Refer to the exhibit. An organization needs to enable access to their customer data from
both a mobile app and a web application, which each need access to common fields as
well as certain unique fields.
The data is available partially in a database and partially in a 3rd-party CRM system.
What APIs should be created to best fit these design requirements?
A.
Option A
B.
Option B
C.
Option C
D.
Option D
Option C
Explanation: Explanation
Correct Answer: Separate Experience APIs for the mobile and web app, but a common
Process API that invokes separate System APIs created for the database and CRM system
*****************************************
As per MuleSoft's API-led connectivity:
>> Experience APIs should be built as per each consumer needs and their experience.
>> Process APIs should contain all the orchestration logic to achieve the business
functionality.
>> System APIs should be built for each backend system to unlock their data.

Refer to the exhibit. An organization is running a Mule standalone runtime and has
configured Active Directory as the Anypoint Platform external Identity Provider. The organization does not have budget for other system components.
What policy should be applied to all instances of APIs in the organization to most
effecuvelyKestrict access to a specific group of internal users?
A.
Apply a basic authentication - LDAP policy; the internal Active Directory will be
configured as the LDAP source for authenticating users
B.
Apply a client ID enforcement policy; the specific group of users will configure their client applications to use their specific client credentials
C.
Apply an IP whitelist policy; only the specific users' workstations will be in the whitelist
D.
Apply an OAuth 2.0 access token enforcement policy; the internal Active Directory will be configured as the OAuth server
Apply a basic authentication - LDAP policy; the internal Active Directory will be
configured as the LDAP source for authenticating users
Explanation: Explanation
Correct Answer: Apply a basic authentication - LDAP policy; the internal Active Directory
will be configured as the LDAP source for authenticating users.
*****************************************
>> IP Whitelisting does NOT fit for this purpose. Moreover, the users workstations may not
necessarily have static IPs in the network.
>> OAuth 2.0 enforcement requires a client provider which isn't in the organizations system
components.
>> It is not an effective approach to let every user create separate client credentials and
configure those for their usage.
The effective way it to apply a basic authentication - LDAP policy and the internal Active
Directory will be configured as the LDAP source for authenticating users.

What best describes the Fully Qualified Domain Names (FQDNs), also known as DNS entries, created when a Mule application is deployed to the CloudHub Shared Worker Cloud?
A.
A fixed number of FQDNs are created, IRRESPECTIVE of the environment and VPC design
B.
The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
C.
The FQDNs are determined by the application name, but can be modified by an
administrator after deployment
D.
The FQDNs are determined by both the application name and the Anypoint Platform
organization
The FQDNs are determined by the application name chosen, IRRESPECTIVE of the region
Explanation: Explanation
Correct Answer: The FQDNs are determined by the application name chosen,
IRRESPECTIVE of the region
*****************************************
>> When deploying applications to Shared Worker Cloud, the FQDN are always
determined by application name chosen.
>> It does NOT matter what region the app is being deployed to.
>> Although it is fact and true that the generated FQDN will have the region included in it
(Ex: exp-salesorder-api.au-s1.cloudhub.io), it does NOT mean that the same name can be
used when deploying to another CloudHub region.
>> Application name should be universally unique irrespective of Region and Organization
and solely determines the FQDN for Shared Load Balancers
A company has started to create an application network and is now planning to implement a Center for Enablement (C4E) organizational model. What key factor would lead the company to decide upon a federated rather than a centralized C4E?
A.
When there are a large number of existing common assets shared by development teams
B.
When various teams responsible for creating APIs are new to integration and hence need extensive training
C.
When development is already organized into several independent initiatives or groups
D.
When the majority of the applications in the application network are cloud based
When development is already organized into several independent initiatives or groups
Explanation: Explanation
Correct Answer: When development is already organized into several independent
initiatives or groups
*****************************************
>> It would require lot of process effort in an organization to have a single C4E team
coordinating with multiple already organized development teams which are into several
independent initiatives. A single C4E works well with different teams having at least a
common initiative. So, in this scenario, federated C4E works well instead of centralized
C4E.

