Assume a financial customer purchased multiple Huawei flash storage devices for routine service deployment. Which of the following statements is false about service system characteristics in financial scenarios?

A. The database OLTP service mainly involves random small I/Os and a few sequential write I/Os.
There are more read operations than write operations, and hot data areas are clear.

B. Document imaging services mainly involve sequential read of large I/Os, a few metadata operations, and 90% GB-level large file write operations.

C. Backup and archiving services mainly involve sequential large I/Os. Writes are involved in backup and archiving services, and reads are involved in restoration services.

D. The database OLAP service involves sequential read of large I/Os. The amount of data processed per batch determines hot data areas.

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

B. 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.

C. 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.

D. 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.

An airport customer has purchased several Huawei OceanStor Pacific scale-out storage devices for service deployment. To ensure service reliability, an engineer has configured the HyperReplication feature on the storage devices and established a remote replication pair between the namespaces of the primary and secondary storage systems. Which of the following statements is true about the running statuses of the remote replication pair?

A. If the running status of the remote replication pair is "Split", this indicates that the remote replication link is down or an internal I/O error has occurred. In this case, the pair cannot be synchronized or deleted.

B. If the running status of the remote replication pair is "Synchronizing", this indicates that data is being synchronized from the primary namespace to the secondary namespace. In this case, the engineer can enable the protection for secondary resources on the secondary storage system.

C. If the running status of the remote replication pair is "To be recovered", this indicates that the internal I/O error of the remote replication pair has been rectified. Data consistency between the primary and secondary storage systems is guaranteed by automatic synchronization.

D. If the running status of the remote replication pair is "Interrupted", this indicates that an internal I/O error has occurred or the remote replication link is down. As a result, the pair relationship is interrupted.
