Exam Certified Integration Architect topic 1 question 56 discussion

Actual exam question from Salesforce's Certified Integration Architect
Question #: 56
Topic #: 1
[All Certified Integration Architect Questions]

A customer's enterprise architect has identified requirements around caching, queuing, error handling, alerts, retries, event handling, etc.
The company has asked the Salesforce Integration Architect to help fulfill such aspects with their Salesforce program.
Which three recommendations should the Salesforce integration architect make? (Choose three.)

  • A. Event handling in a publish/subscribe scenario, the middleware can be used to route requests or messages to active data-event subscribers from active data-event publishers.
  • B. Event handling processes such as writing to a log, sending an error or recovery process, or sending an extra message can be assumed to be handled by middleware.
  • C. Transform a Fire and Forget mechanism to Request and Reply, which should be handled by middleware tools (like ETL/ESB) to improve performance.
  • D. Message transformation and protocol translation should be done within Salesforce. Recommend leveraging Salesforce native protocol conversion capabilities as middleware tools are NOT suited for such tasks.
  • E. Provide true message queueing for integration scenarios (including orchestration, process choreography, quality of service, etc.) given that a middleware solution is required.

C : I don't see how SYNC is more performant than ASYNC, it is the opposite way around D : protocol conversion is not supported in SF source https://developer.salesforce.com/docs/atlas.en-us.integration_patterns_and_practices.meta/integration_patterns_and_practices/integ_pat_middleware_definitions.htm

Event handling: In a publish/subscribe scenario, the middleware can be used to route requests or messages to active data-event subscribers from active data-event publishers. Event handling processes: Processes such as writing to a log, sending an error or recovery process, or sending an extra message can be assumed to be handled by middleware. True message queueing: Provide true message queueing for integration scenarios (including orchestration, process choreography, quality of service, etc.) given that a middleware solution is required.

C: is not the best choice because transforming a Fire and Forget mechanism to a Request and Reply pattern may not necessarily improve performance. In fact, it could potentially degrade performance as it requires a response from the server for each request, which could slow down the process if there are a large number of requests.

D: is incorrect because it’s generally more efficient to handle message transformation and protocol translation in middleware tools. These tools are specifically designed to handle such tasks and can provide more flexibility and efficiency compared to doing it within Salesforce. Moreover, doing such tasks within Salesforce could add unnecessary load and complexity to the Salesforce system.

B instead of D seems obvious. Even within this same exam, the answer to the question about Shipping suppliers having slightly different Messaging structures is to use a Middleware!
