NEW QUESTION 46
Huawei Oceanstor9000 provides a single file system externally and manages it through a unified file system namespace.
Which namespace statement is not true?

Namespaces are automatically created during OceanStor 9000 startup and are named after the system name.

As the root directory of the entire system, the namespace cannot be shared or accessed. However, its sub-directions can be shared and accessed.

Unified namespace provides a pooled storage resources pool to centrally manage and allocate storage space.

All shared directories are subdirectories in the standard namespace.

NEW QUESTION 47
In Huawei OceanStor 9000, what technologies does the application support to improve performance? (Multiple Choice)

Support 10GE and PCIE networking, through high-speed interconnection between nodes, reduce the internal delay of the system and provide excellent performance.

When a hard disk has multiple-object write requests at the same time, it supports merging into continuous large IO to significantly improve system performance.

When performing internal file copying, it is directly completed within the system at high speed without going through the client.

Support SMB3Multichannel function, make full use of multi-core CPU and bandwidth resources in the client, and significantly improve performance.
