- B . If there is no routing policy configured for AS Path, then 3002::4/128 must originate from AS 65001
- C . R1 does not have routes for 3002::3/128 and 3002::4/128

An enterprise purchased dedicated lines from two operators. In order to optimize the line, the enterprise uses the BGP protocol to learn the routing entries of the two operators. However, the enterprise found that after such configuration, the traffic of the egress router increased significantly. After investigation, the network engineer found that the traffic of the two operators was transmitted to each other through the enterprise’s egress router. If the enterprise uses the following configuration, it can avoid passing the traffic of the two operators. of traffic.
- A . True
- B . False
Telemetry data subscription defines the interactive relationship between the data sender and the data acquirer. Telemetry subscription methods are divided into two types: among them () subscription method is mostly used for short-term monitoring.
There are two subscription methods for Huawei Telemetry: static subscription and dynamic subscription.
Static subscription refers to the device acting as the client and the collector acting as the server. Initiate a connection from the device to the collector for data collection and submission. Commonly used for long-term inspections.
Dynamic subscription refers to the connection initiated by the device as the server and the collector as the client to the device. Data collection and submission are carried out by the device. Mostly used for short-term monitoring.
In Huawei’s SD-WAN solution, the CPE needs to establish a control channel before it can be managed by the iMaster NCE-WAN controller.
- A . True
- B . False
VPDN refers to a virtual private network built on a public network. Which of the following belongs to VPDN?
- A . VPLS
- B . IPsec
- C . L2TP
- D . GRE VPN
The network administrator enters display telemetry sensor-path on the device to view Telemetry related information. The following is displayed. Which item in the following description is wrong?
- A . For huawei-ifm: interfaces/interface sampling path, the minimum sampling interval of the device is 100ms
- B . Interface statistics can be sampled in parallel, and the sampling path is huawei-ifm: ifm/interfaces/interface/ifStatistics
- C . For huawei-mac: mac/bdMacTotalNumbers/bdMacTotalNumber sampling path, the maximum number of instances that can be collected within 10000ms is 200
- D . The device supports IPV4 route usage sampling. The sampling path is huawei-fibstatus: fibstatus/ipRouteEntryCounts/ipRouteEntryCount.
Which of the following descriptions about Sham link is wrong?
- A . In order for VPN traffic to be forwarded through the IPLS backbone network, the routing cost of Sham 1ink should be less than the OSPF routing cost of the backdoor link.
- B . Sham link is regarded as a link between two VPN instances. Each VPN instance must have an endpoint address of Sham 1ink. It must be one of the VPN address spaces on the PE router and have a 32 bit mask. Loopback interface address
- C . Sham 1ink’s endpoint address is published by BGP as a VPNv4 address. Routes that have passed the Sham link can also be imported into BGP in the form of VPNv4 routes.
- D . Sham link can be manually configured in any area, and the local VPN instance must have a route to the Sham link destination address (the Sham link endpoint address of the opposite PE).

- B . Both SR-MPLS BE and SR-MPLS TE support creating tunnels by specifying the Adjacency SID.
- C . When creating SR-MPLS BE, you can specify the necessary routers
- D . SR-MPLS BE supports tunnel creation by specifying both Node SID and Adjacency SID.
