Huawei H12-831_V1.0 Actual Free Exam Questions & Community Discussion

In a VRRP deployment, Router A has priority 120 and Router B has priority 110. Router A fails and Router B becomes Master. After Router A recovers, Router B continues forwarding traffic.
Which feature explains this behavior?

On the OSPFv3 network shown in the figure, the LSDB of R2 contains ____ Router-LSAs. (Enter only digits.)

On the IS-IS IPv6 network shown in the figure, multi-topology is enabled on all routers. The IPv6 address of Loopback0 on R4 is 2000::/128. The IPv6 summary 2000::/64 level-1-2 command is configured in the IS-IS processes of R2 and R1.
Which of the following statements is false?

In a networking environment where the network is relatively stable and has high requirements for route convergence time, you can specify the OSPF LSA update interval to 0 to cancel the LSA update interval, so that topology or route changes can be immediately published to the network through LSA, thereby speeding up the route convergence speed in the network.

On the network shown in the figure, the DHCP server function is enabled on GE0/0/0 of R2, and the address pool is an interface address pool. When GE0/0/0 and GE0/0/1 of R1 function as DHCP clients, only one interface can obtain an IP address by default.

The equipment operating environment refers to the external environment such as the equipment room, power supply, and heat dissipation where the equipment operates. This is the basic condition for the equipment to operate. For the maintenance of the equipment operating environment, the staff can only complete it by visiting the site in person.

In the network shown in the figure, OSPF protocol is running between R1, R2, and R3, and OSPF BFD feature is turned on. IBGP neighbor relationship is established between R1 and R3 using loopback interface. If GE0/0/1 interface of R2 is shut down, and BGP neighbor relationship is checked on R1, by default, which of the following is the longest time for R1 BGP neighbor relationship to change from Up state to Down state?

When an IP packet passes through an MPLS network, an MPLS device processes the TTL value in the packet.
If the pipe mode is used in the topology shown in the figure, which of the following is the TTL value in the IP packet?

On the IS-IS IPv6 network shown in the figure, after the network becomes stable:
R1 can ping 2000:12::0, and the display ipv6 neighbors command can be used to display the MAC address corresponding to 2000:12::0.

Is this statement TRUE or FALSE?

When an IP packet enters the MPLS domain, the ingress node checks the Tunnel ID corresponding to the source IP address. When the Tunnel ID is not 0x0, the ingress node performs MPLS forwarding on the packet.

Which of the following TLVs is added to IS-IS to support multi-topology?

The exchange of Hello messages between two LSRs (Label switching Routers) triggers the establishment of an LDP session. The Hello message carries the transport address. The device with the smaller transport address will act as the active party and initiate the establishment of a TCP connection.

There are multiple types of MAC address entries on the switch. Which of the following types of entries can discard messages by matching the source MAC address of the received message, thereby achieving the purpose of filtering out illegal users.

The flexible QinQ function can add different outer tags according to different inner messages.
Which of the following descriptions about the tag addition of flexible QinQ is wrong?

For high reliability purposes, the following LDP messages are transmitted through TCP: discovery messages, session messages, advertisement messages, and notification messages.
