NO.40 In a good Disaster Recovery Plan there are no single points of failure, not even with any single person.

TRUE

FALSE

NO.41 What is wrong with the following description of DAS?

DAS refers to the storage device is directly connected to the server through a SCSI cable or Fibre Channel

The data in DAS mode is still scattered, and each application has a set of storage devices. Management is decentralized and cannot be centralized

When the server and the storage device are directly connected, new application requirements arise, only for the newly added server Separate storage device configuration, resulting in repeated investment

DAS storage space can be fully utilized, storage devices that can be shared by different application servers, fully Leverage idle storage space

NO.42 In HUAWEI OceanStor V3, which licensed feature is best described as: periodically detects hot-spot data and promotes them from low-speed storage media to high-speed media.

SmartMove

SmartMigration

SmartMotion

SmartTier

NO.43 Which of the following statements about RAID 5 and RAID 10 are correct?

The sequential read performance of RAID 5 is lower than RAID 10

If the front-end pressure is sufficient, the sequential write performance of RAID 5 is higher than that of RAID 10.

The random read performance of RAID 5 is lower than RAID 10

The random write performance of RAID 5 is higher than RAID 10

NO.44 LAN Free and Server Free are backup networking methods that have little impact on host performance.

TRUE

FALSE

NO.45 Cloud computing can be used to improve reliability.

TRUE

FALSE

NO.46 In the Huawei OceanStor V3 storage system, which of the following descriptions about mapping snapshot LUNs is correct?

The snapshot LUN mapped to the host can only be read, not written

The activated snapshot LUN can be mapped to the host for reading and writing

The snapshot LUN can only be mapped to the same host as the original LUN

The description of all options is correct

NO.47 In a RAID5 composed of three disks, if 10110110 and 11010011 are written simultaneously, Two data disks with the same stripe, then 01100101 will be written to the verification disk.

TRUE

FALSE

NO.48 The following are the characteristics of the clustered NAS storage architecture: (multiple choice)

Unified namespace, shared globally

High performance, multiple arrays concurrent I/O

Online expansion

can provide block-level storage

NO.49 A device has only one WWNN number, but it can have multiple WWPN numbers.

TRUE

FALSE

NO.50 Compare NAS storage and SAN storage in terms of principle, performance, cost, sharing, and application scenarios.
Which of the following descriptions is correct? (Multiple choice)

NAS performance is higher than SAN, cost is higher than SAN

SAN is mainly suitable for file sharing scenarios, sharing is more convenient

NAS is a storage device with a file system. Sharing files through the network is equivalent to a host in the network.

SAN is a high-speed fiber-connected disk network. It provides disk resources to the host. It has no file system and is equivalent to a network.

NO.51 What is not a deciding parameter for Information LifeCycle Management?

The amount of data.

The format in which the data must be kept.

How long data should be kept.

What to do with data that is no longer required.

NO.52 Which of the following is NOT a port name in Fibre Channel.

FL_Port

E_Port

TX_Port

U_Port

NO.53 When a RAID configuration is in a degraded state it means that no data has been lost yet.

FALSE

TRUE

NO.54 Which of the following disks has the best performance in terms of speed?

NL-SAS

SAS

SSD

SATA

NO.55 Based on the new industrial revolution, what are the changes in the trend of ICT? (Choose all that apply.)

ICT is slowly being replaced by other new technologies such as IT and CT.

The initial phases of ICT focuses on office automation but slowly changed towards changing business flows.

ICT trend is changing slowly with little significant changes.

ICT has become the core in the production systems in the recent years.

NO.56 Which of the following is the common physical size division of the surface of the hard disk? (Choose all that apply.)

Partition.

Sector.

Cylinder.

Track.

NO.57 SmartThin provided by HUAWEI OceanStor V3 storage systems is a technology that manages storage space by allocating storage resources on demand. Based on virtualization, SmartThin reduces physical storage resources to be deployed, maximizing storage space use efficiency.

TRUE

FALSE

NO.58 Situation: Disk Domain A has 40 disks, Disk Domain B has 20 disks. True or False: the rebuild time for a failed disk in Disk Domain B is longer than for a failed disk in Disk Domain A.

TRUE

FALSE
