Select 3Google Cloud PlatformYour organization is planning to migrate its on-premises environment to Google Cloud and wants to enable IPv6 for its workloads. As a Cloud Network Engineer, you are tasked with designing the network. Which of the following are best practices when planning for IPv6 in Google Cloud?
- A
Use global load balancers to provide IPv6 connectivity to external clients.
- B
Allocate private IPv6 ranges for internal communication within Virtual Private Cloud (VPC) networks.
- C
Configure firewall rules to manage both IPv4 and IPv6 traffic.
- D
Use Cloud NAT to provide IPv6 outbound connectivity for VMs with only private IPv6 addresses.
- E
Verify that all services and applications support IPv6 before enabling it.
Show answer and explanation
Correct answers: A, C, E
Explanation
When planning for IPv6 in Google Cloud, it is essential to leverage features like global load balancers for external IPv6 connectivity, configure firewall rules for IPv6 traffic, and confirm that all services and applications support IPv6 before deploying it. IPv6 in Google Cloud is public and global, and Cloud NAT does not support IPv6, so these considerations are important for a successful implementation.
- A. Correct.
Correct: Global load balancers in Google Cloud support IPv6 for external connectivity, allowing clients to access your services via IPv6.
- B. Incorrect.
Incorrect: Unlike IPv4, IPv6 does not have private address ranges. In Google Cloud, IPv6 is always global and public by design.
- C. Correct.
Correct: Firewall rules are needed to explicitly allow or deny IPv6 traffic, just as they are for IPv4 traffic.
- D. Incorrect.
Incorrect: Cloud NAT does not support IPv6. It is used for providing outbound internet access to VMs with private IPv4 addresses.
- E. Correct.
Correct: Ensuring that all services and applications are IPv6-compatible is critical to avoid connectivity and operational issues when enabling IPv6.
