Continue to Read the Huawei H12-831_V1.0-ENU Free Dumps (Part 2, Q41-Q60): You Will Find the H12-831_V1.0-ENU Dumps (V12.02) Are Valid for Preparation

1. A network engineer accidentally deleted the IP address of an interface through the command line.

If he wants to view the deleted IP address, which of the following information should he query?

2. Which of the following operations does a network engineer not need to perform when processing a single-hop BFD session Dom?

3. A network engineer captured a multicast data frame whose destination MAC address is 01-00-5e-00-01-01.

Based on this analysis, which of the following cannot be the destination IPv4 address?

4. When the device logs in to other devices as an SSH client and fails to log in using public key authentication, which of the following are possible reasons? (Multiple choice)

5. The detection mechanism of BFD is that two systems establish a BFD session and periodically send BFD control messages along the path between them. If one party does not receive the BFD control message within a specified time, it is considered that a fault has occurred on the path.

Which of the following reasons will not cause the BFD session to go Down?

6. In the network shown in the figure, R1 and R2 are configured with single-hop BFD detection. The network engineer found that the BFD session was Down, so he queried the configuration related to R1 and R2 BD. The configuration information has been marked in the figure. According to the configuration information, the reason for the BFD session Down is that the time parameters configured on R1 and R2 do not match.

7. If a network engineer forgets the console port password when troubleshooting, Huawei Net Engine AR series routers support configuration in the Boot ROM to skip the console port password startup.

8. The networks of large and medium-sized enterprises can be divided into access layer, aggregation layer and core layer. Network engineers need to formulate cutover plans for any operations performed at any layer that affect the existing network services.

9. A network engineer wants to clear the serial port login password.

Which of the following should he enter?

10. When executing a cutover project, network engineers can perform remote operations at the customer's network maintenance center and guide on-site construction personnel to complete hardware-related operations, such as powering on equipment and connecting equipment.

11. The network logic architecture of a cutover project is shown in the figure. The purpose of the cutover is to expand a network device R4 between R2 and R3. The router IDs of R1, R2, and R3 are 10.0.1.1, 10.0.2.2, and 10.0.3.3 respectively. The OSPF protocol runs between network devices.

After the physical network is connected, when performing the cutover operation, the network engineer first mistakenly imports the backup configuration of R3 into R4.

Based on this scenario, which of the following descriptions are correct? (Multiple choice)

12. In the OSPF network shown in the figure, R1 and R2 achieve intercommunication through Loopback0 interface through OSPF.

At the same time, R1 and R2 have enabled the MPLS LDP function, and the LDP transmission address is the IP address of the Loopback0 interface. The network engineer found that R1 and R2 could not establish an LDP session, so he first executed the command shown in the figure on R2.

Based on this, which of the following reasons may cause the failure of establishing an LDP session between R1 and R2? (Multiple choice)

13. In the networking shown in the figure, R1 and R2 cannot establish an EBGP neighbor relationship through the directly connected interface. The network engineer first checked the BGP-related configurations of R1 and R2, and determined that the reason why R1 and R2 cannot establish an EBGP neighbor relationship is that the Router ID and the interface IP address are inconsistent.

14. A network engineer discovered that a link failure alarm frequently appeared on the interface of a certain device. The interface is an Ethernet optical port.

Which of the following commands can the network engineer use to check the transmit and receive optical power of the interface?

15. A network engineer uses the capture-packet tool to capture the message received by the interface. The figure shows some output information.

What protocol does this message belong to?

16. In the enterprise network shown in the figure, R3 is connected to the enterprise network management server, and all devices in the network communicate with the network management server through VPN.

During the inspection, it was found that R3 had redundant RT configurations.

Which of the following commands can be executed on R3 to delete the redundant RTs without affecting the connectivity of all devices and the network management server? (Multiple choice)

17. The concepts of RD and RT are introduced in BGP/MPLS IP VPN network.

Which of the following descriptions about RD and RT are correct? (Multiple choice)

18. As shown in the figure, R1, R2, and R3 run WPLS, and the administrator configures a static LSP from the 1.1.1.0/24 network segment to the 3.3.3.0/24 network segment.

Which of the following descriptions of this scene are correct? (Multiple choice)

19. MP-BGP adds a new path attribute MP_REACH_NLRI to publish VPNv4 routing information or withdraw unreachable routes in BGP/MPLS IP VPN networks

20. In the BGP/MPLS IP VPN network shown in the figure, which of the following RT value plans can enable Site 1 and Site 2 to communicate with Site 3? (Multiple choice)
