Q17Network Design
Company XYZ is migrating its existing network to IPv6 and must plan for Layer 2 and Layer 3 devices. Some access-layer switches do not support IPv6; however, the core and distribution switches fully support unicast and multicast routing. The company wants to minimize migration costs. Which migration strategy should be used in the design?

I agree with you, but...
1. they want to minimize the cost and legacy L2 switches will pass IPv6;
2. Legacy switches should not affect migration, but will affect operation;
I'm not sure :-).
C 2
Selected Answer: C
layer 2 switches can still affect the implementation of IPv6, especially if they do not support features like Neighbor Discovery Protocol (NDP) and Stateless Address Autoconfiguration (SLAAC).
D 2
Selected Answer: D
they can use dual stack or address translation while migrating
D 2
Selected Answer: D
I don't see multicast requirements in the question

I agree with piz... you cannot say old L2 switch cannot configure IPv6 ACL... less money less requirement

The correct answer is:
D. Layer 2 switches will not affect the implementation of IPv6. They can be included in the design in their current state.Layer 2 switches (which operate at the data link layer) do not have to fully support IPv6 to carry IPv6 traffic. The primary job of Layer 2 switches is to forward Ethernet frames based on MAC addresses, and they are agnostic to the Layer 3 protocols (IPv6 or IPv4). As long as the Layer 2 devices are working properly and not blocking IPv6 traffic at the data link layer, they can keep operating in their current state during the migration.
