問題文
A telecom marks an order as complete in Salesforce, and a provisioning platform then has to build the circuit. Provisioning takes up to 20 minutes. The sales rep must not be held on the screen, and the provisioning platform will later send the circuit identifier back so it can be stored on the order. Which pattern should the architect record for this interface?
選択肢
- Remote Process Invocation—Request and Reply, with the callout timeout raised so that the rep's request stays open until provisioning finishes.
- UI Update Based on Data Changes, as the rep should see the order change when provisioning finishes, and that refresh is what carries the circuit identifier onto the order.
- Batch Data Synchronization, because provisioning is slow and slow work belongs in a nightly job that can retry failures the next evening without anyone having to watch it during the day.
- Remote Process Invocation—Fire and Forget, with the platform calling back afterwards to write the circuit identifier onto the order.
