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
- Ano broadcast
- Bchange of source address in the IPv6 header
- Cchange of destination address in the IPv6 header
- DTelnet access does not require a password
- Eautoconfiguration
- FNAT
Explanation
IPv6 improves on IPv4 by eliminating broadcast traffic and supporting stateless address autoconfiguration (SLAAC), reducing administrative overhead and network congestion.
Common mistakes.
- B. The ability to change a source address is not unique to IPv6 and is not a reason to migrate - both IPv4 and IPv6 support source address assignment.
- C. Changing the destination address is not a feature or advantage specific to IPv6 over IPv4.
- D. Telnet password requirements are a function of device configuration and security policy, completely unrelated to the IP version in use.
- F. NAT is a workaround required by IPv4 address exhaustion - IPv6's vast address space makes NAT unnecessary, so NAT is a drawback of IPv4, not a reason to adopt IPv6.
Concept tested. IPv6 advantages over IPv4 - broadcast elimination and SLAAC
