Exam N10-008 topic 1 question 864 discussion

EUI-64: allows the automatic generation of a 64-bit interface identifier for IPv6 addresses based on the device's MAC address. It helps ensure that each IPv6 address is unique to the device, incorporating the MAC address. SLAAC (Stateless Address Autoconfiguration): uses the EUI-64 method to generate IPv6 addresses automatically. It enables devices to configure their own IP addresses by combining the network prefix (advertised by routers) with the EUI-64 generated interface identifier. DHCPv6: While DHCPv6 can provide IPv6 addresses, it does not inherently use the MAC address in the same way EUI-64 does.

A. EUI-64 E. SLAAC EUI-64 (Extended Unique Identifier) is a method used in IPv6 addressing to automatically generate a unique address for each device by including its MAC address. SLAAC (Stateless Address Autoconfiguration) uses EUI-64 to assign addresses to devices on the network, allowing them to generate their own IPv6 addresses based on their MAC address. The other options do not relate to incorporating MAC addresses into IPv6 addressing. RFC1819 is outdated, APIPA is for automatic IP assignment in IPv4, DHCPv6 provides dynamic address allocation but doesn’t include MAC addresses, and CIDR is used for IP address allocation in IPv4.

A and D seem to be the only plausible choices.
