Question 1

What multicast addresses does RIPng use?

Accepted Answer

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.

Question 2

Which of the following is true when describing a multicast address?

Accepted Answer

Packets 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.

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.

Question 4

When a router is connected to a Frame Relay WAN link using a serial DTE interface, how is the clock rate determined?

Accepted Answer

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.

Accepted Answer

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.

Question 7

We want to assign port 3 of our Catalyst 2950 switch to VLAN 3. What command will achieve this?

Accepted Answer

Explanation: The switchport access vlan [number] command will configure a switch port to that VLAN.
