- A
Create a new VPC in Google Cloud, then establish a VPN connection between on-premises and the new VPC, then configure BGP for dynamic routing, then set up VPC peering (if needed), and finally migrate workloads to the new VPC.
This is the correct order because a VPC must exist before you can terminate a VPN on it. After VPN connectivity, BGP enables dynamic routing. VPC peering connects to other VPCs, and workloads are migrated last.
- B
Establish a VPN connection first, then configure BGP, then create a new VPC, then set up VPC peering, then migrate workloads.
Why wrong: This is incorrect because the VPN connection requires an existing VPC to terminate; creating the VPC after VPN is not possible.
- C
Configure BGP first, then create a new VPC, then establish VPN, then set up VPC peering, then migrate workloads.
Why wrong: This is incorrect because BGP routing requires network connectivity (such as VPN) to be in place first; otherwise BGP sessions cannot be established.
- D
Create a new VPC, then set up VPC peering, then establish VPN, then configure BGP, then migrate workloads.
Why wrong: This is incorrect because VPC peering is typically used to connect VPCs after network connectivity is established; peering before VPN and BGP is out of order and may not be functional.
On-Premises to Google Cloud Migration Using VPN and VPC Peering
This PCNE practice question tests your understanding of implementing network security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 migrate an on-premises network to Google Cloud using a VPN and VPC peering into the correct order.

Correct answer & explanation
Create a new VPC in Google Cloud, then establish a VPN connection between on-premises and the new VPC, then configure BGP for dynamic routing, then set up VPC peering (if needed), and finally migrate workloads to the new VPC.
In a typical migration using VPN and VPC peering, you first create a VPC in Google Cloud as the target environment. Then, you set up a VPN connection between the on-premises network and this new VPC. After establishing VPN connectivity, configure BGP for dynamic routing to exchange routes. If needed, set up VPC peering to connect the new VPC to other VPCs in Google Cloud. Finally, migrate workloads from on-premises to the new VPC. The given common mistake sequence (VPN, BGP, new VPC) is incorrect because a VPC must exist before VPN can be created.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Create a new VPC in Google Cloud, then establish a VPN connection between on-premises and the new VPC, then configure BGP for dynamic routing, then set up VPC peering (if needed), and finally migrate workloads to the new VPC.
Why this is correct
This is the correct order because a VPC must exist before you can terminate a VPN on it. After VPN connectivity, BGP enables dynamic routing. VPC peering connects to other VPCs, and workloads are migrated last.

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.
