Explanation
B (Autoconfiguration) is correct: IPv6 supports Stateless Address Autoconfiguration (SLAAC), allowing devices to generate their own addresses without a DHCP server. C (No broadcasts) is correct: IPv6 eliminates broadcast addresses entirely, replacing broadcast functionality with multicast and anycast, which improves network efficiency. E (Plug-and-play) is correct: Related to SLAAC, IPv6 devices can self-configure and join a network without manual address assignment. A is incorrect: IPsec support is mandatory in IPv6 (not optional as it is in IPv4). D is incorrect: IPv6 actually has a simplified, fixed-length 40-byte header compared to IPv4's variable-length header, reducing processing overhead. F is incorrect: IPv6 removed the header checksum that existed in IPv4, delegating error checking to upper-layer protocols (TCP/UDP) to improve forwarding speed.
