Google Professional Cloud Network Engineer Question 76
Select 3Google Cloud PlatformYou are designing a VPC network for a global e-commerce application that requires regional subnets for better traffic management and scalability. The application also needs to support both IPv4 and IPv6 traffic, and your organization wants to bring their own IP address range for the IPv4 subnets. Which of the following design considerations should you implement to meet the requirements?
- A
Allocate a custom subnet range for each region to ensure traffic is properly segmented.
- B
Enable IPv6 in your VPC and configure the subnets to use Google-provided IPv6 ranges.
- C
Bring your own IPv4 address range and reserve it in Google Cloud using an address allocation.
- D
Use a single global subnet to simplify traffic management across regions.
- E
Disable IPv6 to ensure compatibility with the organization's legacy systems.
Show answer and explanation
Correct answers: A, B, C
Explanation
To meet the requirements of the scenario, you need to ensure regional subnets for traffic segmentation, enable IPv6 for dual-stack support, and use the bring-your-own-IP (BYOIP) feature for IPv4 to integrate the organization's existing IP address range. Using a global subnet or disabling IPv6 would not fulfill the stated needs of the application.
- A. Correct.
Allocating a custom subnet range for each region ensures proper traffic segmentation, which is important for scalability and maintaining regional traffic control.
- B. Correct.
Enabling IPv6 in your VPC and using Google-provided IPv6 ranges is necessary to support IPv6 traffic, as requested in the requirements.
- C. Correct.
Reserving your organization's IPv4 address range in Google Cloud using the bring-your-own-IP (BYOIP) feature allows you to maintain consistency with your existing IP address management strategy.
- D. Incorrect.
Using a single global subnet does not align with the requirement for regional subnets and proper traffic management.
- E. Incorrect.
Disabling IPv6 contradicts the requirement to support both IPv4 and IPv6 traffic.
