Asynchronous replication also involves an ACK. It’s just not immediate like synchronous is. Please correct me if I’m wrong.
I think the question is meant to address whether the system that is performing a write to disk needs to wait for an ACK from the replication being completed before the write is considered complete. For instance, if I have a system in Los Angeles and a replicated copy of the data in San Francisco, the system does not get an ACK until the data is written to the storage in *both* Los Angeles *and* San Francisco.
Passed SG0-001 exam last weekend. Scored 850/900!
Total 100 multiple choice questions, and got all questions from passleader SG0-001 dumps (pdf and vce dumps: https://tr.im/650aU), 100% valid!
And, the SG0-001 exam not be available after January 15, 2016, and will not be replaced.
Good Luck!
