Question 1

uses Huawei's optimized FlexFC algorithm. This algorithm allows the system to tolerate simultaneous failures

of three disks, greatly shortening the reconstruction time and

effectively addressing data protection challenges in the large capacity disk era.

Options :

A : RAID 6

B : Flexec

C : OceanProtect

D : SmartTier

Answer: B

Question 2

Huawel OceanStor Pacific series storage supports the volume- or snapshot-based clone feature. Which of the following statements Is false about this feature?

Options :

A :

Small storage space occupation: A clone generated by the storage system is not a full physical data copy, which does not occupy large storage space.

B :

Quick generation: The storage system can generate a clone within several seconds to obtain the consistent copy of the source volume data.

C :

Lossless performance: Based on the ROW mechanism, the done write performance is equivalent to the source volume write performance.

D :

Cascading: Clones can be created based on clone volumes or snapshots of clone volumes in the storage system. A maximum of 64 cascading levels are supported.

Answer: C

Question 3

The scale-out storage system supports cabinet-level security. That is, N data blocks and M parity blocks are stored in different cabinets. If M nodes or M disks are faulty, the system can still read and write data without service interruption or data loss. If M cabinets are faulty, services may be interrupted.

Options :

A : TRUE

B : FALSE

Answer: A

Question 4

In Huawei backup storage OceanProtect X3000, data reduction supports fixed-length (^duplication by default, but does not support variable-length (^duplication. Therefore, fixed-length ded11plication Is mainly used in the backup field.TRUE

Options :

A : TRUE

B : FALSE

Answer: A

Question 5

Which statements are false about software Installation of Huawei OceanStor Pacific series storage systems?

Options :

A :

To install the Distributed Parallel Client (DPC), the switch configuration is required before the installation regardless of whether the low level design (LLD)- or wizard-based installation mode is selected.

B :

To interconnect with FusionCompute during block service installation, storage and compute nodes must be deployed in converged mode, and the management nodes must be deployed in the virtualization environment.

C :

To interconnect with Huawei Cloud Stack during block service installation, storage and compute nodes must be deployed in converged mode, and the management nodes must be deployed in the virtualization environment.

D :

To install the file service in the standard protocol scenario, the switch configuration is not required throughout the entire installation process.
