Salesforce Certified MuleSoft Platform Architect Sample Questions:

1. 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) In-memory Mule Object Store
B) Non-persistent Object Store
C) Persistent Object Store
D) Runtime Fabric Object Store

2. A company requires Mule applications deployed to CloudHub to be isolated between non-production and production environments. This is so Mule applications deployed to non-production environments can only access backend systems running in their customer-hosted non-production environment, and so Mule applications deployed to production environments can only access backend systems running in their customer-hosted production environment. How does MuleSoft recommend modifying Mule applications, configuring environments, or changing infrastructure to support this type of per-environment isolation between Mule applications and backend systems?

A) Configure firewall rules in the infrastructure inside each customer-hosted environment so that only IP addresses from the corresponding Anypoint Platform environments are allowed to communicate with corresponding backend systems
B) Modify properties of Mule applications deployed to the production Anypoint Platform environments to prevent access from non-production Mule applications
C) Create non-production and production environments in different Anypoint Platform business groups
D) Create separate Anypoint VPCs for non-production and production environments, then configure connections to the backend systems in the corresponding customer-hosted environments

3. 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 API client code ONLY needs to be changed if it needs to take advantage of new features
B) The API producer should be requested to run the old version in parallel with the new one
C) The API producer should be contacted to understand the change to existing functionality
D) The update should be identified as a project risk and full regression testing of the functionality that uses this API should be run

4. 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.

5. When must an API implementation be deployed to an Anypoint VPC?

A) When the API Implementation must write to a persistent Object Store
B) When the API implementation must be accessible within a subnet of a restricted customer-hosted network that does not allow public access
C) When the API implementation must be deployed to a production AWS VPC using the Mule Maven plugin
D) When the API Implementation must invoke publicly exposed services that are deployed outside of CloudHub in a customer- managed AWS instance
