D. automatic

E. static

F. functional

Suggested Answer: AB

While stateful and stateless NAT64 perform the task of translating IPv4 packets into IPv6 packets and vice versa, there are important differences. The following table provides a high-level overview of the most relevant differences.
Table 2. Differences Between Stateless NAT64 and Stateful NAT64
Stateless NAT64 Stateful NAT64 -
1:1 translation 1:N translation
No conservation of IPv4 address Conserves IPv4 address
Assures end-to-end address Uses address overloading, hence lacks transparency and scalability in end-to-end address transparency
No state or bindings created on the State or bindings are created on every translation unique translation
Requires IPv4-translatable IPv6 No requirement on the nature of IPv6 addresses assignment (mandatory address assignment requirement)
Requires either manual or DHCPv6 Free to choose any mode of IPv6 based address assignment for IPv6 address assignment viz. Manual, hosts DHCPv6,
