How many destination systems does a synchronous replication session support?

Question

Options

• A1
• B2
• C4
• D8

• A
  94% (51)
• B
  2% (1)
• D
  4% (2)

Explanation

Synchronous replication requires that every write be confirmed by the destination before the source acknowledges it as complete, creating a tightly coupled, one-to-one relationship - meaning only 1 destination system is supported (A). Options B, C, and D are incorrect because adding multiple destinations would require the source to wait for acknowledgment from all of them simultaneously, multiplying latency to an impractical degree and defeating the purpose of synchronous consistency guarantees. Asynchronous replication is the technology that scales to multiple destinations, since it doesn't block on remote confirmation. Memory tip: Think "sync = single handshake" - synchronous replication is a strict two-way conversation between exactly one source and one destination, with no room for a third party to join.
