The figure shows the networking of Smart Link and Monitor Link cascade. The Smart Link group on switch SWH is used as the uplink port of the Monitor Link group on switch SWH, and the peer port of the downlink port of the Monitor Link group is the master port of the Smart Link group on switch SWJ. The uplink SWD and SWE ports of switch SWH are the ports of the Smart Link group. What can we learn from the above information?
- A . If the link of switch SWH to switch SWD is down, the master port of switch SWJ Smart Link group will switch to the slave port.
- B . If the link of switch SWH to switch SWE is down, the primary port of the Smart Link group of switch SWJ will switch to the secondary port.
- C . If the links of the upstream switches SWD and SWE of switch SWH are both in Down state, the primary port of the Smart Link group of switch SWJ will be switched to the secondary port.
- D . The Smart Link group status of switch SWJ has nothing to do with switch SWH

- B . 99.99%
- C . 99.999%
- D . 99.9999%
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 with PVID of VLAN1, allowing all VLANs to pass through. VLAN2~VLAN20 are created on switch SWB, port Ethernet1/0/4 is a Trunk port with PVID of VLAN1, allowing all VLANs to pass through. After setting the IP addresses of each device as shown in the figure, check the MAC address table on SWA, and you can determine that PCC belongs to?
- A . VLAN 1
- B . VLAN 2
- C . VLAN 3
- D . VLAN 10
After executing the display interface Ethernet 1/0/1 command on the switch SWA, the output information is as follows: From the above output, what can be inferred from the above output?
[SWA] display interface Ethernet 1/0/2
Ethernet1/0/2 current state: UP
………….
PVID: 10
Mdi type: auto
Link delay is 0 (sec)
Port link-type: trunk
VLAN passing: 1 (default vlan), 10
VLAN permitted: 1 (default vlan), 2-4094
Trunk port encapsulation: IEEE 802.1q
Port priority: 0
- A . The data frame with VLAN10 tag will not be stripped when it leaves port Ethernet 1/0/1.
- B . The data frame with VLAN10 tag will be stripped of the tag when it leaves port Ethernet 1/0/1
- C . Data frames with VLAN1 tags will be discarded when they enter port Ethernet 1/0/1
- D . The data frame with VLAN10 tag is discarded when it enters port Ethernet 1/0/1
A customer wants to deploy 802.1X in the LAN to improve access security. At the same time, the customer wants to use the port security feature to temporarily close the port for 5 minutes to prevent illegal users from accessing the network. Which of the following features can be used to achieve this?
- A . NeedToKnow feature
- B . InstrusionProtection Features
- C . Trap Features
- D . ntk temporary characteristics
Which of the following statements is correct regarding the configuration of the spanning tree protection mechanism?
- A . BPDU protection needs to be configured in the port view designated as the edge port.
- B . The root bridge protection command will only play a protective role when it is configured on the root bridge in the network.
- C . The loop protection command needs to be configured on each port on the physical loop.
- D . After configuring the TC protection threshold, if the number of TC messages received by the device within the default 10 seconds exceeds the threshold, the device will no longer delete the address table entry within these 10 seconds.
The figure shows the networking application of RRPP. The switches SWA, SWB, SWC, and SWD in the customer LAN form the main ring 1 of the RRPP ring. The switches SWB, SWC, and SWE form the sub-ring 2. The switches SWB, SWC, and sWF form the sub-ring 3. If the switch SWE is the master node of the sub-ring 2 and SWF is the master node of the sub-ring 3, What can we learn from the above information?
- A . It is not possible to add sub-ring 2 and sub-ring 3 to the same ring group.
- B . If sub-ring 2 and sub-ring 3 are added to the same ring group, the edge nodes and auxiliary edge nodes of sub-ring 2 and sub-ring 3 in the ring group can be different
- C . If sub-ring 2 and sub-ring 3 are added to the same ring group, the ring groups should be configured on the switches SWB, SWC, SWE, and SWF respectively and the configurations should be consistent.
- D . If sub-ring 2 and sub-ring 3 are added to the same ring group, the primary ring links corresponding to the edge nodes and auxiliary edge nodes of sub-ring 2 and sub-ring 3 in the ring group should be consistent.
If port-based VLAN, MAC address-based VLAN, protocol-based VLAN and IP subnet-based VLAN are enabled on a port of the switch, by default, the VLANs will be matched in order?
- A . Port VLAN MACVLAN Protocol VLAN IP Subnet VLAN
- B . Port VLAN IP Subnet VLAN Port VLAN MAC VLAN
- C . MACVLAN Port VLAN Protocol VLAN Subnet VLAN
- D . MACVLAN Subnet VLAN Protocol VLAN Port VLAN
Two routers are connected together through a LAN to form a VRRP backup group. The configuration on each interface is as follows:
