In the Huawei OceanStor system, the size of the file system block is a measure of the size of the accessed file system block. The size of the block is designed according to the size of the data block. Different size of the file system block selects the corresponding file system block, according to the size of the data block. If the business scenario is the media, for large file archiving or stagger I / O backup scenarios, it is recommended to choose the default 64KB disk block size.
- True
- False

An administrator creates 2 libraries (Library#1, Library#2) in Simpana CommCell console, and creates a storage policy Policy#1 using Library#1 to store backup data. Now the administrator wants the backup data to be stored in both Library#1 and Library#2 in turn. So, how to configure the storage policy to meet the requirement? (Choose two.)
- Adding Library#2 as the library for Policy#1.
- Setting Data Paths to “Use Alternate Data Paths” mode.
- Setting Data Paths to “Round-Robin between Data Paths” mode.
- Setting Data Paths to “Use preferred Data Path” mode.

Which of the following description of the application of NDMP backup on the OceanStor 9000 V100R001C30 is wrong?
- Does not support the system disk backup and recovery operations
- When enabling the snapshot-based backup mode, the NDMP backup feature requires the file system to support snapshots. Otherwise, the backup task can not be successfully performed.
- Based on the snapshot backup, snapshots are created for the current directory. Because the extended attributes of the current directory receive the snapshot protection, the current directory extended attributes will be backed up.
- Does not support the system time zone or other time-related adjustments, does not support daylight saving time.

Which description of the the OceanStor V3 file system snapshot feature is wrong?
- In File System Snapshot when you create a snapshot, you simply copy the root of the file system and save it to form a snapshot of the file system.
- Deletion Snapshots use a mechanism for reclaiming space, so snapshot data space is immediately freed after snapshots have been deleted.
- After creating a snapshot in the File System, as the main file system is continuously updated, the original data block will gradually become the space occupied by this quick debt. However, a newly written data will not be included in the snapshot space.
- File system snapshot data can not be deleted directly, and only after the snapshot has been deleted, this part of the space can be released.
-

- Both thin LUN and thick LUN can make initial capacity allocations.
- The maximum capacity of thin LUNs and thick LUNs can be greater than or equal to the available capacity of the storage pool where they reside.
- Both thin LUNs and thick LUNs can be created in bulk.
