Google Professional Cloud Network Engineer Question 332

Select 3Google Cloud Platform

You are deploying a GKE (Google Kubernetes Engine) cluster in a VPC-native mode. Your organization wants to ensure that the cluster can scale horizontally in the future, and you need to configure the Pod IP ranges and Service IP ranges accordingly. During the deployment, you also need to add an additional Pod range to accommodate future workloads. What steps should you take to meet this requirement?

  1. A

    Ensure that the primary Pod IP range does not overlap with any other CIDR range in the VPC or with the Service IP range.

  2. B

    Configure the Service IP range to overlap with the Pod IP range to optimize IP address utilization.

  3. C

    Add a secondary IP range to the VPC subnet for the additional Pod range using the gcloud CLI.

  4. D

    Use the 'gcloud container clusters update' command to add the additional Pod range to the cluster.

  5. E

    Assign the additional Pod range to a subnet that is not used by the GKE cluster.

Show answer and explanation

Correct answers: A, C, D

Explanation

To properly configure Pod and Service IP ranges for a VPC-native GKE cluster, you must ensure that the Pod IP range does not overlap with the Service IP range or other ranges in the VPC. Additionally, to scale the cluster, you can add an additional Pod range by first creating a secondary IP range in the VPC subnet and then associating it with the cluster using the 'gcloud container clusters update' command. Overlapping or incorrectly assigned ranges can lead to IP address conflicts and routing issues.

  • A. Correct.

    Correct: The primary Pod IP range should not overlap with any other ranges in the VPC or the Service IP range to avoid IP conflicts.

  • B. Incorrect.

    Incorrect: The Service IP range must not overlap with the Pod IP range to prevent routing issues; overlapping ranges are not supported.

  • C. Correct.

    Correct: To add an additional Pod range, you must create a secondary IP range in the VPC subnet, which will be associated with the GKE cluster.

  • D. Correct.

    Correct: The 'gcloud container clusters update' command allows you to add additional Pod ranges to an existing GKE cluster.

  • E. Incorrect.

    Incorrect: The additional Pod range must be associated with the subnet used by the GKE cluster for IP address allocation.
