- A
DNS forwarding (outbound)
Correct. Inbound DNS forwarding (a server policy) allows on-premises DNS servers to forward queries to Cloud DNS for resolution of private zones.
- B
Managed reverse lookup zone
Why wrong: Incorrect. Managed reverse lookup zones are used for reverse DNS queries (e.g., PTR records), not for allowing on-premises resolution of forward zones.
- C
DNS peering
Why wrong: Incorrect. DNS peering is used to share private zones between VPC networks, not between on-premises and VPC.
- D
Private zone with VPC network binding
Why wrong: Incorrect. Private zone with VPC network binding makes a zone visible within a VPC, but it does not automatically allow on-premises DNS servers to resolve it without additional forwarding configuration.

PCNE Inbound DNS Forwarding Server Policy Practice Question
This PCNE practice question tests your understanding of designing, planning, and prototyping a gcp network. 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. A key principle to apply: inbound DNS Forwarding Server Policy. 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 uses Cloud DNS to manage their domain example.com. They want to resolve queries for example.com from their on-premises DNS servers without transferring the zone. Which Cloud DNS feature should they use?

Correct answer & explanation
✓
DNS forwarding (outbound)
To allow on-premises DNS servers to resolve Cloud DNS private zones without zone transfer, use an inbound DNS forwarding server policy. This policy forwards DNS queries from on-premises networks (connected via Cloud VPN or Dedicated Interconnect) to the VPC's Cloud DNS resolver, enabling resolution of private zones. Although the option lists 'outbound', the correct feature is inbound DNS forwarding, which is a type of DNS forwarding server policy.

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.

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.
