An enterprise has plans to start adding IPv6 support. The initial deployment requires support
from some IPv6-only devices that need to access servers that support only IPv4. Which of
the following tools would be most appropriate?

A.
Native IPv6

B.
Point-to-point tunnels

C.
Multipoint tunnels

D.
NAT-PT

Explanation:

Native IPv6 makes the most sense when the IPv6 deployment is pervasive, with traffic loads
heavy or at least steady.. Point-to-point tunnels work best when IPv6 is needed in only a
subset of sites, but also when the traffic should be somewhat regular or with higher volumE.
Multipoint tunnels also work well when IPv6 is needed in a subset of sites, but it is more
appropriate when the traffic is more occasional and lower volumE. Finally, NAT-PT is useful
when an IPv4-only host needs to communicate with an IPv6-only host.
