Question 81

The topology is shown in the figure, and the STP calculation is performed. The correct result is:

A.Since the root bridge ID, root path cost, designated bridge ID, and designated port are the same, the root port of SWD cannot be determined

B.SWD needs to determine the root port by comparing the ID of the port that receives the configuration BPDU

C.If the bridge priority of SWD is set to 0, port E0/2 of SWD will only receive configuration BPDUs and not send configuration BPDUs

D.If the bridge priority of SWD is set to 0, SWD will become the root bridge, and ports E0/1 and E0/2 are designated ports

Question 82

In the switching network as shown in the figure, VLAN10 is set to Isolate-userW, VLAN2 and VLAN3 are the Secondary VLAN of VLAN 10 on the switch SWA; VLAN2 VLAN20 is created on the switch SWB, and VLAN20 is set to Isolate-user-vlan, and VLAN4 is After setting the IP address of each device as shown in the figure for the Secondary VLAN of VLAN20, check the MAC address table on the SWB to determine that SWA belongs to

A.VLAN4

B.VLAN 10

C.VLAN2

D.VLAN20

E.VLAN3

F.VLAN 1

Question 83

The following are core layer functions (choose one or more)

A.High-speed packet switching

B.Possess a large number of interfaces for connecting with end user computers

C.Necessary routing strategy

D.Access security control

Question 84

In the switching network as shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is the Secondary VLAN of VLAN20. After setting the IP address of each device as shown in the figure, the following statement is correct (choose one or more)

A.The packet of PCA enters from the GigabitEther1/0/1 port of SWA, and does not carry the VLAN tag after exiting from the GigabitEther1/0/3 port

B.The PCA packet comes out of the GigabitEthem1/0/3 port of SWA and enters the GigabitEthe1/0/3 port of SWB, and the VLAN Tag carried is VLAN2

C.When SWB accesses PCA, the VLAN tag carried by GigabitEthem1/0/4 of SWB is VLAN 1

D.SWB packets enter from SWA's GigabitEthem1/0/3 port, and after exiting from GigabitEthem1/0/1 port, the VLANTag carried is VLAN2

Question 85

Regarding the working mode of VoiceVLAN, the correct statement is

A.In manual mode, you need to manually add the IP phone to the Voice VLAN

B.In manual mode, the system will not issue ACLs to the port

C.In automatic mode, the system will recognize the packet sent by the IP Phone, if the match is a voice packet, the port connected to the IP Phone will be added to the Voice VLAN

D.The working mode of VoiceVLAN includes automatic and manual
