This PCA practice question tests your understanding of manage implementation of cloud architecture. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization is implementing a Hub-and-Spoke network topology with multiple VPCs. Which Google Cloud product is designed for centralized connectivity and policy enforcement?
Cloud VPN
Why wrong: For connecting on-prem networks to GCP.
Cloud NAT
Why wrong: For outbound internet access.
Network Connectivity Center
Why wrong: For hybrid connectivity across on-prem and cloud.
Shared VPC
Centralized VPC management with policy enforcement.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Shared VPC
Shared VPC (D) is the correct answer because it allows an organization to centrally manage connectivity and enforce network policies across multiple VPCs from a single host project. By designating a host project and attaching service projects, Shared VPC enables centralized control over firewall rules, routes, and IAM policies, which is essential for a hub-and-spoke topology where the host VPC acts as the hub and service VPCs as spokes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse Network Connectivity Center (NCC) as a centralized hub for VPCs, but NCC is designed for hybrid connectivity (on-prem to cloud) and multi-cloud, not for managing multiple VPCs within a single Google Cloud organization with centralized policy enforcement, which is the domain of Shared VPC.
Detailed technical explanation
Shared VPC uses a host project that contains the VPC network, subnets, and firewall rules, while service projects can use those subnets via IAM permissions. Under the hood, Shared VPC leverages Google's Andromeda SDN to enforce consistent routing and security policies across all attached projects, ensuring that traffic between service projects in the same Shared VPC flows through the host VPC's routing infrastructure. A real-world scenario is a large enterprise with separate teams (e.g., dev, prod, finance) each in their own service project, but all sharing a common host VPC for centralized egress, ingress, and security controls.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
