Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 認定 H12-831_V1.0 試験問題:

1. An interface of the switch is in error-down state, probably because the average rate of broadcast packets received by the interface exceeds the maximum threshold set by the administrator in storm control.

A) True
B) False

2. In the BFD (Bidirectional Forwarding Detection) mechanism, two systems establish a BFD session and periodically send BFD control packets along the path between them. If one system does not receive BFD control packets within a specified period, the path is considered faulty.
Which of the following is NOT a possible cause of the BFD session down event?

A) The outbound interface bound to the single-hop BFD session is physically faulty.
B) The remote and local discriminators of the BFD session do not match.
C) The BFD session names configured in the two systems are different.
D) Packets with UDP destination port 4784 are denied.

3. As shown in the figure, the VRRP virtual IP address of network R1 and R2 is configured as
10.0.12.254. After the configuration is completed, the network engineer checks the VRRP status on R1 and R2. Both devices are in the Master state. Which of the following will not cause this phenomenon?

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

4. To support the processing and calculation of IPv6 routes, IS-IS adds a new MLPID in TLV No.
129.
MLPID is an 8-bit field that identifies a network layer protocol message. Which of the following is the MLPID value for IPv6?

A) 236
B) 204
C) 232
D) 142

5. If end-to-end QoS is configured on an MPLS network, the penultimate hop device on the MPLS network can pop MPLS labels from packets based on penultimate hop popping (PHP), so that the egress node can process packets based on the QoS priority in inner packets.

A) TRUE
B) FALSE
