Google Professional Cloud Network Engineer Question 532
Select 3Google Cloud PlatformYour company is migrating its application to Google Cloud and requires the creation of a DNS zone to manage DNS records for the application. The application must be accessible via 'app.example.com', and redundancy is required for the name servers. Which steps should you perform to achieve this?
- A
Create a public Cloud DNS zone for the domain 'example.com' and add DNS records for 'app.example.com'.
- B
Create a private Cloud DNS zone for 'example.com' and configure DNS records for 'app.example.com'.
- C
Update the registrar's name server configuration to use the name servers provided by the Cloud DNS zone.
- D
Manually set up a failover mechanism for Cloud DNS name servers.
- E
Verify the DNS record resolution using tools like 'dig' or 'nslookup'.
Show answer and explanation
Correct answers: A, C, E
Explanation
To manage a publicly accessible domain like 'example.com', you need to create a public Cloud DNS zone, configure the desired DNS records (e.g., 'app.example.com'), and update the domain registrar's name servers to use the ones provided by Cloud DNS. Verifying the DNS resolution ensures that the configuration is correct. Private zones and manual failover mechanisms are not applicable in this scenario.
- A. Correct.
Correct: A public Cloud DNS zone is required to manage the DNS records for a publicly accessible domain like 'app.example.com'.
- B. Incorrect.
Incorrect: A private Cloud DNS zone is only used for internal DNS resolution within a VPC and does not apply to publicly accessible domains.
- C. Correct.
Correct: To make the Cloud DNS zone functional, you need to update the registrar's name servers to point to the Cloud DNS name servers.
- D. Incorrect.
Incorrect: Cloud DNS automatically provides redundancy and high availability for name servers, so no manual failover mechanism is needed.
- E. Correct.
Correct: Verifying DNS resolution ensures that the DNS records are configured correctly and accessible.
