Question 3

Trueor False, in a Huawei Oceanstro V3 smartVirtualization, eDevLUN and external LUNs are a one-to-one correspondence

A. False

B. True

Correct Answer: A

Question 4

The peak write bandwidth for an application is 10MB / S, with an average write latency of 200KB / s and anaverage write IO size of 4KB (bandwidth utilization of 70%).
If you need to use OceanStor V3 storage array to implement data disaster recovery and set it as asynchronous replication mode, you need the minimum network-wide bandwidth of which of the following?

A. 3.2Mbps

B. 114 Mbps

C. 18 Mbps

Correct Answer: A

Question 5

The Huawei Oceanstro storage system usesasynchronous multi-time cache for asynchronous remote replication to make the remote asynchronous RPO index of the LUN reach the second level.

A. False

B. True

Correct Answer: B

Question 6

Hot-plugging refers toreplacing, adding, upgrading, and removing hardware devices without shutting down the system or power supply. Hot plugging of PCIE is a kind of "no surprise" strategy, that is, when the user unplugs the interface card, you must first notify the system.

A. False

B. True

Correct Answer: B

Question 7

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

A. Oceanstor 9000 uses COW technology for metadata

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

C. According to the snapshotversion 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.

D. Oceanstor 9000 uses ROW technology for data

Correct Answer: C

Question 8

In the N8500 (V200R001) clustered NAS system, when the created file system is used for applications accessing largefiles sequentially, which of the following is correct?

A. From a performance perspective, it is recommended that the total number of files in a single file system be less than 80 million

B. For reliability, the recommended number of file systems is less than 40

C. Large file access business is a largeIO sequential read and write, choose a smaller size of the strip and block size to provide higher bandwidth

D. In order to allow clients to access a single file system, N8000 can provide higher bandwidth and capacity, it is recommended to create a striped file system

Correct Answer: A

Question 9

A. Not prefetched for multi-user multimedia on demand

B. variable prefetching suitable for fixed-size sequential read applications, such as multi-user liunx media on demand, users use the same code stream

C. Intelligent prefetching for a single data stream read application, or cannot determine the sequence of readapplications

D. Fixed prefetch for database applications
