Firmly believe in an idea, the H12-831_V1.0-ENU exam questions are as long as the user to follow our steps, follow our curriculum requirements, users can be good to achieve their goals, to obtain the qualification certificate of the target. Below, I will introduce the H12-831_V1.0-ENU training materials to you from three main aspects, so that you can understand the study materials more deeply.

A wide audience

For example, if you are a college student, you can learn and use online resources through the student learning platform over the study materials. On the other hand, the H12-831_V1.0-ENU study engine are for an office worker, free profession personnel have different learning arrangement, such extensive audience greatly improved the core competitiveness of our products, to provide users with better suited to their specific circumstances of high quality learning resources, according to their aptitude, on-demand, maximum play to the role of the H12-831_V1.0-ENU exam questions.

Effectively improve the user's speed

There are two big in the H12-831_V1.0-ENU exam questions -- software and online learning mode, these two models can realize the user to carry on the simulation study on the study materials, fully in accordance with the true real exam simulation, as well as the perfect timing system, at the end of the test is about to remind users to speed up the speed to solve the problem, the H12-831_V1.0-ENU training materials let users for their own time to control has a more profound practical experience, thus effectively and perfectly improve user efficiency to solve the problem in practice, let them do it keep up on exams.

Highlight key memory methods

The study materials are in the process of human memory, is found that the validity of the memory used by the memory method and using memory mode decision, therefore, the H12-831_V1.0-ENU training materials in the process of examination knowledge teaching and summarizing, use for outstanding education methods with emphasis, allow the user to create a chain of memory, the knowledge is more stronger in my mind for a long time by our H12-831_V1.0-ENU study engine.

Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions:

Question 1

On the network shown in the figure, IS-IS runs on Rl, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. In AS 65000, Ri, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and Rl, R4, R3, and R6 are clients. The IBGP peer relationships are established using LoopbackO. The IP address of LoopbackO on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. Rl and R4 import the external route
192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route
192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?

A. For 192.168.2.0/24, R2 preferentially selects the BGP route received from R3.
B. For 192.168.2.0/24, R5 preferentially selects the BGP route received from R3.
C. For 192.168.1.0/24, R6 preferentially selects the BGP route received from R2.
D. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2.

Question 2

Selective QinQ can add different outer tags to different inner packets. Which of the following statements is false about selective QinQ?

A. Selective QinQ can add different outer VLAN tags to packets with different TTL values.
B. Selective QinQ can add different outer VLAN tags to packets based on 802.1p priorities in inner VLAN tags.
C. Selective QinQ can add different outer VLAN tags to packets with different inner VLAN IDs.
D. Selective QinQ can add different outer VLAN tags based on QoS policies.

Question 3

A network engineer provides a troubleshooting report after rectifying a fault. The actual network is simplified into the one shown in the figure, where R1 and R2 both have OSPF enabled and function as the gateways of PC1 and PC2, respectively .
Given this, which of the following statements are true?

Network Topology:
* R1:
* Interface GE0/0/0 : 10.0.12.1/24 (Connected to R2)
* Interface GE0/0/1 : 192.168.1.1/24 (Gateway for PC1)
R2:
* Interface GE0/0/0 : 10.0.12.2/24 (Connected to R1)
* Interface GE0/0/1 : 192.168.1.2/24 (Gateway for PC2)
Options:

A. R1 cannot ping 192.168.1.12.
B. R1 cannot ping 192.168.1.2.
C. R2 cannot ping 10.0.12.1.
D. PC1 and PC2 cannot ping each other.

Question 4

OSPFv3 runs on R1 and R2 , and the IPv6 addresses configured for the interfaces are marked in the figure .
The router IDs of R1 and R2 are 10.0.1.1 and 10.0.2.2, respectively .

Which of the following statements is true ?

A. The Intra-Area-Prefix-LSA generated by R1 describes four prefixes.
B. The Intra-Area-Prefix-LSA generated by R2 describes three prefixes.
C. The Intra-Area-Prefix-LSA generated by R2 describes four prefixes.
D. The Intra-Area-Prefix-LSA generated by R1 describes three prefixes.

Question 5

On the IS-IS IPv6 network shown in the figure, each interface of R1 and R2 has two IPv6 addresses.
Because the IPv6 address prefixes of R1 and R2 are different, they cannot be used to establish a neighbor relationship.

A. TRUE
B. FALSE
