Which of the following descriptions of dynamic NAT64 mapping is wrong when an IPv6 user accesses an IPv4 service?

Question

Options

• ADynamic NAT64 technology converts a large number of IPv6 addresses into a small number of
• BAfter receiving the response packets from the servers on the IPv4 network, the NAT64 device
• CThe NAT64 device creates a session table that records address mappings
• DDNS64 resolves the IPv4 service address and directly replies with the IPv4 address to the IPv6

• A
  14% (7)
• B
  6% (3)
• C
  2% (1)
• D
  78% (40)

Explanation

Resolution: After receiving the request packet, DNS64 parses the AAAA request, and if the IPv6 address cannot be resolved, it parses the A request, and finds that the service address is IPv4 ( 1.1.1.1), synthesizing the NAT64 address (64:FF9B::101:101) based on the configured Prefix64::/n(64:FF9B::/96). ), and then send it to the user to complete the address resolution. After receiving the DNS64 reply packet, the user sends the resolved address as the destination address to the remote server.
