Show the answer and explanation

✓ Correct answers

Verify per-region zone redundancy and SDK preferred-region/failover configuration
Choose supported multi-write topology/consistency and conflict-resolution behavior

Multi-write requires supported consistency/conflict handling and coordinated regional/SDK resilience. Strong is incompatible with multiple write regions and serverless is single-region under the documented model. Source guide: PDF page 42.
