Google Professional Cloud Network Engineer Question 203
Select 2Google Cloud PlatformYour organization is planning to adopt IPv6 for its Google Cloud environment to support future scalability and meet compliance requirements. You have an existing VPC network with subnets configured for IPv4. What steps must you take to enable IPv6 within the VPC network while ensuring a smooth transition?
- A
Enable an IPv6 stack on the VPC network and configure global IPv6 addresses for your resources.
- B
Assign an IPv6 range to the existing subnets within the VPC.
- C
Create a new VPC network configured exclusively for IPv6 and migrate resources over.
- D
Update the firewall rules to allow IPv6 traffic as required by your application.
- E
Enable IPv6 in the default VPC network to serve as a test environment before applying it to your custom VPC.
Show answer and explanation
Correct answers: B, D
Explanation
To enable IPv6 in an existing VPC network, you need to assign IPv6 ranges to the subnets and ensure that firewall rules are updated to manage IPv6 traffic effectively. Enabling IPv6 does not require creating a new VPC, nor does it necessitate testing on the default VPC unless explicitly desired for experimentation. These steps ensure that your VPC network is properly configured to support IPv6 traffic while maintaining security and functionality.
- A. Incorrect.
This is incorrect because enabling an IPv6 stack alone is not sufficient. You also need to assign IPv6 ranges to subnets and configure other resources to handle IPv6 traffic.
- B. Correct.
This is correct because assigning an IPv6 range to your existing subnets is required to enable IPv6 connectivity within the VPC network.
- C. Incorrect.
This is incorrect because creating a new VPC exclusively for IPv6 is not necessary. Google Cloud allows you to add IPv6 ranges to existing subnets within a current VPC network.
- D. Correct.
This is correct because updating firewall rules to permit IPv6 traffic is essential for allowing external and internal IPv6 communication as per your application needs.
- E. Incorrect.
This is incorrect because while using the default VPC for testing is a valid approach for experimentation, it is not required to enable IPv6 in your custom VPC.
