Q9. In which way does the DS-Lite IPv6 transitioning mechanism differ from IPv6 Dual-Stack?
A. DS-Lite is a combination of tunnel and translation technologies.
B. DS-Lite is a transition technology that gives full IPv6 connectivity for IPv6 capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network.
