4: What command assigns the static IPv6 address fec0:0:0:1::1 to pseudo-interface 4 on Microsoft Windows XP?
A4: Answer:

ipv6 adu 4/fec0:0:0:1::1

or

netsh interface ipv6 add address 4 fec0:0:0:1::1

5: What do you do on Solaris 8 to enable IPv6 on interfaces hme0 and hme1?
A5: Answer: Creating /etc/hostname6.hme0 and /etc/hostname6.hme1 files and then rebooting the computer enables IPv6 on interfaces hme0 and hme1.
6: What command in Solaris 8 assigns the static IPv6 address fec0:0:0:1::1/64 to the hme0 interface?
A6: Answer: #ifconfig hme0 inet6 addif fec0:0:0:1::1/64 up
7: What pseudo-interface is assigned as the configured tunnel interface on Solaris 8?
A7: Answer: The logical interface ip.tun0
8: Based on the following table, what commands in Solaris 8 establish a configured tunnel? (Your node must use the source addresses.)
 IPv4IPv6
Source addresses10.100.50.20fec0:0:0:1000::2/128
Destination addresses192.168.1.50fec0:0:0:1000::1

A8: Answer:

#ifconfig ip.tun0 inet6 plumb

#ifconfig ip.tun0 inet6 addif fec0:0:0:1000::2/128 fec0:0:0:1000::1 up

9: What FreeBSD parameter enables stateless autoconfiguration on all interfaces?
A9: Answer: Adding the line ipv6_enable=“YES” in the /etc/rc.conf file enables stateless autoconfiguration on FreeBSD.
10: What command in FreeBSD enables the configured interface gif15?
A10: Answer: #ifconfig gif15 create
