Snapshot file system provides only read-only access to external, it cannot provide write operations

File System Snapshot Instantly copy the source file system completely available copy, when due to viruses or man-made misuse and other causes of the original file system is not available, the rollback of the snapshot can restore theoriginal file system.

When the database is protected and the virtual snapshots are used from the end to verify LUN data consistency on the production end and the disaster recovery end. However, the disaster recovery end of the LUNd database can not be started normally. What is the possible reason? (Multiple choice.)

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time.

Disaster recovery storage side of the database resides in the cache has not been written to the hard disk.

A TV station plans to adopt Huawei OceanStor 9000 as a back-end storage system, with 10 OceanStor 9000 C nodes, planned to be deployed in 4 standard cabinets, with all backends connected to a pair of stacked back-end CE6850 switches. There is no single customer in the existing networking standalone management network. Which of the network IP address planning described below is incorrect?

You can plan back-end storage network for 9000 internal communications, without planning gateway address, and front-end network with the same network segment IP address.

Oceanstor 9000 front-end network and management network can be considered together, planning for the same network segment.

Back-end CE6850 switches need to use four stacked cables for stacking connection to ensure bandwidth requirements

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

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

Different empty directories can be assigned different data protection levels to protect the data that will be stored in these directories.

Data written to an OceanStor 9000 is first divided into chunks at a size of 4 GB if the data size is larger than 4GB.

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

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

Which of the following statements about the info stamper in an OceanStor 9000 storage system is not correct?

Oceanstor 9000 uses ROW technology for data

Between snapshots of different versions, there is common data between the snapshot and the current year

According to the snapshot version data objects have a backward dependency, so when reading the snapshot data, according to the object dependencies, the system determines from which object to read.

In order to support business expansion, a large enterprise has decided to purchase two Huawei OceanStor 9000 storage systems to replace the existing NAS systems.

In a media application scenario, large files is an important application feature. Huawei OceanStor 9000 can allocate different configurations according to different users. This avoids some of the unimportant data transition overhead, which of the following description of the quota is correct?

The types of quotas include capacity quota and file quota.

Quota methods include calculating quotas, soft quotas and mandatory quotas.

The system pre-allocates quotas for files before writing the file. When the user cancels the writing of the file being written, the system does not release a pre-allocated quota.

When the user continues to write data, the quota information has been used in the InfoAllocator interface real-time updates.

WORM logs are used to record the logs related to WORM operations and record them according to the time. The monthly log is a file that can be modified and can delete the file.

To prevent changes in the directory or file protection time because of the changes in cluster time, a directory or file is configured with WORM attributes. After the directory or file will use the WORM clock to time, set the WORM clock.When the system will be based on the clock, user's file will not be modified over the protection period.

If the cluster time is earlier than the WORM clock, the WORM clock will be chased every hour for up to 138 seconds to adjust. If the cluster is after the WORM clock, the WORM clock adjusts to the cluster time.

When a directory is configured as a WORM root directory, all subdirectories, new directories and new files in the directory automatically get the parent directory of WORM attributes. These attribute parameters can only be configuredwhen the WORM root directory is set. Only then the user's view can not be modified.

WORM logs are used to record the logs related to WORM operations and record them according to the time. The monthly log is a file that can be modified and can delete the file.
