NO.18 When an engineer understands the local write process of the storage system, he believes that the host first writes the IO request to a certain controller engine, and then the engine writes the value directly to the engine’s local hard disk.

NO.19 Engineer C maps the storage to the file server for storing various files of the enterprise. One day, the file system was attacked by a virus and the file could not be opened normally. In order to allow the files to be accessed normally, storage engineer C performs a snapshot rollback operation. Which of the following descriptions is wrong?

NO.20 Images and music belongs to unstructured data.

NO.21 Which technology’s the basic unit is Extent of RAID 2.0+ technology in the storage pool? (Multiple choice)

NO.22 When there are bad sectors or bad blocks on the hard disk, which reconstruction method is used?

NO.23 Which of the following descriptions is correct?
Description 1: LUN is composed of multiple Extents in the storage pool.
Description 2: LUN can contain one or more types of Extent.

NO.24 IP scale-out is the scale-out that constructs the pcie protocol and is generally used in high-end industrial storage business scenarios.

NO.25 Which of the following descriptions are correct about IP scale-out expansion? (Multiple Choice)

NO.26 Distributed object storage has a unified name space and supports online expansion.

NO.27 The deduplication feature reduces space through compression.

NO.28 The IT storage equipment of a bank was relocated, and the mechanical hard disk could not be read. The engineer judged that the hard disk was broken. What are the possible reasons? (Multiple Choice)

NO.29 In the Huawei OceanStor V3 storage system, which of the following descriptions about file-level HyperSnap feature data recovery is correct? (Multiple choice)

NO.30 Description 1: The data recovery of the snapshot depends on the source data.
If the source data is physically damaged, it cannot be recovered.
In this case, the clone can still recover the source data.
Description 2: After the source data is damaged, LUN copy must make a complete copy of the backup data to restore the source data.
The clone only needs to restore the damaged data, which greatly shortens the recovery time.
-Snapshot: The data recovery of a snapshot depends on the source data. If the source data is physically damaged, it cannot be recovered. In this case, the clone can still recover the source data.
-LUN copy: After the source data is damaged, LUN copy must make a complete copy of the backup data to restore the source data. The clone only needs to restore the damaged data (incremental copy), which greatly reduces the recovery time.
-Remote replication: Remote replication can only protect data between storage devices. The hardware cost is high, and the remote link bandwidth is usually low, and the data recovery time is long. The cloning can realize data protection in the storage device, which can effectively save expenses and shorten the data recovery time.

NO.31 Create a Thin LUN on Huawei OceanStor V3 with a capacity of 100G and an initial allocated capacity of 10G. After the LUN is mapped to the Windows 2012 host, the corresponding disk is scanned on the host. The displayed capacity of the disk should be 10G.
