H3C Constructing H3C High-Performance Campus Networks 認定 GB0-371-ENU 試験問題:
1. By viewing the IGMP group information, you can learn the following:
A) Multicast group IGMP querier
B) Multicast group information maintained by the router
C) The address of the first host of the multicast group to send a Report message
D) Number of multicast group Report packets
2. In the switching network as shown in the figure, VLAN10 is set as Super VLAN on the switch SWA, VLAN2 and VLAN3 are Sub VLANs of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to be judged by setting the IP address of each device as shown in the figure (choose one or more)
A) SWB can communicate with PCB
B) None of the above answers
C) SWB can communicate with PCA
D) SWB can communicate with PCC
E) SWB can communicate with SWA
3. In the network shown in the figure, the switch SWA is a two-layer switch, and the router RTA is the gateway of each PC. The following configuration is made on the router RTA:
[RTA]interface Ethernet 0/0.1
[RTA-Ethernet0/0.1]ip address 10.10.10.1 255.255.255.0
[RTA-EthernetO/0.1 ]vlan-type dotlq vid 1
[RTA-Ethernet0/0.1 Jinterface ethernet 0/0.2
[RTA-Ethernet0/0.2]ip address 20.20.20.1 255.255.255.0
[RTA-Ethernet0/0.2]vlan-type dotlq vid 2
[RTA-Ethernet0/0.2]interface ethernet 0/0.3
[RTA-Ethernet0/0.3]ip address 30.30.30.1 255.255.255.0
[RTA-Ethernet0/0.3]vlan-type dotlq vid 3
After completing the phase configuration on the switch SWA, PCA, PCB and PCC can all ping their own gateway. The following is correct about the switch SWA port Ethernet1/0/4 (choose one or more)
A) interface Ethernet1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all port trunk pvid vlan 3
B) interface Ethernet 1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all port trunk pvid vlan 10
C) interfaceEthernet1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all
D) interfaceEthernet1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all port trunk pvid vlan 2
4. In the PIM-DM networking, regarding the process of SPT formation (without considering the state refresh mechanism), the correct description is:
A) As long as the network topology and unicast routing information remain unchanged, the formed SPT tree will not change
B) The diffusion-pruning process is carried out periodically
C) The pruned interface no longer sends multicast packets downstream
D) After the process of flooding and pruning, an SPT between the multicast source and the multicast receiver is formed
5. The following statement about the three-layer switch is correct.
A) The three-layer switch functionally realizes the division of VLANs, the two-layer switching within the VLAN and the functions of inter-VLAN routing
B) The three-layer switch actually combines part of the functions of the two-layer switch and router, which improves the network integration and enhances the forwarding performance
C) The Layer 3 switch contains two parts: a Layer 2 VLAN forwarding engine and a Layer 3 forwarding engine
D) The three-layer forwarding engine of the three-layer switch is equivalent to the function of the router in the traditional networking, using hardware ASIC technology to realize the three-layer routing and forwarding across network segments
