- Question
Which of the following is true when describing a multicast 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 a one-to-many address.
- C. Identifies multiple interfaces and 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
- Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.
ExplanationPackets addressed to a multicast address are delivered to all interfaces identified by the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with FF. - 1. Which of the following commands will allow you to set your Telnet password on a Cisco router?

Correct Answer: line vty 0 4
Explanation:
The command
line vty 0 4 places you in a prompt that will allow you to set or change your Telnet password.
Correct Answer: 255.255.255.224
Explanation:
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.
Correct Answer: frame-relay map
Explanation:
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.
Correct Answer: Server
Explanation:
Only in server mode can you change VTP information on a switch.
Correct Answer: 8 subnets, 8,190 hosts each
Explanation:
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.
Correct Answer: debug ip nat
Explanation:
The command
debug ip nat will show you in real time the translations occurring on your router.
Correct Answer: 802.1Q
Explanation:
802.1Q was created to allow trunked links between disparate switches.
Correct Answer: show ip eigrp topology
Explanation:
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.
Correct Answer: PPPoE
Explanation:
PPPoE encapsulates PPP frames in Ethernet frames and uses common PPP features like authentication, encryption, and compression. PPPoA is used for ATM.
Correct Answer: PAT
Explanation:
Port Address Translation (PAT) allows a one-to-many approach to network address translation.
