Network topologies — GCP PCA Practice Question 24

How to approach this question

Understand the two-way nature of hybrid DNS: inbound policies for on-prem->GCP, and forwarding zones for GCP->on-prem.

Full Answer

A.Create an inbound server policy in Cloud DNS, and create a private forwarding zone pointing to the on-premises DNS servers.✓ Correct

Hybrid DNS requires two components. 1) Inbound server policy: Creates an IP in your VPC that on-prem DNS servers can query to resolve GCP names. 2) Forwarding zone: Tells Cloud DNS that any query for `corp.local` from a GCP VM should be forwarded over the Interconnect/VPN to the on-prem DNS servers.

Common mistakes

Only configuring one side of the connection, or trying to override the default GCP metadata DNS server on the VMs.

You are designing a hybrid DNS architecture. On-premises servers need to resolve internal GCP hostnames (e.g., `my-db.us-central1.c.my-project.internal`), and GCP VMs need to resolve on-premises hostnames (e.g., `app.corp.local`). How should you configure Cloud DNS?
