A.In terms of media deduplication, in-line processing provides higher data transmission performance than post processing.

B.Media deduplication saves bandwidth resources and does not consume resources at the source end.

C.Client deduplication is implemented as follows: At the source end, hash comparison is performed for data blocks to be transmitted. If a data block has been transmitted, only the corresponding hash index value will be transmitted.

D.Client deduplication consumes resources at the source end but saves bandwidth resources.

A.The front-end business network switches can be stacked, but the back-end storage network switches are not recommended for stacking

B.To meet management requirements, only the first three nodes of the cluster need to be connected to the management network

C.Whether it is a front-end business network or a back-end storage network, it is recommended to use two switches to connect all nodes to achieve redundancy

D.Only the storage node needs to be connected to the management network, other devices do not need to be connected to the management network

A.Full backup > differential incremental backup > cumulative incremental backup
