Huawei H12-831_V1.0-ENU 問題集

質問 1：
Both VLAN aggregation and MUX VLAN are deployed on the enterprise network shown in the figure, and all switch interfaces connected to terminals are access interfaces. Given this, match PCI to PC4 with the hosts or servers that they can access on the network. (Note: A host cannot be matched with itself. For example, PCI cannot match PCI.) (Tokens can be reused.)

質問 3：
On the OSPF network shown in the figure, area 1 is an NSSA, area 2 is a common area, and R4 imports an external route 10.0.4.4/32. The router ID of each router is 10.0.X.X, where X is the router number. If the asbr-summary 10.0.4.0 255.255.255.0 command is run in the OSPF processes of R1 and R3, which of the following routers have the route 10.0.4.0/24 in their routing tables?

A. R3
B. R2
C. R1
D. R5

質問 4：
On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements is false?

A. If the link between R1 and SI is disconnected, Rl recalculates the optimal path to R3 and performs path switching instantly.
B. If the link between R1 and SI is disconnected, R1 directly uses the backup path to forward packets to R3 because FRR is enabled on R1.
C. If the link between R1 and SI is disconnected and you check neighbor information on R1, the neighbor relationship between R1 and R2 will instantly display Down.
D. If the link between R2 and SI is disconnected, R1 recalculates the optimal path to R3 and performs path switching instantly.
正解：A

質問 6：
On an MPLS network, when a transit device receives an MPLS packet and is ready to swap labels, it finds that the label value after swapping is 0. In this case, which of the following operations will the device perform?
Options:
A. Swaps label 0 with the original label in the MPLS packet and forwards the packet to the next hop.
B. Pushes label 0 into an outer label of the MPLS packet and forwards the MPLS packet with double labels to the next hop.
C. Forwards the packet to the next hop without processing the label.
D. Removes the label from the MPLS packet and forwards the packet to the next hop.

質問 7：
On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces. The AS number is 6500X, where X is the number of the router. Both Rl and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import-route command.
By default, in the routing table of R3, which of the following is the AS_Path attribute carried in the route to
192.168.1.0/24?
A. 65006, 65005, 65004, 65001
B. 65006, 65005, 65004
C. 65002, 65001
D. 65002, 65005, 65004
正解：B

質問 8：
On the network shown in the figure, VRRP is configured on Rl and R2, and the virtual IP address is
10.0.12.254. After the configuration is complete, the network engineer checks the VRRP status on R1 and R2, and finds that both devices are in the Master state. Which of the following is not a possible cause of this problem?

A. R1 and R2 have different priorities in the VRRP group.
B. The virtual IP addresses configured on R1 and R2 are different.
C. The VRIDs configured on R1 and R2 are different.
D. GE0/0/1 and GEO/0/2 of SW1 belong to different VLANs.
正解：A
