TRUE

FALSE

QUESTION 124
In an MPLS VPN network, which of the following technologies can enable “routing interaction between CE devices and PE devices” to transmit user-side routes? (Multiple choice)

BGP (suitable for scenarios with a large number of routes between CE and PE)

OSPF (suitable for scenarios where CE and PE belong to the same OSPF area)

Static routing (suitable for scenarios with a small number of routes between CE and PE)

Without configuring a routing protocol, routes cannot be exchanged between CE and PE.

Relies solely on MPLS labels, eliminating the need for routing protocols to transmit routes .

QUESTION 125

display bgp vpnv4 peer [neighbor IP] verbose

display bgp vpnv4 all routes

display mpls lsp

display ip routing-table vpn -instance

QUESTION 126
In Huawei’s WAN solution, which of the following technologies can “continue the file transfer from the point of interruption without retransmitting the entire file”?

Transmission encryption technology

Bandwidth adaptive technology

Resumable download technology

Data compression technology

QUESTION 127
In Huawei’s SD-WAN solution, which of the following functions can “monitor the operating status of branch devices (such as link latency and packet loss rate) in real time and generate performance reports”?

Configure version management

Network performance monitoring and reporting

Root Cause Recommendations

Equipment hardware failure alarm

QUESTION 128
In Huawei’s SD-WAN solution, which of the following technologies can “real-time monitoring of the health status of the VPN tunnel between branch devices and headquarters, triggering alarms when abnormalities occur “?

The tunnel condition is manually inspected periodically, and manual alarms are triggered when abnormalities are detected.

Tunnel connectivity detection based on ICMP ping (periodically sending ping packets, triggering an alarm if timeout occurs).

Disable tunnel monitoring function and rely on service interruption to detect anomalies.

Only monitor the physical status of the link, not the logical status of the tunnel.

QUESTION 129
In a wide area network (WAN) BGP protocol deployment, if it is necessary to “set the MED attribute of the route to a specific value when advertising routes to EBGP neighbors, thus affecting the neighbor’s route selection “, which of the following strategies should be configured?

Apply route-policy in the outbound direction of BGP neighbors and set the MED value.

Configure BGP neighbor MD5 authentication

Enable BGP route aggregation, merge routes, and then modify the MED.

Apply a prefix-list to filter routes on the inbound direction of BGP neighbors.

QUESTION 130
In MPLS VPN network planning, which of the following components are the core elements for building an L3VPN (Layer 3 VPN)? (Multiple choice)

PE device (Provider Edge)

CE equipment (Customer Edge)

P equipment (Provider, backbone provider equipment)

VLAN segmentation (only used for Layer 2 isolation, unrelated to Layer 3 VPN)

Physical leased line (can build a Layer 3 VPN without MPLS protocol )

QUESTION 131
(Which of the following functions isnot supportedby AH?)

Anti-replay

Data origin authentication

Data integrity check

Data encryption

QUESTION 132
(Which of the following negotiation modes are supported in IKEv1 negotiation phase 1?)

Normal mode

Main mode

Aggressive mode

Quick mode

QUESTION 133
In Huawei’s SD-WAN solution, for the scenario of ” multi-tenant sharing SD-WAN network”, which of the following technologies can “ensure that the service traffic and configuration of different tenants are completely isolated”?

Tenants share the same configuration template and bandwidth resources.

Create a separate SD-WAN tenant instance (with independent routing and bandwidth) for each tenant.

Filtering tenant traffic only via ACL, without configuring isolation.

All tenants use the same VPN instance, with services differentiated by IP address.

QUESTION 134
In Huawei’s WAN management platform, which of the following functions can achieve “intelligent diagnosis and location of network faults” and improve operation and maintenance efficiency?
(Multiple choice)

Automatic fault correlation analysis (e.g., link fault correlation affecting services and branches)

Fault Root Cause Recommendation (Based on the historical fault database, recommend possible fault causes)

Automatic generation and dispatch of fault handling work orders

Only alarms are displayed; no correlation analysis or root cause recommendations are provided.

Fault work orders need to be created and dispatched manually, which is inefficient .

QUESTION 135
When planning a VXLAN-based virtualized campus network, you need to design underlay, fabric, and overlay networks. Drag the modules on the left to the correct locations on the right. (Token is reusable)

QUESTION 136
In Huawei’s WAN solution, regarding the issue of “intermittent stuttering in VoIP voice services,” which of the following troubleshooting steps should be performed first?

Check if high-priority DSCP tags (such as EF) are configured for VoIP traffic.

Check if the hard drive storage capacity of the branch equipment is sufficient.

Check the bandwidth usage of public internet services.

Check if the routing table of the CE device includes the headquarters network segment.

QUESTION 137
In Huawei’s WAN bandwidth optimization solution, for “cross-regional transmission of office collaboration tool traffic (such as Lark, DingTalk),” which of the following technologies can
“optimize collaborative data transmission and reduce file transfer latency”?

Collaborative data is transmitted directly without optimization.

Collaborative data edge caching (frequently used files are cached at edge nodes) + transmission protocol optimization

Limit the bandwidth of collaboration tools to prioritize other services.

Transmitting collaborative data only during off-peak hours affects real-time performance.

QUESTION 138
(Which of the following is used to implement inter-subnet communication on a VXLAN network and allow access from a VXLAN network to an external non-VXLAN network?)

Layer 3 VXLAN gateway

VLANIF interface

NVE interface

Layer 2 VXLAN gateway

QUESTION 139
In Huawei’s WAN solution, for scenarios where ” intermittent packet loss occurs in the WAN link,” which of the following technologies can “ensure the reliability of data transmission through a retransmission mechanism”?

Ignoring packet loss and not performing any retransmission processing leads to data loss.

TCP-based retransmission mechanism (automatic retransmission of lost data packets)

Reduce the transmission rate to forcibly reduce the probability of packet loss.

Relies solely on link-layer retransmissions, without handling network-layer packet loss.

QUESTION 140
In an MPLS VPN network, which of the following configurations is a necessary condition for “PE devices and CE devices to exchange routes via RIP “?

The PE device enables the RIP protocol under the corresponding VPN instance and is configured with the same RIP version as the CE device.

Configure the RIP protocol on the P device to transmit PE-CE routes.

The MPLS protocol is enabled on the CE device, supporting RIP label forwarding.

Disable BGP VPNv4 address family on the PE device and use only RIP.
