H3C Constructing H3C High-Performance Campus Networks GB0-371-ENU Prüfungsfragen mit Lösungen:

1. In the switching network as shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is the Secondary VLAN of VLAN20. After setting the IP address of each device as shown in the figure, the local proxy ARP function is enabled on both SWA and SWB. Initially, the switch and pc did not learn their corresponding ARP entries. In the process of PCA ping PCB, PCA will send an ARP request. After receiving the ARP request message, the PCA will send the destination MAC response. The destination MAC address is

A) 00E0.FC00.0020
B) 00E0.FC00.0010
C) 0011.1111.1111
D) FFFF.FFFF.FFFF

2. The figure shows the networking application of SmartLink and Monitor Link cascading. The Smart Link group on the switch SWH serves as the upstream port of the Monitor Link group on the switch SWH, and the opposite port of the downstream port of the Monitor Link group is the switch SWJ Smart Link group. The main port switch SWH upstream SWD and SWE ports are Smart Link group ports. It can be known from the above information

A) The switch SWH uplink switch SWE link is Down, then the main port of the switch SWJSmart Link group will be switched to the secondary port
B) Switch SWH upstream switch SWD link is Down, then the main port of the switch SWJSmart Link group will be switched to the secondary end
C) Switch SWH uplink switch SWD and SWE links are in Down state, then the main port of the switch SWJSmart Link group will be switched to the secondary port
D) Switch SWJSmart Link group status has nothing to do with switch SWH

3. The following statements about the PIM joining process are correct:

A) The multicast joining path of DR in PIMDM is the optimal forwarding path from source to DR
B) The multicast joining path of DR in PIMSM is the optimal forwarding path from source to DR
C) The RP's multicast source joining path in PIMSM is the optimal forwarding path from the source to the RP
D) The multicast joining path of DR in PIMSSM is the optimal forwarding path from source to DR

4. In the switching network as shown in the figure, set VLAN10 as Isolate-userW VLAN2 and VLAN3 as the Secondary VLAN of VLAN 10 on the switch SWA; create VLAN2? VLAN20 on the switch SWB, and set VLAN20 as Isolate-user-vlan, VLAN4 For the Secondary VLAN of VLAN20, after setting the IP address of each device as shown in the figure, which statement is correct (choose one or more)

A) The PCA packet comes out of the GigabitEthem1/0/port of SWA and enters the GigabitEthem1/0/4 port of SWB. The VLAN tag carried is VLAN20
B) The PCA packet enters from the GigabitEthem1/0/1 port of SWA, and the VLAN tag after exiting from the GigabitEthem1/0/3 port is VLAN2
C) SWB packets enter from SWA's GigabitEthem1/0/3 port, and after exiting from GigabitEthem1/0/3 port, the VLAN Tag carried is VLAN20
D) When SWB accesses PCA, the VLAN tag carried by GigabitEthem1/0/4 of SWB is VLAN 10

5. Which of the following addresses is not an IPv4 multicast address?

A) 232.255.255.255
B) 239.255.255.255
C) 224.0.0.13
D) 242.255.255.250
