NO.132 In the network shown in the figure, the corresponding configuration is completed on the switch SWA, and the switch SWA and each PC have learned the corresponding ARP table entry. When PCA accesses the PCB, an ICMP request message is sent, and the destination IP address of the message is

10.1.1.1

10.1.1.2

20.1.1.1

20.1.1.2

NO.133 SOA-based network architecture divides the enterprise IT system into which of the following levels-(choose one or more)

Application layer

Business layer

Network layer

Service layer

NO.134 If customers prefer to use TACACS+ protocol instead of RADUS to complete user access authentication, this may be because

TACACS+ protocol encrypts all the body of the message with high security

TACACS+ protocol uses TCP reliable transmission

The TACACS+ protocol message is simple, which can be combined with authentication and authorization, or separated easily

TACACS+ adopts UDP protocol, high network transmission efficiency

NO.135 Which types of mirroring groups supported by H3C S series switches include the following

Local

Remote-source

Remote-destination

Remode

NO.136 Regarding the port filtering mode of VoiceVLAN, the correct statement is

The port filtering mode of VoiceVLAN can be divided into security mode and normal mode.

In normal mode, the device will no longer check the MAC address of the message after the port enters the VoiceVLAN.

In the safe mode, the device will perform a MAC matching check on each packet that will enter the VoiceVLAN for transmission

By default, VoiceVLAN works in normal mode

NO.137 Before configuring Layer 3 multicast, the first configuration that needs to be done is

Enter IGMP view

SB sets the IGMpi protocol version

Configure PIM protocol

Enable multicast globally through the multicastrouting-enable command

NO.138 Regarding the compatibility configuration of MSTP, there are correct statements

The MSTP compatible working mode of the port can be configured through the command stpcompliance. The parameter auto means that the port only sends and receives MSTP messages that are compatible with non-standard formats.

The port of the H3C switch can be configured to automatically recognize the format of the MSTP message and determine the format of the message sent according to the recognition result

If the port identification/sending MSTP message mode is configured as dotls, the port will only send and receive standard format MSTP messages

If the MSTP message format received by the port is inconsistent with the configured message format, the port will become the designated port and the port status will remain in the Discarding state to prevent loops.

NO.139 The SSH protocol is widely used as a secure remote login protocol. What is correct about SSH is _______

SSH uses additional encryption technology to ensure login security

SSH uses TCP port 22 to transmit data and port 23 to establish a connection

SSH can also provide a secure transmission channel for FTP

SSH and Secure Shell can use DES authentication to ensure data security

NO.140 In the switching network as shown in the figure, VLAN10 is set as Super VLAN on the switch SWA, VLAN2 and VLAN3 are Sub VLANs of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to be judged by setting the IP address of each device as shown in the figure (choose one or more)

SWB can communicate with PCA

SWB can communicate with PCB

SWB can communicate with PCC

SWB can communicate with SWA

None of the above answers

NO.141 Which statement about the STP protocol is correct?

STP is used to construct the shortest path between two nodes in the LAN

STP is used to eliminate data link layer loops in LAN

STP is mainly used in token ring networks

When the active link fails, STP can activate the redundant link and restore network connectivity

NO.142 In the PIM-DM network as shown in the figure, part of the unicast routing table of routers RT1 and RT2 is as follows:
<RT1>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.1.0/24xxxxP1-1 C1-110.1.1.1POI11
1.1.0.0/16xxxxP1-2 C1-210.1.1.1Port1
<RT2>display ip routing-table
Routing Tables: Public

If P1-1> P2-2,

If P1-2>P2-2,

If P1-1 = P2-2,

If P1-2 = P2-2,

If P1-1= P2-2,

If P1-2 = P2-2,

NO.143 For the following configuration commands:
[H3C] ntp-service refclock-master 127.127.1.1 6
Understanding, which is correct

This command can be successfully configured on all H3C series switches

This command configures the local clock as the reference clock of the system

The device successfully configured with this command has a clock accuracy of 6 in stratum

The device successfully configured with this command can act as a clock server to provide external clock synchronization services

NO.144 After executing the displayinterface Ethernet 1/0/1 command on the switch SWA, the output information is as follows:
[SWA]display interface Ethernet 1/0/1
Ethernetl/0/1 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
It can be judged from the above output

Port Ethernet1/0/1 is a Trunk port, allowing all VLAN data to pass through

Data frames with VLAN1 tags will be stripped of tags when they leave port Ethernet1/0/1

Data frames with VLAN20 tags can be forwarded from port Ethernet1/0/1

Data frames with VLAN10 tags will not be discarded when entering port Ethernet1/0/1

NO.145 What is correct about the interoperability between Sub VLANs in SuperVLAN technology?

Host IP addresses in different SubVLANs belong to the same network segment, and they can communicate directly with each other through Layer 2 forwarding

Host IP addresses in different SubVLANs belong to the same network segment, but due to the isolation effect of Sub VLANs, it is impossible to achieve intercommunication between Sub VLANs.

The hosts in different SubVLANs are isolated at the second layer, and the third layer can communicate with each other through the ordinary proxy ARP technology of the Super VLAN interface

Layer 2 isolation between hosts in different SubVLANs, Layer 3 can communicate with each other through the local proxy ARP technology of the Super VLAN interface

NO.146 In order to achieve efficient network management, what servers do we often need to deploy in large campus networks?

Network management server

FTP server

Telnet server

Log server

NTP server

NO.147 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

NO.148 Regarding the spanning tree port overhead configuration of H3C switches, the following statements are correct:

H3C switches support three port cost standards, dot1d-1998, dot11, and legacy. The port cost standards to be followed can be switched through the command stp pathcost-standard

The default spanning tree port cost standard for H3C switches is legacy

By default, the larger the port cost, the smaller the port bandwidth

If switches of different manufacturers are interconnected, each switch should be configured to follow the same port cost standard as much as possible, otherwise it may cause the spanning tree calculation result to deviate from the original intention of the network design

NO.149 In the switching network as shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are Sub VLAN of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allow all VLANs by setting the IP address of each device as shown in the figure, you can judge_

PCA can communicate with PCB

PCA can communicate with PCC

PCA can communicate with SWA

PCA can communicate with SWB

None of the above answers
