SLM Integration Design 2 — Questions and Answers
Question 1: Which Salesforce integration pattern is best suited for real-time loyalty point accrual from a POS system that requires an immediate response?
- Request and Reply (Correct answer)
- Fire and Forget
- Batch Data Synchronization
- UI Update Based on Data Changes
Correct answer: Request and Reply
Request and Reply is ideal when the calling system needs an immediate synchronous response, such as confirming point accrual at checkout.
Question 2: A loyalty platform needs to push real-time tier upgrade events to an external CRM without waiting for a response. Which pattern best fits this scenario?
- Request and Reply
- Fire and Forget (Correct answer)
- Batch Data Synchronization
- Remote Call-In
Correct answer: Fire and Forget
Fire and Forget sends the event asynchronously and does not wait for a reply, ideal for notifications like tier upgrades.
Question 3: Which Salesforce feature allows an external system to subscribe to loyalty member tier change events without polling the Salesforce API?
- Outbound Messages
- Platform Events (Correct answer)
- Scheduled Apex
- Salesforce Connect
Correct answer: Platform Events
Platform Events enable event-driven integration where external systems subscribe to events published by Salesforce, eliminating the need for polling.
Question 4: When integrating Loyalty Management with an external marketing platform, which authentication mechanism is the Salesforce-recommended standard for securing API-to-API calls?
- Basic Authentication
- OAuth 2.0 Client Credentials Flow (Correct answer)
- API Key in URL parameter
- Session ID sharing
Correct answer: OAuth 2.0 Client Credentials Flow
OAuth 2.0 Client Credentials Flow is the recommended server-to-server authentication mechanism that does not require user interaction.
Question 5: A company wants to display loyalty points from Salesforce on a third-party portal without replicating data. Which Salesforce feature enables this?
- External Objects via Salesforce Connect (Correct answer)
- Data Loader export
- Change Data Capture
- Apex callouts
Correct answer: External Objects via Salesforce Connect
Salesforce Connect uses External Objects to display data from external systems in real time without storing it in Salesforce.
Question 6: Which Salesforce tool provides a low-code way to call an external REST API and map its response to Salesforce fields within a Flow?
- Apex HTTP Callout
- External Services (Correct answer)
- Named Credentials
- MuleSoft Anypoint
Correct answer: External Services
External Services allows admins to register an external REST API and invoke it declaratively within Flows without writing code.
Question 7: When configuring a Named Credential for a loyalty integration, what is the primary security benefit over storing credentials in Custom Settings?
- Named Credentials support multiple authentication protocols
- Credentials are encrypted and not exposed in Apex code or logs (Correct answer)
- Named Credentials allow more API calls per day
- They automatically retry failed callouts
Correct answer: Credentials are encrypted and not exposed in Apex code or logs
Named Credentials store authentication details securely so they are never exposed in Apex code, debug logs, or setup fields.
