Salesforce Certified MuleSoft Platform Architect Sample Questions:

1. An application updates an inventory running only one process at any given time to keep the inventory consistent. This process takes 200 milliseconds (.2 seconds) to execute; therefore, the scalability threshold of the application is five requests per second.
What is the impact on the application if horizontal scaling is applied, thereby increasing the number of Mule workers?

A) The application scalability threshold is five requests per second regardless of the horizontal scaling
B) Horizontal scaling cannot be applied to an already-running application
C) The application scalability threshold is now 10 requests per second
D) The total process execution time is now 100 milliseconds (.1 seconds)

2. An organization has created an API-led architecture that uses various API layers to integrate mobile clients with a backend system. The backend system consists of a number of specialized components and can be accessed via a REST API. The process and experience APIs share the same bounded-context model that is different from the backend data model. What additional canonical models, bounded-context models, or anti-corruption layers are best added to this architecture to help process data consumed from the backend system?

A) Create a bounded-context model for every layer and overlap them when the boundary contexts overlap, letting API developers know about the differences between upstream and downstream data models
B) Create an anti-corruption layer for every API to perform transformation for every data model to match each other, and let data simply travel between APIs to avoid the complexity and overhead of building canonical models
C) Create a bounded-context model for the system layer to closely match the backend data model, and add an anti-corruption layer to let the different bounded contexts cooperate across the system and process layers
D) Create a canonical model that combines the backend and API-led models to simplify and unify data models, and minimize data transformations.

3. A large organization with an experienced central IT department is getting started using MuleSoft. There is a project to connect a siloed back-end system to a new Customer Relationship Management (CRM) system. The Center for Enablement is coaching them to use API-led connectivity.
What action would support the creation of an application network using API-led connectivity?

A) To expedite this project, central IT should extend the CRM system and back-end systems to connect to one another using built in integration interfaces
B) Invite the business analyst to create a business process model to specify the canonical data model between the two systems
C) Create a System API to unlock the data on the back-end system using a REST API
D) Determine if the new CRM system supports the creation of custom: REST APIs, establishes 4 private network with CloudHub, and supports GAuth 2.0 authentication

4. Say, there is a legacy CRM system called CRM-Z which is offering below functions:
1. Customer creation
2. Amend details of an existing customer
3. Retrieve details of a customer
4. Suspend a customer

A) Implement different system APIs named createCustomerInCRMZ, amendCustomerInCRMZ, retrieveCustomerFromCRMZ and suspendCustomerInCRMZ as they are modular and has seperation of concerns
B) Implement a system API named customerManagement which has all the functionalities wrapped in it as various operations/resources
C) Implement different system APIs named createCustomer, amendCustomer, retrieveCustomer and suspendCustomer as they are modular and has seperation of concerns

5. What are 4 important Platform Capabilities offered by Anypoint Platform?

A) API Design and Development, API Deprecation, API Versioning, API Consumer Engagement
B) API Versioning, API Runtime Execution and Hosting, API Invocation, API Consumer Engagement
C) API Design and Development, API Runtime Execution and Hosting, API Operations and Management, API Consumer Engagement
D) API Design and Development, API Runtime Execution and Hosting, API Versioning, API Deprecation
