Google Cloud Professional Cloud Network Engineer — Question 98

You have just deployed your infrastructure on Google Cloud. You now need to configure the DNS to meet the following requirements:

• Your on-premises resources should resolve your Google Cloud zones.
• Your Google Cloud resources should resolve your on-premises zones.
• You need the ability to resolve “.internal” zones provisioned by Google Cloud.

What should you do?

Answer options

• 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.

Correct answer: B

Explanation

Option B is correct because it allows for bi-directional DNS resolution, ensuring both on-premises and Google Cloud resources can resolve each other's zones effectively. Options A and C only allow outbound resolution without inbound capabilities for Google Cloud zones, while option D does not provide the necessary configuration for resolving both environments' zones appropriately.
