Exam InsuranceSuite-Developer Topic 1 Question 87 Discussion

Managing transactions in Guidewire requires a deep understanding ofBundles. The modern and safest way to handle a transaction is using the runWithNewBundle(\ bundle -> { ... }) block (Option B).
When using runWithNewBundle, the Guidewire platform automatically handles the "Plumbing" of the transaction. It opens the bundle, provides a safe execution context, andautomatically commitsthe changes when the block reaches the end. Therefore, a critical best practice is tonever call commit() manuallyinside that block (Option F). Doing so can interfere with the platform's error-handling and post-commit logic. Option E is used for UI-bound bundles (like those in a PCF), but for background logic or integration, a fresh, managed bundle via runWithNewBundle is the gold standard for avoiding data leakage or accidental modifications.
