Which option is a primary requirement for the deployment of an IPv6-enabled network via the native method (dual-stack model) within the enterprise campus environment?

Question

Options

• Ahardware-based switching support for IPv6 forwarding on all campus switches
• Brestriction of IPv6-enabled devices to the core layer
• Cmanual implementation of tunneling between IPv6-incompatible devices in an IPv4-over-IPv6
• Ddisabling of multicast in the distribution layer prior to implementation of IPv6

• A
  90% (18)
• B
  5% (1)
• C
  5% (1)

Explanation

The native (dual-stack) IPv6 deployment model requires that every device in the network path simultaneously supports and forwards both IPv4 and IPv6 traffic. In a campus environment, this means all switches-especially in the access and distribution layers-must have hardware-based (ASIC-level) forwarding support for IPv6. Without hardware support, IPv6 packets would be processed in software (CPU), causing severe performance degradation. Tunneling is not native dual-stack (that's a transition mechanism), multicast is required by IPv6 (not disabled), and restricting IPv6 to only the core layer defeats the purpose of a dual-stack deployment.
