Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Dual-stack approach refers to
A
implementing Ipv4 with 2 stacks
B
implementing Ipv6 with 2 stacks
C
node has both IPv4 and IPv6 support
D
implementing a MAC address with 2 stacks
Explanation: 

Detailed explanation-1: -Explanation: Dual-stack is one of the approaches used to support IPv6 in already existing systems. ISPs are using it as a method to transfer from IPv4 to IPv6 completely eventually due to the lower number of possible available addresses in IPv4.

Detailed explanation-2: -IPv4 and IPv6 Coexistence via Dual Stack Dual stack is the most basic and direct strategy to achieve IPv4 and IPv6 coexistence. With this solution, every networking device, including using IPv4 or IPv6 switches, in an ISP’s network will be configured with the capabilities to run IPv4 and IPv6 simultaneously.

Detailed explanation-3: -Implementing Dual-Stack However, in the context of IPv6 transition, dual-stack means a protocol stack that contains both IPv4 and IPv6.

Detailed explanation-4: -Dual-stacking means running IPv4 and IPv6 in the same network. It gives IPv6 compatible devices the choice of which to use, and while still limited to the number of IPv4 addresses available, has the benefit of having an IPv6 deployment ready for migration.
