C Nguyen The Nhat - Take Exam Exam questions Time remaining: 00: 38: 15 1 . How do you configure PIM? Use one global configuration command Use one global configuration command as well as enable PIM on each interface of the RP where you want to forward multicast traffic Use one interface command Use one global command and two interface commands 2 . PIM can support both dense-mode and sparse-modes simultaneously. True False 3 . Using IGMPv2, the RP with the _________ IP address on the segment is automatically elected as the multicast querier for the segment. highest lowest multicast destination 4 . By default, CGMP is: enabled (sai) disabled (sai) only enabled on the 1900/2820 switches (sai) disabled, except for the 2900XL (dung) 5 . Convert the multicast address 239.128.37.225 to its corresponding multicast MAC address. 01.00.00.00.25.e1 01.00.5e.00.25.e1 01.00.5e.25.00.e1 01.00.5e.e1.25.00 6 . In which of the following transmission methods are packets replicated on an as needed basis? Unicast Broadcast Multicast Overcast 7 . Using IGMPv1, what is a way that a host can join a multicast group? The host generates a segment query The RP generates a query message The RP generates a host membership report message The host must be currently in accept mode 8 . What are the two different types of messages shared by multicast hosts and multicast queries? Query messages Multicast messages Group messages Report messages 9 . Cisco does not support MOSPF. True (dung) False (sai) 10 . What are the IGMP default settings on a Catalyst 5000 switch? Snooping enabled and CGMP disabled (sai) Snooping disabled and CGMP enabled Snooping disabled and CGMP disabled (dung) Snooping enabled and CGMP enabled 11 . MOSPF works with OSPF by including information about segments that have an active multicast group in the OSPF link-state advertisements. True (dung) False 12 . What command is used to enable CGMP on an RP? cgmp set cgmp ip cgmp none of the above 13 . PIM, like MOSPF, requires OSPF. True (sai) False (dung) 14 . CGMP is best described by which of the following statements? CGMP uses a large amount of overhead It snoops IGMP queries/reports to learn end-station locations It has the switch interact with the RP to discover the location of multicast end-stations It has an effect on Layer 2 switching speeds of your Catalyst switches 15 . For CGMP to work: (Choose two) Only configure it on the switch Configure it on the switch Make sure it is running over a trunk link Configure it on the router 16 . Using IGMPv1, when a host wants to join a multicast group, it generates a _________ message. Group host Host membership report Member host Host generation 17 . How does a Layer 2 switch handle multicast traffic by default? Blocks it Sends it to all ports (dung) Sends it to all ports except the one it was received on Sends it only to the ports that request it 18 . What are the two different distribution modes that PIM uses for multicast routing? Common Uncommon Sparse Dense 19 . Most of the industry uses ________ routing protocols to set up their multicast distribution trees. single-mode multi-mode sparse-mode (dung) dense-mode 20 . As a design rule, what is the maximum time that should be allowed for a voice packet to cross a network? 60 milliseconds 120 milliseconds 150 milliseconds 210 milliseconds 21 . Convert the multicast address 224.48.77.32 to its corresponding multicast MAC address. 01.00.5e.30.4d.20 01.00.5e.00.4d.20 01.00.5e.4d.30.20 01.00.5e.20.4d.30 22 . The CGMP frame: is sent to 224.0.1.1 contains the multicast group address of the application allows Cisco routers to learn from IGMP-enabled switches contains the real MAC address of the end station (dung) 23 . Given the multicast address 225.192.222.174, to find the MAC address conversion, you would first have to convert this IP address to: 01.00.5e.40.e0.f5 224.64.222.174 225.320.222.174 225.64.222.174 24 . CGMP is best described by which one of the following statements? It has the switch examine IGMP report frames from end stations to learn where they are located It uses VLANs to contain multicast traffic It has the switch interact with the RP to discover the location of multicast end stations (dung) It uses manual configuration of multicast addresses in the CAM table Showing page 1 of 1 : 1Go! © 2004 HanoiCTT.
