최신 H3CSE-Routing & Switching GB0-371-ENU 무료샘플문제:

1. The customer LAN switches SWA, SWB, SWC, and SWD form an RRPP ring, the main ring 1. The switch SWD is connected to the switches SWB and SWC, but not to the switch SWA. The switch SWD has the following configuration information:
[SWD]rrpp domain 1
[SWD-rrpp-domain 1 ]ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0
If the switch SWA is the master node of primary ring 1, if the switch SWD port GigabitEthem1/0/ fails, you can know from the above information

A) If the switch SWD finds that the Gigabit port of the port is Up again, it will immediately unblock the port
B) SWA will send Link-Down messages to notify all nodes
C) The switch SWA immediately switches the state to the Failed state and releases the secondary port
D) The switch SWC immediately switches the state to the Failed state and releases the secondary port

2. What is the correct description of the architecture of SNMP v3?

A) An SNMP entity may be both SNMP Manager and SNMP Agent
B) SNMP engine includes scheduler, message processing subsystem, security subsystem and access control subsystem
C) SNMP Manager either has a generator or just a receiver
D) SNMP application includes command generator, command responder, instruction generator, instruction receiver, proxy forwarder, etc.

3. When the host receives the GeneralQuery message sent by the IGMPV2 querier, (choose one or more)

A) The host will send the Membership Report message only after receiving the GeneralQuery (GeneralQuery)
B) The host immediately sends the MembershipReport message
C) The destination address of the Report message is 224.0.0.1
D) The destination address of the Report message is the same as the GroupAddress address in the message

4. The following statements about the PIM SM registration suppression timer are correct (choose one or more)

A) To prevent the registration suppression timer from expiring, the DR will send the Register message encapsulating the multicast data to the RP before the timer expires
B) After receiving the registration stop message, the DR will update the registration suppression timer and continue to send data in multicast mode
C) After the RP receives the registration message from the DR, it will send a registration stop message and update the local (S, G) and (*, G) entries
D) The DR router of the multicast source will maintain a registration suppression timer. If the timer expires, the DR will unicast multicast source registration messages to the RP

5. 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

A) In the case of the same port configuration, Ethernet1/0/1 port is the aggregation group Unselected
B) When the configuration of each port is the same, the Ethernet1/0/7 port is the Unselected port of the aggregation group
C) When the configuration of each port is the same, SWA randomly selects one port among the six ports Ethem shot 1/0/1 to Ethernet 1/0/6 as the aggregation group UnselectM
D) In the case of the same port configuration, Ethernet1/0/6 port is the Unselected port of the aggregation group
