GCP ACE · Question 11 · Domain 2.1: Planning and estimating GCP product use

You are using the Google Cloud Pricing Calculator to estimate the cost of running a fleet of Compute Engine instances. You want to ensure your estimate is as accurate as possible.

Which TWO factors will significantly impact the estimated cost of a Compute Engine instance? (Select TWO)

Answer options:

A.

The geographic region where the instance is deployed.

B.

The specific zone within a region (e.g., us-central1-a vs us-central1-b).

C.

Whether the instance is a Spot VM (Preemptible).

D.

The IAM roles assigned to the service account attached to the instance.

E.

The VPC network name the instance is attached to.

How to approach this question

Consider what physical and billing attributes affect GCP pricing models.

Full Answer

The geographic region where the instance is deployed., Whether the instance is a Spot VM (Preemptible).
Compute Engine costs are heavily influenced by the region (due to varying infrastructure costs globally) and the provisioning model (Spot/Preemptible VMs are heavily discounted because Google can reclaim them). Zones within a region cost the same.

Common mistakes

Thinking that zones within the same region have different prices.
