Google Cloud Professional Cloud Security Engineer — Question 40

A customer is collaborating with another company to build an application on Compute Engine. The customer is building the application tier in their GCP
Organization, and the other company is building the storage tier in a different GCP Organization. This is a 3-tier web application. Communication between portions of the application must not traverse the public internet by any means.
Which connectivity option should be implemented?

Answer options

• A. VPC peering
• B. Cloud VPN
• C. Cloud Interconnect
• D. Shared VPC

Correct answer: A

Explanation

VPC peering is the best option for connecting two different GCP Organizations without exposing traffic to the public internet, allowing private communication between the application and storage tiers. Cloud VPN and Cloud Interconnect are more suited for connecting on-premises networks to GCP, while Shared VPC is designed for managing resources within the same organization rather than between different organizations.
