Exam Certified Integration Architect topic 1 question 65 discussion

Because of the "real-time" requirement, the answer is B. Why? Streaming API is specifically designed for real-time notifications and event-driven communication. It allows Salesforce to subscribe to event channels and receive updates when the quoting system sends maintenance alerts. This is ideal because all sales representatives using Salesforce need to be notified automatically and instantly when maintenance is scheduled. This eliminates the need for users to manually check for updates. Why Not A. Connect REST API? Connect REST API is used to access Salesforce UI components and Chatter data externally. While it allows integrations with external systems, it is not optimized for real-time notifications. If NTO were pulling maintenance messages on-demand, this could work, but the question specifies that notifications should be pushed to users in Salesforce.

Unlike REST API or Tooling API, Streaming API uses a push model, meaning Salesforce doesn’t need to constantly query for updates.

it seems like half an answer - it's the realtime alert, but you also need a UI component

The correct answer is A. Connect REST API. Salesforce’s Connect REST API can be used to send custom notifications to recipients via desktop or mobile channels. Before sending a custom notification, a notification type must first be created. This would be the most suitable option for notifying all sales representatives about the maintenance of the quoting system. Streaming API can be useful for applications that need to monitor or react to changes in data, such as live chat, stock prices, or social media updates. However, Streaming API also has some limitations and challenges, such as: Complexity, Compatibility and Cost
