The ipv6 enable topology standard is configured in the IS-IS protocol view. The meaning of this command is that IPv4 and IPv6 share the same topology.
- A . True
- B . False
In the scenario of dynamically establishing an SR Policy tunnel through a controller, which one of the following descriptions of the SR Policy solution architecture is wrong?
- A . The controller issues configuration controls such as business interfaces and routing policies through NETCONF.
- B . The controller delivers SRv6 SID and other information through Telemetry and builds device SID entries.
- C . The controller delivers the color, headend, endpoint and other information of the SR Policy through the BGP IPv6 SR Policy.
- D . The controller collects tunnel topology information through BGP-LS and calculates the SR Policy path
When viewing the debug output through the SSH terminal, a lot of information pops up. Which of the following operations can prevent the Monitor terminal from popping up debug messages? (Multiple choice)
- A . Open Notepad, enter undo debugging all, copy this line of command, and paste it into the Monitor interface
- B . Open Notepad, enter undo terminal monitor, copy this line of command, and paste it into the Monitor interface
- C . Open Notepad, enter undo terminal debugging, copy this line of command, and paste it into the Monitor interface
- D . Exit the current Monitor interface and log in to the device via SSH again to open a new Monitor interface.
In the HQoS scenario, which of the following queue scheduling methods can be used for flow queues and user queues? (Multiple choice)
- A . WFQ+PQ
- B . WFQ+WRR
- C . WFQ
- D . PQ
Huawei SD-VAN solution architecture has three channels. Please match the channels in the picture with their names one by one.

An engineer uses two routers to conduct IPv6 service testing and runs OSPFv3 to realize the interconnection of IPv6 networks. It is required that R1 can access the loopback interface address of 2.
The engineer looked at the OSPFv3 routing table entries of R1 as shown in the figure and found that there was no route to the loopback interface address of R2. This result could not be caused by which of the following reasons?
- A . R2 advertises the loopback port into a different 0SPFv3 process
- B . R2 does not advertise the loopback interface address using the network command in area 0
- C . R2 does not enable OSPFv3 on the loopback interface
- D . R2 is not configured with the Router ID used in the OSPFv3 process.
In Huawei’s SD-WAN networking solution, the topology of different VNs must be consistent.
- A . True
- B . False
The SSH connection protocol multiplexes encrypted session connections into several logical channels. What types of logical channels can be created based on an SSH session connection? (Multiple choice)
- A . SFTP channel
- B . Session channel
- C . X11 channel
- D . TCP/IP forwarding channel
The SD-WAN network topology based on Huawei’s SD WAN solution is as shown in the figure: the headquarters has dual HUB sites, and the HUB and RR are co-located. The sum of all sites in different regions is 350, including 220 dual gateway sites and single 130 gateway sites. After calculation, an RR device needs to establish () BGP neighbor relationships.
All routers in a network enable the SR-MPLSTE function based on OSPF. As shown in the figure is the adjacency label allocation network diagram. Which of the following adjacency labels are allocated by router P3? (Multiple choice)
- A . 9003
- B . 9002
- C . 9005
- D . 9006
