As an operations implementer for the company, which of the following methods should you deploy? Multiple selection

A : The amount of new service access is not large, according to the service access, the WEB side and application can be deployed on a single machine, and the new cloud host can be re-applied to resume business after the failure

B : Data backup is required for new service data security considerations. WEB TERMINALS AND APPLICATIONS CAN BE BACKED UP BY HOST BACKUP OR IMAGE PACKAGING. The database is backed up at the same time as a highly available deployment

C : With the needs of business development, business needs to expand. THE WEB SIDE AND THE APPLICATION ARE SCALED HORIZONTALLY, AND THE DATABASE IS VERTICALLY EXPANDED

D : Business systems have high requirements for databases, and primary/standby instances can be deployed from the perspective of high availability to ensure data reliability

Answer: B,C,D

Question 2

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

Question 3

B : Deploy three servers in each of the two zones and use auto scaling to ensure that nodes can be replaced after they are damaged

C : Deploy 6 servers in each of the two zones and use auto scaling to ensure that nodes can be replaced after damage

D : Deploy three servers in each of the three zones and use auto scaling to ensure that the can be replaced after the node is damaged

Answer: D

Question 4

Bob uses UGO to migrate the database structure on HUAWEI CLOUD which of the following is correct? Multiple selection

A : Before creating a migration task, obtain the results of the evaluation task and confirm the target database

B : If the object that succeeds in the syntax conversion stage fails during the migration verification, you can check the user permissions of the target database and the existence of dependent objects of the failed object

C : In the conversion configuration, when modifying the tablespace configuration, select Do not annotate the tablespace, and the tablespace configuration of the table creation statement in the destination database is consistent with that of the source database
