Question 1

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 2

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 3

An application running on an ECS instance needs to read a large amount of data from OBS for analysis, and the company's compliance standards do not allow the server to have any Internet access traffic. This scenario can be solved by creating an endpoint that points to the OBS service in the VPC where the ECS instance resides. |

Options :

A : TRUE

B : FALSE

Answer: A

Question 4

The following description of BMS for bare metal services, what are the errors? Multiple selection

Options :

A :

Suitable for online live broadcast of media companies and internal ketone awards of a small and medium-sized enterprise

B : BMS is a bare metal server Therefore, you cannot install the Agent plug-in for service monitoring

C : Supports mounting shared disks and SCSI cloud hard disks

D :

Although it is a physical server resource, it does not support out-of-band management, and HUAWEI CLOUD manages bare metal server resources

Answer: A,B,D

Question 5

The biggest contribution of MapReduce is to realize automatic algorithm parallelization and large-scale distributed computing through a simple interface, which of the following scenarios is it suitable for?

Options :

A : Massive data search

B : Real-time retrieval

C : Web Access Log Analysis

D : Word frequency analysis
