Question 1

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 2

Which of the following descriptions of stateful and stateless apps is correct? Single selection

A : Tenants can deploy stateless applications through Auto Scaling to ensure high scalability of applications

B : Tenants can deploy stateful applications through Auto Scaling to ensure high scalability of applications

C : The scalability of stateful applications is better than that of stateless applications

D : The performance of stateful applications is better than that of stateless applications

Answer: A

Question 3

In the overall architecture diagram of Data Lake Exploration DLI I, the data layer can be compatible with the data of various data sources, and the intermediate engine adopts Storm As the core engine, it can provide a variety of interface calls to the outside world. which can support the analysis and calculation of various industries. Radio

A : TRUE

B : FALSE

Answer: B

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

The following description of using HPA+CA to achieve automatic scaling of workload and node linkage, which one is wrong? Radio

A : CCE cloud container engine supports the creation of CA policies, scales capacity according to CPU/memory allocation ratio, and periodically scales nodes according to time

B : HPA expands according to the monitoring standard. and when the cluster resources are insufficient, the newly created pod will be in the Running state, CA All Running states are checked for POD According to the user-configured scaling policy, select the most suitable node pool to scale

C : Under normal circumstances, the two need to be used together, because HPA requires sufficient resources in the cluster to successfully expand. and when the cluster resources are not enough, the CA needs to expand the nodes so that the cluster has sufficient resources

D : When the cluster has a large amount of spare resources after HPA scale-in, the CA scale-in node needs to release resources so as not to cause waste
