The Ethernets port of switch SWA is configured as follows:
Interface Ethernet 1/0/1 port link-type trunk
Port trunk permit vlan 10 port trunk pvid vlan 20
Now we need to change the Ethernet 1/0/1 port of switch SWA to a Hybrid port, with PVID of VLAN 20, and do not tag the data frames of VLAN 20 when sending them, but tag the data frames of VLAN 10 when sending them. Which of the following configuration processes is correct?
- A . [SWA-Ethernet1/0/1] port link-type access
[SWA-Ethernet1/0/1] port access vlan 20
[SWA-Ethernet1/0/1] port link-type hybrid
[SWA-Ethernet1/0/1] port hybrid vlan 10 tagged - B . [SWA-Ethernet1/0/1] portlink-type access
[SWA-Ethernet1/0/1] port link-type hybrid
[SWA-Ethernet1/0/1] port hybrid pvid vlan 20
[SWA-Ethernet1/0/1] port hybrid vlan 10 tagged - C . [SWA-Ethernet1/0/1] undoportlink-type
[SWA-Ethernet1/0/1] portlink-typeHybrid
[SWA-Ethernet1/0/1] port hybrid pvid vlan 20
[SWA-Ethernet1/0/1] port hybrid vlan 10 tagged - D . [SWA-Ethernet1/0/1] port link-type hybrid
- E . None of the above is correct
The IP address of host PCA is 40.1.1.1, and the MAC address is 0011.1111.1111. PCA is connected to [SWA] vlan 10 of switch SWA.
[SWA-vlan10] quit
[SWA] vlan 20
[SWA-vlan20] protocol-vlan ipv4
[SWA-vlan20] quit
[SWA] vlan 30
[SWA-vlan30] quit

[SWA-vlan40] ip-subnet-vlan ip 40.1.1.0 255.255.255.0
[SWA-vlan40] quit
[SWA] interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1] port link-type hybrid
[SWA-GigabitEthernet1/0/1] port hybrid pvid vlan 10
[SWA-GigabitEthernet1/0/1] port hybrid vlan 10 20 30 40 untagged
[SWA-GigabitEthernet1/0/1] port hybrid protocol-vlan vlan 20 0
[SWA-GigabitEthernet1/0/1] port hybrid ip-subnet-vlan vlan 40
[SWA-GigabitEthernet1/0/1] mac-vlan enable

After the configuration is completed, which of the following can be determined that PCA will join?
- A . VLAN 10
- B . VLAN20
- C . VLAN30
- D . VLAN40
E The configuration command is incorrect.
In the switching network shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, and VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN4 and VLAN20 are created on switch SWB, and VLAN20 is set as Isolate-user-vlan and VLAN4 is set as Secondary VLAN of VLAN20. After setting the IP addresses of each device as shown in the figure, the local proxy ARP function is enabled on SWA and SWB. Initially, the switch and PC did not learn their corresponding ARP entries. When PCA pings PCB, PCA will send an ARP request. After PCB receives the ARP request message, it sends a destination MAC response with the destination MAC address as?
- A . FFFF.FFFF.FFFF
- B . 0011.1111.1111
- C . 00E0.FC00.0010
- D . 00E0.FC00.0020
Which of the following mirroring technology that can achieve cross-switch?
- A . Port mirroring
- B . Flow mirroring
- C . Remote Mirroring
- D . Local mirror
In the network shown in the figure, the corresponding configuration is completed on the switch SWA, and the switch SWA and each PC have learned the corresponding ARPPCA. When accessing PCB, ICMP request message is sent, and the destination MAC address of the message is?
- A . FFFF.FFFF.FFFF
- B . MAC-10
- C . MAC-20
- D . MAC-B
Two switches SWA and SWB are connected together through four Ethernet cables. The corresponding ports on switch SWA are Ethernet 1/0/1, Ethernet 1/0/2, Ethernet 1/0/3, and Ethernet 1/0/4. Static link aggregation is configured for these four ports on SWA. What can we learn from the above information?
- A . When all ports are configured the same, Ethernet 1/0/1 is the reference port for the aggregation group.
- B . When all ports are configured the same, Ethernet 1/0/2 is the reference port for the aggregation group.
- C . When the configuration of each port is consistent, Ethernet1/0/3 port is the reference port of the aggregation group
- D . If all ports are configured the same, Ethernet 1/0/4 is the reference port for the aggregation group.
The customer LAN switches SWA, SWB, SWC, and SWD form the RRPP ring main ring 1. Switch SWD is connected to switches SWB and SWC, but not to 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 switch SWA is the master node of primary ring 1, and if switch SWD port GigabitEtherent2/0/1 fails, what can we learn from the above information?
- A . SWA will send a Link-Down message to notify all nodes
- B . The switch SWA immediately switches to the Failed state and releases the secondary port
- C . The switch SWC immediately switches to the Failed state and releases the secondary port.
- D . If the switch SWD finds that the port GigabitEthernet2/0/1 is Up again, it will immediately unblock the port.
Two routers are connected together through a LAN to form a VRRP backup group. The configuration on each interface is as follows:
[RTA-GigabitEthernet1/0] display this
IP address 192.168.0.252 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.0.254
Vrrp vrid 1 priority 120 shut down.
[RTB-GigabitEthernet1/0] display this
IP address 192.168.0.253 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.0.254
What can we learn from the above information?
- A . Router RTA is in VRRP Master state, and router RTB is in VRRP Backup state.
- B . Router RTA is in VRRP Backup state, and router RTB is in VRRP Master state
- C . Router RTA is in VRRP Initialize state, and router RTB is in VRRP Master state
- D . Router RTA is in VRRP Master state, and router RTB is in VRRP Master state.
In the switching network shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are sub VLANs of VLAN10, port Ethernet1/0/3 is a Trunk port, PVID is VLAN1, and all VLANs are allowed to pass; VLAN2~VLAN20 are created on switch SWB, port Ethernet1/0/4 is a Trunk port, PVID is VLAN1, and all VLANs are allowed to pass. Check the Ethernet 1/0/3 port information on SWA, which of the following is the correct display?
