- A
Enable 'export custom routes' on Production VPC and 'import custom routes' on Development VPC.
Why wrong: That would export Production's routes, not import Development's.
- B
Enable 'export custom routes' on Development VPC and 'import custom routes' on Production VPC.
This allows Development to export its custom routes and Production to import them.
- C
Enable 'import custom routes' on both VPCs.
Why wrong: Import alone does not help without export.
- D
Enable 'export custom routes' on both VPCs.
Why wrong: Both need to export and import; exporting alone does not import.

PCNE Practice Question: Designing, Planning, and Prototyping a GCP Network
This PCNE practice question tests your understanding of designing, planning, and prototyping a gcp network. 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.
A company has two VPCs (Production and Development) that are peered. The Development VPC has a custom route to an on-premises network via a VPN tunnel. They want the Production VPC to automatically learn this route. What must be configured on the VPC peering?
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
✓
Enable 'export custom routes' on Development VPC and 'import custom routes' on Production VPC.
To allow exchange of custom routes between peered VPCs, both VPCs must enable 'export custom routes' and 'import custom routes' on the peering connection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
