An enterprise has deployed multiple applications, such as desktop cloud, database, video on demand (VoD), and backup. These applications occupy a large amount of storage resources. The enterprise plans to use the deduplication and compression features. Which of the following configurations are recommended?

A Deduplication and compression are not recommended for VOD scenarios because video files have been compressed by application software and re-compression will be inefficient.
B Deduplication is recommended for desktop cloud scenarios because there is a large amount of duplicate data among multiple virtual images.
C Compression is recommended for database-scenarios because a large amount of data needs to be stored.
D Deduplication is not recommended for backup scenarios because all backup data must be retained.

A service host is connected to a storage device through Fibre Channel SAN. However, the service host cannot detect mapped LUNs after scanning. Which of the following are possible causes?

A The Fibre Channel module on the service host is faulty.
B No multipathing software is installed on the service host.
C Zones are incorrectly configured.
D The storage network is blocked by the firewall.

Which of the following is not supported by HyperMetro?

A Data zero copy
B FastWrite
C Memory ballooning
D Optimized cross-site access

SmartCache can support both SAN and NAS services.

A True
B False

In Huawei distributed storage systems, the asynchronous remote replication architecture of the block service establishes an asynchronous remote replication relationship based on a block service cluster. This architecture also synchronizes data between primary and secondary volumes based on differential data. All the data generated on the primary volume after the last synchronization will be written to the secondary volume in the next synchronization.

A True
B False

Which of the following statements about the versioning for buckets are correct?

A You can check whether the versioning is enabled by viewing its state.
B You can use versioning to save, query, and restore objects of different versions.
C The versioning state can be configured and queried.
D Versioning cannot be used to retain and archive data.

The data, logs, and change records of a medium- or large-size database are stored in LUN 1, LUN 2, and LUN 3, respectively. Remote replication tasks 1, 2, and 3 are created and the replication pairs are added to a consistency group. Which of the following statements are true?

A The three remote replication pairs can be added to a consistency group only on the primary storage system, and their secondary LUNs must be on the same remote storage system.
B If remote replication task 2 is abnormal during data synchronization, remote replication tasks 1 and 3 are stopped immediately.
C If remote replication task 2 is abnormal during data synchronization, remote replication tasks 1 and 3 are not stopped. After the fault is rectified, remote replication task 2 continues.
D In the event of a disaster, data can be restored from the secondary storage system to ensure availability of the database.

A company deploys a Huawei distributed storage system to build a new online transaction system. The company deploys database application software of the transaction system on virtual machines (VMs). Multiple data volumes are mounted to VM. What are the best methods to ensure data restoration reliability?

A All volume snapshots must be created at the same time.
B A snapshot and a consistency snapshot comply with the dependency consistency principle.
C Multiple data volumes used by the database do not have to use the consistency snapshot.
D Different data volumes need to be restored in sequence.

A live gaming platform uses the FlashLink multi-core technology of Huawei OceanStor all-flash storage for its services. Which of the following describes core grouping in CPUs?

A A request is processed by one core until its completion. Cores are lock-free to avoid frequent switchovers among the cores.
B Read/write I/Os are deployed in different core groups from other types of I/Os to avoid mutual interference.
C The controller works with SSDs to identify hot and cold data in the system, improve garbage collection efficiency, and prolong the service life of SSDs.
D vNodes are bound to CPUs to reduce the overheads for scheduling and transmission across CPUs.

Which of the following statements about InfoStamper are correct?

A If file data in a source directory encounters non-physical damage such as incorrect deletion, overwriting, or virus attack, you can restore the data by accessing the file in the snapshot directory generated before the fault.
B After a remote application task starts, snapshots are created at a preset interval. Then the incremental data at the snapshot point in time is replicated to the secondary directory.
C The antivirus server reads files from snapshots for virus scanning, removal, and isolation.
D Snapshots prevent data loss caused by consecutive faults and tolerate faults of sub-healthy disks.

Compared with traditional RAID algorithms, the erasure code redundancy technology provides higher reliability and more flexible redundancy policies. Which of the following statements about the working principle of erasure code is false?

A Data to be written is divided into N data blocks of the same size.
B The erasure code algorithm calculates M parity blocks for every N consecutive data blocks. (The value of N is smaller than that of M.)
C N+M data blocks are concurrently stored to different nodes.
D In erasure code storage mode, a concurrent failure of M-1 disks is tolerated at most.

Which of the following statements about Huawei OceanStor 6800 V5 Kunpeng are correct?

A It uses Huawei-developed Kunpeng CPUs.
B The back-end disk enclosure supports SAS 3.0 ports.
C The back-end disk enclosure supports high-speed RDMA ports.
D The high-performance and energy-saving Arm processor uses the 7 nm process to simplify the PCB design and save internal space.
