JN0-102 · Question #26

What are three benefits of using IPv6? (Choose three.)

The correct answer is A. IPv6 supports a greater level of security by integrating features that were optional add- ons in IPv4. B. IPv6 reduces administrative overhead using stateless address autoconfiguration for hosts. C. IPv6 eliminates the need for private to public NAT using a large address pool. IPv6 offers enhanced security features, reduced administrative overhead through autoconfiguration, and eliminates the need for NAT due to its vast address space.

Why each option

IPv6 offers enhanced security features, reduced administrative overhead through autoconfiguration, and eliminates the need for NAT due to its vast address space.

AIPv6 supports a greater level of security by integrating features that were optional add- ons in IPv4.Correct

IPv6 integrates IPsec as a mandatory part of the protocol suite, providing a baseline for secure communication that was optional and less commonly deployed in IPv4.

BIPv6 reduces administrative overhead using stateless address autoconfiguration for hosts.Correct

Stateless Address Autoconfiguration (SLAAC) allows IPv6 hosts to automatically configure their own IP addresses and other network parameters, significantly reducing manual configuration and DHCP server dependency.

CIPv6 eliminates the need for private to public NAT using a large address pool.Correct

The significantly larger address space of IPv6 (2^128) provides enough unique public addresses for all devices globally, eliminating the need for Network Address Translation (NAT) between private and public IP address ranges.

DIPv6 provides backward compatibility with IPv4 using the Next Header field.

IPv6 is not backward compatible with IPv4; they are distinct protocols that require transition mechanisms for interoperation, and the Next Header field indicates the protocol following the IPv6 header, not compatibility.

EIPv6 represents large IP addresses using dotted decimal notation.

IPv6 addresses are represented using hexadecimal notation, not dotted decimal notation, which is used for IPv4 addresses.
