• Option C is correct because including selective criteria in query filters can improve the performance of the integration. Selective criteria are filters that reduce the number of records that need to be scanned by the query optimizer, such as indexed fields, standard indexes, or custom indexes. Selective criteria can help the query run faster and avoid hitting the query timeout limit or the query row limit.
• Option D is correct because removing the sharing restrictions can improve the performance of the integration. Sharing restrictions are filters that limit the access to records based on the user’s role, profile, or sharing rules. Sharing restrictions can add complexity and overhead to the query execution, as they require additional joins and calculations. Removing the sharing restrictions can simplify the query and reduce the number of records that need to be processed.
• Option A is incorrect because including non-selective criteria in query filters can degrade the performance of the integration. Non-selective criteria are filters that do not reduce the number of records that need to be scanned by the query optimizer, such as non-indexed fields, formula fields, or OR conditions. Non-selective criteria can cause the query to run slower and hit the query timeout limit or the query row limit.
• Option B is incorrect because removing the query filters can degrade the performance of the integration. Query filters are conditions that specify which records to retrieve from the database, such as WHERE clauses or LIMIT clauses. Query filters can help the query run faster and avoid retrieving unnecessary or unwanted data. Removing the query filters can increase the number of records that need to be processed and transmitted by the integration.

The correct answer is C, Request-Reply: Enhanced External Services invokes a REST API. This is because Enhanced External Services allows you to register an external web service that has an OpenAPI 2.0 specification and use it as an invocable action in a Lightning flow. This way, you can check the preferences from the external service in real-time and get the response in Boolean and string values. The other options are not suitable for this scenario because:

• A, Fire and Forget: Process-driven platform events publishes events on Salesforce Event Bus, is a pattern that is used for asynchronous integration, where the sender does not expect a response from the receiver. This is not suitable for checking preferences in real-time.
• B, Remote Call-In: Salesforce REST API with REST Composite Resources, is a pattern that is used for integrating external applications with Salesforce by calling the Salesforce REST API. This is not suitable for invoking an external service from a Lightning flow.
• D, Data Virtualization: Salesforce Connect map data external REST data in external objects, is a pattern that is used for accessing external data without copying or synchronizing it to Salesforce. This is not suitable for checking preferences in real-time or using them in a Lightning flow.

Using request and reply is the recommended integration pattern for this use case because it allows the support agents to send a request to the core banking system and receive a response with the bank account ID in real-time. This way, the support agents can inform the customers with the newly created bank account ID without any delay or inconsistency. Using streaming API to generate push topic is not a good solution because it is used for event-driven integration, not for web-service integration. Using outbound message is also not a good solution because it is a Salesforce-specific feature that uses SOAP web services, which may not be compatible with the core banking system. Using Salesforce platform event is also not a good solution because it is used for event-driven integration, not for web-service integration.
