ALCATEL LUCENT - Multicast Protocols Set 3

1.

Which of the following ranges is reserved for IPv6 SSM multicast address?

FF1X::/16 FF3X::/16 FF3X::/96 FF7X::/16

2.

Which of the following multicast packets can be forwarded on the Internet?

A multicast packet destined to FF70:: 1234 A multicast packet destined to FF1E:: 1234 A multicast packet destined to FF02:: 1234 A multicast packet destined to FF3A:: 1234

3.

If the access network supports IGMP version 2 only, what additional configuration is required to enable the SSM model?

IGMP snooping IGMP compatibility mode support IGMP version 2 to IGMP version 3 translations IGMP (*, G) Join to PIM (S. G) Join translation

4.

Which of the following statements is true regarding BSR and RP?

The same router cannot be configured as a BSR candidate and as a static RP The same router cannot be a candidate-RP and a BSR-candidate at the same time There is only one active RP in a multicast routing domain at anytime There is only one elected BSR in a multicast routing domain at anytime

5.

Why should the anycast RP address not be the system address of a router?

7750 SR configuration does not permit using the system address for an anycast address The system address of a router has to be a unique address within a domain while the anycast addressis configured on multiple routers within the domain PIM will not be able to establish its signaling sessions if the anycast address uses the system address None of the above

6.

Which statement best describes the impact of an RP failure in a PIM ASM network?

All the existing multicast traffic will be stopped immediately as PIM ASM network must have an RP in
order to transmit all the multicast traffic The multicast traffic will be impacted, but not immediately. Multicast routers will not discover the RPfailure until the timer expires and the multicast traffic flow will be stopped. No impact at all as RP is not required in a PIM ASM network The traffic will not be impacted if the multicast traffic flows have already been established and the trafficflow does not involve the RP in the path

7.

When forwarding a multicast frame, normal behavior for a LAN switch (without IGMP snooping enabled) is to forward the frame as if it were:

A unicast frame with a known destination in the forwarding table A unicast frame with an unknown destination in the forwarding table A unicast frame with a known source in the forwarding table A unicast frame with an unknown source in the forwarding table

8.

How many responses should be received if IGMP version 3 is in use and a router sends a Query to a specific multicast group that has 6 active receivers on the local broadcast domain?

1 2 6 7

9.

What multicast component has no function at all in a PIM SSM network?

The PIM routing protocol SSM translation on access multicast router The RP IGMP snooping

10.

How does the RP get the first multicast data packet from source?

Via the Source Path Tree Via a Register Message which encapsulates the multicast traffic Via a Bootstrap Message which encapsulates the multicast traffic Via the Shared Path Tree
