What type of IPv6 address is the following?
FF01:0:0:0:0:0:0:2
16.
What is the compact format of the address
2102:0010:0000:0000:0000:fc23:0100:00ab?
a.
2102:10::fc23:01:ab
b.
2102:001::fc23:01:ab
c.
2102:10::fc23:100:ab
d.
2102:0010::fc23:01:ab
17.
When using the dual-stack backbone, which of the following statements is correct?
a.
The backbone routers have IPv4/IPv6 dual stacks, and end hosts do not.
b.
The end hosts have IPv4/IPv6 dual stacks, and backbone routers do not.
c.
Both the backbone routers and end hosts have IPv4/IPv6 dual stacks.
d.
Neither the backbone routers nor end hosts have IPv4/IPv6 dual stacks.
18.
How does a dual-stack host know which stack to use to reach a destination?
a.
It performs an ND, which returns the destination host type.
b.
It performs a DNS request that returns the IP address. If the returned address is
IPv4, the host uses the IPv4 stack. If the returned address is IPv6, the host uses
the IPv6 stack.
c.
The IPv6 stack makes a determination. If the destination is IPv4, the packet is
sent to the IPv4 stack.
d.
The IPv4 stack makes a determination. If the destination is IPv6, the packet is
sent to the IPv6 stack.
19.
What protocol numbers are used by Ethernet to identify IPv4 versus IPv6?
a.
Protocol 6 for IPv4 and protocol 17 for IPv6.
b.
0x86DD for IPv6 and 0x0800 for IPv4.
c.
0x8000 for IPv4 and 0x86DD for IPv6.
d.
0x0800 for both IPv4 and IPv6; they are identified in the packet layer.
20.
Which of the following describes the IPv6 header? (Select two.)
a.
It is 40 bytes in length.
b.
It is of variable length.
c.
The Protocol Number field describes the upper-layer protocol.
d.
The Next Header field describes the upper-layer protocol.
