Networking Chapter 6
Which of the following addresses is a valid IPv6 address A. 192.168.1.256 B. 10.1.25.2 C. 2001:0000:4137:9e76:3c2b:05ad:3f57:fe98 D. 2001:0000:4137:9g76:3c2b:05zd:3x57:gh98
C IPv6 addresses are expressed as groups of hexadecimal characters. Valid hexadecimal characters are 0 through 9 and a through f. Characters such as x, g, and h are not valid.
Which of the following features is built into IPv6 to provide extra security A. Teredo tunneling B. Global addresses C. Unique local addresses D. IPSec
D Internet Protocol Security (IPSec) is built into IPv6 and allows IPv6 to easily encrypt traffic.
You need to assign IPv6 addresses to hosts on a private network. You should use _____________ addresses.
unique local addresses Unique local addresses are assigned to hosts on private networks.
What IPv6 protocol is used to identify routers on the same network A. Network Discovery B. Teredo C. IGMP D. Anycast
A Network Discovery uses ICMPv6 messages for router discovery
You need to manually assign an IPv6 address to a client computer for use within a private network. Which one of the following addresses should you use? A. 0000::a123:4567:89ab:cdef B. 2001:0001::fcde:ba98:7654 C. 2001:0000: fcde:ba98:7654 D. fe80:: a123:4567:89ab:cdef E. fd00:: a123:4567:89ab:cdef
E Unique local addresses are assigned as private addresses. They have a prefix of fd hexadecimal.
True or false. An IPv6 address with a prefix of fd is a link-local address.
False The IPv6 prefix of fd is for unique local addresses. Link-local addresses have a prefix of fe80.
What IPv6 to IPv4 technology uses tunneling to encapsulate an IPv6 packet within an IPv4 packet?
Teredo Teredo is a tunneling protocol that encapsulates IPv6 packets within IPv4 datagrams. A lesser used protocol is 6to4, which can also be a valid answer.
IPv4 addresses use public address on the Internet. IPv6 uses _____________ addresses on the Internet.
global unicast Global unicast addresses are used on the Internet. They have a prefix of 2.
