Google Professional Cloud Network Engineer Question 165
Single answerGoogle Cloud PlatformYour company has a multi-cloud setup and wants to allow DNS resolution between services hosted on Google Cloud and another cloud provider. The services in Google Cloud are hosted in a VPC named 'prod-vpc', and the other cloud’s DNS server is reachable via a VPN connection. You need to design a DNS resolution strategy that ensures queries for the other cloud's DNS zone are forwarded correctly while minimizing latency. What should you do?
- A
Create a Cloud DNS forwarding zone in 'prod-vpc' and configure it with the IP address of the other cloud's DNS server.
- B
Set up a private DNS zone in 'prod-vpc' and manually replicate the DNS records from the other cloud.
- C
Enable DNS peering between 'prod-vpc' and the other cloud's VPC to forward queries automatically.
- D
Deploy a Cloud DNS outbound server in 'prod-vpc' and configure it to forward queries to the other cloud's DNS server.
Show answer and explanation
Correct answer: A
Explanation
A Cloud DNS forwarding zone is the ideal solution for forwarding DNS queries to an external DNS server, such as the one hosted in another cloud provider. It allows for efficient and dynamic DNS resolution without requiring manual replication or additional infrastructure. This approach minimizes latency and simplifies management.
- A. Correct.
Correct. A Cloud DNS forwarding zone allows you to forward DNS queries for specific domains to an external DNS server, in this case, the other cloud's DNS server, ensuring seamless resolution.
- B. Incorrect.
Incorrect. Setting up a private DNS zone and manually replicating records is error-prone, requires constant updates, and does not scale well for dynamic environments.
- C. Incorrect.
Incorrect. DNS peering is not a supported feature across different cloud providers. It is primarily designed for peering between Google Cloud VPCs.
- D. Incorrect.
Incorrect. Deploying a Cloud DNS outbound server is unnecessary in this scenario, as the Cloud DNS forwarding zone already provides a direct way to forward queries.
