문제5

Cloud backup service CBR can provide simple and easy-to-use backup services for cloud servers and cloud hard disks. When events such as virus invasion, human error deletion, software and hardware failures, etc. occur, data can be restored to any backup point. Currently, elastic cloud Server backup can be backed up through the "Cloud Server Backup" service and the "Cloud Disk Backup" service.
In the following comparison of the two backups, which items are correct? (Multiple choice)

A. From the dimension of recommended scenarios: cloud server backup, the entire cloud server needs to be protected, cloud hard disk backup, the system disk has no personal data, so only part of the data disk needs to be backed up

B. Dimensions of backup/restore objects: cloud server backup, all cloud disks in the server, cloud disk backup, specified single or multiple disks

C. From the dimension of backup speed: cloud server backup, the backup speed is fast, cloud hard disk backup, the backup speed is slow

D. From the dimension of advantages: cloud server backup, all disk data under the same server are consistent, that is, all cloud hard disks are backed up at the same time, and there is no data inconsistency caused by backup creation time difference, cloud hard disk backup, to ensure data security while reducing backup costs

정답: A,B,D

문제6

A. Only unbound EIPs can be bound

B. An elastic public IP can only be bound to one cloud resource, and the elastic public IP and cloud resources must be in the same region

C. Only unbound EIP addresses can be released. Bound EIP addresses need to be unbound before they can be released.

D. After the elastic public network IP is released, if it is used by other users, you can submit a work order to apply for retrieval

정답: D

문제11
