[RTA-Ethernet0/0]interface ethernet 0/0.2
[RTA-Ethernet0/0.2]ip address 20.20.20.1 255.255.255.0
[RTA-Ethernet0/0.2]vlan-type dotlq vid 2
[RTA-Ethernet0/0.2]interface ethernet 0/0.3
[RTA-Ethernet0/0.3]ip address 30.30.30.1 255.255.255.0
[RTA-Ethernet0/0.3]vlan-type dotlq vid 3
After completing the corresponding configuration on the switch SWA, PCA, PCB and PCC can ping their own gateway. The configuration of the switch SWA port Ethernet1/0/4 should be (choose one or more)

interfaceEthernet 1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all

interfaceEthernet1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all port trunk pvid vlan 2

interface Ethernet1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all port trunk pvid vlan 3

interface Ethernet 1/0/4 port link-mode bridge port link-type trunk port trunk permit vlan all port trunk pvid vlan 10

Q138. In the networking model shown in the figure, if Accoing is received on RADIUsClient, the following statement may be correct.

The message is sent by Host

The message is sent by RADIUS Server

The message is a stop-accounting response message

This message is a start-accounting response message

Q139. In the switching network as shown in the figure, all three switches only have the default VLAN1, the interconnection ports of the three switches are trunks, and all VLANs are allowed to pass, and the three switches have the global and port GVRP functions enabled. VLAN 10 is created on the switch SWA, VLAN 20 is created on the switch SWC, and the GVRP registration mode of the Ethernet 1/0/1 port is set to Fixed on the switch SWA, and the display vlan command is executed on the SWB to view the VLAN existing on VLASWB ( Select one or more)

VLAN1

VLAN 10

VLAN20

Q140. In the switching network as shown in the figure, set VLAN10 as Isolate-userW, VLAN2 and VLAN3 as the Secondary VLAN of VLAN 10 on the switch SWA; create VLAN2-VLAN20 on the switch SWB, and set VLAN20 as Isolate-user-vlan, VLAN4 For the Secondary VLA 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)

PCA packets enter from the GigabitEthem 1/0/1 port of SWA, and the VLAN Tag VLAN 1 after exiting from the GigabitEthem 1/0/3 port

The PCA packet comes out of the GigabitEthem1/0/3 port of the SWA, and enters the GigabitEthem1/0/4 port of the SWB, and the VLAN tag carried is VLAN 10

When SWB accesses PCA, the packet from SWB GigabitEth1/0/4 without VLAN Tag

SWB packets enter from SWA’s GigabitEthem1/0/3 port, and after exiting from GigabitEthem1/0/1 port i, the VLAN Tag carried is VLAN 10

Q141. Regarding the MSTP BPDU format, the correct statement is

IST calculation only requires the value in the MST proprietary field

The MST configuration ID field is used to determine whether the switch belongs to the same MST region

MSTI configuration message is used for MSTI spanning tree calculation

The number of MSTI configuration messages is determined by the number of VLANs

Q142. In the PIM-DM networking, regarding the process of SPT formation (without considering the state refresh mechanism), the correct description is:

After the process of flooding and pruning, an SPT between the multicast source and the multicast receiver is formed

The diffusion-pruning process is carried out periodically

The pruned interface no longer sends multicast packets downstream

As long as the network topology and unicast routing information remain unchanged, the formed SPT tree will not change

Q143. What is correct about IGMP Snooping?

Both IGMP & IGMP Snooping can be configured in the same VLAN

Port quick leave means that when the switch leaves the IGMP Leave message, it directly deletes the port from the outgoing port list of the corresponding forwarding entry

The unknown multicast group dropping function can be enabled on the switch. When the switch receives unknown multicast data packets, it will only forward to its router port and not broadcast in the VLAN.

Using the iIGMP Snooping function on the Layer 2 device can establish and maintain multicast forwarding entries at the data link layer, so that multicast data can be forwarded normally at the data link layer

Q144. As shown in the network topology, if STP is enabled on SWA and SWD, the statement about the state change of SWA and SWD port is correct.

Both E0/1 of SWA and E0/1 of SWD need to pass the ForwardDelay of Listening and Learning states to enter the Forwarding state.

The E0/1 port of SWD undergoes a port role change in the Listening state, from a designated port to a root port

The E0/2 port of SWD changes its role in the Learning state, and changes from the designated port to Altenet

If the bridge priority of SWD is modified to 0, port E0/2 of SWA will directly enter the Blocking state, without the delay of Forward Delay

Q145. Regarding the generation of TCNBPDU, the following statements are correct

STP-enabled non-root bridge switch If a port is connected to a PC, when the port enters the Forwarding switch, it will not produce TCN BPDU

If the designated port link of a switch in the network is broken, the switch must generate TCNBPDU

If the alternate port of a switch in the network is down, the switch will not generate TCN BPDUs

When a port of the switch is selected as the designated port or root port, the switch will immediately send TCNBPDU

Q146. What is the correct statement about the MSTP calculation process?

The master port of the MST region must be located on the IST region root

Each MST region will have a Master port

In the actual calculation process, the calculation of CST and IST is not in sequence, but is completed synchronously

In the actual calculation process, the CIST must be calculated first, and then the MSTI calculation

Q147. 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

Q148. Among the following PIMV2 messages, the destination address is a multicast address.

Hello

Join

Prune

Assert

Graft

Graft-ACK

Q149. Which of the following multicast group management protocols can support the SSM model-(choose one or more)

IGMPvl

IGMPV2

IGMPV3
