In HUAWEI CLOUD Stack, which of the following is a function of Destination Network Address...

The correct answer is D . Huawei’s official HUAWEI CLOUD Stack NAT Gateway documentation explains that DNAT is used to map the private IP address and port of a cloud server in a VPC to a public IP address and port by binding an EIP. In practical terms, DNAT allows requests that arrive at a public IP address to be forwarded to the private IP address of a server inside the cloud network. That matches option D exactly.

Option A describes SNAT , not DNAT. Huawei explicitly states that SNAT translates a private IP address into an extranet/public IP address so cloud servers can access the Internet. Option B is also related to SNAT behavior, because Huawei notes that multiple cloud servers in a VPC can share an EIP for outbound Internet access through SNAT. Option C describes a filtering or firewall-style function rather than NAT translation.

Therefore, in Huawei Cloud Stack networking, DNAT is specifically used for inbound mapping from public addresses to private cloud-server addresses , so the verified answer is D .
