On the 5 GHz frequency band, it is recommended that high-frequency and low-frequency channels of adjacent APs be staggered to prevent overlapping.)

TRUE

FALSE

NEW QUESTION 135

BGP

OSPF

Static Routing

RIP

NEW QUESTION 137

OSPF hello protocol (default 10s detection)

BFD (Bidirectional Forwarding Detection)

Manual ping test

Static route timeout mechanism (default 3 minutes)

NEW QUESTION 138

Area Border Router (ABR)

Autonomous System Border Router (ASBR)

Designated Router (DR) within the area

All routers within the area

NEW QUESTION 139
In troubleshooting MPLS VPN networks, which command should be used to “view the MPLS Label Forwarding Information Table (LFIB) on the PE device”?

display mpls lfib

display mpls lsp

display ip routing-table vpn -instance

display bgp vpnv4 all routes

NEW QUESTION 140
In Huawei’s WAN solution, for ” backup data transmitted across regions (such as full database backup),” which of the following technologies can “enable breakpoint resumption of backup data transmission and avoid retransmission after interruption”?

Backup data is transferred completely in one go; if interrupted, it must be restarted.

File block-based breakpoint resumption technology (records transmitted blocks and resumes from the breakpoint after interruption).

Reduce backup data transfer rate to decrease the probability of interruption.

Transmit only during off-peak hours at night to avoid interruptions during peak business periods.

NEW QUESTION 141
In an MPLS VPN network, which of the following operations can “ensure that the PE device correctly encapsulates double-layer labels (public network label + VPN label) when forwarding VPN packets”?

Configure the MPLS LDP protocol on the PE device and obtain the public network label.

Enable the MPLS protocol on the CE device and generate a VPN label.

Configure the VPN instance on the P device and assign a VPN label.

No configuration is required; the PE device automatically encapsulates a double-layer label.

NEW QUESTION 142
(On a small- or medium-sized campus network deployed based on the Huawei CloudCampus Solution, an AR functioning as the egress gateway supports web-based network management, registration center query, and DHCP Option 148-based deployment, but does not support CLI-based deployment.)

TRUE

FALSE

NEW QUESTION 143
Huawei’s SD-WAN solution targets ” multi-tenant isolation” scenarios. Which of the following technologies can achieve “isolation of network resources and data between different tenants” and protect tenant privacy? (Multiple choice)

Tenant instance isolation (creating a separate SD-WAN instance for each tenant)

Dedicated bandwidth resources (dedicated bandwidth allocated to each tenant, not shared)

Traffic encryption and isolation (different encryption keys are used for traffic from different tenants)

All tenants share the same network instance, with no isolation mechanism.

Tenant traffic is unencrypted, allowing mutual data access .

NEW QUESTION 144
In Huawei’s WAN bandwidth optimization solution, which of the following technologies can reduce link bandwidth usage and improve transmission efficiency? (Multiple choice)

Data compression (such as the LZ77 algorithm for compressing duplicate data)

Deduplication (eliminating duplicate file blocks transmitted in the link)

Application-layer traffic optimization (e.g., HTTP caching, video traffic shaping)

No compression or caching mechanism; raw data is transmitted directly.

Relying solely on increasing bandwidth capacity without optimizing traffic .

NEW QUESTION 145
In troubleshooting MPLS VPN networks, if you need to “view detailed information about BGP VPNv4 neighbors on the PE device (such as neighbor status and establishment time),” which of the following commands should you use?

display bgp vpnv4 peer [neighbor IP] verbose

display bgp vpnv4 all routes

display ip routing-table vpn -instance

NEW QUESTION 146
In an MPLS VPN network, which of the following factors can cause “VPN users to be unable to communicate,” and are considered common points of failure? (Multiple choice)

VPN instance configuration error on PE device (e.g., VRF binding interface error).

The routing protocol between CE and PE has not been established correctly (e.g., OSPF neighbors are not up).

MPLS LSP not established between PEs (label forwarding path not working)

CE devices are directly connected via a Layer 2 link, without the need for an MPLS VPN.

VPN user routes exist normally on the PE device, and the LSP path is unobstructed .

NEW QUESTION 147
In Huawei’s SD-WAN solution, which of the following technologies can “dynamically switch the encryption algorithm of the VPN tunnel between branch devices and headquarters to adapt to different security compliance requirements “?

Fixed to using the AES-256 encryption algorithm, switching is not supported.

Dynamic negotiation of encryption algorithms based on the IKEv2 protocol (supports switching between Chinese and international cryptographic algorithms)

Unencrypted VPN tunnel, relying solely on MPLS label hiding

The encryption algorithm can be manually reconfigured; dynamic switching is not supported.
