- A
1. Verify that the VPC networks have non-overlapping IP ranges. 2. Create a VPC peering connection from Project A to Project B. 3. Create a VPC peering connection from Project B to Project A. 4. Verify the peering status and network connectivity.
This order ensures prerequisites are met (non-overlapping IPs), then establishes both directions of peering, which is required for bidirectional communication. Finally, verification confirms success.
- B
1. Verify that the VPC networks have non-overlapping IP ranges. 2. Create a VPC peering connection from Project A to Project B. 3. Verify the peering status and network connectivity. (No peering from Project B to Project A)
Why wrong: This order creates only one side of the peering. VPC peering requires both sides to be set up; otherwise, traffic flows only in one direction or not at all.
- C
1. Create a VPC peering connection from Project A to Project B. 2. Create a VPC peering connection from Project B to Project A. 3. Verify that the VPC networks have non-overlapping IP ranges. 4. Verify the peering status and network connectivity.
Why wrong: Checking IP range overlap is done after peering attempts. If IPs overlap, peering will fail, so this order wastes effort and causes potential errors early.
- D
1. Create a VPC peering connection from Project B to Project A. 2. Create a VPC peering connection from Project A to Project B. 3. Verify that the VPC networks have non-overlapping IP ranges. 4. Verify the peering status and network connectivity.
Why wrong: Similar to C but reverses the order of peering creation. However, the critical flaw is still performing IP range check after creating peering, which can lead to immediate failure.
Google PCA Design and plan a cloud solution architecture Practice Question
This PCA practice question tests your understanding of design and plan a cloud solution 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.
Drag and drop the steps to set up a VPC network peering between two projects in Google Cloud into the correct order.
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
1. Verify that the VPC networks have non-overlapping IP ranges. 2. Create a VPC peering connection from Project A to Project B. 3. Create a VPC peering connection from Project B to Project A. 4. Verify the peering status and network connectivity.
VPC peering requires bidirectional connections; both sides must initiate peering. IP ranges must not overlap.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown

1. Verify that the VPC networks have non-overlapping IP ranges. 2. Create a VPC peering connection from Project A to Project B. 3. Create a VPC peering connection from Project B to Project A. 4. Verify the peering status and network connectivity.
Why this is correct
This order ensures prerequisites are met (non-overlapping IPs), then establishes both directions of peering, which is required for bidirectional communication. Finally, verification confirms success.

Why it's wrong here
Similar to C but reverses the order of peering creation. However, the critical flaw is still performing IP range check after creating peering, which can lead to immediate failure.
Common exam traps
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.

Detailed technical explanation
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.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
