A company is integrating their on-premises data center with a Google Cloud Virtual Private Cloud (VPC) network via Cloud Interconnect. Internal application servers hosted in the VPC reside within a Cloud DNS private zone named internal.example.com. On-premises client machines need to resolve hostnames within this private DNS zone over the hybrid connection. Which Cloud DNS configuration should be planned to satisfy this requirement?
- Configure a Cloud DNS inbound DNS forwarding policy on the VPC network to allow on-premises systems to query Cloud DNS entry points.Answer
- BConfigure a Cloud DNS outbound DNS forwarding zone targeting the on-premises DNS server IP addresses.
- CCreate an External HTTP(S) Load Balancer with Cloud CDN enabled to cache DNS resolution requests at Google edge locations.
- DPromote the Cloud DNS private zone to a public managed zone and allow public internet recursion.
Answer
Configure a Cloud DNS inbound DNS forwarding policy on the VPC network to allow on-premises systems to query Cloud DNS entry points.
Inbound DNS forwarding allows networks connected to a VPC (such as on-premises networks via Cloud Interconnect or VPN) to send DNS queries to Cloud DNS entry point IP addresses inside the VPC, resolving records in private zones.
