문제1

Redundancy policies are involved in the planning of storage pools on Huawei OceanStor Dorado series storage devices. Which of the following statements are true about redundancy policies?
(Choose all that apply.)

A. An enclosure redundancy policy can be set only when a storage pool is being created. After the storage pool is created, the redundancy policy cannot be modified.

B. The enclosure redundancy policy enables the system to tolerate failure of a single disk enclosure without service interruption or data loss.

C. At the same RAID level, the RAID usage of the disk redundancy policy is smaller than that of the enclosure redundancy policy.

D. An enclosure redundancy policy does not tolerate enclosure power outage, whereas a disk redundancy policy does.

문제2

An enterprise customer has purchased a Huawei OceanStor Pacific scale-out storage system for service configuration. An engineer wants to deploy the NFS file sharing service on the storage system and configure the HyperReplication feature. Which of the following configuration operations are correct? (Choose all that apply.)

A. When configuring HyperReplication, the engineer needs to configure the replication network route information on the primary storage system. The replication network route does not need to be configured on the secondary storage system.

B. After a converged storage pool is created, the engineer needs to enable the file service. The HDFS or object service does not have to be enabled.

C. To use the NFSv4.0 protocol for share access, the engineer can run the "change service nfs_config nfsv40_status=enable account_name=?" command to enable the NFSv4.0 service.

D. When configuring HyperReplication, the engineer needs to create a remote replication pair on both the primary and secondary storage systems and then add a remote device.

문제3

FILL BLANK
In RAID 2.0+, the storage system divides each disk in a storage pool into 4 MB ____ for logical space management.

정답:

CKs
Explanation:
In Huawei RAID 2.0+, each disk in a storage pool is divided into fixed-size 4 MB chunks (CKs) for logical space management.

문제4

When purchasing storage devices, which of the following criteria will an enterprise use to evaluate the storage devices? (Multiple choice)

A. Cost

B. Occupied space

C. Competitiveness

D. Accessibility

정답: A,B,C

문제5

A financial customer has purchased several Huawei flash storage devices for service deployment. An engineer configures the SmartMigration feature on the storage devices. If the engineer wants to start LUN migration synchronization, the engineer can run the "change lun_migration_split consistency" command.

A. FALSE

B. TRUE

정답: A

문제6

FILL BLANK
The LUN active-active balancing feature of Huawei all-flash storage integrates the global
________ design. The front-end interface board evenly distributes I/Os to the target controller for load balancing.

정답:

Cache
Explanation:
The LUN active-active balancing feature in Huawei all-flash storage integrates the global cache design, allowing both controllers to access shared cache resources. This enables the front-end interface board to evenly distribute I/Os across controllers, achieving optimal load balancing and high performance.

문제7

A financial customer has purchased several Huawei flash storage devices to deploy HyperMetro services. During operation and maintenance, an engineer discovers that the health status of a HyperMetro vStore pair is faulty. This indicates that the running status of the HyperMetro vStore pair is invalid or unsynchronized.

A. FALSE

B. TRUE

정답: B

문제8

When delivering Huawei all-flash projects, Huawei engineers introduced the HyperCDP feature of flash storage to customers. Which of the following statements are true about this feature?
(Choose all that apply.)

A. HyperCDP snapshots cannot be directly mapped to hosts. To read data from a HyperCDP snapshot due to actual service requirements, the administrator needs to share the file system with the host so that the host can read the source file system data at the point in time when the HyperCDP snapshot was created.

B. Copies created using HyperCDP can be used for data analysis and application testing.

C. When an application server sends a request to write data to the source LUN after a HyperCDP snapshot is created, the storage system uses the copy-on-write (COW) technology to save the new data to a new location in the storage pool and directs the source LUN's pointer to the new location.

D. HyperCDP is a high-density snapshot and requires the system to construct file system objects.
Therefore, the system memory usage is high.

문제9

Engineer A used UltraPath multi-path software when deploying Huawei converged storage.
Which of the following descriptions of the multipath software load balancing algorithm are wrong?
(Multiple choice)

A. The min-task algorithm is a polling algorithm and can be used in scenarios where the differences in the service IO models sent by the host are small.

B. Algorithms can be divided into three categories: min-queue-depth algorithm, round-robin algorithm and min-task algorithm

C. The round-robin algorithm is a minimum task algorithm and can be used in scenarios where the business IO model data blocks sent by the host are large.

D. The min-queue-depth algorithm is the minimum queue depth algorithm, which is configured by default in the multipath software.

정답: A,C

문제10

When delivering a Huawei OceanStor Pacific scale-out storage project, an engineer introduced the end-to-end data integrity check technology of scale-out storage to the customer. Which of the following statements are false about this technology?

A. For silent data scenarios such as bit change and read offset, the end-to-end data integrity check technology supports logical block addressing (LBA) check of clusters and hosts.

B. This technology enables the storage system to implement periodic background data integrity check. When the service load is heavy or service access is frequent, the system automatically starts periodic background data integrity check and self-healing.

C. In this technology, write requests are checked at the system entry (virtual block service). User data is checked again in the object storage device (OSD) before being written to disks. Data is written to disks only after the data integrity check succeeds.

D. Block, NAS, and object services support end-to-end data integrity check, but the HDFS service does not.

정답: B

문제13

The OLAP database service scenario differs from the OLTP database service scenario. The OLAP database service scenario mainly involves random small I/Os with more read operations than write operations, while the OLTP database service scenario mainly involves sequential read of large I/Os.

A. FALSE

B. TRUE
