Subtask 1.3: Network, Storage, ComputeNetworkingShared VPCEnterprise Architecture

GCP PCA · Question 23 · Network, Storage, Compute

An enterprise has a central IT team and multiple independent development teams. The central IT team must control all network resources (subnets, firewalls, VPNs), while the development teams need full control over creating VMs and GKE clusters in their own projects. How should you design the GCP network architecture?

Answer options:

A.

Create a separate VPC in each development team's project and connect them using VPC Peering.

B.

Create a Shared VPC in a Host Project managed by central IT, and attach the development teams' projects as Service Projects.

C.

Place all resources (network and compute) in a single project and use IAM conditions to restrict access.

D.

Use Cloud VPN to connect the development projects to a central IT project.

How to approach this question

Identify the GCP feature that separates network administration from compute administration across multiple projects.

Full Answer

B.Create a Shared VPC in a Host Project managed by central IT, and attach the development teams' projects as Service Projects.✓ Correct
Shared VPC is the exact solution for this organizational structure. It designates one project as a 'Host Project' where the VPC, subnets, and firewalls reside (managed by Network Admins). Other projects are attached as 'Service Projects'. Developers in Service Projects can create VMs that use the subnets from the Host Project, ensuring centralized network security.

Common mistakes

Selecting VPC Peering, which connects decentralized networks rather than centralizing network administration.
