Question # 121

What applies to unstructured data? (Multiple Choice)

After being written, the data is not often modified.

Uncertain value.

Large capacity, rapid growth.

Long-term storage required.

Question # 122

Storage array is a network device used to switching network signals or data. It can provide a dedicated communication channel between any 2 nodes in the network that is connected.

TRUE

FALSE

Question # 123

You are the storage administrator of a media company that stores a lot of media files such as videos. You are asked to propose a proper storage architecture for a new storage system that stores all the video and graphic files of the company. The requirement is that it could run on commodity hardware in a distributed manner for unstructured data. Choose which one of the following architecture would be the better option.

Block Storage Architecture.

Clustered NAS Storage Architecture.

Distributed Storage Architecture.

Distributed Object Storage Architecture.

Question # 124

Which of the following descriptions of RAID 1 is incorrect?

RAID 1 writes data to each member disk, the data on each member disk is the same

RAID 1 is verified by XOR algorithm

Normally, RAID 1 reads data from data disk and mirror disk

When the data of some member disks is damaged, RAID 1 allows it to quickly recover data from other member disks

Question # 125

A company uses the CIFS protocol for file sharing, and uses the Homedir sharing method according to the security policy.

All users access the folder and write space.

TRUE

FALSE

Question # 126

What are the three data centers in the disaster recovery plan that 3DC refers to? (Multiple choices)

Production center

The same city disaster recovery center

Remote disaster recovery center

Data center

Question # 127

The SCSI protocol is the basic protocol for host and disk communication. It is operated by the SCSI controller, the controller is equivalent

For a small CPU, it has its own command set and cache.

TRUE

FALSE

Question # 128

Which of the following descriptions of RAID technology are correct? (Multiple choice)

Not every RAID technology can improve write performance

In RAID 0, multiple hard drives are accessed simultaneously (parallel access), speeding up data access performance

The current RAID technology only uses the parity mechanism to protect the data

The performance of all RAID levels increases linearly with the increase in the number of member disks

Question # 129

What is the correct description of the advantages of Huawei RAID 2.0+?

The data is automatically and evenly distributed on the hard disks in the storage pool to avoid uneven heating and cooling of the hard disk, thereby reducing the storage system

Overall failure rate

Overcome the performance bottleneck of the traditional RAID reconstruction target disk (hot spare disk), making the reconstruction bandwidth write bandwidth no longer

It becomes the bottleneck of the reconstruction speed, which greatly improves the reconstruction speed, reduces the probability of double-disk failure, and improves the storage system.

Reliability.

There is no write penalty in RAID2.0+, which overcomes the write penalty in RAID 5 and RAID 6 levels in traditional RAID technology

The impact of the penalty on the write performance of the LUN has greatly improved the performance of the LUN

The data on a single LUN is distributed to many different hard disks, avoiding hard disk hot spots, making single LUN performance and

The capacity has been greatly improved

Question # 130

If a company’s business is to write large-scale data randomly into the LUN, which capacity initial allocation strategy and which

Kind of data migration strategy?

Automatic allocation: migration to the low-performance layer

Priority allocation from high-performance layer: migration to low-performance layer

Priority allocation from low-performance layer: migration to high-performance layer

Priority allocation from the capacity layer: automatic migration

Question # 131

Regarding the new era of ICT and technology, is the following statement correct? (Multiple choices)

Cloud computing (cloud computing) is an increase, use and delivery model of Internet-based related services, usually

Involves the provision of dynamically scalable and often virtualized resources via the Internet

Social media (social media) is a virtual community that people use to create, share, exchange opinions, opinions and experiences

And web platform

CPS (Cyber Phsical System) includes ubiquitous environmental awareness in the future, embedded computing, network communication

System engineering such as Xinhe Network Control is a physical system with functions of computing, communication, precise control, remote collaboration and autonomy

In the new ICT era, the migration of ICT systems from supporting systems to production systems

Question # 132

Remote replication requires master and slave storage from the same manufacturer.

TRUE

FALSE

Question # 133

In the FC protocol, which of the following layers is responsible for encoding and decoding?

A, FC-0

B, FC-1

C, FC-2

D, FC-3

Question # 134

In Huawei RAID 2.0+, when the hot standby strategy of a storage tier is low, the following is about the hot standby reserved by the system for that tier

The capacity description of the space, what is wrong?

When the total number of hard drives in this layer is 10, reserve a capacity equivalent to 1 hard drive

When the total number of hard drives in this layer is 12, reserve the capacity equivalent to 1 hard drive

When the total number of hard drives in this layer is 20, reserve the capacity equivalent to 2 hard drives

When the total number of hard drives in this layer is 48, reserve the capacity equivalent to 2 hard drives
