notebooks etc. to make and create a developer friendly API and repository..
>> The best practice always when creating System APIs is to create their API interfaces by
modeling their resources and methods to closely reflect the operations and functionalities
of that backend system.
An auto manufacturer has a mature CI/CD practice and wants to automate packaging and deployment of any Mule applications to various deployment targets, including CloudHub workers/replicas, customer-hosted Mule runtimes, and Anypoint Runtime Fabric. Which MuleSoft-provided tool or component facilitates automating the packaging and deployment of Mule applications to various deployment targets as part of the company's CI/CD practice?
A. Anypoint Runtime Manager
B. Mule Maven plugin
C. Anypoint Platform CLI
D. Anypoint Platform REST APIs
Explanation:
For organizations with established CI/CD practices, the Mule Maven plugin
is the recommended tool for automating packaging and deployment across multiple
environments, including CloudHub, on-premise Mule runtimes, and Anypoint Runtime
Fabric. Here’s why:
An API has been updated in Anypoint Exchange by its API producer from version 3.1.1 to
3.2.0 following accepted semantic versioning practices and the changes have been
communicated via the API's public portal.
The API endpoint does NOT change in the new version.
How should the developer of an API client respond to this change?
A.
The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run
B.
The API producer should be contacted to understand the change to existing functionality
C.
The API producer should be requested to run the old version in parallel with the new one
D.
The API client code ONLY needs to be changed if it needs to take advantage of new
features
The API client code ONLY needs to be changed if it needs to take advantage of new
features

Explanation: Explanation
Correct Answer: XML over HTTP
*****************************************
>> API-led connectivity and Application Networks urge to have the APIs on HTTP based
protocols for building most effective APIs and networks on top of them.
>> The HTTP based APIs allow the platform to apply various varities of policies to address
many NFRs
>> The HTTP based APIs also allow to implement many standard and effective
implementation patterns that adhere to HTTP based w3c rules
The asset version 2.0.0 of the Order API is successfully published in Exchange and configured in API Manager with the Autodiscovery API ID correctly linked to the API implementation, A new GET method is added to the existing API specification, and after updates, the asset version of the Order API is 2.0.1. What happens to the Autodiscovery API ID when the new asset version is updated in API Manager?
A. The API ID changes, but no changes are needed to the API implementation for the new asset version in the API Autediscovery global element because the API ID is automatically updated
B. The APL ID changes, so the API implementation must be updated with the latest API ID for the new asset version in the API Autodiscovery global element
C. The APLID does not change, so no changes to the APT implementation are needed for the new asset version in the API Autodiscovery global element
D. The APL ID does not change, but the API implementation must be updated in the AP] Autodiscovery global element to indicate the new asset version 2.0.4

Evaluating the Options:
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
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.
