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 a new data processing workload. The workload will run on Compute Engine and process data stored in Cloud Storage.

Which TWO factors will significantly impact your estimated monthly cost? (Select TWO)

Answer options:

A.

The region where the Compute Engine instances and Cloud Storage buckets are deployed.

B.

The amount of network ingress traffic (data transferred into Google Cloud).

C.

The amount of network egress traffic (data transferred out of Google Cloud).

D.

The specific IAM roles assigned to the service accounts running the workload.

E.

The number of VPC networks created in the project.

How to approach this question

Consider what GCP charges for. Location matters, and data leaving the network matters. Data entering the network and IAM are free.

Full Answer

The region where the resources are deployed, and the amount of network egress traffic.
When estimating costs in Google Cloud, the region is a major factor because prices for compute, storage, and other services vary by location due to local infrastructure costs. Additionally, network egress (data leaving Google Cloud or moving between regions) is a billable metric that can significantly impact costs. Network ingress (data coming in) is free, and logical constructs like IAM roles or empty VPCs do not incur charges.

Common mistakes

Assuming network ingress is billed, or forgetting that prices vary by region.
