Which types of connection does OceanStor Dorado HyperReplication for NAS supports multiple DC interconnection?

Question

Options

• AParallel Interconnection
• BSerial Interconnection
• CSync replication interconnection
• DOne-to-many interconnection

• A
  78% (49)
• C
  22% (14)

Explanation

OceanStor Dorado HyperReplication for NAS supports three physical or logical interconnection topologies for multiple data center (DC) scenarios: Parallel Interconnection (A), where DCs are connected side by side and can replicate concurrently; Serial Interconnection (B), also called cascade, where data flows through a chain of DCs in sequence; and One-to-many Interconnection (D), where a single primary DC replicates to multiple secondary DCs simultaneously. Option C, "Sync replication interconnection," is incorrect because synchronous replication describes the timing method of data transfer (write confirmed only after remote site acknowledges), not a DC connection topology -- it is a replication mode, not an interconnection type, and therefore does not belong in a list of multi-DC connection architectures.

Memory tip: The three correct answers all describe the physical or logical shape of how DCs are wired together (side-by-side, chain, or hub-and-spoke). Sync replication describes when data is confirmed, not how the sites are connected -- if an answer describes timing or data consistency rather than network layout, it is not an interconnection type.
