PCNE Practice Question: Designing, Planning, and Prototyping a GCP Network
A company has multiple projects that each need their own administrative control but must share a common VPC network. Which networking solution should they use?
⚠ Common exam trap
Candidates often confuse VPC peering (Option D) with Shared VPC, not realizing that peering does not allow a single common VPC network and lacks centralized administrative control, while Shared VPC is designed exactly for this use case.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Shared VPC with the host project and attach service projects.
Shared VPC allows an organization to connect resources from multiple projects to a common VPC network, enabling centralized control of the network while maintaining administrative isolation for each project. The host project owns the VPC and firewall rules, and service projects can use subnets within that VPC, meeting the requirement for separate administrative control with a shared network.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a single VPC in one project and grant all users access to that project.
Why it's wrong here
Compromises administrative boundaries and security.
- ✗
Create separate VPCs for each project and connect via Cloud VPN.
Why it's wrong here
Adds VPN complexity and latency.
- ✓
Use Shared VPC with the host project and attach service projects.
Why this is correct
Provides centralized network management with per-project resource control.
- ✗
Create a VPC in each project and peer them all together.
Why it's wrong here
Requires full-mesh peering, increasing complexity and overhead.
