200-101 · Question #119

The network administrator has been asked to give reasons for moving from IPv4 to IPv6. What are two valid reasons for adopting IPv6 over IPv4? (Choose two.)

The correct answer is A. no broadcast E. autoconfiguration. IPv6 improves on IPv4 by eliminating broadcast traffic and enabling Stateless Address Autoconfiguration (SLAAC), reducing overhead and simplifying address management.

Question

The network administrator has been asked to give reasons for moving from IPv4 to IPv6. What are two valid reasons for adopting IPv6 over IPv4? (Choose two.)

Options

  • Bchange of source address in the IPv6 header
  • Cchange of destination address in the IPv6 header
  • DPing process does not require a password
  • Eautoconfiguration
  • FNAT

Why each option

IPv6 improves on IPv4 by eliminating broadcast traffic and enabling Stateless Address Autoconfiguration (SLAAC), reducing overhead and simplifying address management.

Ano broadcastCorrect

IPv6 replaces broadcast with multicast and anycast, eliminating the bandwidth waste and CPU overhead caused by broadcast traffic flooding all nodes on a segment.

Bchange of source address in the IPv6 header

Changing the source address in the IPv6 header is not a distinct advantage over IPv4; both protocols use source addresses in their headers in functionally equivalent ways.

Cchange of destination address in the IPv6 header

Changing the destination address in the IPv6 header is not an IPv6-specific advantage; destination addressing works similarly in both IPv4 and IPv6.

DPing process does not require a password

Whether ping requires a password is unrelated to the IPv6 protocol itself and is not a reason to adopt IPv6.

EautoconfigurationCorrect

IPv6 supports Stateless Address Autoconfiguration (SLAAC, RFC 4862), allowing hosts to automatically generate a global unicast address from the router-advertised prefix and their interface identifier without requiring a DHCP server.

FNAT

NAT is an IPv4 workaround for address scarcity; IPv6's vast address space eliminates the need for NAT, so NAT is not an advantage of adopting IPv6.
