MuleSoft Certified Integration Architect – Level 1 — Question 23

An integration Mule application is being designed to synchronize customer data between two systems. One system is an IBM Mainframe and the other system is a
Salesforce Marketing Cloud (CRM) instance. Both systems have been deployed in their typical configurations, and are to be invoked using the native protocols provided by Salesforce and IBM.
What interface technologies are the most straightforward and appropriate to use in this Mule application to interact with these systems, assuming that Anypoint
Connectors exist that implement these interface technologies?

Answer options

• A. IBM: DB access CRM: gRPC
• B. IBM: REST CRM: REST
• C. IBM: CICS CRM: SOAP
• D. IBM: ActiveMQ CRM: REST

Correct answer: C

Explanation

The correct answer is C because CICS (Customer Information Control System) is a transaction server that is commonly used on IBM Mainframes and is compatible with SOAP for web services. While REST is a popular choice for modern applications, it is not the best fit for IBM Mainframe integration, which often relies on CICS. The other options either do not align with the typical configurations of the systems or do not utilize the most appropriate protocols for integration.
