You work as the network administrator for uCertify Inc. The company has planned to add the support for IPv6 addressing. The initial phase deployment of IPv6 requires support from some IPv6-only devices. These devices need to access servers that support only IPv4. Which of the following tools would be suitable to use?

A.
Multipoint tunnels

D.
Native IPv6
Answers
D.
Native IPv6
Suggested answer: B

Explanation:

NAT-PT (Network address translation-Protocol Translation) is useful when an IPv4-only host needs to communicate with an IPv4-only host. NAT-PT (Network Address Translation-Protocol Translation) is an implementation of RFC 2766 as specified by the IETF. NAT-PT was designed so that it can be run on low-end, commodity hardware. NAT-PT runs in user space, capturing and translating packets between the IPv6 and IPv4 networks (and vice-versa). NAT-PT uses the Address Resolution Protocol (ARP) and Neighbor Discovery (ND) on the IPv4 and IPv6 network systems, respectively.

NAT-Protocol Translation can be used to translate both the source and destination IP addresses.

Answer option D is incorrect. Native IPv6 is of use when the IPv6 deployment is pervasive, with heavy traffic loads.

Answer option C is incorrect. Point-to-point tunnels work well when IPv6 is needed only in a subset of sites. These point-to-point tunnels act as virtual point-topoint serial link. These are useful when the traffic is of very high volume.

Answer option A is incorrect. The multipoint tunnels are used for IPv6 deployment even when IPv6 is needed in a subset of sites and is suitable when the traffic is infrequent and of less predictable volume.
