NO.101 In the switching network as shown in the figure, VLAN10 is set as Isolate-user-vlan on the switch SWA, VLAN2 and VLAN3 are the Secondary VLAN of VLAN 10; VLAN2? VLAN20 is created on the 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, which of the following statements is correct (choose one or more)

The PCA packet enters from the GigabitEthe1/0/1 port of SWA, and the VLAN Tag carried after it exits the GigabitEthem1/0/3 port is VLAN 10

The PCA packet comes out of the GigabitEthem1/0/3 port of SWA and enters the GigabitEthem1/0/4 port of SWB without VLAN tag

When SWB accesses PCA, after the packet comes out of the GigabitEthem1/0/4 port of SWB, the VLAN Tag carried is VLAN20

SWB packets from GigabitEthernet1/0/3 of SWA come out of GigabitEthem1/0/1 without VLAN

NO.102 Regarding the role and status of the STP port, the following statements are correct:

The designated port will enter the Forwarding state after two ForwardDelay durations

Only the designated port will eventually be in the Forwardig state

Only the Alternate port will be in the Blocking state

The port with the role of Alternate will not go through the Listening state and the Learning state

NO.103 Regarding the basic concepts of MSTP, the correct statement is

IST is a fragment of CIST in the MST region, and the root of IST is the bridge with the highest priority in the MST region

The root of IST is the bridge closest to the total root in IST

One MST region can contain multiple MSTI instances, and different MST regions can contain different MSTI instances

One MSTI instance can map multiple VLANs, and the VLAN mapping relationship in different MST regions can be different

NO.104 A loop in the LAN may cause it.

Broadcast storm

Port rate changes

Port duplex mode changes

MAC address learning error

NO.105 When the switch running MSTP and the switch running RSTP work together, the statement is correct.

The RSTP switch regards the MST domain as a logical switch, and the bridge ID is the ID of the switch directly connected to the RSTP switch in the MST domain

The MSTP switch will treat the RSTP switch as an MSTP domain composed of a single switch

MSTP switch and RSTP switch can belong to the same MST domain

MSTP switch will parse RSTBPDU into MST BPDU, where IRPC is 0

NO.113 Regarding the relationship between SuperVLAN and Sub VLAN, the following description is correct

SuperVLAN is equivalent to aggregating Sub VLANs so that all Sub VLANs share the same Layer 3 interface

SuperVLAN only establishes Layer 3 interfaces, responsible for Layer 3 forwarding of Sub VLAN

Sub VLAN only contains physical ports, and the internal host uses the address of the Super VLAN interface as the gateway

Although physical ports cannot be included in SuperVLAN configuration, after the mapping relationship between Super VLAN and Sub VLAN is established, the physical ports included in SubVLAN belong to Super VLAN
