최신 4A0-108 무료덤프 - Alcatel-Lucent Multicast Protocols

A. Provide more optimal routing of the Source Path Tree by allowing the receiver to connect to the closest multicast source

B. Used to support incongruent topologies

C. Provide more optimal routing of the Shared Path Tree by allowing redundant RPs to be located closer to receivers

D. Provide RP redundancy in a PIM SM network

E. Avoid the issue of shared-tree traffic concentration on a single RP in the network

A. Multicast CAC allows a service provider to guarantee the availability of mandatory IPTV channels

B. The aim of multicast CAC is to maintain the quality of existing IPTV channels by rejecting new channel joins when required

C. Multicast CAC policy can be applied to VPLS SAP and SDP with IGMP-snooping

D. Multicast CAC measures the current bandwidth utilization on the physical links and then decides whether to accept a new channel or not

A. FF00::/8

B. FF00::/16

C. FE00::/16

D. FE00::/8

A. Listen for announcements advertising available sessions from the source

B. Generate feedback to the network or source

C. Report their multicast group membership to their local router

D. Generate multicast data to the group

E. Signal their local router as they join and leave multicast groups

A. An IGMP join will be sent to the source

B. A PIM Assert message will be sent to the RP

C. The router will determine if it is the DR for that segment

D. The PIM source group database will be checked for the matching group

E. An RPF check will be performed on the packet

A. MP-BGP is more scalable than PIM.

B. An MPLS tunnel can be used instead of a GRE tunnel.

C. P routers in the core do not need to maintain any PIM group states.

D. Unicast and multicast traffic in the same VPRN service can use the same transport tunnel.

A. MP-BGP can also be used as the multicast signaling protocol between the PEs and CEs.

B. PIM state is maintained between PEs in the MVPN without PIM Hello messages.

C. MP-BGP keepalive messages are used to maintain adjacencies between the PEs in an MVPN.

D. If BGP Auto Discovery is used, MPLS LSPs must be used for the P-tunnels in the MVPN.

A. The selective tunnel signaling must be pim-asm.

B. The data-threshold group range must match the s-pmsi group range.

C. The MVPN configuration is correct, so there may be a problem with PIM in the core.

D. The selective tunnel configuration must be applied to the egress PEs as well.

A. Yes, that interface must be PIM-enabled.

B. If it is a physical interface, that interface should be PIM-enabled, otherwise it is unnecessary.

C. If the RPF check is using the multicast routing table, that interface should be PIM-enabled, otherwise it is unnecessary.

D. No, it is unnecessary to enable PIM on that interface.

A. IGMP snooping

B. TTL of 1 for IGMP messages

C. Formalized IGMP Querier election

D. Leave group message

E. Report suppression is eliminated

A. A packet with this address is never forwarded beyond the local link unless the TTL is greater than 1

B. A packet with this address is always forwarded throughout the multicast routing domain but never forwarded outside the multicast routing domain

C. A packet with this address is never forwarded beyond the local link regardless of the TTL

D. A packet with this address can only be processed by a router

A. 224.192.12.35 and 238.64.12.35
