Answer: Configure both an inbound server policy and outbound DNS forwarding zones with the target as the on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google Cloud's DNS resolver.
The requirements involve bidirectional DNS resolution between Google Cloud and on-premises resources, including resolving Google's .internal zones. To achieve this: 1. **Inbound Server Policy**: Allows on-premises DNS resolvers to query Cloud DNS, enabling on-premises resources to resolve Google Cloud zones (including .internal). 2. **Outbound DNS Forwarding Zones**: Configures Cloud DNS to forward queries for on-premises zones to the on-premises DNS resolver, enabling Google Cloud resources to resolve on-premises zones. 3. **On-premises Configuration**: The on-premises DNS resolver must forward Google Cloud zone queries to Cloud DNS's resolver (e.g., via the inbound policy), ensuring proper resolution of private .internal zones. Option B correctly implements both inbound and outbound policies, ensuring bidirectional resolution. Other options either use public DNS (incorrect for .internal zones) or lack necessary policies.

You have deployed infrastructure on Google Cloud and need to configure DNS to meet these requirements:
• On-premises resources must resolve Google Cloud DNS zones.
• Google Cloud resources must resolve on-premises DNS zones.
• The solution must support resolving ".internal" zones provisioned by Google Cloud.
What is the correct configuration approach?
A
Configure an outbound server policy, and set your alternative name server to be your on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google's public DNS 8.8.8.8.
B
Configure both an inbound server policy and outbound DNS forwarding zones with the target as the on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google Cloud's DNS resolver.
C
Configure an outbound DNS server policy, and set your alternative name server to be your on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google Cloud's DNS resolver.
D
Configure Cloud DNS to DNS peer with your on-premises DNS resolver. Configure your on-premises DNS resolver to forward Google Cloud zone queries to Google's public DNS 8.8.8.8.
