What approach supports bulk updates of addresses?

• A. Provide bulk endpoints or batch jobs
• B. Use chunked processing and idempotent operations
• C. Provide per-record reporting of results
• D. All of the above

Answer: (D)

Handling bulk updates of addresses requires a scalable, reliable, and observable approach. Providing bulk endpoints or batch jobs lets you submit or schedule many updates in one go, rather than issuing individual requests one by one. Processing in chunks keeps resource usage predictable and reduces the risk of timeouts, while making it easier to resume after partial failures. Designing the operations to be idempotent ensures that retries won’t create duplicates or inconsistent state, which is crucial when network hiccups or partial errors occur. Reporting results per record gives clear visibility into which updates succeeded or failed, aiding auditing and targeted remediation. When these aspects are combined, you get a complete and robust solution for bulk address updates, which is why this approach is the best.
