Free Huawei H13-831_V2.0 Exam Questions

Question 1

What are the correct descriptions of the typical three-tier architecture of cloud computing? Select

A : In the data layer, we recommend that you directly use HUAWEI CLOUD APS

B : You can save data archive logs or logical backups in VBS EVS Disk Backup Service

C : Use Auto Scaling AS to ensure self-healing and adaptive service load of web server and application server nodes

D : ECS at the same layer recommends affinity deployment

Answer: A,C

Question 2

As an architect to design a website up to 100 million times, to achieve high-performance performance in the future, it needs to be achieved through reasonable architecture design. Which of the following describes the elements to consider in the design of a high-performance architecture? (Single).

A : You need to consider the bandwidth of the private network, such as whether the HUAWEI CLOUD data center can withstand the traffic generated by 100 million PVs

B : Comprehensively consider the overall factors that affect the performance of the architecture, such as /O synchronization, concurrency, resource contention, and large data volume. Often, I/O operations, network responses, poor algorithms, databases, and other inefficient resource usage result in poor performance

C : Consider the application itself, such as code execution optimization, software design multi-threading or multi-process

D : Fully consider network performance, such as external network access bandwidth, data transmission efficiency, network path, etc.

Answer: A

Question 3

A game company recently released a new online game product, which was warmly welcomed by users after its launch. However, during the evening rush hour, users often log in congestion and cannot access the system normally, and the user experience feedback is poor. The company asked to resolve this issue quickly, and as the company's IT architect, which of the following would be the appropriate solution? Multiple selection

A : Performance can be scaled by adding more servers to the load-balanced network so that accepted requests can be distributed to different back-end systems according to policy

B : Replace one large resource with multiple small resources to reduce the impact of a single failure on the entire system

C : Build the system on the cloud's dynamically scalable architecture that supports a good user experience and streaming Growth in volume or data size does not degrade performance

D : Interdependencies in the system should be reduced. allowing various components to pass only through specific. technology-independent interfaces (e.g., RES TFUL API). Interact with each other. Technical implementation details are hidden so that the underlying implementation can be modified without affecting other components

Answer: A,B,C,D

Question 4

A social platform business has strong volatility and cannot be predicted in advance. When hot events occur, the service pressure increases sharply, and more ECS is required to ensure high service performance. But when running smoothly and without hot events, the pressure is relatively low and not requiring as much ECS. Which of the following scenarios can help reduce costs for this business? Multiple selection

A : Purchase an on-demand ECS instance and manually scale out during peak service hours, delete the redundant instances

B : and use AutoScali. The periodic policy of the nG service is scaled regularly to cope with service peaks

C : Purchasing Reserved Instances (on-demand packages) can save fees when creating and deleting ECS instances (compared to the subscription cycle).

D : Use the alarm policy of AutoSc a ling service to scale out the capacity horizontally when a high ECS load is detected: Detected When the ECS load is low, it can be scaled down to save costs

Answer: C,D

Question 5

For traditional data center customers migrating to the cloud which of the following services are required to ensure smooth migration and scalability of cloud architecture?

A : L2CG: Interconnect to the second-layer networking of the data center to ensure that the migration IP address remains unchanged

B : Private line: docking to the data center to provide a stable data transmission channel

C : VPC: Refer to the data center component architecture to reasonably plan VPC subnets on the cloud

D : DNS: Configure external domain name and map public network address

Answer: A,B,C
