What is the primary purpose of NAT44 in an IPv4 network?

To translate IPv6 packets into IPv4 packets so IPv6-only hosts can reach IPv4 servers

To provide a one-to-one mapping between a public IPv4 address and a private IPv6 address

To translate private IPv4 addresses to public IPv4 addresses for Internet connectivity

To encapsulate IPv4 packets inside IPv6 tunnels to traverse an IPv6-only network

Which statement accurately describes a characteristic of NAT44?

It is a stateless translation that does not require any session state on the translating device

It requires a dedicated tunnel concentrator to terminate IPv4-in-IPv6 tunnels

It translates both IPv4 and IPv6 addresses simultaneously in a dual-stack environment

It is a stateful translation that maintains a mapping table of private-to-public address and port translations

A regional ISP has exhausted its public IPv4 address pool but still has thousands of legacy DSL subscribers using IPv4-only CPEs. The ISP wants to continue serving these customers without deploying IPv6 to the home yet. Which solution should the ISP implement at its aggregation network to share a limited number of public IPv4 addresses among all these subscribers?

A service provider is rolling out IPv6 to residential customers but must preserve access to legacy IPv4-only services such as online banking portals. The provider's DNS infrastructure will be modified to synthesize AAAA records for IPv4-only domains. Which transition mechanism should the provider deploy at the network edge to enable IPv6-only subscribers to reach those IPv4-only services?

A service provider wants to offer IPv4 as a service over its new IPv6-only access network. The provider prefers a stateless solution that does not require maintaining per-subscriber state in the core and can scale horizontally without session limits. The CPE will be configured with a specific IPv6 prefix and a set of IPv4 addresses and port ranges derived from that prefix. Which mechanism should the provider choose?
