Which of the following is true about Stateless Address Auto-configuration (SLAAC)?

Stateless Address Auto-configuration (SLAAC) is a key feature used in IPv6 networking that enables devices to generate their own IP addresses automatically without the need for manual configuration or a DHCP server. This self-configuration process occurs when a device listens for Router Advertisements on the network, which provide the necessary information such as the network prefix. Using this information, the device can create a valid IPv6 address on its own.

The other options do not align with the characteristics of SLAAC: a DHCP server is not required, as SLAAC is designed specifically to function independently of DHCP; it is exclusively utilized within IPv6 networks, as IPv4 has different mechanisms for address assignment; and SLAAC is fundamentally an automatic process rather than a manual configuration method. Therefore, the correct statement emphasizes the autonomous nature of SLAAC in configuring device addresses.
