Question

An engineer is creating an IPv6 migration strategy with a transaction mechanism to provide the best performance possible. It should use native forwarding in hardware (if supported by the platform) and should add any encapsulation overhead. Which mechanism meets this requirement?

Options

BIPv6 Rapid Deployment
CDual stack
D6to4

Explanation

Dual stack is the only mechanism that runs IPv4 and IPv6 natively and simultaneously on every device with no encapsulation or tunneling. Because packets are forwarded natively, hardware ASICs can process them at line rate - meeting the 'native hardware forwarding' requirement. TEREDO (A), 6RD/IPv6 Rapid Deployment (B), and 6to4 (D) are all tunneling mechanisms that wrap IPv6 packets inside IPv4 headers, adding encapsulation overhead and typically requiring software-based processing, which degrades performance.
