Which network resources on GCP support IPv6?

The correct choice indicates that all global load balancers in Google Cloud Platform (GCP) support IPv6. This is significant because global load balancers are designed to distribute incoming traffic across multiple regions and can serve applications globally with higher availability and scalability. By supporting IPv6, these load balancers can handle requests from clients using both IPv4 and IPv6 addresses, which is essential for enabling modern internet applications that require a dual-stack approach to accommodate all users.

In contrast, other resources mentioned in the other choices do not universally support IPv6. For instance, while some virtual machine configurations might allow IPv6, restrictions apply depending on how the VM is set up, particularly with regard to network configurations and whether they are behind a load balancer that supports IPv6. Internal load balancers primarily focus on internal traffic and typically do not support IPv6. Only specific types of load balancers, such as the external HTTP(S) load balancer, support IPv6, but this is not comprehensive across all load balancers. Static IPs can support IPv6, but the scope is much narrower than what the global load balancers offer. Thus, choosing the option that encompasses all global load balancers clarifies the broader capability of GCP regarding IPv6
