Question 41

What is the class D IP address range 239.0.0.0-239.255.255.255 used for?

It is a multicast address range used by routing protocols

Any legal multicast data flow and multicast application can use this address segment

Link-local multicast traffic mode up of network control messages meant to stay in the local subnet

It is a locally scoped multicast address and should only be used on local segments

It is an SSM multicast address range which is used on the entire network.

Question 42

Source Specific Multicast (SSM)is being used throughput the HW IP Multicast network. Which of the following three statements about SSM are true? (Choose three.)

SSM uses Shortest-Path Trees Only

There are no RPs to worry about

SSM is best suited for applications that are of the Many-to-Many category

SSM uses shared Trees only

The use of SSM is recommended when there are many sources and it is desirable to keep the amount of mroute state in the routers in the network to a minimum.

SSM is best suited for applications that are of one-to-many category

Question 46

Which of the following are differences between PIM-SM and PIM-DM? (Multiple Choice)

PIM-SM has RPTs and SPTs but PIM-DM has only RPTs

BSRs/RPs exist only on a PIM-SM network, not on a PIM-DM network

PIM-SM is applicable to a network with few receivers; PIM-DM is applicable to a network with a larger number of receivers

Whether in PIM-SM or PIM-DM mode, receiver hosts must join multicast groups through IGMP
