Question 1

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 2

Huawei OceanStor Pacific series is an intelligent scale-out storage product that supports large-scale scale-out and delivers high reliability. Which of the following statements are false about the product’s reliability?

Options :

A :

In terms of data reliability, multiple RAID policies are supported based on the traditional disk-level RAID mode.

B :

The product adopts Kunpeng processors to integrate functions of multiple chips and effectively improve hardware reliability.

C :

The product leverages link aggregation to ensure transmission link redundancy and performs link switchover or isolation to ensure service continuity if a link becomes faulty or subhealthy.

D :

The product uses the multi-copy technology to implement the intra-node RAID function. If a node is faulty, the system reliability is not degraded and even remains higher than that of the EC mechanism.

Answer: A,D

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

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.

Answer: D

Question 5

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
