GCP ACE · Question 10 · Domain 2.1: Planning and estimating GCP product use

You are using the Google Cloud Pricing Calculator to estimate the monthly cost of running a new web application on Compute Engine.

Which of the following factors does NOT affect the estimated cost of a Compute Engine instance?

Answer options:

A.

The selected Google Cloud region

B.

The operating system (OS) image

C.

Ingress network traffic

D.

Egress network traffic

How to approach this question

Recall the general rule for cloud networking costs: data coming in is usually free, data going out costs money.

Full Answer

C.Ingress network traffic✓ Correct
Ingress network traffic
In Google Cloud (and most major cloud providers), ingress network traffic (data entering the GCP network) is free. Therefore, it does not factor into the cost estimate. Region, OS licensing, and egress traffic all incur costs.

Common mistakes

Assuming all network traffic (both ingress and egress) is billed equally.
