Question 6

In the PIM-DM network as shown in the figure, part of the unicast routing table of routers RT1 and RT2 is as follows

Then, the (S, G) entry and exit interface lists of routers RT1 and RT2 are respectively
  • Question 7

    Regarding root bridge protection, the following statements are correct
  • Question 8

    The customer's two switches SWA and SWB are connected together through seven Ethernet cables and configured with dynamic link aggregation. The corresponding ports on the switch SWA are Ethernet 1/0/1, Ethernet 1/0/2, and Ethernet 1/0. /3, Ethernet 1/0/4, Ethernet 1/0/5, Ethernet 1/0/6, Ethernet 1/0/7o If the switches SWA and SWB only support 6 ports per aggregation group, and the SWA switch has the following Configuration:
    [SWA]interface Ethernet 1/0/7
    [SWA-Ethernet1/0/7]lacp port-priority 4096
    Check LACP status on the device: output letter: as follows:
    [SWA]display lacp system-id
    Actor System ID: 0x8000, 00e1-fc00-5000
    [SWB]display lacp system-id
    Actor System ID: 0x8000, 00e0-fc43-7384
    If you change SWA's LACP system priority to 4096, you can know from the above information
  • Question 9

    What is correct about the STP root bridge?
  • Question 10

    Among the SNMPv1 messages, the messages sent by the Agent to the NMS include:
