Match each IPv6 addressing mechanism or special prefix construct on the left with its precise operational role or structural outcome on the right.
- Insertion of the 16-bit hexadecimal sequence 0xFFFE into the center of a 48-bit MAC addressExpands a standard 6-byte hardware MAC identifier into a 64-bit Modified EUI-64 interface identifier format
- Inversion of the Seventh Bit (U/L bit) in the first byte of an IEEE MAC addressDesignates global scope uniqueness for an autoconfigured Modified EUI-64 address
- Appending the lower 24 bits of a unicast IPv6 address to the prefix ff02::1:ff00:0/104Constructs a Solicited-Node Multicast address required for IPv6 Neighbor Discovery (ICMPv6)
- Combining the link-local scope prefix fe80::/10 (followed by 54 zero bits) with a 64-bit interface IDForms an automatically generated address restricted to single-segment local communication
Cevap
Each IPv6 structural mechanism matches its exact function: inserting 0xFFFE expands a 48-bit MAC address into a 64-bit interface ID; flipping the 7th bit sets global scope uniqueness in Modified EUI-64; appending the lowest 24 bits to ff02::1:ff00:0/104 generates a Solicited-Node Multicast address; and joining fe80::/10 with an interface ID yields a link-local unicast address.
The correct pairing aligns each IPv6 operational process with its corresponding technical outcome: 0xFFFE insertion expands 48-bit MACs to 64 bits; 7th bit inversion flags global scope in Modified EUI-64; combining lower 24 bits with ff02::1:ff00:0/104 produces the ICMPv6 Solicited-Node multicast address; and appending interface IDs to fe80::/10 creates link-local unicast addresses.
