GCP ACE · Question 13 · Domain 2.2: Planning and configuring compute resources

You have a batch processing workload that takes 2 hours to complete. The workload is fault-tolerant and can be interrupted and resumed without issues. You want to minimize compute costs. Which TWO configurations should you consider? (Select TWO)

Answer options:

A.

Spot VMs (or Preemptible VMs)

B.

Committed Use Discounts

C.

Compute Engine custom machine types

D.

Sole-tenant nodes

E.

Shielded VMs

How to approach this question

Look for cost-saving features specifically suited for interruptible workloads and precise resource allocation.

Full Answer

Spot VMs (formerly Preemptible VMs) are highly affordable compute instances suitable for batch jobs and fault-tolerant workloads, as Compute Engine might stop them if it needs the capacity. Custom machine types allow you to tailor the vCPU and memory to your exact needs, preventing over-provisioning and saving money.

Common mistakes

Selecting Committed Use Discounts, which are for steady-state, long-term workloads.
