- Question
Which of the following is true when describing a multicast address?
Options- A. Packets addressed to a multicast address are delivered to a single interface
- B. packets are delivered to all interfaces identified with the address. This is also called a one-to-many address
- C. A multicast address identifies multiple interfaces and is delivered to only 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 with the address. This is also called a one-to-many address
ExplanationPackets addressed to a multicast address are delivered to all interfaces identified with 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.

Options- A. 802.1
- B. Frame Relay
- C. HDLC
- D. PPP Discuss

Correct Answer: FF02::9
Explanation:
RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
Correct Answer: FF02::A
Explanation:
EIGRPv6's multicast address stayed very near the same. In IPv4 it was 224.0.0.10; now it is FF02::A (A = 10 in decimal notation)
Correct Answer: Router1 (config - if) # ipv6 router rip 1
Explanation:
It's pretty simple to enable RIPng for IPv6. You configure it right on the interface where you want RIP to run with the ipv6 router rip number command.
Correct Answer: Router1 (config - if) # ipv6 ospf 10 area 0.0.0.0
Explanation:
To enable OSPFv3, you enable the protocol at the interface level as with RIPng. The command string is ipv6 ospf proces-id area area-id.
Correct Answer: Broadcasts have been eliminated and replaced with multicasts
Explanation:
There are no broadcasts with IPv6. Unicast , multicast, anycast, global, and link - local unicast are used.
Correct Answer: FE80::/10
Correct Answer: Frame Relay
Explanation:
The key is "there are no free ports" on your router. Only Frame Relay can provide a connection to multiple locations with one interface, and in an economical manner no less.
Correct Answer: Supplied by the CSU/DSU
Explanation:
Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your non-production test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.
Correct Answer: PPP
Explanation:
PPP is your only option because HDLC and Frame RElay do not support these types of business requirements. PPP provides dynamic addressing , authentication using PAP or CHAP, and callback services.
Correct Answer: DSL
Explanation:
ATM is the Data-Link layer protocol that's typically used over the DSL layer1 connection from the CPE and terminated at what's known as the DSLAM - an ATM switch that contains DSL interface cards, or ATU-Cs.
