2V0-41.24 Question 170

Select 3

A company is transitioning its internal network from IPv4 to IPv6, but it needs to maintain communication with external web services that only support IPv4. The network administrator decides to use NAT64 to facilitate this communication. Which of the following correctly describes how NAT64 operates in this scenario?

  1. A

    NAT64 translates IPv6 packets to IPv4 packets, enabling IPv6-only clients to access IPv4-only services.

  2. B

    NAT64 requires both the client and the server to support dual-stack (IPv4/IPv6) for successful communication.

  3. C

    NAT64 works by mapping IPv6 addresses to IPv4 addresses and vice versa, based on a predefined translation mechanism.

  4. D

    NAT64 is typically used in conjunction with DNS64 to resolve DNS queries from IPv6 clients for IPv4-only resources.

  5. E

    NAT64 allows IPv4-only clients to initiate communication with IPv6-only servers without additional configuration.

Show answer and explanation

Correct answers: A, C, D

Explanation

NAT64 is a translation mechanism that allows IPv6-only clients to communicate with IPv4-only servers by converting IPv6 packets into IPv4 packets and vice versa. It works well in scenarios where IPv6 adoption is partial, enabling IPv6-only clients to access IPv4 resources. DNS64 is often used alongside NAT64 to resolve DNS queries for IPv6 clients attempting to reach IPv4-only resources. NAT64 does not, however, allow IPv4-only clients to communicate with IPv6-only servers, nor does it require both client and server to be dual-stack.

  • A. Correct.

    Correct. NAT64 enables IPv6-only clients to communicate with IPv4-only services by translating IPv6 packets into IPv4 packets.

  • B. Incorrect.

    Incorrect. NAT64 does not require both client and server to support dual-stack; it specifically facilitates communication between IPv6-only and IPv4-only networks.

  • C. Correct.

    Correct. NAT64 uses a translation mechanism to map IPv6 and IPv4 addresses, enabling seamless communication between the two protocols.

  • D. Correct.

    Correct. DNS64 works alongside NAT64 to resolve IPv6 client DNS queries for IPv4-only resources by synthesizing IPv6 addresses.

  • E. Incorrect.

    Incorrect. NAT64 does not allow IPv4-only clients to directly communicate with IPv6-only servers; it is designed for IPv6-to-IPv4 communication.
