As shown in the figure, initially link 2 is not connected, and the switches do not enable STP. PCB can send data to PCA. If link 1 fails at this time, the maintenance personnel connect link 2. Which of the following is the correct statement about the recovery process of the data transmission service from PCB to PCA is (assuming that PCA will not actively send data) (Multiple choice)

• A.The default time for PCB to PCA service recovery is 300 seconds
• B.SWB's EO/1 interface can immediately enter the forwarding state
• C.The default time for PCB to PCA service recovery is 30 seconds
• D.SWC can immediately forward the data from PCB to PCA to SWB

In the RADIUS message received from the RADIUS server, it is found that the value of the Code field in the message structure is 3, then which of the following is correct? (Multiple choice)

• A.This message is a RADIUS authentication message
• B.The Code field determines the RADIUS message type
• C.The Code field describes the RADIUS attribute type
• D.This message is a RADIUS accounting message

In the switching network shown in the figure, VLAN 10 is set as lsolate-user-vlan on switch SWA, and VLAN 2 and VLAN 3 are set as Secondary VLAN of VLAN 10; VLAN 20 is created on switch SWB, and VLAN 20 is set as lsolate-user-vlan, and VLAN 4 is set as Secondary VLA of VLAN 20. 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. What is the source MAC address of the ARP request message forwarded by the switch to PCB?

• A.0000.0000.0000
• B.0011.1111.1111
• C.00E0.FC00.0010
• D.00E0.FC00.0020

NTP provides a variety of working modes to adapt to different application scenarios. Which of the following descriptions of NTP working modes is correct? (Multiple choice)

• A.In peer mode, active peers and passive peers can synchronize clocks with each other
• B.The client/server mode is suitable for situations where the address of the clock server is known, and can appropriately increase the possibility of clock synchronization
• C.Multicast mode is suitable for situations where the IP address of the server or peer is uncertain, simplifying deployment
• D.Broadcast mode is suitable for point-to-multipoint network applications, improving deployment and operation efficiency
