    Hello hunny,

    Thank you for sharing your thoughts on this item.

    The key issue in this scenario is the retrieval cost model. Since the workload scans through 200 TB every month, S3 Glacier Instant Retrieval’s per‑GB retrieval charges would add up significantly. Intelligent‑Tiering avoids those retrieval costs and integrates seamlessly with FSx for Lustre, which is designed for high‑performance workloads like financial modeling.

    That’s why the exam answer favors Intelligent‑Tiering + FSx for Lustre. It balances cost savings with HPC‑level performance, whereas GIR is better suited for archival data that is accessed occasionally, not for full dataset scans.

    I hope this helps! Let me know if you need further assistance.

    Best regards,
    JR @ Tutorials Dojo
