    • $2M budget

    QUESTION: To meet the CFO's requirement of reducing costs by 40%, which pricing strategy should you apply to the baseline, predictable compute workloads?

    Answer options:

    A.

    Rely on Sustained Use Discounts (SUDs) for all workloads.

    B.

    Use Spot VMs for all gaming servers.

    C.

    Purchase 3-year Committed Use Discounts (CUDs).

    D.

    Implement custom machine types to exactly match on-premises specifications.

    How to approach this question

    Identify the GCP billing mechanism that provides the deepest discount for predictable, long-term workloads.

    Full Answer

    C.Purchase 3-year Committed Use Discounts (CUDs).✓ Correct
    Committed Use Discounts (CUDs) provide deeply discounted prices in exchange for a 1- or 3-year commitment. For a baseline workload that will run 24/7, a 3-year CUD is the most effective way to drastically reduce compute costs and satisfy the CFO.

    Common mistakes

    Selecting Spot VMs (B) to save money, ignoring the critical business requirement of 99.95% uptime.
