Which method of ipv6 prefix assignment relies on the prefix contained in ra messages?

\( \newcommand\) • • • • IPv6 provides two competing ways for hosts to obtain their full IP addresses. One is DHCPv6, based on IPv4’s DHCP ( 7.10 Dynamic Host Configuration Protocol (DHCP)), in which the entire address is handed out by a DHCPv6 server. The other is StateLess Address AutoConfiguration, or SLAAC, in which the interface-identifier part of the address is generated locally, and the network prefix is obtained via prefix discovery. The original idea behind SLAAC was to support complete plug-and-play network setup: hosts on an isolated LAN could talk to one another out of the box, and if a router was introduced connecting the LAN to the Internet, then hosts would be able to determine unique, routable addresses from information available from the router. In the early days of IPv6 development, in fact, DHCPv6 may have been intended only for address assignments to routers and servers, with SLAAC meant for “ordinary” hosts. In that era, it was still common for IPv4 addresses to be assigned “statically”, via per-host configuration files. RFC 4862 [ SLAAC and DHCPv6 evolved to some degree in parallel. While SLAAC solves the autoconfiguration problem quite neatly, at this point DHCPv6 solves it just as effectively, and provides for greater administrative control. For this reason, SLAAC may end up less widely deployed. On the other hand, SLAAC gives hosts greater control over their IPv6 addresses, and so may end up offering hosts a greater degree of privacy by allowing en...

1. Which two statements are correct about IPv4 and IPv6 addresses? (Choose two.) • IPv4 addresses are 32 bits in length. • IPv6 addresses are 32 bits in length. • IPv6 addresses are represented by hexadecimal numbers. • IPv4 addresses are represented by hexadecimal numbers. • IPv6 addresses are 64 bits in length. • IPv4 addresses are 128 bits in length. Explanation: IPv4 addresses are represented as dotted decimal numbers and are 32 bits in length. IPv6 addresses are represented by hexadecimal numbers and are 128 bits in length. 2. Which network technology allows devices to communicate using both IPv4 and IPv6 addressing at the same time? • dual stack • SLAAC • tunneling • NAT64 Explanation: Dual stack allows IPv4 and IPv6 protocol stacks to function on devices at the same time. This allows devices to communicate on a network that uses both IPv4 addressing and IPv6 addressing simultaneously. 3. What is an advantage of using IPv6 ? • higher bandwidth • more frequencies • more addresses for networks and hosts • faster connectivity Explanation: An IPv6 address is comprised of 128 bits as opposed to 32 bits in an IPv4 address. Thus it offers far more addresses for networks and hosts than an IPv4 address does. 4. Which characteristic describes the default gateway of a host computer? • the physical address of the switch interface connected to the host computer • the logical address of the router interface on the same network as the host computer • the logical address assigned to...
