A Client-to-Site VPN allows a remote user to securely connect to a company ' s internal network, providing access as if they were physically on-site.

Content filtering can be used to block or restrict access to websites and services that facilitate torrenting and other prohibited activities. By implementing content filtering, the company can comply with the ISP ' s cease-and-desist order and prevent users from accessing torrent sites and engaging in prohibited activities.References: CompTIA Network+ study materials.

The correct answer is B. NAT64 . This scenario says the internal network is using only IPv6 . In the real world, many internet services still rely on IPv4, so an IPv6-only client may need a translation mechanism to reach IPv4-based servers. That is exactly where NAT64 is used. It allows communication between IPv6-only clients and IPv4 resources by translating between the two protocols.

The other options do not solve that requirement. MPLS is used for traffic forwarding across provider networks and has nothing to do with IPv4/IPv6 protocol translation. GRE creates tunnels, but it does not automatically translate one IP version into another. Static routing can direct traffic, but it cannot make IPv6-only hosts speak to IPv4-only internet destinations.

From a Network+ perspective, this question is testing knowledge of IPv6 transition and interoperability mechanisms . If the network is entirely IPv6 internally, but still needs access to parts of the internet that may be IPv4, some translation service has to exist at the boundary. Among the choices given, NAT64 is the only technology that fits that role. That is why B is the best answer.
