Two colons (::) are used to represent successive hexadecimal fields of zeros.
Two colons (::) are used to separate fields.
A single interface will have multiple IPv6 addresses of different types.
Options
A. 1 and 3
B. 2 and 4
C. 1, 3 and 4
D. All of the above
Correct Answer
2 and 4
Explanation
In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed. Just as with IPv4, a single device's interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface.

1. How many collision domains are created when you segment a network with a 12-port switch?
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts-this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.
5. Which command is required for connectivity in a Frame Relay network if Inverse ARP is not operational?
If you have a router in your Frame Relay network that does not support IARP, you must create Frame Relay maps on your router, which provide known DLCI-to-IP address mappings.
6. What VTP mode allows you to change VLAN information on the switch?
A CIDR address of /19 is 255.255.224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
8. Which command will allow you to see real-time translations on your router?
Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure. You can see the topology table with the
show ip eigrp topology command.
