A financial customer has purchased several Huawei OceanStor Dorado series storage devices for mission-critical service deployment. SmartMigration is configured to migrate services from a source LUN to a target LUN without interrupting host services. Which of the following statements about this feature is false?

• A.The implementation of a SmartMigration task between heterogeneous storage systems depends on the LUN takeover function provided by SmartVirtualization.
• B.When configuring this feature, you must plan the capacities of the source and target LUNs. The capacity of the target LUN must be greater than or equal to that of the source LUN.
• C.When configuring this feature, you cannot use a LUN that has been mapped to an application server as the target LUN of a SmartMigration task.
• D.The higher the migration rate, the better the host service performance is. Therefore, the highest migration rate can be used when the host service load is heavy.

When delivering a Huawei OceanStor Pacific storage project, a Huawei engineer vigorously promoted the SmartEncryption feature of scale-out storage to customers. Which of the following statements is false about this feature?

• A.The file service client can write plaintext data through the NFS/CIFS/DPC protocol.
• B.This feature supports encrypted data write using NFS, CIFS, HDFS, or S3. Data is decrypted and read using NFS, CIFS, HDFS, or S3.
• C.When the data is read using the DPC or NFS protocol, the SED obtains the identity authentication key from the key management server, reads and decrypts the ciphertext data, and then returns the plaintext data to the protocol layer. The protocol layer returns the plaintext data to client applications.
• D.Huawei OceanStor Pacific series scale-out storage supports disk encryption. All data delivered by services is stored on self-encrypting disks (SEDs).

Assume a government office purchases a Huawel OceanStor Pacific 9550 storage device. During an Inspection, an engineer notices the IAN on motherboard (LOM) optical port Indicator on the rear panel of the device Is steady yellow. This indicates that data is being transmitted at a rate of 25 Gbit/s.

• A.TRUE
• B.FALSE

In actual service scenarios, the HyperMetro feature of Huawei OceanStor Pacific series supports incremental synchronization. If a site fails, the site that wins arbitration continues providing services, and I/O requests change from the dual-write state to the single-write state. After the faulty site recovers, data generated during the fault can be synchronized to the recovered site.

• A.TRUE
• B.FALSE

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.Backup storage supports deduplication and compression of file systems.
• B.During similarity-based deduplication in the background, the system does not divide data into blocks and can directly calculate similar fingerprints.
• C.During inline deduplication, the system divides data into blocks and then calculates fingerprints for the blocks.
• D.Post-process compression means that data is first written to storage media and then read for compression.