A company stores financial transaction data in two legacy systems. For each legacy
system, a separate, dedicated System API (SAPI) exposes data for that legacy system. A
Process API (PAPI) merges the data retrieved from ail of the System APIs into a common
format. Several API clients call the PAPI through its public domain name.
The company now wants to expose a subset of financial data to a newly developed mobile
application that uses a different Bounded Context Data Model. The company wants to
follow MuleSoft's best practices for building out an effective application network.
Following MuleSoft's best practices, how can the company expose financial data needed
by the mobile application in a way that minimizes the impact on the currently running API
clients, API implementations, and support asset reuse?
A. Add two new Experience APIs (EAPI-i and EAPI-2}.
Add Mobile PAPI-2 to expose the Intended subset of financial data as requested.
Both PAPIs access the Legacy Systems via SAPI-1 and SAP]-2.
B. Add two new Experience APIs (EAPI-i and EAPI-2}.
Add Mobile PAPI-2 to expose the Intended subset of financial data as requested.
Both PAPIs access the Legacy Systems via SAPI-1 and SAP]-2.
C. Create a new mobile Experince API (EAPI) chat exposes that subset of PAPI endpoints.
Add transformtion login to the mobile Experince API implementation to make mobile data
compatible with the required PAPIs.
D. Develop and deploy is new PAPI implementation with data transformation and ... login to
support this required endpoints of both mobile and web clients.
Deploy an API Proxy with an endpoint from API Manager that redirect the existing PAPI
endpoints to the new PAPI.
Explanation:
To achieve the goal of exposing financial data to a new mobile application while following
MuleSoft’s best practices, the company should follow an API-led connectivity approach.
This approach ensures minimal disruption to existing clients, maximizes reusability, and
respects the separation of concerns across API layers.
Explanation of Solution:
Experience APIs for Client-Specific Requirements:
Process API Layer for Data Transformation:
Reuse of System APIs:
Why Option A is Correct:
Explanation of Incorrect Options:
Option B: This option seems similar but lacks clarity on the separation of mobilespecific
requirements and does not explicitly mention data transformation, which is
essential in this scenario.
Option C: Creating a single mobile Experience API that exposes a subset of PAPI
endpoints directly adds unnecessary complexity and may violate the separation of
concerns, as transformation logic should not be in the Experience layer.
Option D: Deploying a new PAPI and using an API Proxy to redirect existing
endpoints would add unnecessary complexity, disrupt the current API clients, and
increase maintenance efforts.

For additional guidance, refer to MuleSoft documentation on API-led
connectivity best practices and best practices for structuring Experience, Process, and
System APIs.
What API policy would LEAST likely be applied to a Process API?
A.
Custom circuit breaker
B.
Client ID enforcement
C.
Rate limiting
D.
JSON threat protection
JSON threat protection
Explanation: Explanation
Correct Answer: JSON threat protection
*****************************************
Fact: Technically, there are no restrictions on what policy can be applied in what layer. Any
policy can be applied on any layer API. However, context should also be considered
properly before blindly applying the policies on APIs.
That is why, this question asked for a policy that would LEAST likely be applied to a
Process API.
From the given options:
>> All policies except "JSON threat protection" can be applied without hesitation to the
APIs in Process tier.
>> JSON threat protection policy ideally fits for experience APIs to prevent suspicious
JSON payload coming from external API clients. This covers more of a security aspect by
trying to avoid possibly malicious and harmful JSON payloads from external clients calling
experience APIs.
As external API clients are NEVER allowed to call Process APIs directly and also these
kind of malicious and harmful JSON payloads are always stopped at experience API layer
only using this policy, it is LEAST LIKELY that this same policy is again applied on Process
Layer API.
In an organization, the InfoSec team is investigating Anypoint Platform related data traffic. From where does most of the data available to Anypoint Platform for monitoring and alerting originate?
A.
From the Mule runtime or the API implementation, depending on the deployment model
B.
From various components of Anypoint Platform, such as the Shared Load Balancer, VPC, and Mule runtimes
C.
From the Mule runtime or the API Manager, depending on the type of data
D.
From the Mule runtime irrespective of the deployment model
From the Mule runtime irrespective of the deployment model
Explanation: Explanation
Correct Answer: From the Mule runtime irrespective of the deployment model
*****************************************
>> Monitoring and Alerting metrics are always originated from Mule Runtimes irrespective
of the deployment model.
>> It may seems that some metrics (Runtime Manager) are originated from Mule Runtime
and some are (API Invocations/ API Analytics) from API Manager. However, this is
realistically NOT TRUE. The reason is, API manager is just a management tool for API
instances but all policies upon applying on APIs eventually gets executed on Mule
Runtimes only (Either Embedded or API Proxy).
>> Similarly all API Implementations also run on Mule Runtimes.
So, most of the day required for monitoring and alerts are originated fron Mule Runtimes
only irrespective of whether the deployment model is MuleSoft-hosted or Customer-hosted
or Hybrid.
