Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✗

    Reserved instances

    Why it's wrong here

    Reserved instances require a 1- or 3-year commitment, not suitable for a daily job.

  • ✓

    Spot (preemptible) instances

    Why this is correct

    Spot instances provide the lowest cost for fault-tolerant, short-lived workloads.

  • ✗

    Dedicated hosts

    Why it's wrong here

    Dedicated hosts are costly and provide physical isolation, unnecessary for this job.

  • ✗

    On-demand instances

    Why it's wrong here

    On-demand is more expensive and not cost-optimized for short, interruptible jobs.
