                 QUESTION: 61
                 A customer needs a network that can enable many users to request the same time-sensitive
                 information simultaneously. Which technology would meet this need?



                 A. Unicast
                 B. Multicast
                 C. Broadcast
                 D. Webcast



                 Answer: B



                 QUESTION: 62
                 Internet Group Management Protocol (IGMP) is used by IP Multicast routers to learn about the
                 existence of host  group members on their directly attached subnets. Which statement about
                 IGMP is true?



                 A.    The IP Multicast routers get this information by listening for IP hosts broadcasting IGMP
                 queries and reporting their host group memberships.
                 B.  The IP Multicast routers get this information by recognizing the modified MAC address of
                 a Multicast packet and adding that MAC address to the Multicast tree.
                 C.     The  IP Multicast  routers  get this information  by listening for Multicast Servers
                 broadcasting IGMP queries and listening for IP hosts reporting their host group memberships.
                 D.  The IP Multicast routers get this information by broadcasting IGMP queries and listening
                 for IP hosts reporting their host group memberships.



                 Answer: D




                 QUESTION: 63
                 A customer  has an Ethernet Routing  Switch (ERS)  8600 deployed as the core switch  to
                 provide connections to file servers. They have a file server that uses dual MAC addresses on
                 two Network Interface Cards (NICs) and need to provide as much bandwidth to the server as
                 possible. Which statement describes the process that will meet these requirements?




                                                             22












                 A. Configure a DMLT between both NICs and the ERS 8600.
                 B. Configure a MLT between both NICs and the ERS 8600.
                 C. Configure static ARP entries on the ERS 8600 to contain both MAC addresses.
                 D. Configure each port on the ERS 8600 as a separate link to each NIC.




                 Answer: D



                 QUESTION: 64
                 Multicast  transmission can result  in dropped packets or duplicate packets, and changes in
                 network topology can generate out-of-sequence packets. What protocol can minimize these
                 potential problems?



                 A. UDP
                 B. PGM
                 C. IGMP
                 D. QoS
