Google Professional Cloud Network Engineer Question 78
Select 3Google Cloud PlatformYour organization is migrating a multi-region application to Google Cloud and wants to ensure optimal IP address management. The application uses both IPv4 and IPv6 addresses. You are tasked with designing the subnets for the application while ensuring scalability and compliance with corporate policies. Which of the following considerations should you account for when planning the IP address management strategy?
- A
Ensure that each subnet's IP range does not overlap with other subnets in the same Virtual Private Cloud (VPC).
- B
Choose the largest possible subnet size (e.g., /16) for each region to avoid IP exhaustion.
- C
Use private IPv4 addresses and Google-provided IPv6 addresses for subnets, unless you plan to use Bring Your Own IP (BYOIP).
- D
Allocate IP ranges for each subnet that align with the corporate IP address management policies.
- E
Disable IPv6 in all subnets to simplify IP address management.
Show answer and explanation
Correct answers: A, C, D
Explanation
When planning an IP address management strategy on Google Cloud, it is critical to avoid overlapping subnets, ensure compliance with corporate policies, and utilize standard practices like private IPv4 and Google-provided IPv6 addresses. This approach ensures scalability, compliance, and efficient network segmentation. Disabling IPv6 is not recommended as it limits future scalability and dual-stack networking capabilities.
- A. Correct.
Ensuring that subnets' IP ranges do not overlap within the same VPC is essential to avoid routing conflicts and ensure proper network segmentation.
- B. Incorrect.
Choosing the largest possible subnet size is not a best practice as it can lead to inefficient IP utilization and does not account for potential scalability needs.
- C. Correct.
Using private IPv4 addresses and Google-provided IPv6 addresses is a standard practice unless specific compliance or BYOIP requirements are in place.
- D. Correct.
Aligning IP ranges with corporate IP address management policies ensures compliance and seamless integration with on-premises or other cloud networks.
- E. Incorrect.
Disabling IPv6 is not recommended as IPv6 adoption is growing, and Google Cloud supports dual-stack networking. Disabling it would hinder future scalability.
