A. B. C. D.Answer - C.
The AWS documentation mentions the following.
Your VPC can operate in dual-stack mode - your resources can communicate over IPv4, or IPv6, or both.
IPv4 and IPv6 communication are independent of each other.
For more information on VPC and IPv6 please refer to the below URL:
http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-migrate-ipv6.htmlAnswer: C. The VPC can operate in both IPv4 and IPv6.
When AWS claims that a VPC can operate in dual stack mode, it means that the VPC can support both IPv4 and IPv6 protocols simultaneously. This enables the VPC to communicate with resources that are using either protocol.
IPv4 is the most commonly used protocol today and is still widely used, but it is running out of address space. IPv6 is the next-generation protocol that offers a much larger address space, allowing for more unique IP addresses to be assigned. As the world transitions to IPv6, it is important for networks to support both IPv4 and IPv6 so that they can communicate with all resources on the internet.
By supporting both protocols, a VPC in dual stack mode can communicate with resources that are using either protocol. This is important for applications and services that may be running on different types of networks, such as public and private networks. It also ensures that the VPC can communicate with resources that are using IPv6, which is becoming more common as the world transitions to this protocol.
In conclusion, when AWS claims that a VPC can operate in dual stack mode, it means that the VPC can support both IPv4 and IPv6 protocols simultaneously, enabling it to communicate with resources that are using either protocol.
