質問 1：
The switches SWA and SWB are connected together through two optical fiber Gigabit Ethernet links, and the switch SWA has the following interface configuration:
[SWA]interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1]gvrp
[SWA-GigabitEthernet1/0/1]port link-type trunk
[SWA-GigabitEthernet1/0/1]port trunk permit vlan 1 10
[SWA]interface GigabitEthernet 1/0/2
[SWA-GigabitEthernet1/0/2]port link-type trunk
[SWA-GigabitEthernet1/0/2]port trunk permit vlan 1 10
If you want to configure link aggregation to aggregate these two links together, if the configuration on the SWB is correct, you can know from the above information
A. Only by changing the configuration of GigabitEthe1/0/2 to be consistent with GigabitEthe1/0/1, can they join the same aggregation group
B. Only when GigabitEthernet1/0/2 and Gigabit1/0/1 allow all VLANs to pass, they can join the same aggregation group
C. After link aggregation is configured on SWASWB, if both SWA and SWB enable MSTP on the aggregation port, one of GigabitEthe1/0/1 and GigabitEthe1/0/2 will be blocked
D. After link aggregation is configured on both SWA and SWB, if both SWA and SWB enable MSTP on the aggregation port, GigabitEthernet1/0/1 and GigabitEthe1/0/2 can participate in forwarding
正解：D

質問 2：
As shown in the figure, initially SWA is connected to SWB through E0/1, and SWB is connected to SWC through port E0/2. SWA and SWC are not directly connected. After enabling STP and waiting for its convergence, connect SWA to SWC, which leads to the switch port The change of STP status, the correct description of this change is
A. Both SWA port E0/2 and SWC port E0/1 will stay in the Listening state and the Learning state for one Forward Delay period.
B. SWC port E0/2 will go directly to Forwarding state from Listening state
C. Both SWB port E0/2 and SWC port E0/2 will stay in the Listening state and the Learning state for one Forward Delay period.
D. SWB port E0/2 will go directly to Blocking state from Forwarding state
正解：A,D

質問 3：
For the following configuration commands:
[H3C] ntp-service refclock-master 127.127.1.1 6
Understanding, which is correct
A. The device successfully configured with this command has a clock accuracy of 6 in stratum
B. This command configures the local clock as the reference clock of the system
C. The device successfully configured with this command can act as a clock server to provide external clock synchronization services
D. This command can be successfully configured on all H3C series switches
正解：A,B,C

質問 4：
Mid-to-high-end switch equipment has its own redundancy. If the dual main control board of a core switch in the customer's network is active and standby redundant hot backup, AC power supply 2+1 redundant hot backup, and fan system 1:1 hot backup, Then, among the following operations, which may have a significant impact on the customer network is
A. Pull out the standby main control board
B. Unplug 2 power supplies
C. Pull out 1 fan
D. Unplug the business board
正解：B,D

質問 5：
In the switching network as shown in the figure, all three switches only have the default VLAN1, the interconnection ports of the three switches are trunks, and all VLANs are allowed to pass, and the three switches have the global and port GVRP functions enabled. VLAN 10 is created on the switch SWA, VLAN 20 is created on the switch SWC, and the GVRP registration mode of the Ethernet 1/0/1 port is set to Fixed on the switch SWA, and the display vlan command is executed on the SWB to view the VLAN existing on VLASWB ( Select one or more)

A. VLAN1
B. VLAN 10
C. VLAN20
正解：A,B,C

質問 6：
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, allow all VLANs by setting the IP address of each device as shown in the figure, you can judge _ the following statement is correct

A. PCA packets enter from SWA's Ethernet1/0/1 port, and come out from Ethemet1/0/3 port without tag
B. PCA packets enter from the SWA Ethernet1/0/1 port, and come out from Ethemet1/0/3 port with VLAN Tag VLAN 1
C. The PCA message enters from the Ethernet1/0/1 port of SWA, and the VLANTag that comes out from the Ethernet1/0/3 port is VLAN2
D. The PCA message enters from the Ethernet1/0/1 port of SWA, and the VLANTag that comes out from the Ethernet1/0/3 port is VLAN 10
正解：C
