In the network connection shown in the figure, SWA and SWB are three-layer switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and the master of VRRP, and SWC is the downlink access terminal of the two-layer switch. Which of the following description of the network link failure is correct?
- A . When the link between SWA and SWB is disconnected, the STP topology will change, and both uplink ports of SWC will become Forwarding
- B . When the link between SWA and SWB is disconnected, the VRRP Master will switch and SWB will become the new VRRP Master
- C . When the link between SWA and SWC is disconnected, the STP topology will change, and G1/0/2 of SWC will become Forwarding
- D . After the link between SWA and SWC is disconnected, the VRRP Master will remain unchanged, but the SWC downstream terminal will not communicate with the gateway.
The customer’s two switches SWA and SWB are connected together through seven Ethernet cables and configured with static link aggregation. The corresponding ports on switch SWA are Ethernet 1/0 Ethernet 1/0/2, Ethernet 1/0/3, Ethernet 1/0/4, Ethernet 1/0/5, Ethernet 1/0/6, and Ethernet 1/0/7. The configuration method is to configure in sequence according to the port order. If each aggregation group of switches SWA and SWB only supports 6 ports, then which of the following is right?
- A . When all ports are configured the same, Ethernet 1/0/1 is the Unselected port in the aggregation group.
- B . When the configuration of each port is consistent, SWA randomly selects one port from the seven ports as the Unselected port of the aggregation group.
- C . When all ports are configured the same, Ethernet 1/0/6 is the Unselected port in the aggregation group.
- D . When all ports are configured the same, Ethernet 1/0/7 is the Unselected port in the aggregation group.
Which of the following statements about STP bridge ID is correct?
- A . The bridge with the smallest bridge ID in the network will eventually become the root bridge after STP calculation.
- B . The bridge ID consists of the bridge MAC address and the priority field. When comparing bridge IDs, the MAC address is compared first, and the one with the smaller MAC address value is preferred.
- C . The MAC addresses of SWA and SWB are 00-E0-FC-00-00-11 and 00-E0-FC-11-00-11 respectively, and their priorities are 32768
and 4096, when SWA and SWB are connected in a ring network and the spanning tree protocol is enabled, SWA will become the root bridge. - D . The bridge priority field is 2 bytes long, so the bridge priority value range is 0-65535
Which request operation does SNMP v2c add compared to SNMP v1 protocol?
- A . GetRequest
- B . GetNextRequest
- C . GetBulkRequest
- D . SetRequest
In the switching network shown in the figure, VLAN 10 is set as the Super VLAN on the switch SWA, and VLAN2 and VLAN3 are sub VLANs of VLAN 10. VLAN, port Ethernet1/0/3 is a Trunk port, PVID is VLAN1, and all VLANs are allowed to pass; VLAN2 and VLAN20 are created on switch SWB, port Ethernet1/0/4 is a Trunk port, PVID is VLAN1, and all VLANs are allowed to pass. After setting the IP addresses of each device as shown in the figure, you can judge which of the following is correct?
- A . PCC can communicate with PCB
- B . PCC can communicate with SWA
- C . PCC can communicate with SWB
- D . SWA can communicate with SWB
Which of the following statements about the intercommunication between Sub VLANs in Super VLAN technology is correct?
- A . The host IP addresses in different Sub VLANs belong to the same network segment, and they can communicate directly with each other through Layer 2 forwarding.
- B . The host IP addresses in different Sub VLANs belong to the same network segment, but due to the isolation of Sub VLAN, the Sub VLANs cannot communicate with each other.
- C . Hosts in different Sub VLANs are isolated at Layer 2, and can communicate at Layer 3 through the common proxy ARP technology of the Super VLAN interface.
- D . Hosts in different Sub VLANs are isolated at Layer 2, and can communicate at Layer 3 through the local proxy ARP technology of the Super VLAN interface.
The customer LAN switch SWA is connected to multiple switches. If it is known that the Monitor Link group is configured on SWA, the switch SWA has the following configuration information:
[SWA] monitor-link group 1
[SWA-mtlk-group1] port gigabitethernet 1/0/1 uplink
[SWA-mtlk-group1] port gigabitethernet 1/0/2 uplink
[SWA-mtlk-group1] port gigabitethernet 1/0/3 uplink
[SWA-mtlk-group1] port gigabitethernet 2/0/1 downlink
What can we learn from the above information?
- A . If the GigabitEthernet1/0/1 port is in the Down state, the GigabitEthernet 2/0/1 port will also be in the Down state.
- B . If the GigabitEthernet1/0/2 port is in the Down state, the GigabitEthernet 2/0/1 port will also be in the Down state.
- C . If the GigabitEthernet1/0/2 port is in the Down state, the GigabitEthernet 2/0/1 port will also be in the Down state.
- D . If the GigabitEthernet1/0/1 port is in the Up state, the GigabitEthernet 2/0/1 port will also be in the Up state.
The customer’s LAN switch SWA has dual uplink connections to switches SWB and SWC, and Smart Link is used to ensure link reliability. What can we learn from the above information?
- A . If the configuration of each port is consistent, you can select the SWA aggregation member port as the Smart Link port.
- B . If the configuration of each port is consistent, you can select the SWA RRPP member port as the Smart Link port
- C . If the configuration of each port is consistent, you can select the SWA STP member port as the Smart Link port
- D . None of the above answers are correct
Two switches SWA and SWB are connected together through four Ethernet cables, and the corresponding interfaces on switch SVVA have the following configuration:
[SWA-Ethernet1/0/1] display this duplex full
Speed 10

Speed 10
[SWA-Ethernet1/0/3] display this duplex half
Speed 100
[SWA-Ethernet1/0/4] display this duplex half
Speed 100
