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?

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

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.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Set up DNS peering between the zones.

    Why it's wrong here

    DNS peering is for cross-project resolution, not split-horizon.

  • Configure the private zone with a VPC network binding.

    Why it's wrong here

    This is part of private zone creation, but the question asks for two steps; creating the public and private zones are the key steps.

  • Use DNS forwarding to on-premises servers.

    Why it's wrong here

    Forwarding is for hybrid environments, not split-horizon within GCP.

  • Create a public managed zone for the domain.

    Why this is correct

    Handles external queries.

  • Create a private managed zone for the domain.

    Why this is correct

    Handles internal queries.
