Google Professional Cloud Network Engineer Question 565

Select 4Google Cloud Platform

You are setting up a GKE cluster to use Cloud DNS for managing DNS records dynamically. You decide to use the external-DNS operator to automate this process. Which of the following steps are required to properly configure external-DNS to work with Cloud DNS?

  1. A

    Grant the external-DNS service account the 'roles/dns.admin' role on the relevant Google Cloud project.

  2. B

    Deploy the external-DNS operator to the GKE cluster using a Helm chart or YAML manifests.

  3. C

    Enable the Compute Engine API to allow external-DNS to access Google Cloud DNS.

  4. D

    Configure external-DNS with a service account key file that has permissions to manage DNS records.

  5. E

    Create a Google Cloud DNS managed zone and specify the zone name in the external-DNS configuration.

Show answer and explanation

Correct answers: A, B, D, E

Explanation

To use external-DNS with GKE and Cloud DNS, you need to ensure proper authentication and configuration. This includes granting the external-DNS service account the correct permissions (roles/dns.admin), deploying the external-DNS operator to the cluster, and configuring it with a service account key file. Additionally, you must create a Cloud DNS managed zone and specify it in the external-DNS configuration to manage DNS records for that zone. Enabling the Compute Engine API is unrelated to this setup.

  • A. Correct.

    Correct. The external-DNS service account requires the 'roles/dns.admin' role to create, update, and delete DNS records in the managed zone.

  • B. Correct.

    Correct. Deploying the external-DNS operator to the GKE cluster is a necessary step to enable the automation of DNS record management.

  • C. Incorrect.

    Incorrect. Enabling the Compute Engine API is not required for external-DNS to function with Cloud DNS.

  • D. Correct.

    Correct. Configuring external-DNS with a service account key file that has the proper permissions is essential for authenticating with Google Cloud DNS.

  • E. Correct.

    Correct. You need to create a Cloud DNS managed zone and specify its details (e.g., zone name) in the external-DNS configuration to direct DNS record updates to the correct zone.
