A network administrator is setting up a network that must support both IPv4 and IPv6. Which configuration approach allows the network devices to process IPv4 and IPv6 packets simultaneously, optimizing the handling of traffic without the need for extra translation mechanisms?
Dual stack
Tunneling
NAT64
Dual stack is the correct choice as it allows devices to run IPv4 and IPv6 simultaneously, providing seamless communication compatibility with both protocols. Dual stack avoids the complexities and performance hits associated with translating between IPv4 and IPv6, aligning directly with the needs specified in the question. Tunneling, although a valid approach for supporting IPv4 and IPv6, involves encapsulating IPv6 packets within IPv4 packets (or vice versa), which can introduce additional overhead and complexity. NAT64, on the other hand, translates IPv6 addresses into IPv4 addresses, which is not required in scenarios where systems support both protocols natively as is the case in dual stack configurations.
