Q129. Regarding BGP MED, which of the following descriptions is correct?

Q133. A lot of overwave techniques have emerged in the process of replacing the IPV4 addresses used in the network with lP6 addresses.

Dual Stack

ISATAP

Q134. As shown in the figure,

RI, R2 establishes an EBGP neighbor and turns on the BFD detection function, the following statement is correct

Detection time for BFD packets for AR2 800ms

R1 Detection time for BFD packets for 1280ms

R1 Detection time for BFD packets The detection time for BFD packets for 660ms

R2 is 600ms

Q135. The following statement about IPv6 Over VXLAN is wrong as ?( Single choice questions).

The tunnel between VXLAN Layer 2 and Layer 3 gateways is an IPv4 network.

IPv6 over VXLAN solves the problem of insufficient IP address resources for end tenants.

IPv6 Over VLANs do not generate ND table entries.

IPv6 over VXLAN means that the Overlay network of the VXLAN is an IPv6 network.

Q136. What are the three ways to send IPv4 messages?

broadcast

Unicast

Multicast

Any broadcast

Q137. What mechanisms or techniques can VRRP combine with to monitor uplink connectivity?

IP-link

BFD

NQA

Interface trace

Q138. Link state information is isolated by default between different IS-IS processes on the same router.

TRUE

FALSE

Q139. As a network administrator, which of the following protocols can I use for network device configuration?

SSH

NETCONF

LLDP

SNMP

Q140. When DLDP detects the presence of a one-way link in the fiber, the default actions of Huawei equipment include: the DLDP state machine migrates to the Disable state, outputs Trap information, and automatically sets the interface to a blocked state.

True

False

Q141. The following description of IGMPv1 and IGMPv2 is correct?( Multiple select).

IGMPv2 message types include member departure packets

IGMPv2 does not support specific group queries

IGMPv1 supports universal group queries

The IGMPv1 message type does not contain members leaving the packet AD

Q142. As shown in the figure, the neighbor relationship between R1 and R2 has just been established, and the database synchronization process between R1 and R2 is correct.

The message sent by R1 to R2 is a PSNP message

R1 sends the packet of R2 as the CSNP packet. The message sent by

R1 to R2 is an LSP packet. The message sent by

R1 to R2 is the Hello message.

Q143. The following description of the CHAP authentication function in the PPP protocol is correct?( Multiple choice questions).

The user name must be configured under the authenticated party interface for CHAP authentication

If the authenticator does not have a username configured, password

can also be configured without the authenticated party interface Using the authentication sequence ID, random number, and key, a Hash value

is calculated using the MD5 algorithm Three message interactions are required for authentication, and only the user name is transmitted on the network without the password

Q144. For Layer 2 VPN technology, the following statement is correct?( Multiple choice questions).

VPLS is a widely used technology in the live network, which can provide transparent transmission of three-layer messages and achieve multi-point access.

The VPLS configuration is complex and the Layer 2 network transmits BUM packets.

BGP EVPN supports features such as tenant isolation, Multi-homing , and broadcast suppression.

BGP EVPN addresses issues such as MAC address drift and multi-tenancy that VPLS cannot support.

Q145. What information does the BGP Open message carry as follows?

BGP Router ID

Route attributes

Local Autonomous System (AS) number

Hold time

Q146. You are now troubleshooting a LAN, and you suspect that the error is due to a mismatch in the work mode.
Which switch interface error indicates that the 10/100/100O IEE gigabit interface operating mode does not match?
( Multiple choice questions).

Alignment error

FCS error

Super Small Frame

Excess Conflict

Lag conflicts

Q147. To achieve an on-machine migration in the BGP EVPN distributed gateway scenario, which of the following messages is required?

Type5

Type4

Typel

Type2

Type3

Q148. When there are multiple redundant links in an IS-IS network, multiple equivalent routes may occur. Regarding equivalent routing within an IS-IS network, which of the following descriptions is wrong?

When the number of equivalent routes present in the networking is greater than the number configured by the command, and these routes have the same priority, the next hop device System IlD large routes are preferred for load sharing

After you configure the equivalent routing priority, when the IS-S device forwards traffic to the destination segment, it will not use load sharing, but forward the traffic to the next hop with the highest priority

For each of the equivalent routes, you can assign a priority, with the highest priority routes preferred and the rest as backup routes

If load sharing is configured, traffic is evenly distributed across each link

Q149. Auto-negotiate mode is to obtain the maximum interface rate and operating mode, the network administrator configures all Ethernet interface rates of a working switch to 10OMbps, and the operating mode is configured as Full-duplex, when a network card is configured After the auto-negotiate workstation is connected to the switch, the negotiation result is that the interface rate is 10OMbps and the working mode is half-duplex, which of the following explanations is the most reasonable for this phenomenon?

The problem is on the workstation’s NIC, mostly due to the aging of the NIC driver on the workstation , which causes the workstation NIC to learn the interface rate and operating mode configured on the switch

Port rate negotiation is negotiated through the initial port sending FLP , and the operating mode is not negotiated through FLP

STP initializes the port into the blocking state, causing auto-negotiation to fail, so the port should be configured as an edge port

At higher port rates and operating modes, the workstation’s network interface card cannot be configured as auto-negotiate

Auto-negotiation is not configured on the switch, resulting in the switch not being able to send FLP messages to the workstation, causing the workstation to set its own operating mode to Half-duple

Q150. The Layer 3 logical interface on XLAN L3 Gateway that enables communication between different VXLAN virtual networks is ?

Layer 2 sub-interface

NVE interface

VBDIF interface

VLANIF interface

Q151. The following statement about IPSec VPN is correct ?qo

Two routers establish an IPSec VPN in brutal mode, so that the two devices can interact with a minimum of 4 messages to establish a tunnel.

Brutal mode can support NAT traversal, while main mode does not support NAT traversal.

The two routers can establish OSPF neighbor relations and exchange intranet routes through the IPSec VPN tunnel

The two routers establish IPSecVPN in main mode, and from the 5th packet (included), the payload’s data will be encrypted.
