Google Professional Cloud Network Engineer Question 550
Select 3Google Cloud PlatformYour organization is migrating workloads to Google Cloud while retaining an on-premises DNS setup for internal domains. You need to ensure that instances in Google Cloud can resolve on-premises domain names and on-premises systems can resolve Google Cloud internal domain names. Which of the following steps should you take to properly integrate on-premises DNS with Google Cloud DNS?
- A
Set up a Cloud DNS inbound server policy for the Google Cloud project and configure forwarding rules to direct traffic for the on-premises domains to your on-premises DNS servers.
- B
Create a Cloud VPN or Cloud Interconnect connection between your on-premises environment and Google Cloud.
- C
Use Cloud DNS outbound server policy to forward queries for Google Cloud internal domain names to the on-premises DNS servers.
- D
Configure a Cloud DNS peering zone to enable DNS resolution between on-premises and Google Cloud.
- E
Set up a private DNS zone in Cloud DNS and manually replicate on-premises DNS records.
Show answer and explanation
Correct answers: A, B, D
Explanation
To integrate on-premises DNS with Google Cloud, you need to ensure bidirectional DNS resolution. Setting up a Cloud DNS inbound server policy with forwarding rules ensures that Google Cloud can resolve on-premises domain names. Establishing a Cloud VPN or Cloud Interconnect connection provides the network connectivity required for DNS resolution. Configuring a Cloud DNS peering zone allows DNS resolution between on-premises and Google Cloud without requiring manual replication of DNS records, making it a scalable and efficient solution.
- A. Correct.
Correct: Setting up a Cloud DNS inbound server policy with forwarding rules allows Google Cloud to resolve on-premises domain names by forwarding queries to on-premises DNS servers.
- B. Correct.
Correct: A Cloud VPN or Cloud Interconnect connection is required to establish network connectivity between Google Cloud and on-premises environments, which is essential for DNS integration.
- C. Incorrect.
Incorrect: Cloud DNS outbound server policies are not used for forwarding Google Cloud internal domain queries to on-premises DNS servers. Instead, they are used to resolve external queries from Google Cloud to on-premises DNS.
- D. Correct.
Correct: A Cloud DNS peering zone enables DNS resolution between on-premises and Google Cloud by linking the DNS namespaces of both environments.
- E. Incorrect.
Incorrect: While creating a private DNS zone and replicating DNS records could work, it is not a scalable or recommended approach for integrating on-premises DNS with Google Cloud.
