- A
Set up DNS peering between the zones.
Why wrong: DNS peering is for cross-project resolution, not split-horizon.
- B
Configure the private zone with a VPC network binding.
Why wrong: This is part of private zone creation, but the question asks for two steps; creating the public and private zones are the key steps.
- C
Use DNS forwarding to on-premises servers.
Why wrong: Forwarding is for hybrid environments, not split-horizon within GCP.
- D
Create a public managed zone for the domain.
Handles external queries.
- E
Create a private managed zone for the domain.
Handles internal queries.

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 developer wants to configure Cloud DNS for split-horizon DNS where internal queries resolve to private IPs and external queries resolve to public IPs. Which TWO steps should they take?

Correct answer & explanation
✓
Create a public managed zone for the domain.
Split-horizon DNS is achieved by having a private zone for internal resolution and a public zone for external resolution, both authoritative for the same domain.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
