Huawei's hyper-converged storage has multiple data security assurance mechanisms. The following statement is correct ()

A.

Support a variety of EC (Erasure Code) with different ratios

B.

According to the security level, 2 copies or 3 copies can be flexibly configured

C.

Support storage dual-active and asynchronous replication capabilities, and provide cross-site data redundancy protection

D.

PCle SSD Cache technology ensures that data will not be lost after power failure

The remote replication feature is mainly used in disaster recovery and backup scenarios. Which of the following statements about the remote replication feature is correct:

A.

During the remote replication process, if the replication link fails suddenly, the slave L data will be unavailable.
