Huawei H12-831_V1.0 exam candidates will surely pass the Exam if they consider the H12-831_V1.0 dumps learning material presented by ExamcollectionPass.

NO.100 As shown in the figure, Site1 and Site2 need to achieve mutual access through the operator’s BGP/MPLS IPVPN. It is known that the public network tunnel between PE1 and PE2 has been established (the label information is shown in the figure), and PF1 has advertised the 192.168.1.0/24 network segment route in Site1 to PE2 through the MP.JIBGP neighbor relationship, and the route learning is normal.

NO.107 Regarding the MPLS forwarding process, which of the following description of Ingress node forwarding is correct? (Multiple choice)

After receiving the data packet, the Ingress node will first check the ILM table to find the Tunnel ID

Press the obtained label in the IP packet, and process EXP according to the QoS policy, and process L at the same time, and then send the encapsulated MPLS packet to the next hop

Find the corresponding NHLFE entry according to the Tunnel ID of the ILM table, and associate the LFIB entry with the NHLFE entry

Check the NHLFE entry, you can get the outgoing interface, next hop, outgoing label, and label operation type. The label operation type is Push

NO.108 What check items can be set in IPSG? (Multiple choice)

MAC address

Outgoing interface

VLANID

IP address

NO.110 In an MPLS VPN network, data packets are forwarded when they enter the public network. Will be encapsulated with two layers of MPLS labels. Which of the following description is correct about the processing of the data packet? (Multiple choice)

The packet is forwarded to the Egress PE device after the outer label pops up on the penultimate hop device

The Egress PE device correctly sends the data packet to the corresponding VPN according to the inner label

The outer label of the packet received by the penultimate hop device is 3

The Egress PE device receives untagged IP packets
