Direct connection mode + tunnel forwarding

Side-by-side mode + direct forwarding

Side-by-side mode + tunnel forwarding

QUESTION 118
is the main application scenario of Wi-Fi 6 CPE ?

Hotel scene

Park office scene

Industrial manufacturing scenarios

Stadium scene

QUESTION 119
Huawei WLAN products can achieve three-layer roaming within AC

Correct

Error

QUESTION 120
When planning sites for an EVPN interconnection solution, in addition to planning site roles as described in the network model, it’s also necessary to plan the site WAN model from the perspective of network reliability. Reliability design primarily involves the following two aspects: Redundancy design for network egress devices and redundant design for network egress links. There are many possible combinations of redundant designs. For this purpose, the system provides several default link templates. Which ones are they?

Single-gateway MPLS link

Single gateway hybrid dual link

Single-gateway Internet link

Dual-gateway hybrid single link

QUESTION 121
Which of the following channels does Huawei’s SD-WAN solution use to achieve flexible networking?

Control Channel

Protocol Channel

Management Channel

Data Channel

QUESTION 122
For WLAN In VRRP hot standby, what technology is used for data synchronization between ACs?

HSB

CAPWAP

HRP

VRRP

QUESTION 123
What protocol is WiFi6?

802.11n

802.11b

802.11ax

802.11ac

QUESTION 124
In the VLAN design of a campus network, which of the following considerations is correct?

When planning VLANs, it is recommended to assign VLAN numbers continuously to ensure the rational use of VLAN resources.

Typically, a Layer 2 switch uses the VLANIF interface address as the management address. It is recommended that each Layer 2 switch be assigned a separate VLAN to reduce interference.

VLAN division needs to distinguish between service VLAN, management VLAN and interconnection VLAN.

It is recommended to reserve a certain number of VLANs to facilitate subsequent expansion.

QUESTION 125
Which of the following descriptions about remote modules is correct?

Topology discovery can be automatically completed through the XLDP protocol

Support plug and play

Support POE power supply

Only supports optical fiber hybrid cables

QUESTION 126
Which statement is correct regarding the classification of roaming?

Sometimes, a network situation arises where two subnets share the same VLAN ID, but belong to different subnets. To prevent the system from misidentifying inter-subnet roaming as Layer 2 roaming based solely on the VLAN ID, the roaming domain is used to determine whether the devices are within the same subnet. Only when the VLANs and roaming domains are the same does Layer 2 roaming occur; otherwise, it is Layer 3 roaming.

Layer 2 roaming: When a user moves between APs, the terminal signal connects from the old AP to the new AP, which is roaming. The service VLAN of the AP remains unchanged before and after roaming, and the corresponding gateway remains unchanged.

Layer 3 roaming: The service VLANs of the SSIDs before and after roaming are different. The service networks provided by the APs are different Layer 3 networks, corresponding to different gateways. In this case, to maintain the unchanged IP address of the roaming user, it is necessary to migrate the user traffic back to the API of the initial access network segment to achieve cross-VLAN roaming.

QUESTION 127
Huawei SD-WAN mainly establishes data channels through GRE or GRE Over IPsec.

Correct

Error

QUESTION 128
What are the ways for sites to access the Internet in Huawei’s SD-WAN solution?

Default local Internet access + optional centralized Internet access

Centralized Internet Access

Default centralized Internet access + local Internet access for designated applications

Local Internet access

QUESTION 129
In the SD-WAN framework, which statement about the controller’s remote disaster recovery solution is incorrect?

The controller uses a unified domain name or IP address for northbound and southbound traffic. Tenants and devices access the active controller cluster through the unified domain name or IP address. After a master/slave switchover, traffic automatically switches to the new active cluster.

The controller’s primary and backup clusters run simultaneously. Only the primary cluster can provide normal services to the outside world, while the backup cluster does not. Data in the primary cluster is synchronized to the backup cluster in real time to ensure data consistency.

Huawei SD-WAN controller master-slave solution supports multiple master clusters and multiple backup clusters (only one master cluster and one backup cluster are supported)

Remote disaster recovery supports disaster recovery and backup capabilities between two clusters. The number of nodes in the primary cluster and the disaster recovery cluster must be consistent.

QUESTION 130
During the control channel establishment process, the CPE and RR generally establish a BGPEVPN neighbor relationship through the loopback interface.

Correct

Error

QUESTION 131
SD-WAN in the MSP model can typically manage multiple companies, with different companies assigned different MSP accounts or tenant accounts. This model is generally suitable for operators reselling SD-WAN multi-tenant solutions.

Correct

Error

QUESTION 132
What patterns can be identified and analyzed using CampusInsight’s clustering algorithm for connection-related problems?

Manufacturer Level

User Level

AC/AP level

SSID level

QUESTION 133
AP supporting optical-electric hybrid cable can support long-distance power supply over 2000 meters

Correct

Error

QUESTION 134
Which of the following statements about Huawei SD-WAN control channels is correct?

RR reflects TNP information, IPsecSA information, service routing, etc. RR is usually deployed together with the headquarters site.

RR – also commonly known as regional controller

The establishment of IP Overiay tunnel (data channel) mainly depends on TNP (Transport Network Port) information, IPsecSA information, etc.

When service routes are reflected through RR, RR can control route delivery through routing policies (generally issued by iMaster NCE), thereby controlling the flow of services.
