    GCP PCA · Question 32 · Technical Processes

    Your company has a hybrid cloud architecture. You have internal applications running on-premises and on GCP. You want on-premises servers to be able to resolve the DNS names of GCP Compute Engine instances (e.g., myserver.c.myproject.internal). How should you configure Cloud DNS?

    Answer options:

    A.

    Create an outbound server policy in Cloud DNS to forward queries to the on-premises DNS servers.

    B.

    Create an inbound server policy in Cloud DNS and configure your on-premises DNS servers to forward queries for GCP domains to the inbound forwarder IP addresses.

    C.

    Create a public Cloud DNS zone and replicate the internal IP addresses to it.

    D.

    Configure Cloud NAT to translate DNS requests from on-premises to GCP.

    How to approach this question

    Determine the direction of the DNS query: On-prem -> GCP requires an Inbound policy.

    Full Answer

    B.Create an inbound server policy in Cloud DNS and configure your on-premises DNS servers to forward queries for GCP domains to the inbound forwarder IP addresses.✓ Correct
    Create an inbound server policy in Cloud DNS and configure your on-premises DNS servers to forward queries for GCP domains to the inbound forwarder IP addresses.
    To allow on-premises systems to resolve GCP internal DNS names, you use Cloud DNS Inbound Forwarding. This creates an inbound server policy that provisions IP addresses in your VPC. You then configure your on-premises DNS resolver to forward queries for GCP domains (like `.internal`) to these IP addresses via your Cloud VPN or Cloud Interconnect.

    Common mistakes

    Confusing Inbound and Outbound DNS policies. Inbound = On-prem resolving GCP. Outbound = GCP resolving On-prem.
