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.
