True

False

7. Which of the following description about Huawei OceanStor V3 cascade 3DC and parallel 3DC is correct? (Multiple Choice)

No matter parallel 3DC or cascade 3DC, if synchronous replication between sites is recommended to adopt fiber connection, asynchronous replication can be used ISCSI link.

In Parallel 3DC networking, because the production sites storage systems took on two remote replication data synchronization tasks, the impact on the production center storage system performance is greater than the cascade 3DC network.

in parallel 3DC, it may be affecting the normal operation of the entire disaster recovery system because a single site fails, so compared to the cascade, reliability is worse.
