QUESTION 312
What are the ways to divide VLANs in Huawei switches? ( Multi-select)

Subnetting based on IP.

Division based on QoS

Partitioning based on port

Division based on protocol

Division based on MAC address.

QUESTION 313
View the IGMP configuration of the interface on the router RTA as follows, and the information about the operation of the RTA is incorrect

The packet interval for a particular group query is 60 seconds

The interface IP address is 1921681.1

The maximum response time for query messages is 10 seconds

The IGMP protocol version is 2

QUESTION 314
The following statement about is the ISIS protocol LSP message is correct

LSP fast diffusion feature, first diffuse less than the specified number of LSPs, to speed up the synchronization process of LSDB

By configuring an LSP-generated smart timer, the timer automatically adjusts the delay time based on the frequency of changes in routing information

When the link status information increases, the message length of the LSP can be increased so that each LSP can carry more information.

Reducing the minimum time interval for sending LSPs per port can speed up the diffusion of LSPs.

QUESTION 315
When deploying BGP/MPLS IPVPN, OSPF’s VPN route tag is not present
The extended properties of MP-BGP are passed only locally, only locally, and only meaningful on routers that receive MP-BGP routes and generate OSPF LSAs.

TRUE

FALSE

QUESTION 316
What is the relationship between CIR, BC and TC? (single select)

CIR=TC/BC

CIR=BE/TC

TC=CIR/BC

TC=BC/CIR

QUESTION 317
In EPIM-SM, the following description of the PIM Join message is correct?

PIM Join messages are sent every 3 minutes, and status

PIM Join messages for the multicast tree are only sent when the multicast tree is first established

The PIM Join message is sent every 60 seconds to refresh the status of the upstream router mroute for the multicast tree

The upstream router sends a PIM Join acknowledgment in response to each PIM Join message received from the downstream router

QUESTION 318
Is the following statement about VLAN aggregation correct?

Sub-VLAN is used to isolate broadcast domains

A Super VLAN can contain one or more Sub-VLANs

The super Sub-VLAN contains a physical interface that can establish a Layer 3 VLANIF interface

Sub-VLAN contains a physical interface that can establish a Layer 3 VLANIF interface

QUESTION 319
In a VXLAN network, traffic is connected to the VXLAN network, and it can also be used to communicate with the same subnet within the same XLAN network

NVE interface

VXVAN L2 Gateway

VXLAN L3 Gateway

VLANIF interface

QUESTION 320
In PIM-SM, the description of RP is incorrectly ?

All members of the group and the multicast sources that send multicast data to the group converge to the unique RP

The initial multicast streams for all groups in the shared tree are forwarded to the receiver via RP

An RP can serve multiple multicast groups at the same time, a multicast group can correspond to multiple RPs

RPs can be responsible for the forwarding of several or all multicast groups, and there can be an RP in the network

QUESTION 321
IS-IS supports the processing and computation of IPv6 routes by adding ATLPs to carry IPv6 addresses and reachability information.

TRUE

FALSE

QUESTION 322
The following description of the characteristics of cross-domain VN-Optionc is correct?

A maximum of two layers of tags need to be used in the message forwarding process.

VPMV4 routes are not saved on the ASBR, and VPNv routes are not advertised to each other.

VPN routes are exchanged directly between the ingress PE and egress PE and do not require an intermediate device to secure a circular VPN route.

Cross-domain VN-Optionc, which is not suitable for use when spanning multiple AS.

QUESTION 323
In the use of the CP protocol, the following description is correct?

The Eth-Trunk interface can be avoided by frequent oscillation interfaceeth-trunkllacppreemptenablelacppreemptdelaydelay-time by following command

Source A address can be configured for load sharing in an enabled link aggregation group with the following command: interface eth-trunk 110ad-balance src-dst-ip

A member interface can be removed from an enabled link aggregation group with the following command: interface GigabitEthernet0/0/1 shutdown interface GigabitEthernet0/0/1 undo eth-trunk 1 interfaceGigabitEthernet0/0/1undoshutdown

The member interface can be joined in the link aggregation group by enabling the following command: interface GigabitEthernet0/0/1 shutdown interface GigabitEthernet0/0/1 trunkport

QUESTION 324
Use ping-ax-cY-sZ-vpn-instance M 105162, which has the meaning of

IcMP request for the ping, message size Z (without IP and ICMP headers)

The source IP address of the ping packet is X

The ping belongs to the VPN instance M

The ping sends Y ICMP requests

QUESTION 325
In the description of the MAC address spoofing attack, the error is ? Radio

Mac address spoofing attacks cause the switch to learn the wrong mapping of Mac addresses to IP addresses

A MAC address spoofing attack causes the data that the switch is sending to the correct destination to be sent to the attacker

MAC address spoofing attacks primarily exploit the switch Mac address learning mechanism

An attacker can perform a MAC address spoofing attack by sending a forged source Mac address data frame to the switch

QUESTION 326
IPv6 introduces the Solicited-Node address, which is described correctly below (multiple choice)

This is a specific address that is used for resolution in ARPv6 The MAC address.

The Solicited-Node address on the router interface is automatically generated and can have multiple.

If the Solicited-Node address is not configured , the router automatically generates one on each interface.

IPv6 introduced the Solicited-Node address to support IPv6 multicast.

QUESTION 327
What is the security level for untrust zones in the USG Series firewalls? ( Radio).

QUESTION 328
OSPF fast convergence is an extended feature to improve the convergence speed of routing, in which PRC works by speeding up routing computation by performing path calculations only on the affected nodes when the network topology changes.

TRUE

FALSE

QUESTION 329
Regarding the FTP protocol, which of the descriptions below is correct?

In FTP Passive mode, the client completes the initialization of the TCP session for control and data

In FTP Active mode, the server tells the client which port it expects to send data on by commanding “PORT”

FTP always uses a TCP session to transmit control information and data information

FTP always uses TCP port 20 to establish a data session, and ICP port 21 to establish control will always use

FTP TCP port 21 to establish a data session, TCP port 20 to establish a control session

QUESTION 330
Traditional BGP-4 can only manage IP4 unicast routing information, and MP-BGP extends BGP-4 to provide support for multiple network layer protocols. Among them, MP-BGP’s support feature for IPv6 unicast networks is called BGP4+, BGP4+ via NextHop The route next hop address information is carried by the attribute.

TRUE

FALSE

QUESTION 331
ISIS does not send CSNP packets under the P2P network type during the neighbor establishment process.

True

False

QUESTION 332
Router HW1 and Router HW2 connect Network A and Network B, respectively. As shown in the figure below, if you want to set up an IPsec VPN between router HWI and router HW. (single selection).

rule permit ip source 1921681.10 destination 19

rule permit ip source 101.1.0000255 destination 19

rule permit ip source 101.1.0000255 destination 101.

rule permit ip source 1921681.10 destination 101.

rule permit ip source 101.20 000255 destination 101.1.0000255

QUESTION 333
Regarding MP-BGP, the following description is wrong?

Radio MP-BGP needs to assign a private label to the VPNv4 route

PE and CE are routed through BGP interaction, you need to create a BGP process on ce for each VPN instance

The message type and VPNv4 routing publishing policy for MP-BGP are the same as for BGP-4

MP-BGP advertises VPNv4 through two attributes, MP_REACH_NLRI and MP_UNREACH_NLRI Route
