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

正解: B

質問 2

In troubleshooting MPLS VPN networks, if "MPLS LSPs have been established between PE devices, but VPN data still cannot be transmitted," which of the following troubleshooting steps should be performed first?

A. Check if the BGP VPNv4 neighbor between PE devices is established normally.

B. Check if the IP address of the CE device is configured correctly.

C. Check if the binding relationship between the VPN instance and the interface on the PE device is correct.

D. Check if the MPLS protocol configuration on the P device is correct.

正解: C

質問 3

In Huawei's WAN bandwidth optimization solution, for " office documents (such as Word and Excel) transmitted across regions", which of the following technologies can "reduce the transmission of duplicate files and improve efficiency"?

A. Transfer all files directly without performing duplicate checks.

B. Duplicate file filtering based on file fingerprints (files that have already been transmitted will not be transmitted again).

C. Compress the file before transmission without changing the number of transmissions.

D. Sort by file size and transfer smaller files first.

正解: B

質問 4

In MPLS VPN network troubleshooting, if "BGP neighboring between the PE device and the CE device is established normally, but the CE device cannot learn the routes advertised by the PE device", which of the following troubleshooting steps should be performed first?

A. Check if the PE device exports VPNv4 routes to its BGP neighbor (CE device).

B. Check the BGP protocol configuration on the P device.

C. Check if the BGP version of the CE device is consistent with that of the PE device.

D. Check if the MPLS LSP between PE devices is established.

正解: A

質問 5

In Huawei's WAN management platform, which of the following functions can "automatically discover devices and links in the network and generate a visual network topology map"?

A. Bandwidth usage statistics report

B. Automatic generation of fault work orders

C. Batch distribution of device configurations

D. Automatic network topology discovery and mapping

正解: D

質問 6

In Huawei's WAN bandwidth optimization solution, which of the following technologies can
"dynamically adjust the video bitrate based on link load to avoid buffering" for "video conferencing traffic"?

A. Limit video bandwidth and force a reduction in resolution.

B. Relying solely on data compression, without adjusting the bitrate.

C. Dynamic bitrate adaptive technology for video streaming

D. Static bitrate transmission (fixed video resolution)

正解: C

質問 7

In a wide area network (WAN) IPv6 transition scenario, if "an enterprise has both IPv4 and IPv6 servers internally and needs to provide services using both protocols to the outside world," which of the following technologies should be used?

A. NAT64 (only supports IPv6 terminals accessing IPv4 services)

B. IPv6 over IPv4 tunnel (IPv6 service only)

C. Disable one of the protocol services and provide access via only one protocol.

D. IPv4/IPv6 dual-stack technology (the outgoing equipment supports both protocols simultaneously, providing services separately).

正解: D

質問 8

In a WAN BGP protocol deployment, if it is necessary to "filter out routes with a mask length greater than 24 bits when receiving routes advertised by neighbors", which of the following policies should be configured?

A. Enable BGP route aggregation to merge routes with a mask length greater than 24 bits.

B. Apply a prefix-list to the BGP neighbor inbound direction to limit the mask length to 24.

C. Configure BGP neighbor MD5 authentication

D. Adjust the BGP Local Preference property to reduce the priority of long-mask routes.

正解: B

質問 9

In Huawei's SD-WAN solution, which of the following functions can "automatically switch the service forwarding path to the optimal link based on the real-time link quality (latency, packet loss rate)"?

A. Manually switch paths

B. Select path based solely on link bandwidth

C. Static routes with fixed paths

D. Dynamic path switching based on link quality

正解: D

質問 10

In Huawei's SD-WAN solution, which of the following technologies can "ensure that VPN service traffic and Internet service traffic between branches and headquarters are isolated and transmitted on the same physical link"?

A. Use only two independent physical links to transmit different services separately.

B. No isolation mechanism; different services share the same channel.

C. Link aggregation (binding multiple physical links into a single logical link)

D. Network slicing (allocating independent logical channels to different services)

正解: D

質問 11

For the "branch multi-link access" scenario, which of the following functions of Huawei's SD-WAN solution can achieve load balancing and redundancy backup of the links? (Multiple choice)

A. Rapid link failure switching (detecting failures in milliseconds and switching to backup links)

B. No link health check; manual link switching is required after a failure .

C. All traffic flows through a single link, with other links left idle as cold backups.

D. Link health checks (such as ICMP ping, TCP probes to monitor link status in real time)

E. Traffic sharing based on bandwidth ratio (e.g., Internet links handle 70% of the traffic, MPLS links handle 30%).

正解: A,D,E

質問 12

In Huawei's WAN bandwidth optimization solution, which of the following technologies can
"eliminate duplicate file blocks transmitted in the link and reduce bandwidth usage"?

A. Data compression technology

B. Application-layer traffic shaping techniques

C. Link aggregation technology

D. Deduplication technology

正解: D
