Salesforce Integration-Architect Exam With Confidence Using Practice Dumps

Option B is correct because platform events are published after the Apex transaction completes. Platform events are asynchronous messages that are published and consumed by different processes or systems. When an Apex transaction publishes a platform event, the event is not sent immediately, but rather added to a temporary queue. The event is only published and delivered to the subscribers after the Apex transaction commits successfully. This ensures that the event data is consistent with the database state and that the event is not lost in case of a rollback.

Option A is incorrect because platform events are not published immediately before the Apex transaction completes. As explained above, platform events are published after the Apex transaction commits successfully. Publishing events before the transaction completes can cause data inconsistency and event loss issues.

Option C is incorrect because platform events can have a trigger in Apex, but this is not related to the question of when events are published. A platform event trigger is a special type of Apex trigger that executes when a platform event message is received by Salesforce. A platform event trigger can perform logic based on the event data, such as updating records, sending notifications, or calling external services. A platform event trigger does not affect the publishing of events, but rather the consumption of events.

Option D is incorrect because platform events can be published from Apex, but this does not answer the question of when events are published. Platform events can be published from various sources, such as Apex code, Process Builder, Flows, or API calls. Publishing events from Apex requires creating an instance of a platform event object and using the EventBus.publish method to add it to the temporary queue. The actual publishing of events happens after the Apex transaction completes, regardless of the source of the events.

Leveraging Middleware for all back-office system integrations ensuring real time alerting, monitoring and reporting capabilities is the best integration solution for this scenario.Middleware is a software layer that acts as an intermediary between Salesforce and other systems, providing a common platform for data transformation, routing, orchestration, security, error handling, logging, and monitoring. Middleware can help to ensurereliability and performance of the integrations, as well as provide visibility and control over the integration processes. Middleware can also support various integration patterns and protocols, such as SOAP, REST, JMS, etc. Reference: Salesforce Integration Architecture Designer Resource Guide, page 14

Remote Site Settings and Named Credentials are solutions that should be implemented to minimize potential downtime for users in this situation. Remote Site Settings allow you to specify external domains that your organization can access during API calls or integrations. Named Credentials allow you to store authentication information for external services in a secure way. By using Named Credentials, you can easily update the URL of the external service without changing any code or configuration that references it. Enterprise Service Bus (ESB) and Remote Site Settings are not solutions that should be implemented in this situation because ESB is a middleware that facilitates communication between different systems, not a way to update the URL of an external service. Event Monitoring and Content Security Policies are also not solutions that should be implemented in this situation because Event Monitoring is used to track user activity and performance metrics, not to monitor external service availability. Content Security Policies are used to control what resources can be loaded on a web page, not to update the URL of an external service.
