CThe IP SAN supports the iSCSI protocol.

DThe FC HBA used by the FC SAN can convert SCSI packets into FC packets.

Show Answer

Correct Answer: B, C

The IP SAN can use the existing IP network, and it supports the iSCSI protocol. The FC SAN must be configured with dedicated iSCSI HBAs for servers, and the FC HBA used by the FC SAN cannot convert SCSI packets into FC packets.

Question No. 2

A bank purchases a new storage device. During the RAID level configuration, the bank requires that data reliability be improved and parity data be stored on different disks. Which RAID levels can meet the requirements? (Select All that Apply)

ARAID 0

BRAID 5

CRAID 3

DRAID 6

Show Answer

Correct Answer: B, D

RAID 5 and RAID 6 can meet the requirements as they both improve data reliability by storing parity data on different disks. RAID 0 and RAID 3 do not store parity data on different disks, so they would not meet the bank's requirements.

Question No. 3

Which statements are true about RAID 2.0+? (Select All that Apply)

AAn extent is a block of a fixed size in a chunk group (4 KB by default).

BA chunk group is a logical set of chunks on different disks.

CChunks, which are blocks obtained by dividing each disk at a fixed size, are basic units of a RAID group

DA chunk group is the minimum unit for applying for and releasing space in a storage pool

Show Answer

Correct Answer: A, C

Question No. 4

Suppose, for cost control reasons, a startup company can acquire only one storage device to provide services. However, its services require high hardware reliability, so an engineer recommended a Huawei OceanStor all-flash storage system. Which statements describe the high reliability of the storage system? (Select All that Apply)

AIt supports clusters consisting of multiple controller enclosures to improve the availability of the storage system

BInterconnect I/O modules shorten failover time when a controller fails to provide better reliability, as compared with common I/O modules.

CStandard I/O modules shorten failover time when a controller fails to provide better reliability, as compared with interconnect I/O modules.

DWhen a controller fails, l/Os of the faulty controller are redirected to another controller The host is unaware of the fault and services remain running properly.

Show Answer

Correct Answer: A, B, D

The statements that describe the high reliability of the Huawei OceanStor all-flash storage system are A. It supports clusters consisting of multiple controller enclosures to improve the availability of the storage system, B. Interconnect I/O modules shorten failover time when a controller fails to provide better reliability, as compared with common I/O modules, and D. When a controller fails, l/Os of the faulty controller are redirected to another controller The host is unaware of the fault and services remain running properly. Statement C. Standard I/O modules shorten failover time when a controller fails to provide better reliability, as compared with interconnect I/O modules is false.

Question No. 5

Which statements are true about a dual-controller storage system? (Select All that Apply)

AThere are two working modes: active-standby and active-active.

BIn active-standby mode, if one controller is faulty, services are not affected

CWhen one controller is faulty, the service failover in active-active mode is more efficient than that in active-stand by mode

DIn active-standby mode, only one controller works at a time.

Show Answer

Correct Answer: A, D

In active-standby mode, only one controller works at a time and if one controller is faulty, services are not affected. In active-active mode, both controllers are active and the service failover is more efficient than in active-standby mode.
