Question 1

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

Options :

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

Answer: B

Question 2

The cloud-native data lake solution in HUAWEI CLOUD MapReduce provides a leading architecture for separating storage and computing for unstructured data scenarios such as massive government images and videos. Use OBS on the cloud to replace MRS local storage as a big data store. The following description of the OBS service in this solution, which one is wrong? Single selection

Options :

A : Replace the EC algorithm with three copies to reduce the unit capacity cost

B : Provide standard storage, low-access storage, and archive storage in three categories

C : Technology needs to be expanded separately

D : Distributed architecture, horizontally scalable

Answer: A

Question 3

A listed Internet company deployed its core business systems on HUAWEI CLOUD's ECS and bare metal servers On the server BMS, the following description of the company's backup policy, which are correct? Multiple selection

Options :

A :

For scenarios such as accidental deletion of datA. you can use the three-copy mechanism of HUAWEI CLOUD to perform data recovery

B : Regular automatic backups are recommended for the closure of enterprises

C : For scenarios such as software upgrades, it is recommended to use manual backup before upgrading

D : It is recommended to perform off-site backup of key data of the enterprise

Answer: B,C,D

Question 4

The service data system of a department is already running on HUAWEI CLOUD but the response time of user feedback query response is high, which affects the user experience. As a cloud service architect, which of the following bumps should you take to solve this problem?

Options :

A :

The best solution for a particular system will vary depending on the workload type, using data to optimize the choice of resource type and configuration options

B :

Set up performance metrics and monitoring metrics to capture key performance indicators, and use visualization techniques to identify performance issues, hot spots, wait states, or low utilization

C : Use messaging middleware to put frequently accessed data in the Distributed Cache service Redss

D :

By introducing redundancy to eliminate single points of failure, when one fails, the true surplus can simply absorb a larger share of the work

Answer: A,B,C

Question 5

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

Options :

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
