ISP convergence speed is faster than BGP, which may cause network traffic loss. By enabling the OSPF and BGP linkage feature of the device, the device can remain () within the set linkage time router, so that the link metric value in the LSA it publishes is the maximum value, thereby telling other OSPF devices not to use this router to forward data to avoid traffic loss.
When encountering a large-scale network cutover project, it can be divided into multiple relatively independent but related small cutovers.
- A . True
- B . False
Which of the following descriptions about configuring roaming groups is wrong?
- A . The Master Controller manages each AC through the CAPWAP tunnel.
- B . Member ACs need to designate an AC as their Master Controller.
- C . Master Controller is a logical role that can be assumed by any ordinary entity AC
- D . After the Master Controller function is enabled, the AC joins the roaming group by default and can manage other ACs.
As shown in the figure, R1 is configured. Which of the following descriptions of IS-IS process 1 is correct?
- A . The device type of R1 is Level -1
- B . The device type of R1 is Level1 -1-2
- C . The device type of R1 cannot be determined
- D . The device type of R1 is Level -2
A user wrote the clear_start_info method to use the OPS function to clear the configuration file of the current network device. The code is as follows: Which of the following descriptions is wrong?
- A . When Ops_conn.create (uri, req_data) is executed, a HITP request of "PUT" operation type will be sent.
- B . Ret is the HTTP status code
- C . Rsp_data is the response data of the system after the request is executed. For the format, please refer to the RESTful API of the network device.

In Huawei Cloud wide area network solution, which of the following technologies can perform performance testing based on real business traffic?
- A . TWAMP
- B . iFIT
- C . Telemetry
- D . BGP FlowSpec
The figure below shows MPLS-VPNL3VPN cross-domain Option C mode 2, in which ASBR-PE2 is connected to CE3 and runs the EBGP protocol. In order to achieve interoperability among all CEs, which address clusters must exist under the process of ASBR-PE2 Neighbor relationship? (Multiple choice)
- A . BGP-LS address family
- B . VPN instance unicast address family
- C . VPNv4 address family
- D . Unicast BGP address cluster
When there are multiple redundant links in the IS – IS network, multiple equal-cost routes may appear.
the following descriptions about equal-cost routing within IS – IS networks is wrong?
- A . If load balancing is configured, traffic will be evenly distributed to each link.
- B . When the number of equal-cost routes in the network is greater than the number configured through commands, and the priorities of these routes are the same, the route with the larger next-hop device System ID is preferred for load balancing.
- C . For each route in the equal-cost route, you can specify a priority. The route with a higher priority will be preferred, and the rest will be used as backup routes.
- D . After configuring the equal-cost route priority, the IS-IS device will not use load balancing when forwarding traffic arriving at the destination network segment, but will forward the traffic to the next hop with the highest priority.
