Google Professional Cloud Network Engineer Question 159

Single answerGoogle Cloud Platform

Your organization is migrating workloads to Google Cloud and plans to establish a hybrid network between its on-premises data center and Google Cloud using a VPN. During the planning phase, you notice that your on-premises subnet range is 192.168.0.0/16, and the proposed Google Cloud subnet range is 192.168.1.0/24. What is the best course of action to avoid IP address conflicts when designing the IP address space?

  1. A

    Proceed with the current IP ranges, as Google Cloud automatically manages overlapping IP addresses.

  2. B

    Reconfigure the Google Cloud subnet to a non-overlapping range, such as 10.0.0.0/24.

  3. C

    Use NAT (Network Address Translation) on the VPN to avoid the IP overlap.

  4. D

    Split the on-premises subnet into smaller subnets to accommodate the Google Cloud subnet.

Show answer and explanation

Correct answer: B

Explanation

When extending a network to Google Cloud, IP address planning is critical to avoid overlapping ranges, which can lead to routing issues and connectivity problems. In this scenario, the on-premises subnet (192.168.0.0/16) overlaps with the proposed Google Cloud subnet (192.168.1.0/24). The best solution is to reconfigure the Google Cloud subnet to a completely non-overlapping range, such as 10.0.0.0/24. This ensures seamless communication between on-premises and cloud environments.

  • A. Incorrect.

    Google Cloud does not automatically handle overlapping IP ranges; manual planning is required to avoid conflicts.

  • B. Correct.

    Reconfiguring the Google Cloud subnet to a non-overlapping range, such as 10.0.0.0/24, is the correct approach to prevent IP conflicts between the on-premises and cloud environments.

  • C. Incorrect.

    While NAT could technically be used, it introduces unnecessary complexity and is not the optimal solution for avoiding IP address conflicts in this scenario.

  • D. Incorrect.

    Splitting the on-premises subnet does not resolve the fundamental issue of overlapping IP ranges between on-premises and Google Cloud.
