ACE Practice Question: Two GCP projects, A and B, have VPC peering…
This ACE practice question tests your understanding of two gcp projects, a and b, have vpc peering…. 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.
Two GCP projects, A and B, have VPC peering configured. Project A is peered with B, and Project B is peered with Project C. Can VMs in Project A reach VMs in Project C through Project B?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Yes — if Project B has IP forwarding enabled, it acts as a router between A and C
IP forwarding on VMs allows packet forwarding within a VPC — it doesn't override VPC peering's non-transitive networking model.
B
Distractor review
It depends on the firewall rules in Project B's VPC
Firewall rules control which traffic is allowed — the peering topology's non-transitive nature is a routing constraint, not a firewall issue.
C
Distractor review
Yes — VPC peering automatically enables transitive routing through intermediate peered networks
GCP VPC peering is explicitly non-transitive. Traffic cannot flow A → B → C through peering — A and C must be directly peered.
D
Best answer
No — VPC peering is non-transitive; A and C must be directly peered to communicate
VPC peering in GCP does not support transitive routing. Project A's peering with B gives A access to B's VPC only — not to networks B is peered with (like C).
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

FAQ
Questions learners often ask
What does this ACE question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: No — VPC peering is non-transitive; A and C must be directly peered to communicate — VPC peering is non-transitive in GCP. Traffic from Project A can reach Project B (directly peered), but Project B does not forward traffic between Project A and Project C. Transitive routing across peering connections is not supported — A and C must be directly peered if they need to communicate.
What should I do if I get this ACE question wrong?
Identify which ACE exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
