Which of the following is true when describing an anycast address?
Options
A. Packets addressed to a unicast address are delivered to a single interface.
B. Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
C. This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
Correct Answer
This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
Explanation
Anycast addresses identify multiple interfaces, which is the same as multicast; however, the big difference is that the anycast packet is only delivered to one address, the first one it finds defined in the terms of routing distance. This address can also be called one-to-one-of-many.

1. Which of the following commands will allow you to set your Telnet password on a Cisco router?
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.
3. 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.
4. 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.
6. 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.
