PCNE Implementing a Virtual Private Cloud Practice Question
A company is designing a VPC for a production environment that must meet the following requirements: support multiple projects, centralized network administration, and allow each project to have its own firewall rules. Which THREE components should be used?
⚠ Common exam trap
Google Cloud often tests the distinction between connectivity solutions (Cloud VPN, VPC peering) and network administration models (Shared VPC), leading candidates to mistakenly choose VPC peering for multi-project setups when Shared VPC is required for centralized control with per-project firewall rules.
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
✓
Service projects
A is correct because service projects in a Shared VPC architecture allow each project to host its own resources (e.g., Compute Engine instances) while maintaining separate firewall rules and security policies. This enables centralized network administration via the host project while giving each project autonomy over its own firewall configurations, meeting the requirement for multiple projects with independent firewall rules.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Service projects
Why this is correct
Service projects consume Shared VPC networks.
- ✓
Host project
Why this is correct
The host project contains the Shared VPC network.
- ✗
Cloud VPN
Why it's wrong here
Cloud VPN is for connecting on-premises, not for multi-project VPC.
- ✗
VPC peering
Why it's wrong here
VPC peering is not needed when using Shared VPC.
- ✓
Shared VPC
Why this is correct
Shared VPC enables centralized network management across projects.
