An industry customer has purchased two Huawei OceanStor Pacific scale-out storage devices and deployed them in different equipment rooms. Now an engineer wants to configure the HyperMetro feature on the two devices in static priority mode. Equipment room A is the preferred site. After the link between the two storage devices is down, what is the running status of the HyperMetro pair and what is the arbitration result?

A.

The running status of the HyperMetro pair is "Normal". The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B continues providing services.

B.

The running status of the HyperMetro pair is "To be synchronized". The arbitration result is that the volume in equipment room A continues providing services and that in equipment room B stops providing services.

C.

The running status of the HyperMetro pair is "Normal". The arbitration result is that the volumes in equipment rooms A and B continue providing services.

D.

The running status of the HyperMetro pair is "To be synchronized". The arbitration result is that the volume in equipment room A is inaccessible and that in equipment room B stops providing services.

Huawei OceanStor Pacific series storage systems support the _______ client access mode. This mode allows a single client to connect to multiple storage nodes and supports MPI-I/O access. (Enter an acronym.)

When delivering a flash storage project, Huawei engineers introduced the multi-tenant feature of flash storage to the customer. This feature isolates service data. Although different tenants cannot access each other’s LUNs, they can access each other’s file system.

A.

TRUE

B.

FALSE

An Industry customer purchases several Huawei flash storage devices for service deployment. During an inspection, an engineer finds that some storage components are faulty and need to be removed and replaced. Which of the following statements Is true about the part removal and replacement?

A.

The interface modules and system subracks of the storage device can be replaced independently.

B.

The CPUs of the storage device cannot be replaced independently, but can be removed independently.

C.

The memory modules and system disks of the storage device can be removed and replaced independently.

D.

The coin batteries of the storage device cannot be replaced or removed.

When delivering a Huawei flash storage project, an engineer introduced the SAN/NAS Integrated architecture to the customer. Which of the following statements Is false about the architecture?

A.

The protocol layer is responsible for protocol parsing and permission management. SAN and NAS are two sets of semantic logic. Therefore, different service entry components are used.

B.

The space management layer uses the active-active high reliability mode to provide reliable data protection capabilities based on actual service scenarios of customers.

C.

The software architecture consists of the following layers from top to bottom: protocol, data service, cache, file and block space management, and storage pool.

D.

At the protocol layer, NFS/CIFS supports direct TCP offload engine (DT06), while ISCSI does not.

A financial customer purchases several Huawel OceanStor Dorado series storage devices for service deployment. During a maintenance process, an engineer needs to use DeviceManager to collect disk health analysis (DHA) logs. Which of the following is not Included in DHA logs?

A.

I/O statistics

B.

Routine disk health statistics

C.

Device latency statistics

D.

Disk life span information

Huawei OceanProtect Appliance provides strong data protection capabilities. Which of the following statements is true about the functional architecture of the Appliance?

A.

ProtectManager is a data flow module that performs data backup, restoration, replication, archive, and copy mounting.

B.

File system management and protocol access are implemented by the data protection layer.

C.

During data protection, the Appliance can protect application data without backup agents.

D.

DataEnable Engine is a data enabling module for global search and data anonymization.

In Huawei all-flash storage, the SmartDedupe and SmartCompression features reduce redundant data space consumption and improve the transmission and storage efficiency of a storage system. Which of the following statements about the features is false?

A.

Post-process compression means that data is first written to storage media and then read for compression.

B.

During inline deduplication, the system divides data into blocks and then calculates fingerprints for the blocks.

C.

During similarity-based deduplication in the background, the system does not divide data into blocks and can directly calculate similar fingerprints.

D.

Backup storage supports deduplication and compression of file systems.

A school has purchased two Huawei OceanStor Pacific series storage devices for service deployment. An engineer wants to configure the distributed parallel client (DPC) on the storage devices. Which of the following statements is false about the engineer's configuration?

A.

If upper-layer services require high data security, the engineer needs to set the storage pool type to "Self-encrypting" when creating a converged storage pool.

B.

Before creating a converged storage pool, the engineer must enable the file service for nodes on DeviceManager.

C.

When creating a namespace, the engineer needs to select a security style and application type.

D.

When the storage network is a Remote Direct Memory Access over Converged Ethernet (RoCE) network, the engineer can run the "systemctl stop lldpad.service" command to disable the lldpad service.

In Huawei flash storage. If an engineer wants to remotely power on the storage system, the engineer must make an appropriate networking plan for the controller enclosures of the storage system. Which of the following statements is false about the networking principles of a storage system with multiple controller enclosures?
