Alcatel-Lucent Multicast Protocols - 4A0-108 模擬練習

A. MLD snooping snoops MLD report and done messages, but not query messages.

B. MLD snooping can co-exist with IGMP snooping in the same VPLS service.

C. MLD snooping enables switches to forward multicast data to specific hosts interested in the group.

D. Once MLD snooping is enabled, the switch can snoop both MLDv1 and MLDv2 messages.

A. Generate feedback to the network or source

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

C. Generate multicast data to the group

D. Report their multicast group membership to their local router

E. Listen for announcements advertising available sessions from the source

A. PIM ASM

B. PIM SSM

C. Either PIM SSM or PIM ASM

D. PIM DM

A. For broadcast delivery, the source will send a single copy of each packet regardless of the number of receivers

B. For unicast delivery, the source will send a single copy of each packet regardless of the number of receivers

C. For anycast delivery, the source will send a single copy of each packet regardless of the number of receivers

D. For multicast delivery, the source will send a single copy of each packet regardless of the number of receivers

A. There is no default setting, you must configure the version when you enable IGMP on 7750 SR

B. Version 2

C. Version 3

D. Version 1

A. Layer 7

B. Layer 3

C. Layer 1

D. Layer 2

E. Layer 4

A. The router floods the packet to all ports except the receiving port.

B. The router drops the packet.

C. The router floods the packet to all ports, including the receiving port.

D. The router forwards the packet.

A. PIM will not be able to establish its signaling sessions if the anycast address uses the system address.

B. Best practice is to use the system address as the anycast address for PIM.

C. The system address of a router must be a unique address within the domain, while the anycast address is configured on multiple routers within the domain.

D. Alcatel-Lucent 7750 SR configuration does not permit using the system address for an anycast RP address.

A. Forward the packet by default

B. Drop the packet by default

C. Flood the packet to all ports including the receiving port

D. Flood the packet to all ports except the receiving port

A. The MAC layer does not provide a means for identifying multicast traffic

B. Multicast MAC addresses do provide a unique representation of IP multicast addresses if the administrator configures the translation correctly

C. There are insufficient bits available in the multicast IP address to provide for a one to one relationship to a multicast MAC address

D. There are insufficient bits available in the multicast MAC address to provide for a one to one relationship to a multicast IP address

A. Never

B. Every 60 seconds

C. Every 30 seconds

D. Every 260 seconds

E. Every 120 seconds

A. The PE sends an (S, G) PIM Join with no encapsulation.

B. The PE sends a (*, G) PIM Join with no encapsulation.

C. The PE sends a (*, G) PIM Join with GRE encapsulation.

D. The PE sends an (S, G) PIM Join with GRE encapsulation.

A. There is one active source for 239.1.1.1 and two active sources for 239.2.2.2

B. There is a router on sdp 1000:500

C. There are no active sources in the network

D. The devices on sap 1/1/4 and sdp 1000:500 have issued joins for 239.1.1.1

A. Receivers are generally unknown by the source

B. All devices are potentially capable of generating multicast data

C. Receivers are generally known by each other since any receiver may be a source

D. Well suited for applications such as video on demand where each source sends a separate data stream to each of the many different receivers

E. Well suited for applications in which the receivers provide feedback to each other and the source
