GCP ACE · Question 11 · Domain 2.1: Planning and estimating GCP product use
Your company is planning to migrate a legacy application to Google Cloud. The application requires 4 vCPUs and 16 GB of RAM. It must run 24/7 for the next 3 years without interruption. You need to estimate the MOST cost-effective Compute Engine configuration using the Pricing Calculator.
Which option should you select in the calculator to minimize costs?

Which option should you select in the calculator to minimize costs?
Answer options:
A.
An e2-standard-4 instance with Sustained Use Discounts.
B.
A custom machine type (4 vCPU, 16 GB RAM) with a 3-year Committed Use Discount.
C.
An e2-standard-4 preemptible instance.
D.
A Spot VM instance.
How to approach this question
Match the 24/7, 3-year requirement with the appropriate discount model.
Full Answer
B.A custom machine type (4 vCPU, 16 GB RAM) with a 3-year Committed Use Discount.✓ Correct
A custom machine type (4 vCPU, 16 GB RAM) with a 3-year Committed Use Discount.
For predictable workloads that will run 24/7 for an extended period (1 or 3 years), Committed Use Discounts (CUDs) provide the deepest discounts. Preemptible/Spot VMs are cheaper but do not meet the 'without interruption' requirement.
Common mistakes
Selecting Preemptible/Spot VMs purely based on price, ignoring the availability requirement.
