Question 71

In software projects/engineering, CI/CD is a name that is often mentioned. In the following description about CI/CD, which one is wrong?

A.Continuous Delivery: Continuous delivery can release verified code to a repository (such as GiLab)

B.Continuous Deployment: Continuous Deployment extends Continuous Documentation so that a software build can be automatically deployed after passing all tests

C.Continuous Integration: With continuous integration, developers are able to make multiple commits to the repository at any time

D.Continuous integration Through continuous integration, developers need to submit content independently and uniformly at the end of the development cycle

Question 72

The disaster recovery of the database is very important to the production system of the enterprise. The enterprise is currently using the GaussDB (foropenGauss) distributed database as the production database. Now consider using DRS to realize the synchronization ability from the production database to the disaster recovery GaussDBf (oropenGauss) cluster, which of the following scenarios is suitable for this solution/

A.The production library may expand in the future and add new DN

B.The topology of the production database cluster and the disaster recovery database cluster are inconsistent. For example, the production database has 6 DNs and the disaster recovery database has 3 DNs.

C.The disaster recovery database will have access to some query services, and these services will involve multi-table associated queries

D.The business requires that the RTO of the disaster recovery library must be within 5s

Question 73

What are the advantages of Huawei cloud database RDS compared with self-purchased servers to build databases? (Multiple choice)

A.Data backup: ApsaraDB for RDS supports automatic and manual backups, and also supports custom backup storage periods. Self-built databases need to purchase backup equipment, specify settings and post-maintenance by yourself

B.Deployment expansion: ApsaraDB for RDS elastic expansion, opened on demand, self-built database needs to purchase hardware that matches the original equipment, the overall cycle is longer

C.Resource utilization, cloud database RDS is settled on an annual basis. Compared with monthly settlement, the cost is higher. Self-built databases need to consider the peak value. During peak business periods, the resource utilization rate is low

D.Maintenance cost: cloud database RDS basically does not require operation and maintenance, and self-built databases require more labor costs

Question 74

When customers analyze and obtain performance indicators based on stress tests, they usually set thresholds for basic resource performance monitoring data, among which the maximum threshold of CPU usage load is <85%, the maximum threshold of memory usage load is <85%, and I/ O read and write utilization rate maximum threshold <80%

A.False

B.True

Question 75

An enterprise plans to migrate part of its business to Huawei Cloud. In order to ensure the stability and reliability of the business, some test services are migrated for observation in the early stage, in order to monitor the operation of the newly launched business, it is necessary to analyze the log, and through the log analysis, Provide a reference for subsequent business migration.
Which of the following descriptions about Cloud Log Service LTS is wrong?

A.When creating log groups and log streams, it is generally recommended that users create as many as needed to prevent subsequent log storage exceptions due to insufficient numbers

B.Through the LTS service, you can easily and quickly perform log query, and support fuzzy query, keyword query, etc.

C.There is a time limit for log storage. If you need long-term observation in the cloud, you need to back up or dump important logs

D.You can install ICAgent in the elastic cloud host ECS, and monitor and collect logs through services such as LTS and AOM
