Your team is deciding which upcoming tasks should start in plan mode and which can go straight to direct execution. Which two tasks are the best candidates for plan mode? Select two.

Answer: B and D — Migrating the data-access layer from one ORM library to another, a change that touches about 50 files and requires decisions about transaction handling along the way. / Choosing between a webhook-based and a queue-based integration with a partner system, where each option has different infrastructure and failure-handling requirements.

Plan mode is for complex work: large multi-file changes, architectural decisions, and choices between valid approaches with different infrastructure requirements. That makes the ORM migration (b) and the integration-approach decision (d) good fits, and both can then move to direct execution once the plan is set (task 3.4). The single-function fix with a clear stack trace (a) and the single date-validation conditional (c) are well-scoped changes where direct execution is appropriate and planning only adds overhead.
