GCP cloud developer free practice test.

This practice test covers all the required topics as per the exam guide.

Welcome to your gcpclouddeveloper

Q1.You are a cloud developer helping an enterprise customer deploy their application on Google Compute Engine. The customer's IT team already created two projects, for marketing and sales departments, within the US-Central1 region. The network topology, firewall rules, and routes are identical for the marketing and sales projects. The IT manager wants your help in designing a single network that will be shared by applications running within the sales and marketing projects. Which statement regarding your VPC network(s) that will contain the marketing and sales resources is correct, and can help your IT manager design the best solution?

A.All VPC networks are global resources, so every VPC and its subnets can be shared between the marketing and sales projects running in the same region.

B.Although VPCs are global resources, sales and marketing need to use a shared VPC to access the same resources in specific subnets.

C.VPCs cannot be used by different projects, so sales and marketing must design separate networks within separate VPCs.
