Question 1

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

Accepted Answer

A storage array is a data storage system that provides storage resources, not a network communication system. It does not provide communication channels between network nodes.

Question 2

Based on common ICT architecture, what effect does network latency have on the performance of networks?

Accepted Answer

Low latency means there is less delay in data transmission, leading to quicker and more efficient network performance.

Question 3

Statement 1: Fiber optic cables must be bended with a minimum radius of 10 centimeters. Statement 2: Bends and dirt causes the light signal to be weaker and the sensor cannot detect the light pulse then.

Accepted Answer

The answer of Statement 1: Fiber optic cables must be...

Question 6

Which of the following statements about HUAWEI OceanStor V3 SmartTier dynamic storage tiering technology is NOT true?

Accepted Answer

The SmartTier technology is designed to optimize data placement without affecting service continuity and data availability.

Question 7

Statement 1: a snapshot of a ThinLUN at creation does not occupy storage capacity. The snapshot of a ThickLUN at creation immediately occupies storage capacity. Statement 2: When a snapshot of a ThickLUN exists, there is always space available to store changes to the original data.

Accepted Answer

Question 9

Which of the following statements are true for a NAS solution? (Choose all that apply.)

Accepted Answer

CIFS and NFS are common protocols used in NAS solutions for file sharing. NAS clients typically connect to the NAS server over a network using Ethernet switches.

Question 10

What does the term RPO mean?

Accepted Answer

RPO stands for Recovery Point Objective, which is a term used in data backup and disaster recovery to indicate the maximum tolerable period in which data might be lost due to a major incident.

Question 11

Which of the following are correct steps in a LAN based backup job? (Choose all that apply.)

Accepted Answer

The answer of Which of the following are correct steps...

Question 12

What is typical for a DAS solution? (Choose all that apply.)

Accepted Answer

Question 13

Based on the new industrial revolution, what are the changes in the trend of ICT?  (Choose all that apply.)

Accepted Answer

The trend of ICT has evolved from basic office automation to transforming business processes and has become integral to production systems, reflecting its growing importance in the industrial landscape.

Question 14

The storage controller can only provide processing and caching functions.

Accepted Answer

The storage controller can also manage data storage, handle data redundancy, and ensure data integrity, among other functions.

Question 15

Statement 1: Multimode optic cables are usually longer than single mode cables. Statement 2: Sharp cable bends lead to weaker signal at the end of the cable.

Accepted Answer

Multimode optic cables are generally shorter than single mode cables due to higher dispersion and attenuation. Sharp bends can cause signal loss, making statement 2 true.

Question 16

What statement about the SATA and SAS technologies is true?

Accepted Answer

SATA (Serial ATA) and SAS (Serial Attached SCSI) both use serial communication to transfer data.

Question 17

Given this scenario. A company wants replication of data between two data centers that are 2000 km apart. Which replication method is most recommended?

Accepted Answer

Asynchronous replication is recommended for long distances like 2000 km because it does not require the data to be written to both locations simultaneously, which can introduce latency and performance issues over such a long distance.

Question 18

HyperReplication for HUAWEI OceanStor V3 can use FC links between the data centers. ISCSI links are not supported.

Accepted Answer

The answer of HyperReplication for HUAWEI OceanStor V3 can use...

Question 19

Statement 1: Multipathing is caused by adding redundant hardware. Statement 2: Huawei offers a different version of UltraPath for different operating systems.

Accepted Answer

Statement 1 is true because multipathing is a technology that uses multiple paths to connect a server to a storage device. This can be done by adding redundant hardware, such as multiple network adapters or storage controllers. Statement 2 is also true because Huawei offers a different version of UltraPath for different operating systems. UltraPath is a software that enables multipathing on Huawei storage systems.

Question 20

Statement 1: Synchronous replication is often possible over distances of more than 100 km. Statement 2: Asynchronous replication must be used when the host has a file system that is Linux based.

Accepted Answer

The answer of Statement 1: Synchronous replication is often possible...
