Google Professional Cloud Network Engineer Question 204

Select 3Google Cloud Platform

Your company is planning to migrate its internal network to use IPv6 for improved scalability and global reachability. You are tasked with designing the network to ensure compatibility with Google Cloud services. What considerations should you include when planning for IPv6 in your Google Cloud environment?

  1. A

    Ensure that all Google Cloud load balancers are configured to use IPv6 addresses for front-end connections.

  2. B

    Verify that all Google Cloud services you use support dual-stack (IPv4 and IPv6) communication.

  3. C

    Migrate all internal VPC subnets to IPv6-only configurations to eliminate IPv4 address dependencies.

  4. D

    Plan for the use of Google Cloud global external IPv6 addresses for internet-facing applications.

  5. E

    Update IAM permissions to explicitly allow IPv6 traffic between Google Cloud resources.

Correct answers: A, B, D

Explanation

When planning for IPv6 in Google Cloud, ensure that services and configurations explicitly support IPv6, such as load balancers and external IPs. Verify dual-stack support since IPv6-only configurations are not currently supported in Google Cloud. Understanding these limitations and capabilities will help ensure a seamless transition to IPv6 in your environment.

  • A. Correct.

    Correct: Google Cloud load balancers support IPv6 for front-end connections, but this configuration must be explicitly enabled during setup.

  • B. Correct.

    Correct: Not all Google Cloud services currently support IPv6, so it's essential to verify dual-stack compatibility for the services you plan to use.

  • C. Incorrect.

    Incorrect: While IPv6 is highly scalable and future-proof, Google Cloud does not currently support IPv6-only VPC subnets. Dual-stack configurations are required, meaning IPv4 cannot be eliminated.

  • D. Correct.

    Correct: Google Cloud provides global external IPv6 addresses for internet-facing applications, which are crucial for enabling IPv6 connectivity for users.

  • E. Incorrect.

    Incorrect: IAM permissions are not dependent on the IP protocol version. You don't need to update IAM permissions specifically for IPv6 traffic.
