91. In the wide area network IPv6 transition scenario, if "internal IPv4 and IPv6 terminals need to communicate with each other", which of the following technologies should be adopted?

IPv6 over IPv4 tunnel (only enables communication between IPv6 terminals)

NAT444 (only performs IPv4 address translation)

IPv4/IPv6 dual-stack technology (terminals support both protocols simultaneously, enabling direct interoperability).

DNS64+NAT64 (only enables IPv6 terminals to access IPv4 resources)

92. In Huawei's WAN bandwidth management solution, which of the following functions can "limit the bandwidth usage of non-critical services such as P2P downloads and ensure the bandwidth of core services (such as ERP)"?

Allocate bandwidth quotas for core services, without limiting them to non-critical services.

Application-based bandwidth limiting policies (P2P services are limited, core services are guaranteed bandwidth)

All services are allocated the same bandwidth, without any priority distinction.

Shut down non-critical services and only allow core services to access the network.
