1. Which of the following statements about the forwarding plane of traditional networks and SDN networks are correct? (Multiple choice)

A) Multicast packets in the SDN network enter the VXLAN tunnel for unicast forwarding
B) Multicast messages in traditional networks are forwarded via IGMP, PIM or flooding
C) The tenants of traditional networks and SDN networks communicate with each other through routing.
D) The SDN network needs to decapsulate the VXLAN message when going out of the network and send it to the VLAN network

2. XYZ company's two LANs are located in different regions and are interconnected through the operator's network. The network topology is shown in the figure. Switches SWC and SWD are the company's network edge devices, and switches SWA and SWB are the operator's network edge devices.
Hosts PCA and PCB are located in VLAN2 of the company's network. The operator network assigns VLAN tags to XYZ company's data packets passing through it. Under normal circumstances, the port that needs to enable the Qinq function is? (Multiple choice)

A) Ethernet 1/o/2 of switch SWA
B) Ethernet 1/0/1 of switch SWA
C) Ethernet1/0/1 of switch SWB
D) Ethernet 1/0/2 of switch SWB

3. In the switching network shown in the figure, set VLAN10 as Isolate-user-vlan on switch SWA, and VLAN2 and VLAN3 as Secondary VLAN of VLAN 10; create VLAN4 and VLAN20 on switch SWB, and set VLAN20 as Isolate-user-vlan, and VLAN4 as Secondary VLAN of VLAN20. 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 which of the following?

A) VLAN 10
B) VLAN 1
C) VLAN 4
D) VLAN 3
E) VLAN 20
F) VLAN 2

4. After executing the display interface Ethernet 1/0/2 command on the switch SWA, the output information is as follows:
[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
what can we learn from the above information? (Multiple choice)

A) The current switch has only VLAN1 and VLAN10.
B) Port Ethernet1/0/2 only allows data from VLAN 1 and VLAN 10 to pass through.
C) The data frame with VLAN1 tag will not be stripped when it leaves port Ethernet1/0/2
D) Data frames with VLAN 20 tags will be discarded when they enter port Ethernet 1/0/2

5. In SDN networks, which of the following problems exist in the traditional network security deployment method? (Multiple choice)

A) Security equipment capabilities cannot be shared among multiple services
B) Data packets need to be classified multiple times, which is inefficient.
C) In Overlay networking, network devices need to detect inner messages through Overlay encapsulation
D) The coupling between network devices is large and the topology is seriously dependent.
