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 (or Preemptible VMs) Compute Engine custom machine types
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.
