Question 8

A company runs a batch processing workload every night that takes 60 minutes on a single n1-standard-32 VM. They want to reduce costs by using preemptible VMs but need the job to complete within 90 minutes. The job can be parallelized if necessary. Which approach is most cost-effective?

Accepted Answer

Split the workload across 4 preemptible n1-standard-8 VMs with checkpointing.. Preemptible VMs can be terminated at any time, so running multiple smaller instances with checkpointing and retries reduces cost and meets the deadline.

Answer

Use a single non-preemptible VM to ensure completion.

Answer

Use the same VM but as preemptible; if preempted, restart the job from scratch.

Answer

Use a single preemptible VM with persistent disk snapshots every 10 minutes.
