Question 411

When selecting the data backup type, which of the following descriptions is wrong?

A.If the backup strategy is a full backup combined with a differential incremental backup, after a system failure, if you want to restore the most recent data, you need to restore the data from the last full backup and all differential incremental backups after the full backup.

B.If there is only cumulative incremental backup in the schedule, but no full backup, all files will be backed up when the cumulative incremental backup is performed for the first time.

C.It is recommended to use a combination of three backup types: full backup, differential incremental backup, and cumulative incremental backup.

D.Differential incremental can save storage space to the greatest extent, and the backup window is small.

Question 412

What should be considered in the design of a backup solution? (Multiple choice)

A.Capacity and storage strategy design

B.Backup system migration design

C.Bandwidth and network design,

D.Data and application recovery strategy design

Question 413

Which of the following statements about the erasure code N+M redundancy implemented by Huawei OceanStor 9000 is false?

A.The erasure code algorithm calculates M parity chunks for every N consecutive chunks.

B.Data written to an OceanStor 9000 is divided into chunks at a size of 4 GB

C.Different data protection levels can be set for different directories and files.

D.The utilization rate of storage space is about N/(N+M), and reliability is determined by M, where a larger value of M results in higher reliability.

Question 414

DASH Copy is an optimized auxiliary copy technique. In each copy session, DASH Copy copies all data blocks from a source disk library to the target disk library.

A.TRUE

B.FALSE

Question 415

In the InfoEqualizer feature provided by Huawei OceanStor 9000, a zone is a collection of nodes. Different zones are isolated and provide different services. Nodes in a zone have the same dynamic and static domain names as well as characteristics of automatic load balancing.
