The three systems from the current system landscape that can be retired with the implementation of Salesforce are Case Management System, Sales Activity System, and Email Marketing System. These systems can be replaced by Salesforce Service Cloud, Sales Cloud, and Marketing Cloud respectively, which provide similar or better capabilities for managing cases, sales activities, and email campaigns. Option A is not correct because Order Management System cannot be retired with the implementation of Salesforce. The company wants to reuse their existing enterprise capabilities for order management processes, which are likely to be complex and customized. Salesforce does not provide a native order management solution for B2C commerce scenarios. Option E is not correct because Quoting System cannot be retired with the implementation of Salesforce. The company wants to reuse their existing enterprise capabilities for quoting processes, which are likely to be complex and customized. Salesforce does not provide a native quoting solution for B2C commerce scenarios.

• Answer A is valid because the Remote Process Invocation fire and forget pattern allows sending a message from Salesforce to the ERP system without waiting for a response or acknowledgement. This enables near real-time integration and reduces the latency and complexity of the integration. The Flow Builder is a low code tool that can be used to invoke an Apex action that makes the HTTP callout to the REST endpoint on insert of the order object12
• Answer C is valid because the Change Data Capture feature allows capturing changes in Salesforce data and publishing them as events to a streaming channel. The middleware can subscribe to the channel and receive the events that contain the order details. The replay Id is a unique identifier for each event that can be used by the middleware to resume from the last processed event in case of failures or interruptions. This ensures reliable and consistent integration between Salesforce and the ERP system3
• Answer B is not valid because the Outbound Messaging feature uses SOAP messages to send notifications to external systems based on workflow rules. This requires configuring a SOAP endpoint and a WSDL file for the ERP system, which may not be compatible with the REST endpoint requirement. Moreover, Outbound Messaging does not guarantee delivery or order of messages, which may affect the accuracy and timeliness of the integration.
• Answer D is not valid because the Platform Event feature allows publishing custom events from Salesforce to external systems or vice versa using a publish/subscribe model. However, this requires creating a platform event object and defining its fields and permissions, which may not be a low code solution. Moreover, using the record type as the platform event name may not be a valid or meaningful option, as record types are used to define different business processes or user interfaces for an object.

This is because Bulk API is a RESTful API that is optimized for loading or deleting large sets of data asynchronously. By processing jobs in parallel mode, you can take advantage of the multiple resources available on the Salesforce platform and speed up the data load. The other options are not suitable for this scenario because:

• B, Contact Salesforce support to schedule performance load, is not a valid option as Salesforce does not offer such a service. You are responsible for optimizing your own data load performance.
• C, Use Bulk API to process jobs in serial mode, is a slower option than parallel mode as it processes one batch at a time. This is only recommended when you have dependencies between records or when you want to preserve the order of records.
• D, Use Bulk API to process jobs in high performance mode, is not a valid option as there is no such mode in Bulk API. You can only choose between parallel and serial modes.

• 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.

• Option A is correct because using ESB (Mule) with cache/state management can help to handle the long-running requests from Salesforce and return a request ID or a response if available from the external systems. This way, Salesforce does not have to wait for the external systems to respond and can avoid the API gateway timeout1
• Option C is correct because using Continuation callouts can make the eligibility check request from Salesforce from Lightning UI at page load without blocking the UI thread. Continuation callouts are asynchronous and can handle long-running requests up to 60 seconds23
• Option E is correct because implementing a ‘Check Update’ button that passes a request ID received from ESB can allow the user to manually check the status of the eligibility check request. This can be useful when the response is not available within the Continuation timeout limit or when the user wants to refresh the data4
• Option B is incorrect because recommending synchronous Apex callouts from Lightning UI to External Systems via Mule and implementing polling on API gateway timeout can cause performance issues and user frustration. Synchronous Apex callouts block the UI thread and can only handle requests up to 120 seconds. Polling on API gateway timeout can increase the network traffic and consume the callout limits25
• Option D is incorrect because creating a Platform Event in Salesforce via Remote-Call-In and using the empAPI in the lightning UI to serve 3,000 concurrent users can introduce complexity and scalability issues. Platform Events are meant for event-driven architecture and not for request-response scenarios. Remote-Call-In requires an additional license and configuration. empAPI has a limit of 1,000 concurrent subscribers per channel678

Streaming API is the best option for sending real-time notifications of changes to Salesforce data. Streaming API uses a publish-subscribe model to push relevant data to subscribers without polling. Streaming API supports PushTopic events, which are based on SOQL queries that define the data changes to listen for. The affiliate company can subscribe to a PushTopic event on the NTO Salesforce org and receive notifications whenever the data that matches the query changes. This way, the affiliate company can be informed of any updates to the opportunities in the NTO Salesforce instance.

• Answer D is valid because using Bulk API 2.0 for both inserting and querying data can meet the requirements of loading and extracting large volumes of data in a day. Bulk API 2.0 is a RESTful API that allows creating, updating, deleting, or querying millions of records asynchronously by uploading or downloading CSV or JSON files. Bulk API 2.0 has several advantages over Bulk API 1.0, such as:
• Answer A is not valid because using Bulk API 2.0 for inserting data and REST API for querying data is not an optimal solution for handling large volumes of data in a day. REST API is a synchronous API that allows creating, updating, deleting, or querying individual records or small batches of records using HTTP methods. REST API has several limitations and drawbacks for this use case, such as:
• Answer B is not valid because using Bulk API 1.0 for both inserting and querying data is not a feasible solution for handling large volumes of data in a day. Bulk API 1.0 is a SOAP-based API that allows creating, updating, deleting, or querying millions of records asynchronously by uploading or downloading XML or CSV files. Bulk API 1.0 has several limitations and drawbacks compared to Bulk API 2.0, such as:
• Answer C is not valid because using Bulk API 1.0 for inserting data and REST API for querying data is not a suitable or reliable solution for handling large volumes of data in a day. As explained above, both Bulk API 1.0 and REST API have limitations and drawbacks that may affect the performance, efficiency, and scalability of the integration.

 Make a callout to the payment gateway through ESB supporting error handling and logging for audit purposes. This solution meets the requirements of integrating with an external RESTful service, ensuring real-time updates to the CSR, and supporting post payment processes. ESB stands for Enterprise Service Bus, which is a software architecture model that allows communication between different applications via a common bus. ESB can handle the callout to the payment gateway service, and provide error handling, logging, routing, transformation, and orchestration capabilities. ESB can also integrate with other systems or services that are involved in the post payment processes, such as billing, invoicing, or reporting.
