Question 1

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 2

If a performance Issue occurs in Huawei flash storage, an engineer can perform optimization operations according to the storage performance optimization process. Which of the following statements is false about the performance optimization process?

Options :

A :

In the information collection phase, the engineer needs to collect basic information about applications and data, such as the impact of application configurations on data, data size, and read/write ratio.

B :

In the test and application phase, the engineer needs to test the configurations to check whether the optimization objective is achieved. If yes, the engineer can put the system into use.

C :

In the optimization analysis phase, the engineer needs to specify the performance optimization objective, find out the performance bottleneck, and identify the parts that play a key role in Improving the system performance.

D :

In the optimization operation phase, the engineer needs to deploy DR for the service system, and needs to modify multiple configuration at a time during the optimization configuration.

Answer: D

Question 3
