What type of deduplication does the following describe?
Dab blocks are directly stored to the cache when the system is busy and will be deduplicated during off-peak hours. The advantage is that data transmission performance is not affected. The disadvantage is that the extra storage space is required.

• A.Global deduplication
• B.Inline deduplication
• C.Parallel deduplication
• D.Post-processing deduplication

In which scenarios can OceanStor BCManager eReplication be used? (Multiple Choice)

• A.Geo-redundant DR
• B.Active-passive DR
• C.HyperMetro DC
• D.Local HA

Suppose that the amount of data is 2000 GB at site A and is 3000 GB at site B, and the deduplication ratio is 3.
If the data at site B needs to be remotely replicated to site A, how large back-end storage should be?

• A.4000 GB
• B.3000 GB
• C.2000 GB
• D.5000 GB

In OceanStor backup solution, iDA types include basic module (file system), online application backup module (including Oracle and SQL) and index cache.

• A.TRUE
• B.FALSE

The peak write bandwidth of an application is 10 MB's, the average write bandwidth is 200 KB's, and the average write IO size is 4 KB. The overhead of private information is about 11%, and the bandwidth utilization rate is 70%. The network employs FC, and the synchronous remote replication mode (considering the overhead of private information) is enabled.
Then, which is the required network bandwidth?

• A.Equal to 128.4 Mbit/s
• B.Not lower than 64.2 Mbit/s
• C.Lower than 128.4 Mbit/s
• D.Not lower than 128.4 Mbit/s
