The correct statements about Shared VPC include that the host project must be in the same organization as the service projects. This requirement exists because Shared VPC relies on organization-level IAM policies to delegate subnet usage across projects, ensuring centralized control and security boundaries within a single Google Cloud organization. On the Google Professional Cloud Network Engineer exam, this concept tests your understanding of Shared VPC administration, specifically how host and service projects interact under organization policies. A common trap is assuming projects from different organizations can share a VPC, but Shared VPC strictly requires same-org membership; cross-org connectivity would need VPC peering or VPN instead. Remember that the Shared VPC admin role is assigned at the organization level to manage subnet sharing, while service project admins only consume resources. For a quick memory tip: think of Shared VPC as a family—everyone (service projects) must live in the same house (organization) to share the backyard (subnets).
PCNE Implementing a Virtual Private Cloud Practice Question
This PCNE practice question tests your understanding of implementing a virtual private cloud. 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.
Which THREE statements about Shared VPC are correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Shared VPC admin role can be assigned to manage the host VPC network.
Shared VPC allows service projects to use host VPC subnets, requires same organization, and can be managed via Shared VPC admin role.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The Shared VPC admin role can be assigned to manage the host VPC network.
Why this is correct
The compute.xpnAdmin role allows management of Shared VPC.
Service projects can delete subnets in the host VPC.
Why it's wrong here
Service projects do not have permission to modify host VPC resources by default.
✗
Service projects can create their own VPCs that peer with the host VPC.
Why it's wrong here
Service projects use the host VPC directly; they do not create separate peering.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
CIDR notation defines the prefix length.
Block size helps identify subnet boundaries.
Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
The required host count determines the smallest suitable subnet.
TExam Day Tips
→Write the block size before choosing the subnet.
→Check whether the question asks for hosts, subnets or a specific address range.
→Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
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.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related PCNE subnetting questions on CIDR, address ranges, and subnet selection.
